On 24 April 1915 Ottoman officials in Constantinople arrested hundreds of Armenian leaders, and between 0.8 and 1.2 million Armenians, by one estimate, were then sent on death marches toward the Syrian desert. The next day Australian and New Zealand troops landed on the Gallipoli peninsula, in a campaign that ended in Ottoman victory. Near Ypres, Germany used poison gas on a mass scale for the first time on the Western Front. In May a German U-boat sank the liner Lusitania off Ireland; by the main count, 1,197 of the 1,960 on board were killed. Further afield, Indian sepoys mutinied in Singapore, United States Marines landed in Haiti, and South African troops conquered German South West Africa. In December an Ottoman army laid siege to the British Indian garrison at Kut in Mesopotamia, and military leaders in Yunnan rose against Yuan Shikai, who had proclaimed himself emperor of China.

War & conflictWidely known
Ottoman authorities arrest Armenian leaders in Constantinople
· Constantinople, Ottoman Empire · Middle East
Medium confidence: rests on one source family, or a detail is uncertain.
Ottoman officials in Constantinople seized hundreds of Armenian leaders and intellectuals and deported them. Under Talaat Pasha's orders, an estimated 0.8 to 1.2 million Armenians were then driven toward the Syrian desert on death marches during 1915 and 1916.
Why it is interesting. The arrests were part of a genocide in which around one million Ottoman Armenians were murdered, mostly on death marches.
Notes and dating details
Lead gives 24 April 1915 for the arrests. Wikidata gives 1915 with a start of 1915-04-24 and an end of 1923; the infobox gives the genocide as 1915-1917. Calendar not stated in source. Merged duplicate row 1915-04-24-armenian-community-leaders-are-arrested-in-constantinople (Armenian community leaders are arrested in Constantinople). Its notes: The article gives the arrest order and first wave on 24 April 1915, with the night running into 25 April. The Armenian National Archives page also dates the arrests to the night of 24/25 April and says 25 April was a Sunday, which matches the Gregorian calendar, so no Rumi conversion is needed. It says only 'several hundred' were arrested, while the article gives 235 to 270 for the first wave. Wikidata gives the year only.
· Gallipoli Peninsula, Ottoman Empire · Middle East
Britain, France and Russia tried to force the Ottoman Empire out of the war by taking the Turkish straits. After the fleet failed in March, troops landed in April. The campaign ended in Ottoman victory.
Why it is interesting. Mustafa Kemal rose to prominence there, and the landings' anniversary is Anzac Day.
Notes and dating details
The campaign is dated from 19 February 1915, when the Anglo-French fleet opened its long-range bombardment of the outer forts, to the final evacuation on 9 January 1916 (English article infobox, lead and body). Wikidata gives 25 April 1915, the day of the landings, which is a later stage of the same campaign. No calendar conversion applies: the date comes from the Allied side, which used the Gregorian calendar, and Turkish Wikipedia gives the naval phase as starting on the same day, 19 Şubat (February) 1915. The earlier note offering 4 March 1915 as a possible Gregorian equivalent was mistaken and has been removed.
Italy and the Entente sign the secret Treaty of London
· London, United Kingdom · Europe
Britain, France and Russia concluded a secret pact with Italy in London to bring it into the war on their side, promising it territory at the expense of Austria-Hungary and the Ottoman Empire, and larger African colonies.
Why it is interesting. Italy declared war on Austria-Hungary the following month, and the unmet promises fed resentment after the war.
· Celtic Sea, near Old Head of Kinsale, Ireland · Europe
A German U-boat torpedoed the British liner Lusitania near the Old Head of Kinsale, and she sank in 18 minutes. Of 1,960 people aboard, 1,197 were killed, among them about 128 Americans.
Why it is interesting. The sinking turned opinion in many countries against Germany and contributed to America entering the war in 1917.
Notes and dating details
Casualty figures differ slightly by source: the article says 1,197 of 1,960 aboard died, about 128 of them Americans; a news summary gives 1,198 of 1,959 and 128 Americans. Both agree on the 18 minutes to sink and the date 7 May 1915.
Medium confidence: rests on one source family, or a detail is uncertain.
German and Allied forces fought for the high ground east and south of Ypres in Belgium. The battle saw Germany's first mass use of poison gas on the Western Front.
Why it is interesting. German troops released chlorine gas on the battle's first day, and by July 1915 soldiers had been given efficient gas masks.
Notes and dating details
Wikidata gives 21 April 1915 as the start, unsourced; the article gives 22 April to 25 May 1915 in the infobox and lead.
· Osowiec Fortress, Congress Poland, Russian Empire · Europe
Medium confidence: rests on one source family, or a detail is uncertain.
After German artillery fired poison gas at Osowiec Fortress, the surviving Russian soldiers, with cloths over their faces, counterattacked and routed the German troops. Almost the whole garrison was affected by the gas.
Why it is interesting. The grim name came from the bloodied, corpse-like look of the Russian soldiers.
Notes and dating details
German and Polish Wikipedia both date the attack to 6 August 1915 (German: gas attack from 4 am), so the date is supported; the Russian evacuation followed on 18 August 1915. Polish Wikipedia calls 'Attack of the Dead Men' a journalistic term used in Russian and sometimes Polish writing for the counterattack of one company of the 226th Zemlyansky regiment. The English infobox's figure of about 800 Russian gas deaths was not confirmed outside (Polish Wikipedia says over 1,600 soldiers were put out of action and nearly the whole garrison poisoned), so it is not used. Calendar not stated in the English source.
· Gorlice and Tarnów area, Galicia, Austria-Hungary · Europe
Medium confidence: rests on one source family, or a detail is uncertain.
The Central Powers opened an offensive on the Eastern Front near Gorlice and Tarnów. Planned as a minor German effort to ease pressure on Austria-Hungary, it grew into their main push of 1915 and drove the Russian armies back out of Galicia.
Why it is interesting. A limited operation turned into a collapse of the Russian lines and a long retreat deep into Russia.
Notes and dating details
Wikidata's start date is 2 May 1915 (unreferenced); its point-in-time value of 22 June 1915, imported from English Wikipedia, is the day Lemberg was entered. Infobox gives 2 May - 13 July 1915, while the lead says the actions went on until October, so no end date is stored.
Battles of the Isonzo begin between Italy and Austria-Hungary
· Isonzo Valley, Slovenia and Italy · Europe
Medium confidence: rests on one source family, or a detail is uncertain.
Italy and Austria-Hungary fought a series of twelve battles along the Isonzo river valley between 1915 and 1917. The area was the only practical one for Italian operations.
Why it is interesting. Twelve successive battles were fought in this one area between 1915 and 1917.
Notes and dating details
Start taken as the opening of the First Battle of the Isonzo, 23 June 1915 (the article's list and table, its lead's 'June 1915', and the First Battle of the Isonzo article). The infobox dates the front as a whole from 24 May 1915, Italy having entered the war on 23 May; Wikidata's 23 May has no reference.
Medium confidence: rests on one source family, or a detail is uncertain.
Date uncertainty: Some sources give 19 April as the start
Armenians in Van, with the Russian army, resisted Ottoman attempts to massacre the Armenian population of Van province during the 1915 Armenian genocide. The defense lasted into May.
Why it is interesting. Armenians defended themselves against massacre, and the episode is later cited in genocide denial.
Notes and dating details
Start day: stored as 20 April 1915. The article's siege section ('City under siege, 20 April') and the 1916 Bryce and Toynbee report ('Fighting began at Van on the 20th April') both give 20 April, as does the Near East Museum (read in the earlier pass, not reopened in this one). The article's infobox and Wikidata give 19 April, which is also the day of Djevdet's extermination order and of heavy violence elsewhere in the province, so some accounts count from there. The end is 17 May in the article body (Armenian civilian forces took control; Russian forces arrived). These English-language sources use Gregorian dates; no Old Style conversion was applied.
Medium confidence: rests on one source family, or a detail is uncertain.
British and French forces attacked German defences in Artois and Champagne between 25 September and 8 October 1915, trying to break through. The Germans contained the attacks apart from local losses; British casualties in the main and subsidiary attacks totalled 59,247.
Why it is interesting. It marked Britain's first use of gas as a weapon, and New Army divisions fought their first mass engagement there.
Notes and dating details
Infobox and lead give 25 September to 8 October 1915. The article also describes a final British attack on 13 October, under the separate Actions of the Hohenzollern Redoubt. Wikidata's main date is 1915-10-08 (imported from English Wikipedia), its start (P580) 1915-09-25 and its end (P582) 1915-10-14, both unreferenced.
Anti-war socialists meet at the Zimmerwald Conference
· Zimmerwald, Switzerland · Europe
Socialists opposed to militarism met in Zimmerwald, Switzerland, from 5 to 8 September 1915. They issued a manifesto denouncing the war and set up the International Socialist Commission.
Why it is interesting. The meeting condemned the war and exposed a split between Lenin's supporters and reformist socialists.
Fighting begins in the Sinai and Palestine campaign
· Sinai Peninsula, Egypt · Middle East
Medium confidence: rests on one source family, or a detail is uncertain.
German-led Ottoman troops crossed into the British-held Sinai Peninsula, trying and failing to seize the Suez Canal. The campaign continued until the Ottomans signed the armistice at Mudros on 30 October 1918.
Why it is interesting. This opening attack began a campaign that ended with the Ottoman cession of Syria.
Notes and dating details
The lead dates the start of fighting to January 1915; the body dates the first Ottoman attacks on the Suez Canal to 26 and 27 January 1915, followed by the principal assault on 3–4 February. Wikidata gives 28 January 1915 without a reference. The infobox gives 17 November 1914 as the start of the wider campaign.
The Golem, a German silent horror film, opens in Berlin
Stage, music & filmMedium confidence
Paul Wegener and Henrik Galeen wrote and directed this silent horror film, drawing on a Jewish folktale about Rabbi Judah Loew ben Bezalel creating the Golem to protect his people. Part of the film is lost.
Notes
Released in the US under the title The Monster of Fate. Stored date is the Berlin opening. Its day differs by source: filmportal.de and German Wikipedia give the premiere as 14 January 1915 at the U.T. Kurfürstendamm, Berlin; English Wikipedia's infobox and the Pordenone Silent Film Festival 2017 catalogue (release 15 January 1915 at the U.T. cinemas on Kurfürstendamm, Friedrichstraße and Alexanderplatz) give 15 January. Stored as January 1915. The censors passed it on 22 December 1914 (filmportal.de, Pordenone catalogue), which is not a release date. Wikidata gives only the year. Directors, writers and studio confirmed by filmportal.de.

Bohemians and Shamrock Rovers meet for the first time
SportMedium confidence
The first game between the two Dublin clubs was a Leinster Senior Cup tie on Saturday, 9 January 1915. The fixture grew into a long-running local derby.
Notes
The first game date (Saturday 9 January 1915, Leinster Senior Cup at Dalymount Park, 3-0 to Bohemians) rests on the Wikipedia article alone and was not confirmed outside it. The 2025 Aviva Stadium season opener attendance was 33,208 (Extratime).
A major earthquake struck the Marsica area of Abruzzi in central Italy, with a maximum intensity of XI. Avezzano was destroyed, and the death toll was put at about 30,000.
Notes
NOAA UTC date 1915-01-13 06:52; local time 07:52 on the same date (Italian Civil Protection gives about 7:53). Magnitude is disputed and so is left out of the title: NOAA gives 7.5, Wikipedia gives a moment magnitude of 6.7 (estimates 7.0-7.5), and the Italian Civil Protection gives 7.0. Deaths: NOAA 29,978 (deathsTotal); Wikipedia 29,978-32,610; Civil Protection says over 30,000.
The First Battle of Artois ended on 13 January 1915 after starting on 17 December 1914. French attacks against German forces on the Western Front failed to break the stalemate, and the result was indecisive.
Notes
Dates 17 December 1914 to 13 January 1915 are from the article's infobox and Wikidata (unsourced). The article's claim that it was the first offensive after the First Battle of Ypres could not be confirmed in the one outside source opened (a regional-museum summary dating the opening attack to 17-19 December 1914), so it was left out.
· Bolimów, Congress Poland, Russian Empire · Europe
Battle of Humin-Bolimów is fought on the Eastern Front
War & conflictLow confidence
German and Russian forces fought an inconclusive battle near Bolimów in Congress Poland from 14 January to 28 February 1915. Germany concentrated six divisions at the breakthrough point and readied 18,000 shells loaded with tear gas and chlorine.
Notes
Wikidata gives 31 January 1915 as a single date, imported from English Wikipedia; that is the day the main German attack opened. The article's infobox and lead give 14 January to 28 February 1915. German and Russian dates; calendar not stated in source (Russian Empire location). If the source's date is Old Style (Julian), the Gregorian date would be 27 January 1915.
Austro-Hungarian and Russian forces clash at Cârlibaba
War & conflictLow confidence
Fighting near the village of Cârlibaba, close to the Bistrița river, lasted from 18 to 22 January 1915 and ended in an Austro-Hungarian victory. Russian forces were led by Lucjan Żeligowski.
Notes
Calendar not stated in source (Romania before 1919 and Russian Empire). If the source's date is Old Style (Julian), the Gregorian date would be 31 January 1915.

Arthur Auwers, a German astronomer, died in Berlin. He was known for precise star-position measurements and for detecting the companions of Sirius and Procyon from their pull on the main stars.
Notes
Wikidata place is Groß-Lichterfelde; the article says he died in Berlin.

Thomas Merton was born in Prades, France, to Welsh-origin parents. He became an American Trappist monk, priest and writer who wrote more than 50 books.
Notes
Wikidata holds 31 January 1915 (referenced to the BnF, Britannica and other authority files) and also 15 January 1915, referenced only to BeWeB. The article and the German National Library (GND) record give 31 January 1915, kept as better supported.
Ralph Chaplin completes the song Solidarity Forever
Stage, music & filmMedium confidence
Ralph Chaplin finished the trade union anthem Solidarity Forever in Chicago in January 1915, on the day of a hunger demonstration. It was written for the Industrial Workers of the World and uses the tune of John Brown's Body.
Notes
Day disputed: the Wikipedia article's composition section gives 15 January 1915, while the IWW's history page (introduction citing Chaplin's autobiography Wobbly) says Chaplin finished it on 17 January 1915, the day of the Hunger Demonstration. Both agree on January 1915 in Chicago, so month precision is stored. Infobox gives written 1914-1915; Chaplin began it in 1913.
This American silent feature follows an Italian gondolier who emigrates to the United States and ends up a shoeshiner living in a New York tenement. Reginald Barker directed it and Thomas H. Ince produced it.
Notes
Released January 1915 per the AFI Catalog and silentera.com (copyright 7 January 1915); the article itself cites newspaper reviews from 2 to 31 January 1915, and AFI cites a Motion Picture News review of 2 January 1915. Wikipedia's infobox gives 18 June 1915, with no reference attached.
Congress authorizes Panama-Pacific commemorative coins
Economy & tradeMedium confidence
Congress passed legislation for five commemorative coins tied to San Francisco's Panama-Pacific International Exposition: a silver half dollar, a gold dollar, a quarter eagle and round and octagonal $50 pieces.
Notes
Month only: the bill was considered in the House on 4 January 1915. Coins were struck at the San Francisco mint. The 'only non-round US coin' claim in the article was not confirmed outside it (the US Mint says 'unique octagonal coin'), so the interest line uses the Mint's wording.
The silent film A Fool There Was premieres in New York
Stage, music & film
Frank Powell directed this American silent drama, which William Fox produced and Theda Bara starred in. Its release helped bring the word vamp into wider use.
Notes
Stores the New York premiere, 12 January 1915, given by both the article and silentera.com; silentera.com dates the general release only to January 1915 and the copyright to 14 January 1915. A 5-reel version was released in June 1918.

Train carrying soldiers' families plunges into a canyon in Jalisco
DisastersMedium confidence
A packed special train of twenty cars, carrying families of Carranza's troops from Colima, ran out of control on a steep descent and fell into a deep canyon. More than 600 of the 900 aboard died.
Notes
The infobox gives the location as Guadalajara, while the text places it in Jalisco between Ciudad Guzman and Sayula (the Excelsior article agrees: the Cuesta de Sayula), so the state is used as the place. The English article also ranks it as the worst railway accident in North American history; the outside source opened did not confirm that, so it was left out.
Castries, Saint Lucia, then part of the British Windward Islands, was the birthplace of William Arthur Lewis. He grew into a development economist known for his dual-sector model and was later awarded the Nobel Memorial Prize in Economic Sciences.
Robert Motherwell was born in Aberdeen, Washington. He became an American abstract expressionist painter and printmaker, among the younger artists of the New York School.

A new club was formed on 3 January 1915 by merging Lanus United, which was in financial trouble, with Club El Progreso. The name Club Atletico Lanus was officially adopted at a meeting on 27 January 1915.
Notes
Name made official 27 January 1915. Spanish Wikipedia agrees on 3 January 1915 but says several versions of the club's origins exist, the best accepted being this merger.
The Jama Masjid at Aligarh Muslim University, also known as Sir Syed Mosque, was completed. Building had begun in 1879 under the university's founder, Sir Syed Ahmad Khan.
Notes
Construction started 1879; the mosque article's text says completed January 1915 and its infobox says 1915. The month appears only in that article: the university history article says only that it was inaugurated in 1915, and no outside source confirming the month was found.
Fighting begins in the Sinai and Palestine campaign
War & conflictMedium confidence
German-led Ottoman troops crossed into the British-held Sinai Peninsula, trying and failing to seize the Suez Canal. The campaign continued until the Ottomans signed the armistice at Mudros on 30 October 1918.
Notes
The lead dates the start of fighting to January 1915; the body dates the first Ottoman attacks on the Suez Canal to 26 and 27 January 1915, followed by the principal assault on 3–4 February. Wikidata gives 28 January 1915 without a reference. The infobox gives 17 November 1914 as the start of the wider campaign.
An Ottoman operation led by the German officer Stange to seize Ardahan and cut the Russian link to the Sarikamish-Kars line ended in a Russian victory. It had run alongside the Battle of Sarikamish.
Notes
Day not settled: the infobox and lead give 25 December 1914 to 18 January 1915, but the lead also says a decisive Russian victory was achieved by 3 January 1915, and the body dates the Russians' retaking of Ardanuch (not Ardahan) to 18 January 1915 and says Stange's force took Ardahan on 27 December 1914. Wikidata also gives 18 January 1915, unsourced. The sources agree only on January 1915, so month precision is stored. Calendar not stated in source (Russian and Ottoman Empires).
The battle between Russian and Ottoman forces, begun on 22 December 1914, ended on 17 January 1915 with a Russian victory. Ottoman troops, poorly equipped for the winter, suffered heavy losses in the mountains.
Notes
The article's infobox and lead give 22 December 1914 to 17 January 1915; the calendar is not stated (Russian Empire and Ottoman Empire). One outside account (Foreign Exchanges) says the Ottoman retreat began about 7 January and that some Ottoman units held out until 17 January, so 17 January is the end of the whole operation rather than of the main fighting. The article's figure of about 25,000 frozen before the main fighting could not be confirmed outside and was left out of the interest line.
· Jarrab Lake, north of Al Majma'ah, Arabia · Middle East
Battle of Jarrab is fought near Al Majma'ah in Arabia
War & conflictMedium confidence
Forces of the Al Rashid, led by Saud bin Abdulaziz Al Rashid, defeated those of Ibn Saud near Jarrab Lake. Ibn Saud's British military adviser, Captain William Shakespear, was killed.
Notes
Wikidata gives 17 January 1915, imported from English Wikipedia with no other source. The article's infobox and lead give 24 January 1915, citing McLoughlin (1993) and Goldberg (1986), and the article on Captain William Shakespear gives his death in the battle as 24 January 1915.
A German-led Ottoman force crossed the Sinai from southern Palestine to attack the British-protected Suez Canal, and a few men got across. The attack failed, with Ottoman losses estimated at roughly 1,300 to more than 2,000 men, including 716 taken prisoner, and it opened the Sinai and Palestine campaign.
Notes
Dates: the infobox and lead give 26 January to 4 February 1915; Wikidata has the same start and end. Ottoman losses are disputed: the lead says nearly 2,000 (Bruce; Falls); British headquarters estimated more than 2,000 (Falls); Bruce gives some 1,500 including 716 prisoners; the infobox gives 784 killed or wounded and 716 captured; German Wikipedia, citing Eugene Rogan, gives Djemal Pasha's figures of 192 dead, 381 wounded and 727 missing. Ottoman side involved; dates are as given in the English-language sources.

Chilembwe uprising against British rule in Nyasaland
War & conflict
Rebels led by the Baptist minister John Chilembwe attacked the A. L. Bruce Estates headquarters at Magomero on 23 January 1915 and killed three white settlers. Colonial forces suppressed the revolt by 26 January; Chilembwe was shot dead on 3 February.
Notes
Infobox date January 23-26, 1915. About 40 rebels were executed afterwards and 300 imprisoned. German Wikipedia's article on Chilembwe also dates the start to 23 January 1915 and his death to 3 February 1915 and calls him a national hero in Malawi.
On New Year's Day 1915, Mulla Abdullah and Gool Badsha Mahomed fired rifles at a train carrying 1,200 picnickers near Broken Hill, killing four people and wounding seven before police and military officers killed them.

· Przasnysz, Congress Poland, Russian Empire · Europe
The First Battle of Przasnysz begins
War & conflictMedium confidence
German and Russian troops began fighting near Przasnysz in Congress Poland. The battle ended in a Russian victory, and German plans to encircle the Russians in Poland failed.
Notes
Dates disputed: the infobox and lead give 7-28 February 1915, while the article's short description and Wikidata (unreferenced) give 18 February - 26 March 1915. The body narrates fighting from 12 February to the recapture of Przasnysz on 27 February and mixes calendars (an order written on 24 February sets an attack for 'February 12', an Old Style date). Start stored at month level and end left open; no outside source could be opened. Russian Empire, Julian calendar in use; the article's main dates appear to be Gregorian but this is not stated.
The football club now called US Livorno 1915 was founded in Livorno, Tuscany. In the 1919–20 Italian championship it reached the final, lost to Internazionale, and finished second.
Notes
Founding day disputed: English Wikipedia's history section gives 15 February 1915 (its infobox gives only 1915); Italian Wikipedia says the club was born on 17 February 1915 from the merger of Virtus Juventusque and SPES; the fan-history site glieroidelcalcio.com says the merger agreement was signed on 14 February 1915. All agree on February 1915, so month precision is used. The club was refounded in 1991 and 2021.
In February 1915 the Jourdain brothers re-founded the newspaper in secret as an underground paper called La Libre Belgique, meaning Free Belgium. It appeared while Belgium was occupied in World War I.
Notes

Mary Elizabeth Braddon, an English popular novelist, died in Richmond, then in Surrey, and was buried in Richmond Cemetery. Her 1862 novel Lady Audley's Secret is regarded as a foundational example of sensation fiction.
Armand Peugeot, a French industrialist, died at Neuilly-sur-Seine near Paris. He had turned the family firm Peugeot into a maker of bicycles and, later, of cars.
Notes
Infobox and lead give 4 February 1915 (the lead cites the BnF), and the BnF authority record gives death on 4 February 1915 in Paris. A sentence in the family section gives 2 January 1915 with no citation; Wikidata ranks 2 January as deprecated and 4 February as normal (its cited Musee Peugeot PDF no longer loads). The BnF names Paris as the place of death; the article and Wikidata give Neuilly-sur-Seine, near Paris.
FC Wacker Innsbruck, a football club from Innsbruck in Tyrol, was established in 1915. Its founders included Jakob Hanspeter, Benedikt Hosp and Josef Leitner, and it chose black and green as colours.
Notes
4 February 1915 is the day the club's statutes were approved by the Tyrol governor's office, which German Wikipedia treats as the official founding (newspapers of 5 February 1915 reported it); the same article says the club had already played a first known game on 19 July 1914, so the founding is dated 1914 in part of it. English Wikipedia and Wikidata give 4 February 1915. Dissolution: the general meeting of 20 May 1999 decided on it. A new club of the same name was founded in 2002.
On 7 February 1915, in a heavy snowstorm, the left wing of the German 8th Army made a surprise attack on Russian trenches in East Prussia. It opened the northern part of the Central Powers' winter offensive on the Eastern Front.
Notes
Infobox gives 7 to 28 February 1915; Wikidata gives an end date of 22 February. The English article also describes it as the final large battle on German territory in the war, but the outside source opened (Mental Floss, which confirms the 7 February start) did not support that, so it was left out.
IFK Landskrona and Landskrona BK, the latter earlier called Diana BK, merged to create Landskrona BoIS. The club later joined the first Allsvenskan season, 1924-25.
Bakerloo line trains began running to Queen's Park from Kilburn Park. On 10 May 1915 services went further north over the shared Watford DC line tracks.
Notes
The station itself opened on 2 June 1879; 11 February 1915 is when Bakerloo service began. The row's kind 'opening' is therefore not an opening of the station.
Émile Waldteufel, a French composer, pianist and conductor, died. He was known for popular salon pieces, among them the waltz "Les Patineurs" (1882).
Notes
The English body puts his death at his residence at no. 37, rue Saint-Georges, Paris; French Wikipedia (citing the Paris death record, act 142 of 1915) gives the 9th arrondissement of Paris. Wikidata also gives Paris.
French and German forces fought a series of engagements on the ridge near Les Éparges in the Meuse Heights. The French wanted the high ground to give their artillery a view over the Woëvre Plain.
Notes
Wikidata gives a single date, 5 April 1915 (imported from French Wikipedia without a source), which is the day the April offensive began; the article's infobox and lead both give 17 February to 9 April 1915.
William Fox formed the Fox Film Corporation in 1915 as the successor to two companies he had run before: Greater New York Film Rental and Box Office Attraction. Its first film studios were in Fort Lee, New Jersey.
Notes
Date 1 February 1915 is in the article infobox and in the Silent Era company list (French Wikipedia also says 1 February 1915). The infobox puts the founding in Fort Lee, but Silent Era lists the earliest company office as 130 West 46th Street, New York (c. 1915-1917), so the place of formation is not settled; Fort Lee is kept as the place of the first studios. The article notes 20th Century-Fox long claimed 1915 as its founding year.
His New Job is a short silent comedy written and directed by Charlie Chaplin. The title refers to Chaplin's move from Keystone Studios to Essanay, and it was shot at Essanay's Chicago studio.
Notes
Stores the US release, 1 February 1915, given by both the article and silentera.com; silentera.com adds releases in Sweden (30 August 1915) and Spain (22 December 1915). Filmed in January 1915 at Essanay's Chicago studio; the release was not a Chicago opening, so the place is the country.
German agent bombs the Vanceboro railway bridge on the US-Canada border
War & conflict
Werner Horn set off a bomb at the Saint Croix-Vanceboro Railway Bridge between Maine and New Brunswick, in a plot masterminded by Franz von Papen. The bridge survived but was unsafe to use until minor repairs were made.
Venustiano Carranza, leader of the Constitutionalist Army, founded the Military Aviation Arm. It later became the Mexican Air Force.
Notes
The infobox gives a start date of 1913 and an anniversary of 10 February; the history text of the English article and Spanish Wikipedia date the founding of the Military Aviation Arm (Arma de Aviacion Militar) to 5 February 1915.
Robert Hofstadter was born in New York City to Polish Jewish immigrants. He became an American physicist and shared the 1961 Nobel Prize in Physics for studies of electron scattering in atomic nuclei.

Fanny Crosby dies
Lives
Fanny Crosby died in Bridgeport, Connecticut. An American poet and lyricist, she was the author of over 8,000 hymns and gospel songs.
Notes
The article's '100 million copies' (an estimate) and 'nearly two hundred pseudonyms' were not confirmed outside Wikipedia, so they are left out; the 8,000+ hymns, the date and Bridgeport are confirmed by the NetHymnal biography. The article also says 'almost 9,000' elsewhere and a footnote cites 8,440.
A Night Out is a Charlie Chaplin comedy short, also starring Ben Turpin, Leo White and Bud Jamison. It was his first film with Edna Purviance and his first made at the Essanay studio in Niles, California.

· Kearney, Missouri, United States · North America
Frank James dies
LivesMedium confidence
Frank James, a Confederate guerrilla who became an outlaw after the Civil War and the older brother of Jesse James, dies aged 72. He had ridden with the James–Younger Gang.
Notes
Infobox and Wikidata give Kearney, Missouri. The body says he returned to the James Farm in his last years and died there at age 72 on 18 February 1915; the nearby mention of Washington state refers to 1914 berry-picking and does not change the place. New World Encyclopedia also gives 18 February 1915, aged 72, at the James Farm in Clay County, Missouri (it does not name Kearney). Confidence stays medium only because the town comes from the infobox and Wikidata, not the body text.
San Francisco hosts the Panama-Pacific International Exposition
Everyday life
San Francisco held a world's fair from 20 February to 4 December 1915, officially to mark the completion of the Panama Canal. Many in the city also treated it as a chance to show how far it had recovered from the 1906 earthquake.

The Valley of Fear is published as a book in New York
Art & literatureMedium confidence
Arthur Conan Doyle's fourth and final Sherlock Holmes novel came out as a book from George H. Doran Company in New York. It had been running as a serial in The Strand Magazine since September 1914.
Notes
First British book edition: Smith, Elder & Co., 3 June 1915. Serialised in the Strand from September 1914 to May 1915; first edition copyrighted 1914. The 27 February 1915 day for the New York Doran edition comes from the article body (infobox gives only 1915); no outside source for the day was found in one search, so confidence is medium.
Liverpool Fútbol Club was founded in Montevideo, Uruguay. Its first promotion to the Primera División came in 1919, and home games are at Estadio Belvedere.
Peter Medawar was born in Brazil. He became a biologist whose work on immune tolerance and graft rejection shaped tissue and organ transplantation.
Notes
Birthplace disputed: the Nobel Prize biography says Rio de Janeiro; the article says he is stated to have been born in Rio de Janeiro and elsewhere in Petrópolis; Wikidata lists both (Petrópolis preferred). Place stored at country level. Date 28 February 1915 agrees across sources.
Ghadar Mutiny plot targets the British Indian Army
War & conflictMedium confidence
A plan was set for February 1915 to start a mutiny across the British Indian Army and end British rule in India. Backed by the Ghadar Party, the Berlin Committee and German officials, it was thwarted by British intelligence and police action.
Notes
Month is when the mutiny was planned to begin; Wikidata also gives 1915-02.
Aung San was born in Natmauk in Burma. He became a politician and independence activist who worked to end British rule and is regarded as the founder of the Tatmadaw.
Sepoys of the 5th Light Infantry mutiny in Singapore
War & conflict
Up to half of the 5th Light Infantry, a British Indian Army regiment in Singapore, mutinied after rumours they would be sent against the Ottoman Empire. Dozens of soldiers and civilians were killed by the mutineers before it was put down.
Notes
Wikidata gives an end date of 1915-02-22 (unsourced). Number killed differs by source: English Wikipedia says 36 soldiers and civilians, the National Library Board's Infopedia says 44 British and 5 Chinese or Malay civilians (49). Infopedia confirms 15 February 1915 as the start and 47 executions (Kassim Mansoor hanged on 31 May), and its totals (47 executed, 165 more sentenced) are consistent with 'more than 205' tried.
Gopal Krishna Gokhale, a senior Indian National Congress leader and social reformer, dies. He had founded the Servants of India Society.
Notes
Place of death disputed: the article's infobox gives Bombay (uncited); Nordisk familjebok and, per Wikidata, the Great Soviet Encyclopedia give Poona (Pune). Both lie in the Bombay Presidency, which is stored.
· Gallipoli Peninsula, Ottoman Empire · Middle East
The Gallipoli campaign begins
War & conflict
Britain, France and Russia tried to force the Ottoman Empire out of the war by taking the Turkish straits. After the fleet failed in March, troops landed in April. The campaign ended in Ottoman victory.
Notes
The campaign is dated from 19 February 1915, when the Anglo-French fleet opened its long-range bombardment of the outer forts, to the final evacuation on 9 January 1916 (English article infobox, lead and body). Wikidata gives 25 April 1915, the day of the landings, which is a later stage of the same campaign. No calendar conversion applies: the date comes from the Allied side, which used the Gregorian calendar, and Turkish Wikipedia gives the naval phase as starting on the same day, 19 Şubat (February) 1915. The earlier note offering 4 March 1915 as a possible Gregorian equivalent was mistaken and has been removed.
Ships of the Royal Navy, French and other Allied navies attempted to break through the narrow Dardanelles waterway against the Ottoman Empire. Ottoman defenders, mainly using naval mines, defeated the effort.
Notes
The infobox gives 19 February - 18 March 1915 and the body describes the first shots on 19 February 1915, when two destroyers probed the straits; Wikidata also gives 19 February (unreferenced). The lead gives 17 February 1915 - 9 January 1916, but nothing in the body supports 17 February, so 19 February is used. No outside source could be opened to cross-check. Calendar not stated in source.
John Chilembwe, a Baptist pastor from Nyasaland, was killed by colonial forces shortly after leading an unsuccessful armed uprising against colonial rule. He is remembered as an independence hero in some African countries.
Notes
Place of death disputed: the infobox says near Mulanje, Nyasaland, while Store norske leksikon (also cited on Wikidata) gives Blantyre. The article's text says a patrol tracked him down and killed him as he apparently tried to escape into Mozambique. Stored at country level.
The pro-German Boer uprising in South Africa, which began in September 1914, was over by early February 1915, when General Kemp surrendered. The ringleaders received heavy fines and prison terms, and one, Jopie Fourie, was executed.
Notes
Infobox gives the rebellion as 15 September 1914 to 4 February 1915; Kemp's surrender is dated 4 February 1915 in the text.
A German force under Major Ritter attacked Kakamas, hoping to take two fords over the Orange River. South African troops held the fords and stopped the Germans crossing, and the Germans withdrew across the border.
Notes
The article describes it as a skirmish for control of two fords; the earlier wording that it kept the Germans from moving deeper into South Africa went beyond the article and was removed.
An annular solar eclipse, magnitude 0.9789, was visible as a ring from Australia, Dutch East Indies Papua, German New Guinea and islands in what are now the Federated States of Micronesia and the Marshall Islands. A partial eclipse reached parts of Antarctica, Oceania and Southeast Asia.
Notes
Eclipse fell on 13 February only in a small area east of the International Date Line. Date (14 February), type, magnitude and an Australian annularity path confirmed by photoephemeris.com. The article's phrase 'Japanese-held South Seas Mandate' was dropped because that mandate did not exist until after the war.
Ford Madox Ford's novel The Good Soldier is published
Art & literature
The British writer Ford Madox Ford's novel tells the tragedy of Edward Ashburnham and his apparently perfect marriage through flashbacks and an unreliable narrator. It was published by John Lane, The Bodley Head.
Jacques Chaban-Delmas is born in Paris. He became a Gaullist politician, serving as Prime Minister of France from 1969 to 1972 and as Mayor of Bordeaux from 1947 to 1995.
British forces attacked German lines at Neuve-Chapelle in Artois, France, and broke through defences in a salient at the village. The success could not be exploited, and the fighting ended on 13 March.
Notes
Article gives the battle as 10-13 March 1915; date_end taken from it.
Sergei Witte dies in Petrograd. He had been the Russian Empire's first prime minister and earlier its finance minister, when he oversaw extensive industrialisation.
Notes
Gregorian (New Style) date; Old Style (Julian) 28 February 1915. The full article marks 13 March 1915 as Gregorian with its Julian equivalent, and Wikidata also gives 28 February 1915, the O.S. date; the body's 'died in February 1915' is the Old Style month. Infobox gives brain tumor as cause of death; the body says meningitis or a brain tumor.
Walter Crane dies at Horsham Hospital in West Sussex, three months after his wife. He was an English artist and illustrator, and an advocate of democratic socialism.
The First Battle of Champagne, fought by French Fourth Army troops against German 3rd Army forces, ended inconclusively in March 1915. It began on 20 December 1914 as part of a French plan to attack the Noyon Salient.
Przemyśl garrison surrenders to Russia, ending the siege
War & conflictMedium confidence
The Austro-Hungarian garrison of the fortress town of Przemyśl surrendered to Russian forces after a siege of 133 days in total. The siege was a crushing defeat for the Austro-Hungarian army.
Notes
Surrender is dated 22 March 1915 in the article's infobox, lead and Wikidata and in Dowling's ABC-CLIO entry it cites. The article's own body dates the capture of nine Austro-Hungarian generals to 9 March 1915, which is the same day in the Julian (Old Style) calendar, so 22 March is the Gregorian date. Polish Wikipedia's text says the capitulation was signed at 06:00 on 23 March 1915 after the forts were blown up on 22 March; the surrender is stored as 22 March.
Rachmaninoff's All-Night Vigil is first performed in Moscow
Stage, music & film
Sergei Rachmaninoff's a cappella choral work, his Op. 37, was first performed in Moscow, partly to benefit the Russian war effort. He had composed it in less than two weeks.
Notes
Source gives 10/23 March 1915, so the Old Style date is 10 March; 23 March is the Gregorian date used.
· Yeleninskoye, Orenburg Governorate, Russian Empire · Europe
Vasily Zaytsev is born
LivesLow confidence
Vasily Zaytsev was born in Yeleninskoye, Orenburg Governorate. He became a Soviet sniper in World War II.
Notes
Calendar not stated in source; Russian Empire at the time, and Wikidata gives the same day, 23 March 1915 (referenced to Find a Grave and TracesOfWar). Wikidata's unreferenced birthplace Yeleninka is the same village: Wikipedia's Yeleninskoye redirects to Yeleninka (also called Yeleninskoye), a selo in Kartalinsky District, Chelyabinsk Oblast, at 53°07'N 59°53'E. No source opened says which side of the Europe-Asia boundary it lies on, so region Europe is unconfirmed and may need to be Asia. If the source's date is Old Style (Julian), the Gregorian date would be 5 April 1915.
· Near Mexican Hat, San Juan County, Utah, United States · North America
Bluff War ends in Utah
War & conflictMedium confidence
The Bluff War between Ute and Paiute bands and a posse around Bluff, Utah, ended in March 1915. After talks at General Hugh L. Scott's camp near Mexican Hat, Polk and Posey agreed to give up Tse-ne-gat, who was accused of murdering a shepherd.
Notes
The infobox gives the conflict as March 1914 to March 11, 1915, and Wikidata copies 11 March. But the article's Surrender section says Scott left Bluff for Mexican Hat on 11 March; no one came to his camp until the third day, and Polk and Tse-ne-gat came the day after that, so the surrender came several days after 11 March. Stored as March 1915. Infobox location: San Juan County, Utah and Montezuma County, Colorado.
Congress establishes the National Advisory Committee for Aeronautics
Technology
A United States federal agency for aeronautical research was created by an act of Congress, attached as a rider to the 1915 naval appropriations bill. Its committee had 12 members.
Notes
Act approved 3 March 1915 (NASA history confirms the date, the naval-appropriations rider and 12 members). The article's 'unpaid' members and '$5,000 a year' budget (from one cited source) were not confirmed outside and are left out.
The Champion is a two-reel silent comedy short from Essanay Studios with Charlie Chaplin, Edna Purviance and Leo White. Broncho Billy Anderson, who co-owned Essanay, can be spotted cheering in a boxing scene.
Notes

Carl Laemmle opens Universal Studios in Universal City
Stage, music & filmMedium confidence
Carl Laemmle, who had bought a San Fernando Valley ranch in 1914 and founded Universal City there, opened Universal Studios with a grand opening that lasted two days and drew 10,000 people.
Notes
The article's history section says Laemmle opened the studio on 14 March 1915 with a two-day grand opening (so 14–15 March); its infobox and Wikidata (imported from English Wikipedia) give 15 March 1915 for the Los Angeles studio lot. Wikidata also lists 30 April 1912 (as a movie studio) and 15 July 1964 (as a theme park).
Two children are murdered on Manhattan's East Side
Everyday life
Two young children, a girl on 19 March and a boy on 3 May 1915, were fatally stabbed in Manhattan tenement hallways on the East Side. Letters signed Jack the Ripper reached their mothers, and the killings were never solved.
Notes
Five-year-old Leonore Cohn was attacked about 7:30 p.m. on 19 March 1915 and died soon after being found; four-year-old Charles Murray was killed on 3 May 1915 (article body, citing contemporary newspapers). Wikidata gives only the year 1915, unsourced.
A British squadron fought the German light cruiser Dresden off Más a Tierra, an island belonging to Chile. Dresden was cornered in Cumberland Bay and scuttled, wiping out what remained of the German East Asia Squadron.
Sir Reginald Craddock, home member of the Viceroy's council, introduced an emergency criminal law that the council passed at one sitting. It allowed preventive detention, internment without trial and limits on writing, speech and movement.
Mosaburo Makita, born in 1893, started a company in Nagoya that sold and repaired lighting equipment, motors and transformers. It later became Makita, a power tool maker based in Anjō.
Notes
Lead gives 21 March 1915; the infobox and Makita's own history page give only March 1915 (founded in Nagoya by Mosaburo Makita as a sole proprietorship), so the day rests on the article lead alone. The 'factories in eight countries' claim was dropped as unconfirmed outside Wikipedia.
Sultanate of Sulu's sovereignty ends with the Carpenter Agreement
Politics & diplomacy
Under pressure from American commanders, Sultan Jamalul Kiram II signed the Carpenter Agreement, giving up sovereignty over lands controlled by the United States and keeping only his religious role as head of Islam in Sulu. The sultanate lived on as a ceremonial institution.
Notes
Day from the full article's history section (it says the sultanate in effect stopped existing on 22 March 1915 through the Carpenter Agreement), matching the infobox end date of 22 March 1915; the lead says powers were given up 'by 1915'. Wikidata gives 1915. The infobox's 23 July 1914 date belongs to a separate event. Candidate place (East Kalimantan) not used.
Locust swarms strip vegetation across Ottoman Syria
DisastersMedium confidence
From March to October 1915, locust swarms ate nearly all the vegetation in parts of northern present-day Israel, Palestine, Mount Lebanon and Syria. Historian Zachary J. Foster says fruit and vegetable harvests were wrecked by 60 to 100 per cent.
A French law created the Croix de guerre in April 1915. The decoration honoured French and allied soldiers cited for valorous service in the First World War.
Notes
Date disputed: English Wikipedia gives 2 April 1915 as the day the bill passed (introduced 18 January 1915), and its infobox gives established 2 April 1915; the French government's Chemins de mémoire site says a law of 8 April 1915 established the medal. Both are April 1915, so month precision is used. Wikipedia's total of 2,065,000 awards differs from the 2,055,000 citations the Ministry of War counted on 1 March 1920 (a count the site says excludes some awards), so a rounded figure is used. Q869896 is a duplicate in this pack.
Isaac Leib Peretz, a Polish Jewish writer and playwright who wrote in Yiddish, died in Warsaw. He is counted among the three great classical Yiddish writers.
Notes
Calendar resolved: Wikidata also lists 21 March 1915 (unsourced, from Wikipedia), which is the Old Style (Julian) equivalent of 3 April 1915. German Wikipedia and the Jewish Historical Institute in Warsaw give 3 April 1915, and Wikidata's preferred, referenced value is 3 April, so 3 April is stored as the Gregorian date. The English body text gives only 1915; the day comes from the lead and infobox. Confidence is medium because the Institute's page does not state its calendar.
British government sets up the De Bunsen Committee on Ottoman policy
Politics & diplomacy
On 8 April 1915 Prime Minister H. H. Asquith established a committee under Maurice de Bunsen to settle Britain's policy toward the Ottoman Empire. It reported on 30 June 1915.
British forces, using mines laid by tunnellers, attacked Hill 60 on 17 April and seized it quickly with only seven casualties, but holding the salient proved costly. German attacks in early May, with gas shells, recovered the ground.
Notes
Infobox lists 17-22 April and 1-7 May 1915; Wikidata gives 7 May with other dates 17 April and 22 April. The Germans recovered the ground on 5 May.
German and Allied forces fought for the high ground east and south of Ypres in Belgium. The battle saw Germany's first mass use of poison gas on the Western Front.
Notes
Wikidata gives 21 April 1915 as the start, unsourced; the article gives 22 April to 25 May 1915 in the infobox and lead.
Two Canadian battalions, with some French colonial troops, fought at Kitcheners' Wood near Ypres, part of the Second Battle of Ypres, following Germany's first poison gas attack on the Western Front. The Canadians won, but over 75% of them were killed or wounded.
Rupert Brooke, the English poet of the war sonnets "The Dead" and "The Soldier", died of septicaemia after a mosquito bite, aboard a French hospital ship anchored off the Greek island of Skyros.
Notes
Article footnote: 23 April 1915 is the Gregorian date; under the Julian calendar then used in Greece it was 10 April. He died at 4:46 pm aboard the French hospital ship Duguay-Trouin, moored in a bay off Skyros in the Aegean Sea; the infobox gives Skyros, Greece. Wikidata gives the Aegean Sea (unreferenced) and lists Skyros as deprecated.
Sheffield United beat Chelsea in the 1915 FA Cup final
Sport
Sheffield United beat Chelsea 3-0 at Old Trafford in Manchester before 49,557 people. Many in the crowd were soldiers, so the match was nicknamed the Khaki Cup Final.
Italy and the Entente sign the secret Treaty of London
Politics & diplomacy
Britain, France and Russia concluded a secret pact with Italy in London to bring it into the war on their side, promising it territory at the expense of Austria-Hungary and the Ottoman Empire, and larger African colonies.
Alexander Scriabin, a Russian composer and pianist, died in Moscow. His music moved from a late-Romantic style toward a dissonant language built on his own metaphysical ideas.
Notes
The article's lead gives 27 April 1915 in a Gregorian-to-Julian template, so it is New Style (O.S. 14 April 1915); German Wikipedia also gives 27 April 1915 as the Gregorian date. The body's dates (last concert 2 April, death 14 April, funeral 16 April) are Old Style; Russian Wikipedia gives the last concert as 2/15 April, so it fell 12 days before his death. Wikidata also gives 27 April but flags its value as Julian.
International Congress of Women meets at The Hague
Politics & diplomacy
More than 1,100 delegates from neutral and warring countries gathered at The Hague for the International Congress of Women. They set up a permanent women's peace committee, the ICWPP, with Jane Addams as its president.
Notes
The article body says the congress opened on 28 April 1915 (citing history.com). Wikidata also lists 28 April as start and 30 April as end, both unsourced; the end date is not stated in the article, so it is left empty.
Russian troops attacked to gain control of a height in the Beskids part of the Carpathians, near Slavsko. Austro-Hungarian defenders included Ukrainian Sich Riflemen. The Russians took the height but could not follow up with a major offensive.
Notes
Infobox gives 28 April - 4 May 1915 with Old Style 14 - 22 April; the full article has the Russian storming starting on the night of 28 to 29 April and Makivka taken on 4 May. The two sets do not match the 13-day offset exactly (14 and 22 April Julian would be 27 April and 5 May Gregorian), so the dates may be a day out. Wikidata gives 14 - 22 April with no reference, the same figures as the Old Style dates. The Gregorian dates stated in the article are used.
South Slav exile politicians formally set up the Yugoslav Committee at the Hôtel Madison in Paris. It aimed to detach South Slav lands from Austria-Hungary and unite them with Serbia.
Notes
The article, citing Boban (2019) and Machiedo Mladinic (2007), places the formal founding on 30 April 1915 at the Hotel Madison in Paris, shortly after the Treaty of London of 26 April; the committee named London as its seat. Croatian Wikipedia gives 30 May 1915 in Paris (probably a slip, since its own text places the founding after the 26 April treaty), and a Croatian journal article says the official emigrant committee was formed only at the end of 1915 in London. The cited-scholarship value of 30 April is kept, with these competing dates noted. Wikidata's place (Austria-Hungary) was replaced with Paris, as in the article.
Edgar Lee Masters's collection of free verse poems, written as epitaphs of the residents of a fictional small town, appeared in book form from Macmillan. It had first run in a St. Louis journal.
Notes
Infobox release date April 1915; month precision used (a rare-books listing confirms Macmillan, New York, 1915 but gives no month). The infobox short description calls it a 1916 poetry collection, but the lead and release date give 1915. Serial publication in Reedy's Mirror ran from 29 May 1914 to 5 January 1915. Poem counts (212 characters and 244 accounts in the lead, 213 poems in the first edition and 33 added in 1916 in the body) do not add up and were left out.
Constitutionalist forces under Álvaro Obregón fought Pancho Villa's División del Norte near Celaya, in Guanajuato, Mexico. Obregón's defensive trenches and machine guns defeated Villa's cavalry charges.
Notes
Infobox gives 6-15 April 1915. Lead says the first battle was 6-7 April and the second 15-16 April, while body text has the second beginning 13 April, so no end date is stored. Wikidata gives 6 to 15 April.
William Hale Thompson wins the Chicago mayoral election
Politics & diplomacy
William Hale Thompson, a Republican, beat Democrat Robert Sweitzer for mayor of Chicago. It was the city's first mayoral election after Illinois granted women partial suffrage.
Notes
Date 6 April 1915 and the two candidates confirmed by the Chicago Public Library's Thompson biography. The article's 89% turnout, its claim of more voters than any earlier US municipal election, and the 240,000 women voters were not confirmed outside Wikipedia and are left out; the margin is computed from the infobox totals (398,538 to 251,061).

Holiday, born Eleanora Fagan, was born in Philadelphia. She became an American jazz and swing singer, nicknamed "Lady Day".
Notes
Birthplace is disputed. The article says Philadelphia (citing her biographer Stuart Nicholson, who drew on three sources, per jazz.com) and mentions that a birth certificate held in the Baltimore archives names a different father; Baltimore, where she grew up and where her statue stands, is often given as her birthplace, and Wikidata lists both (Philadelphia preferred). Philadelphia kept as the better-researched value. Date 7 April 1915 agrees across sources.

Lives
Morgan, born Harry Bratsberg, was born in Detroit. He became an American actor whose film and television work spanned six decades, including a starring role in M*A*S*H, where he played Colonel Sherman T. Potter.
Notes
Birth date, Detroit and the M*A*S*H and Dragnet roles are in the article; Playbill's obituary also confirms the Potter and Gannon roles and 'more than 100 movies' (the '100 films' figure is not in the Wikipedia article). Playbill's printed birth year is a typo.
Charlie Chaplin wrote and directed The Tramp, a two-reel silent film for Essanay Studios, and played its title character, with Edna Purviance as the farmer's daughter.

Anthony Quinn was born Manuel Antonio Rodolfo Quinn Oaxaca in Chihuahua City, Mexico. He grew up in El Paso and East Los Angeles and became a Mexican and American actor in over 100 roles.
Notes
Birth date, Chihuahua City and the first Oscar for Viva Zapata! (Best Supporting Actor, 1952) are in the article; the Academy's 1953 ceremony page confirms the Oscar.
Elias Montenegro, Dino Belo, Antonio Lima and others founded Campinense as a dancing club in Campina Grande, Paraiba. It is now a football club.
Notes
Founding date 12 April 1915 and the dancing-club origin are in the English article and in Portuguese Wikipedia, which says it was founded that day by 29 people as a recreational dancing society. Wikidata gives 1915 only.
The first section of what became the Seibu Ikebukuro Line, from Ikebukuro in Tokyo to Hannō, was opened by the company that preceded today's Seibu Railway.
Notes
It opened on 15 April 1915 as the Musashino Line of the Musashino Railway, a forerunner of today's Seibu Railway, running first between Ikebukuro and Hannō; the Japanese Wikipedia infobox also gives 15 April 1915. Wikidata agrees.
At Shaiba in Ottoman Iraq, British-Indian forces fought Ottoman troops and Al-Muntafiq fighters during an Ottoman attempt to retake the city of Basra. The British-Indian side won.

Sultan Hussein Kamel establishes the Order of Ismail
Politics & diplomacy
Sultan Hussein Kamel of Egypt established the Order of Ismail, a state honour meant to reward eminent services to the state. It ranked just below the Order of Muhammad Ali.
Notes
14 April 1915 is stated in both the English and Italian Wikipedia articles (the Italian cites medals.org.uk); Wikidata agrees. The order ranked directly below the Order of Muhammad Ali per the infobox.
Armenians in Van, with the Russian army, resisted Ottoman attempts to massacre the Armenian population of Van province during the 1915 Armenian genocide. The defense lasted into May.
Notes and dating
Date uncertainty: Some sources give 19 April as the start
Start day: stored as 20 April 1915. The article's siege section ('City under siege, 20 April') and the 1916 Bryce and Toynbee report ('Fighting began at Van on the 20th April') both give 20 April, as does the Near East Museum (read in the earlier pass, not reopened in this one). The article's infobox and Wikidata give 19 April, which is also the day of Djevdet's extermination order and of heavy violence elsewhere in the province, so some accounts count from there. The end is 17 May in the article body (Armenian civilian forces took control; Russian forces arrived). These English-language sources use Gregorian dates; no Old Style conversion was applied.
Ottoman authorities arrest Armenian leaders in Constantinople
War & conflictMedium confidence
Ottoman officials in Constantinople seized hundreds of Armenian leaders and intellectuals and deported them. Under Talaat Pasha's orders, an estimated 0.8 to 1.2 million Armenians were then driven toward the Syrian desert on death marches during 1915 and 1916.
Notes
Lead gives 24 April 1915 for the arrests. Wikidata gives 1915 with a start of 1915-04-24 and an end of 1923; the infobox gives the genocide as 1915-1917. Calendar not stated in source. Merged duplicate row 1915-04-24-armenian-community-leaders-are-arrested-in-constantinople (Armenian community leaders are arrested in Constantinople). Its notes: The article gives the arrest order and first wave on 24 April 1915, with the night running into 25 April. The Armenian National Archives page also dates the arrests to the night of 24/25 April and says 25 April was a Sunday, which matches the Gregorian calendar, so no Rumi conversion is needed. It says only 'several hundred' were arrested, while the article gives 235 to 270 for the first wave. Wikidata gives the year only.
Troops of the Australian and New Zealand Army Corps came ashore at night on the Aegean side of the Gallipoli peninsula, north of the intended beach. They formed a small beachhead as over two thousand were killed or wounded.
Notes
Landing on 25 April 1915 (Gregorian; British Empire sources, article dates it Sunday 25 April). The article's 'over two thousand killed or wounded' is the ANZAC total for the day and is described there as inexact. Wikidata gives an end date of 3 May; the article dates the landing itself to 25 April. The Australian War Memorial confirms the landing date and the Kum Kale diversion.
British troops land at Cape Helles on the Gallipoli peninsula
War & conflictMedium confidence
The British 29th Division came ashore at Cape Helles, the main landing area at the foot of the Gallipoli peninsula, with Royal Navy gunfire support. They gained a foothold, but their plans fell into disarray and the advance stalled.
Notes
Lead gives the landing as 25 April 1915; infobox gives 25-26 April. The Australian War Memorial confirms 25 April, five beaches, severe casualties at V and W beaches, and the foothold. The article's judgement that the commander mismanaged the landing was dropped as an opinion.
French troops landed at Kumkale, on the Asian side of the Dardanelles, to draw attention away from the main landings on the European side. They fought Ottoman forces, with an inconclusive result.
Notes
Landing on 25 April 1915 (article and infobox; the article gives the result as inconclusive). The Australian War Memorial calls the French attack at Kum Kale a minor diversionary attack on the same day, matching the row.
· Anzac Cove, Gallipoli Peninsula, Ottoman Empire · Middle East
Ottoman forces attack Anzac Cove for a second time
War & conflict
Ottoman troops attacked the British Empire forces defending Anzac Cove on the Gallipoli Peninsula over three days. The attack was repelled.
Notes
Infobox gives 27-29 April 1915; Wikidata gives 27 April only. The Australian government's Anzac portal also says Ottoman counter-attacks ran 27 to 29 April and were repulsed. The dates are Gregorian (British Empire sources).
British and French troops made the first Allied attempt to advance at Gallipoli, which came on the third day after the Cape Helles landing. Ottoman defenders beat the attack back quickly; planning was poor and communications failed.
· Mizda territory, Nafusa Mountains, Libya · Africa
Senussi forces defeat the Italians at Wadi Marsit
War & conflictMedium confidence
In the Nafusa Mountains of Libya, Senussi fighters under Ahmed al-Sunni defeated an Italian force. The result threatened Italian control of its Libyan colony.
Notes
Date: the infobox gives 7 April 1915 and the body has the Italians reaching Wadi Marsit on 6 April, camping, and being attacked in the night and following hours, which fits 7 April; an Italian specialist history (qattara.it) dates the fight only to April 1915 and does not give a day. Force sizes differ: the article says 400 Senussi against 1,400 Italians; the Italian source says about 2,000 Italians (700 regulars and 1,300 irregulars) against at least 2,000 Senussi, with 323 Italian losses and three guns and about 400 rifles captured. The row therefore gives no force sizes. The interest line uses only what the English article states (camels and baggage abandoned); the loss of guns rests on the Italian source alone and is not used.
South Africans repel a German attack at Trekkopjes
War & conflict
German forces attacked a railway station held by South African troops under Major Skinner in German South West Africa. Armoured cars helped drive the attack back.
Notes
Date 26 April 1915 is given by the article and by the South African Military History Society's account (which puts the German force at about 2,000 and Union losses at 8 killed and 34 wounded). The article's claim that this was the last German offensive of the campaign was not confirmed by that source and is left out.
British Nigerian garrison repels German attack at Gurin
War & conflict
German troops encircled and assaulted the fort at Gurin in British Nigeria, close to the Kamerun border, at first light. About forty defenders held out against several hundred attackers.
Notes
Numbers differ by source: the article says 42 defenders and 350-400 attackers; a contemporary letter by the political officer Fitzpatrick, printed in a New Zealand newspaper, says about forty soldiers and two Europeans held the fort against some 300 soldiers, 16 Europeans and four Maxim guns; both say the fort held and Pawle was killed. Exact figures are therefore left out of the row.
Real Unión was formed in Irun, in the Basque Country, by the merger of Irun Sporting Club and Racing Club de Irun. The club won the Copa del Rey in 1918, 1924 and 1927, and counts Racing's 1913 win as a fourth title.
Notes
The English article (uncited infobox and lead) gives 15 May 1915 as the founding date; Spanish Wikipedia says a joint assembly agreed the merger on 9 May 1915, and German and Spanish Wikipedia otherwise give only 1915. The days differ, so the row is stored at month level.
Shell shortage triggers a political crisis in Britain
Politics & diplomacyMedium confidence
A shortage of artillery shells at the front grew into a political crisis in the United Kingdom in May 1915. On 14 May The Times blamed a lack of high-explosive shells for the failed attack at Aubers Ridge, and within days Asquith moved to a coalition government.
Notes
The Times ran its shell story on 14 May 1915; on 17 May Asquith asked his ministers to resign and formed a coalition, and Lloyd George served as Minister of Munitions from 25 May 1915. The shortage itself dated from autumn 1914. Stored at month precision for the political crisis.
British destroyers sink two German torpedo boats off Noordhinder Bank
War & conflict
German torpedo boats sank the British trawler Columbia, then four British destroyers arrived and sank both torpedo boats.
Notes
Date 1 May 1915 and the sinking of both torpedo boats by four Harwich Force destroyers confirmed by the Wartime Memories Project entry for torpedo boat A6. The article's claims about German morale and the flotilla being too weakly armed were not confirmed outside and are left out.
Central Powers win the Battle of Dunajetz in Galicia
War & conflictLow confidence
German 11th Army under August von Mackensen, with help on the flanks from the Austro-Hungarian 3rd and 4th Armies, beat the Russian 3rd Army along the Dunajetz river. The battle was part of the Gorlice-Tarnow Offensive.
Notes
Wikidata gives 1915-05-14, imported from an older English Wikipedia revision with no other reference; the article's infobox and lead give 1-10 May 1915. Calendar not stated in source (Russian forces involved). If the source's date is Old Style (Julian), the Gregorian date would be 14 May 1915.
· Gorlice and Tarnów area, Galicia, Austria-Hungary · Europe
Gorlice–Tarnów offensive begins in Galicia
War & conflictMedium confidence
The Central Powers opened an offensive on the Eastern Front near Gorlice and Tarnów. Planned as a minor German effort to ease pressure on Austria-Hungary, it grew into their main push of 1915 and drove the Russian armies back out of Galicia.
Notes
Wikidata's start date is 2 May 1915 (unreferenced); its point-in-time value of 22 June 1915, imported from English Wikipedia, is the day Lemberg was entered. Infobox gives 2 May - 13 July 1915, while the lead says the actions went on until October, so no end date is stored.
Clara Immerwahr, a German chemist and the wife of Fritz Haber, died at Berlin-Dahlem. Her death was a suicide by gunshot.
Notes
Infobox gives Berlin-Dahlem, Kingdom of Prussia, German Empire. The German Chemical Society (GDCh) biography confirms death on 2 May 1915 by shooting herself with her husband's service pistol, in the garden of the family villa (the family had moved to Dahlem in 1910; the page does not name Dahlem for the address), and notes a Breslau newspaper called her 'our first female doctor' after her 1900 promotion. The article's wording 'first German woman' to earn a chemistry doctorate was softened because the GDCh page notes an earlier woman chemist with a German doctorate (Göttingen, 1874).

Sport
Athletic Bilbao defeated RCD Español 5-0 in the 15th Copa del Rey final, played at the Estadio de Amute in Irun. Pichichi scored three goals for the winners.
RAF Northolt opens as a Royal Flying Corps aerodrome
War & conflictMedium confidence
The aerodrome in Ruislip opened on 3 May 1915 for the Royal Flying Corps, first as RFC Military School, Ruislip. No. 4 Reserve Aeroplane Squadron moved there from Farnborough.
Notes
Opening on 3 May 1915 is given by the article body and by the Four Prop's RAF Northolt history (RFC Military School, Ruislip, No. 4 Reserve Aeroplane Squadron); the article's lead says only 'May 1915'. The UK Airfield Guide says No. 4 Reserve Aeroplane Squadron moved in from Farnborough on 3 March 1915, which looks like a slip but is a disagreement, so confidence is medium. The article's 'oldest RAF base' claim was not found in either outside source and is left out.
· Celtic Sea, near Old Head of Kinsale, Ireland · Europe
RMS Lusitania is torpedoed and sunk off Ireland
War & conflict
A German U-boat torpedoed the British liner Lusitania near the Old Head of Kinsale, and she sank in 18 minutes. Of 1,960 people aboard, 1,197 were killed, among them about 128 Americans.
Notes
Casualty figures differ slightly by source: the article says 1,197 of 1,960 aboard died, about 128 of them Americans; a news summary gives 1,198 of 1,959 and 128 Americans. Both agree on the 18 minutes to sink and the date 7 May 1915.
Danes elected a new Folketing so that the constitution could be revised. Because of the war there was no campaigning, and 104 of the 114 seats were uncontested.
Notes
Statistics Denmark's official report on the election (opened) and the infobox give 7 May 1915; the lead says 6 May. Voting in the Faroe Islands was on 12 May, which is the other Wikidata date.
The French opened an offensive in Artois aiming to capture Vimy Ridge and cut German rail supply lines, with British attacks alongside. It ran to 18 June and cost the French 102,500 casualties.

The Times prints a report headed "Torture of a Canadian Officer"
War & conflictMedium confidence
The Times printed a short item, credited to its Paris correspondent, about the torture of a Canadian officer. It belongs to the story of a crucified Allied soldier on the Western Front, a tale later largely dismissed as an urban legend or propaganda.
Notes
Date is that of the Times item. The alleged incident is placed near Ypres on or around 24 April 1915, with contradictory accounts; no body was recovered.
· Konary, Congress Poland, Russian Empire · Europe
Battle of Konary begins as Russian 4th Army counter-attacks
War & conflictMedium confidence
The Russian 4th Army launched a counter-offensive in the Kingdom of Poland, aimed at the Central Powers. Pilsudski's Polish 1st Brigade held out near Konary and Klimontow until the offensive was repelled on 23 June.
Notes
English article: battle from 16 May to 23 June 1915. Polish Wikipedia also starts it on 16 May 1915 (Austro-Hungarian and Legion sources, so Gregorian) and says the heaviest fighting ran 16-25 May, followed by trench warfare to 23 June. Wikidata has 16 May unsourced.
· Quintinshill, near Gretna Green, Scotland · Europe
Quintinshill rail disaster kills over 200 near Gretna Green
Disasters
A troop train carrying soldiers bound for Gallipoli ran into a stationary local train near the Quintinshill signal box, and a northbound sleeping-car express then hit the wreckage. Fire spread to all five trains. The official death toll was 227, most of them Royal Scots Territorials.
Notes
Collision at 6:49 am. Official toll 227 (215 soldiers, nine other passengers, three railway employees); the Army later reduced its 215 figure by one.
Futurist-linked journal Lacerba ceases publication in Florence
Art & literature
Lacerba, a Florence-based Italian literary journal closely linked to the Futurist movement, published its last issue. It had begun on 1 January 1913 and stopped two days before Italy entered the war.
Fighting begins on the Italian front between Italy and Austria-Hungary
War & conflictMedium confidence
Italy, once allied with Austria-Hungary, entered the war on the Entente side and began fighting along the Austro-Hungarian border. The front settled into trench warfare, with fighting at high altitude, and lasted until November 1918.
Notes
The infobox gives 24 May 1915 - 4 November 1918. Wikidata gives an unreferenced start of 23 May 1915, the day the article's timeline gives for Italy's declaration of war on Austria-Hungary.
Austro-Hungarian fleet bombards Ancona after Italy enters the war
War & conflict
After Italy declared war on 23 May, the Austro-Hungarian navy attacked military and civilian targets in Ancona and nearby communities. 63 people died in Ancona alone.
Notes
The infobox gives 23-24 May 1915, but the raid itself is described on 24 May (Italy declared war on 23 May); another English Wikipedia article, SMS Erzherzog Friedrich, dates the bombardment to 24 May. The article's statement that the fleet left Pola on 24 May was left out of the summary because it conflicts with a dawn attack that day.
The name White War covers the high-altitude fighting of the Italian front, mainly in the Dolomites and the Ortles-Cevedale and Adamello-Presanella Alps. The historian Heinz Lichem von Löwenbourg judged that about two thirds of the dead on the mountain front died from avalanches, frostbite and exhaustion rather than combat.
Notes
Infobox gives May 24, 1915 to November 4, 1918. The infobox total of 150,000 to 180,000 deaths is not supported in the article text, so it is not used; the two-thirds figure is a rough rule quoted from Löwenbourg in the article and in Italian and German Wikipedia.
Italian and Austro-Hungarian soldiers fought a long series of clashes on the flat summit of Monte Piana between 1915 and 1917. The Austrians kept the dominant positions throughout.
Notes
Infobox gives 24 May 1915 to 22 October 1917; the first Italian deaths on this front came on 24 May and the first Austrian attack on the summit on 7 June 1915. The infobox figure of 14,000 killed is not supported anywhere in the article text or in Italian Wikipedia, so it is not used.
Britain, France and Russia condemn the Armenian genocide
Politics & diplomacy
On Russia's initiative, three Entente powers (Russia, France and the United Kingdom) put out a declaration condemning the Armenian genocide being carried out inside the Ottoman Empire, warning that those responsible would be held to account.
Notes
Date is New Style: the New York Times carried the declaration on its front page on 24 May 1915 and the US State Department received an official copy on 28 May, which fit only a New Style 24 May. Wikidata also gives 1915-05-24.
· Near Bolimów, Congress Poland, Russian Empire · Europe
The Second Battle of Bolimów begins
War & conflictMedium confidence
German troops released poison gas against Russian positions near Bolimów in Poland. The gas caused heavy Russian losses, but the German push toward Warsaw was halted. The battle lasted to 7 July 1915.
Notes
Infobox gives 31 May - 7 July 1915; the body describes the first gas attack on 31 May and the third battle on 6-7 July. Wikidata gives an unreferenced start of 31 July 1915, after its own end date of 7 July. The January 1915 date the detector found refers to when the Bolimów sector formed (December 1914 - January 1915), not to this battle.

SportMedium confidence
The second Far Eastern Games began in Shanghai on 15 May 1915, at Hongkou Park. The event took its Championship Games name that year, and cycling appeared only in this edition.
Notes
Start date 15 May is given by the English article for the Games, its editions table and its dedicated 1915 article. The last day is disputed inside English Wikipedia: the editions table and the 1915 infobox say 21 May, the 1915 article lead says 22 May; neither is clearly better, so no end date is stored. Wikidata gives only the years of the series.
Riots between Sinhalese Buddhists and Ceylon Moors begin in Kandy
Politics & diplomacy
Ethnic riots began in Kandy on the night of 28 May, reached neighbouring villages on 30 May, then Colombo on 31 May. British authorities declared martial law from 2 June and put down the riots, using summary executions.
Notes
End date varies: infobox gives 8 August 1915; lead says suppressed by 9 June; Wikidata gives end 1915-08-30 (end of martial law). A Sri Lankan newspaper history (Sunday Times) says the violence began in the early hours of 28 May, the Vesak procession day, and martial law was declared on 2 June.

Second Battle of Krithia begins at Gallipoli
War & conflict
Allied forces again tried to advance at Helles toward Krithia and Achi Baba. After three days of costly fighting they gained only a small amount of ground and missed their objectives.
Notes
Dates 6-8 May 1915 given by the article's infobox and by Wikidata; the earlier check also cited the Australian War Memorial's London page (not re-opened in this repair). The article's Allied casualty figure of 6,500 (and 2,000 Ottoman) rests on one source and was not confirmed, so it is not used. The 2nd Brigade's loss is stated differently inside Wikipedia: the Krithia article says 50% casualties, the 2nd Brigade article says roughly a third of its strength; the interest line uses the lower, 'roughly a third'. An earlier version of this row gave about 1,000 killed and wounded in an hour, which could not be confirmed from the approved sites. Dates are Gregorian.
Russian battleships and Ottoman battlecruiser Yavuz Sultan Selim clash north of the Bosporus
War & conflictMedium confidence
A Russian squadron of pre-dreadnought battleships faced the Yavuz Sultan Selim, an Ottoman battlecruiser, out on the Black Sea above the Bosporus. The Ottoman ship pulled back after a short firefight, and the Russian shelling operation was interrupted.
Notes
Also called the Battle of the Bosporus. Polish Wikipedia gives the date as 10 May 1915 with 27 April as the Old Style equivalent, so the stored date is already Gregorian (New Style); the English article also gives 10 May. Calendar not stated in the English article. Region left as Middle East because the action took place 22-25 miles north of the Bosporus.

About 42,000 Ottoman troops attacked the 17,300 ANZAC defenders at Anzac Cove in the early hours of 19 May. The assault had failed by midday, costing the attackers thousands of casualties against fewer than seven hundred for the defenders.
Notes
Ottoman casualty figures are uncertain: the Wikipedia article says around ten thousand including three thousand dead, while the Australian Government Anzac Portal says about 3,000 dead and 10,000 wounded. Defender losses: 168 dead and 468 wounded (Wikipedia), 160 killed and 468 wounded (Anzac Portal). Wikipedia lists truces on 20 and 24 May; the Anzac Portal names only 24 May. Dates are the Gregorian dates of the Allied sources.

New Zealand Mounted Rifles troops captured a new Turkish position on the northern edge of the ANZAC beach-head and named it No.3 Post. Cut off and counter-attacked, the 9th Squadron held on for twenty-eight hours before relief, and the post was then abandoned.
Notes
Calendar not stated in the article; Ottoman Empire, but the dates are the Gregorian dates used by New Zealand sources. The New Zealand History site (Ministry for Culture and Heritage) also dates the action 28 to 30 May 1915 (and says the post was abandoned on 31 May; the article says the same night as the relief).

War & conflict
From 31 May to 3 June 1915, British forces under Charles Townshend fought Ottoman troops in the flooded marshes of the Tigris between Qurna and Amara. The British took Amara, and 1,773 Ottoman troops were captured.
Notes
Infobox and lead give 31 May - 3 June 1915. Wikidata's point in time of 3 June 1915 is the battle's last day; its start (31 May) and end (3 June) match the article. Also called the Second Battle of Qurna.
British and French forces began an attempt to take Jaunde, the German capital in Kamerun. Poor coordination, hard terrain, bad weather and strong German resistance forced a retreat in late June.
Notes
Infobox gives 1 May to late June 1915 and Wikidata gives 1 May as the start and June 1915 as the end; the article has no body text beyond the lead. Omniatlas's map notes date the first attack to May-June 1915, with the Allied columns beaten back in late June, and a second assault from October. No outside source confirms 1 May, so the dates are kept at month level.

Notes
The English article says this was the first referendum passed in every canton; Swissvotes (the Swiss referendum database) confirms the date, 22 yes and 0 no cantonal votes and 94.27 per cent yes, but not that it was the first such result, so that claim is not used.

Lead places it overnight between 6 and 7 June; infobox and body give 7 June 1915.
Austro-Hungarian seaplane shoots down Italian airship Città di Ferrara
War & conflictMedium confidence
After a bombing raid on Fiume, the Italian navy airship M.2 Città di Ferrara was pursued by an Austro-Hungarian air and naval patrol. The crew of an L48 seaplane destroyed it in the air; two of its crew died and the survivors were taken prisoner.
Notes
Infobox gives the location as about 20 km from "Premura, Vis Island", but the article body says about 20 km from Premuda, an island of the Zadar Archipelago north-west of Zadar (Croatia), not near Vis; the lead says near the coast of north-eastern Italy. Place is therefore given only as the Adriatic Sea. The article is tagged as relying on self-published sources; date 8 June 1915 agrees with Wikidata.
On the evening of 9 June 1915, two battalions of Italy's Ravenna Brigade crossed the Isonzo on a pontoon bridge, set up a bridgehead on the east bank and began climbing the hill. The struggle with Austria-Hungary over it lasted until May 1917.
Notes
Lead gives June 1915 to May 1917; infobox gives 9 June 1915 to 14 May 1917. The hill fell to the Italians at the start of the Tenth Battle of the Isonzo (began 12 May 1917); the exact end day appears only in the infobox, so the end is stored at month level. Italian Wikipedia confirms the evening of 9 June 1915 crossing by two Ravenna Brigade battalions.
Venizelos's Liberal Party wins the Greek parliamentary election
Politics & diplomacy
In this Greek parliamentary election, Eleftherios Venizelos's Liberal Party won a landslide, taking 187 of the 316 seats. Venizelos said the result proved Greeks backed his policy of favouring the Allies.
Notes
Election date from the full article, written with its Gregorian-to-Julian template: 13 June 1915 N.S. (31 May 1915 O.S., hence the name 'May 1915' election). Wikidata also gives 13 June 1915.

Polish uhlans charge Russian positions at Rokytne
War & conflict
Polish Legions cavalry from the 2nd Brigade, fighting for Austria-Hungary, attacked Russian positions near Rokytne under Rittmeister Zbigniew Dunin-Wasowicz. About 70 uhlans took part and 17 were killed.
Notes
Date is the Gregorian date: the Tomb of the Unknown Soldier in Warsaw names the charge "ROKITNA 13 VI 1915" and Polish Wikipedia gives 13 June 1915 (Austro-Hungarian side). Lead gives 70 uhlans, 17 killed and 23 wounded; infobox gives 73 uhlans, 17 killed, 22 wounded and 8 captured; the summary uses only the figures that agree (about 70, 17 killed).
Portuguese voters chose a new parliament. The Democratic Party took 106 of the 163 Chamber seats and 45 of the 69 Senate seats, and its leader Afonso Costa became Prime Minister after the vote.
Battles of the Isonzo begin between Italy and Austria-Hungary
War & conflictMedium confidence
Italy and Austria-Hungary fought a series of twelve battles along the Isonzo river valley between 1915 and 1917. The area was the only practical one for Italian operations.
Notes
Start taken as the opening of the First Battle of the Isonzo, 23 June 1915 (the article's list and table, its lead's 'June 1915', and the First Battle of the Isonzo article). The infobox dates the front as a whole from 24 May 1915, Italy having entered the war on 23 May; Wikidata's 23 May has no reference.
Italy attacked Austria-Hungary along the Soča (Isonzo) river, hoping to push the Austrians back and take Trieste. Heavy fighting centred on Gorizia, and the Italians ended with only small gains.

Armenian militia resists Ottoman troops at Shabin-Karahisar
War & conflictMedium confidence
Armenian militia of the Hunchaks from Giresun Province held a fort outside the town of Shabin-Karahisar against Ottoman troops during the Armenian genocide in June 1915.
Notes
English Wikipedia (infobox, lead and Wikidata) gives 2-30 June 1915, about 250 Armenian fighters and a month of resistance. A blog that quotes Ottoman military reports gives a start on 5 June, about 500 attackers and a rebellion suppressed by the 18-19 June reports. The sources disagree on days, length and numbers and none is clearly better, so the row is stored at month level without a count. Calendar of the sources not stated (Ottoman Empire).
The Battle of Kanzan between the Al Saud and the Ajman begins
War & conflictMedium confidence
In June 1915 Abdulaziz led an army of 4,000 men against the Ajman tribe, which numbered fewer than 3,000, at Kanzan in Al Ahsa. The Ajman were resisting Al Saud rule.
Notes
English Wikipedia says the fighting began in June 1915 and lasted nearly six months, with an Ajman victory. Arabic Wikipedia dates the battle to 15 Sha'ban 1333 AH (28 or 29 June 1915) and says the Ajman fled, so the length and outcome are disputed and left out of the row. Wikidata gives an end date of November 1916 (month level).
The Ottoman government enacts the Temporary Law of Deportation
Politics & diplomacy
The Ottoman government officially enacted the Temporary Law of Deportation, which authorised the deportation of the Empire's Armenian population. The Council of Ministers had passed it on 27 May 1915, and it expired on 8 February 1916.
Notes
Passed by the Council of Ministers on 27 May 1915; officially enacted 1 June 1915 (used here, same as Wikidata); German Wikipedia gives the same dates, with 1 June as the day it took force on publication in the Takvim-i Vekayi (18 May 1331 in the Rumi calendar) and validity until 8 February 1916. The article also records a repeal order of 21 February 1916.

British and Indian forces under George Gorringe attacked the Ottoman garrison of Nasiriyah in Mesopotamia and defeated it. Each side fielded roughly 5,000 men.
Notes
Wikidata gives 1915-07-25, the end of the battle; the infobox gives 27 June - 25 July 1915 while the lead places the battle in July 1915. Infobox Ottoman losses: 2,000 killed or wounded, 1,000 taken prisoner. calendar not stated in source.
· Cape Helles, Gallipoli peninsula, Ottoman Empire · Middle East
Battle of Gully Ravine begins at Cape Helles
War & conflictMedium confidence
British and Indian troops attacked Ottoman positions along Gully Ravine at Cape Helles on the Gallipoli peninsula. Unlike earlier Allied attacks there, this one largely reached its aims, though at a heavy cost; Ottoman casualties from 28 June to 5 July are estimated at 14,000 to 16,000.
Notes
The infobox figures of 3,800 Allied and 6,000 Ottoman casualties are not used: the article body puts Ottoman casualties for 28 June to 5 July at 14,000-16,000 (the 6,000 refers to those under the earlier bombardment of the French attack), and Turkish Wikipedia gives 16,000. The 2,500 French casualties in the article belong to the separate French attack on Kereves Spur on 21 June, a week earlier, so they are not counted here; Gully Ravine itself was a British and Indian attack on the left flank (29th Division, 29th Indian Brigade, 156th Brigade). Calendar not stated in the article (Ottoman Empire); the dates are the Allied Gregorian dates.
In early June 1915 about 600 rebels under a local prince, Sabukki, took over Bussa, in protest at indirect rule after the British deposed the Emir, Kitoro Gani. They killed roughly half of the Native Administration set up three months before, and a small British force soon ended the rising.
Notes
Candidate region Europe corrected to Africa (Bussa is in Nigeria). Article places the start in early June 1915.
A national football championship was launched in the Sultanate of Morocco on 11 June 1915 under the rule of the USFSA. It is the forerunner of today's Botola Pro, the top tier of Moroccan football.
Notes
Infobox lists founding under the USFSA in 1915, the LMFA in 1922 and the FRMF in 1956. RSSSF lists the first official USFSA championship of Morocco, 1915/16, as starting on 11 June (year implied by the 1915/16 season). The 22 titles for Wydad AC match French Wikipedia's table.
A British force launched an amphibious raid from Kisumu against Bukoba in German East Africa, aiming to destroy its wireless station. The fighting lasted until 23 June and ended in a British victory.
A Central Powers offensive, led mainly by the German army, aimed to defeat Russian forces in southern Poland and Galicia. It ran until 28 August 1915 and ended in a Central Powers victory.
Notes
Start day disputed, so stored at month level: the English lead, body and Wikidata give 13 July 1915 (Linsingen's Army of the Bug taking Starogrod), the English infobox gives 14 July, and German Wikipedia (Bug-Offensive) has Mackensen's armies attacking from 15 July after the Narew offensive began on 13 July. End 28 August 1915 per the English infobox, lead and Wikidata; German Wikipedia says only that the advance was halted at the end of August. The English article's outcome section says the Central Powers failed to achieve a deep breakthrough. The article appears based on Russian sources, so some dates may be Old Style.
The Vorticist magazine Blast, written mainly by Wyndham Lewis, brought out its second edition in July 1915, a year after the first. Only two editions were ever published.
Notes
The lead gives 15 July 1915 for the second edition; the Editions section gives 20 July 1915. Wikidata holds only 1915 for the end date, unsourced. No outside source could be checked (web search unavailable), so the shared month is stored. Infobox final date: 1915.
A football club in Beggen, Luxembourg, was founded on 1 July 1915. It later became FC Avenir Beggen, six-time champion of Luxembourg.
Notes
German Wikipedia says 1 July 1915 is regarded as the founding date. The original name is disputed: English and French Wikipedia say FC Daring Beggen, renamed Avenir Beggen in 1916, while German Wikipedia says the original name was Etoile Sportive, changed because another club had that name. All three agree on SV 1915 Beggen in 1940-44 and FC Avenir Beggen again from 1944.

Notes
Full article dates the battle 2 July 1915 N.S. with its Gregorian-to-Julian template (Old Style 19 June 1915) in the infobox and battle section; the excerpt's lead says only July 1915. Wikidata also gives 2 July 1915, but labels it Battle of Åland Islands with place Åland; the article is titled Battle of Gotland and places the fighting off Gotland. Infobox result: Anglo-Russian victory; German side 27 dead and 49 wounded.

The Czech composer Leoš Janáček completed a first version of his orchestral rhapsody Taras Bulba, based on Gogol's novel. He revised it heavily afterwards, and the work reached its first performance in Brno in 1921.
Notes
Wikidata also gives 29 March 1918, the date of the second, almost complete version. First performed in Brno on 9 October 1921 (French Wikipedia agrees). A Musicologica Brunensia article says the work was completed by the beginning of July 1915, consistent with the 2 July date.

The Georgian poet and writer Vazha-Pshavela, pen name of Luka Razikashvili, died in Tbilisi (then called Tiflis). He was laid to rest in Georgia's old capital.
Notes
10 July 1915 is New Style: Caucasian Knot gives 'June 27 (July 10), 1915', and Wikidata cites the Great Russian Encyclopedia for 27 June 1915 (Julian). The article's infobox and text give 10 July.

German forces under Gallwitz's army group and the 8th Army attacked from southern East Prussia across the Narew River against the Russian fortress line there. The article describes the operation as a German victory that broke through four fortified positions.
Notes
Start 13 July 1915 is given by the English article, Wikidata and German Wikipedia (Narew-Offensive). The end is disputed: the English lead and infobox give 27 August 1915, while German Wikipedia and Wikidata give 24 August, so it is stored at month level. Russian Wikipedia dates the Narew battle 10 (23) July to 20 July (2 August) 1915, a shorter span. Figures in the English lead (215,000 prisoners, 300 km advance, about 30,000 German dead and missing) were not confirmed by an outside source, so the summary no longer uses them.

Alberta voters approved a proposed Liquor Act in a plebiscite, 58,295 to 37,509. Prohibition took effect on 1 July 1916, eleven months after the vote.
Notes
The lead text gives June 21, 1915, but the infobox, the body (referendum date set for July 21, 1915) and Wikidata give 21 July 1915. The infobox total (95,554) differs from the results table (95,804, the sum of 58,295 and 37,509); the table is used. Vote totals come from the English article only; no outside check available. The article's lead claim that this was the first plebiscite asking Alberta voters to decide a public issue was not confirmed outside, so it is not used.

Olaria Atlético Clube is founded in Rio de Janeiro
Sport
Olaria Atlético Clube was founded in the Olaria district of Rio de Janeiro. It now plays in the Campeonato Carioca Série A2.
Notes
Both English and Portuguese Wikipedia give 1 July 1915. The first name differs: English says Japonês Futebol Clube, renamed Olaria Atlético Clube later that year; Portuguese says it was founded as Olaria Futebol Clube at the home of Captain Alfredo de Oliveira. The name is therefore left out of the summary.
Tapani Incident uprising against Japanese rule begins in Taiwan
War & conflictMedium confidence
Han Chinese and Indigenous Taiwanese fighters, including Taivoan, rose against Japanese rule, starting at the Xilai Temple in Tainan. Under leaders such as Yu Qingfang and Jiang Ding they stormed several police stations; Japan prevailed.
Notes
Infobox dates: 6 July 1915 to 18 May 1916. German Wikipedia also gives 6 July 1915 for the first attacks, so the start is supported. The end is disputed, so only the year is stored: English Wikipedia's body has Jiang Ding surrendering in April 1916 and his followers arrested on 18 May 1916, while German Wikipedia says the uprising ended with his arrest on 16 April 1916 (Polish Wikipedia says April 1916). Also called the Xilai Temple Incident and the Yu Qingfang Incident. The English body places the first police-station raids in August 1915 (Yu Qingfang was betrayed and handed over on 22 August 1915), which differs from the infobox start.
Yaskawa Electric, now a Japanese maker of servos, motion controllers, AC motor drives and industrial robots, is founded by Daigoro Yasukawa with money from his father, the coal-mining industrialist Keiichiro Yasukawa.
Notes
Day 16 July 1915 from the English and Japanese Wikipedia infoboxes; the English lead and Wikidata give only 1915, and the company's milestones page gives the year. Founder: English Wikipedia names Keiichiro Yasukawa; the company's milestones page calls Keiichiro the founding promoter and his fifth son Daigoro the founder; Japanese Wikipedia also calls Keiichiro the founding promoter. Legal form differs: the company page says a joint-stock company in 1915, Japanese Wikipedia a limited partnership (gōshi kaisha) in 1915 that became a joint-stock company in 1919. The milestones page is the company's own account.
Home Minister Ōura Kanetake resigns in the Ōura scandal
Politics & diplomacyMedium confidence
Ōura Kanetake was forced to resign as Home Minister after charges that party funds were given to a Diet official to sway votes on a military spending bill. He was not indicted.
Notes
Kind is end, but no end date for the scandal is stated; the row uses Ōura's forced resignation on 29 July 1915 (English Wikipedia; Japanese Wikipedia's Second Ōkuma Cabinet article also says he resigned on 29 July, while its minister table and the Ōura scandal article give 30 July for the formal dismissal / resignation letter in the official gazette). Wikidata gives only the year 1915 as the end. English Wikipedia says the cabinet held a mass resignation in October 1915; Japanese Wikipedia contradicts this: the cabinet tendered resignations the day after Ōura left, the Emperor refused them, a reshuffle took place on 10 August 1915, and Ōkuma resigned on 4 October 1916 (successor cabinet 9 October 1916). The Japanese account is better detailed and is used. The 29 July date rests on English and French Wikipedia (French closely follows the English).

When Ottoman deportation orders reached six Armenian villages near Musa Dagh in July 1915, the villagers refused to go and withdrew onto the mountain. They held off assaults for fifty-three days, and the French Navy eventually rescued them.
Notes
Start day disputed, so stored at month level. The English infobox gives 21 July to 12 September 1915 and Russian Wikipedia says the 8-day deadline to leave expired on 21 July and counts 53 days to the evacuation on 12 September, but French Wikipedia says the villagers began climbing Musa Dagh on 31 July and reached the top on 2 August, after the deportation order was posted on 30 July.

War & conflictLow confidence
Russian troops attacked the fortifications of Bitlis in July 1915 without success. A Russian corps including Armenian volunteer units took the town in March 1916; the Ottomans won it back in August, but Russian forces recaptured it later that month.
Notes
Infobox gives July 1915 - August 1916; the lead describes the battle as engagements of summer 1916, with the first confrontation in July 1915. The July 1915 failed assault is stated only in the English article; French Wikipedia's account of the battle begins on 21 February 1916 and does not mention it, and no outside source for it was found. Wikidata end date is 1 August 1916. The Russians took Bitlis on 2-3 March 1916 (French Wikipedia agrees) and recaptured Mush and Bitlis on 24 August 1916 after the Ottoman retaking.

War & conflictMedium confidence
Assyrian villagers and refugees defended Iwardo in Tur Abdin against Ottoman authorities and allied Kurdish tribes during the Assyrian genocide. Estimates put the defenders at 700 to 1,000 fighters against 13,000, and the defence ended in an Assyrian victory.
Notes
The infobox gives July - October 1915, but the article body says Kurdish and Ottoman forces began arriving in mid-July and the defenders resisted for 52 days (Dutch Wikipedia also says 52 days), which would end around early September. The end is therefore uncertain and not stored. Calendar not stated in the article (Ottoman Empire).
Russian and Ottoman forces fight the Battle of Manzikert
War & conflictLow confidence
A Russian general launched an offensive near Malazgirt on 10 July 1915, and fighting lasted until 26 July. Both armies suffered heavily. The Russians pulled back northward and Turkish troops took Malazgirt again.
Notes
Calendar not stated in source (Russian and Ottoman forces involved). Infobox location: Malazgirt, Bitlis Vilayet. If the source's date is Old Style (Julian), the Gregorian date would be 23 July 1915. French and Turkish Wikipedia repeat the same 10-26 July dates, so they are not independent. Outcome is also described differently: the English article and infobox say Ottoman victory, while Russian Wikipedia says the situation changed little and the Russians gained a slight tactical advantage.

The German campaign in Angola ends
War & conflictMedium confidence
German and Portuguese troops had clashed on the border of southern Portuguese Angola since October 1914, before the two countries were formally at war. The campaign ended in a Portuguese victory.
Notes
Disputed end date. English Wikipedia's infobox gives 9 July 1915 for the end of the campaign (the day South West Africa surrendered), its body says Portuguese forces reoccupied Humbe on 7 July, and Italian Wikipedia says 17 July 1915. Stored at month level. Wikidata gives 9 July 1915 without a reference. Italian Wikipedia adds that the Germans kept arming local revolts in the area until at least September 1915.

South African forces captured the German colony during the South West Africa campaign of the First World War. The territory then stayed under South African administration until 1990.
Notes
The article's infobox gives the start of the South African occupation as 9 July 1915, the date the German forces' surrender was signed (German Wikipedia: 9 July 1915, Governor Seitz and Lt Col Franke; military administration followed). The same infobox's status line oddly dates the occupation 1916-1920, and the League of Nations mandate began in 1919/1920. The day stored is the surrender and start of occupation.

John Leopold Brodie patents a steel combat helmet in London
TechnologyMedium confidence
Riga-born inventor John Leopold Brodie designed and patented a steel combat helmet in London. A modified version became Britain's Helmet, Steel, Mark I and the M1917 helmet in the United States.
Notes
Lead says designed and patented in 1915; a body sentence places the patent in August 1915. The August month rests on the English article alone: German and French Wikipedia say only 1915. German Wikipedia also says the Mark I first reached the front in notable numbers in November 1915. The English lead calls Brodie a Latvian inventor while German Wikipedia calls him British; the English body says he was born in Riga and working in London, so the summary uses 'Riga-born'. The claim of a million helmets produced by summer 1916 was not confirmed outside and is not used.
· Volhynia and Eastern Galicia (present-day Ukraine) · Europe
Rovno offensive begins
War & conflictMedium confidence
Austro-Hungarian armies, backed by German troops, pushed from Eastern Galicia into Volhynia against Russia's Southwestern Front with Rovno as their goal. They took Lutsk and Dubno but never reached Rovno; Russian counter-attacks inflicted heavy losses, and part of Eastern Galicia stayed in Russian hands.
Notes
Start dates differ: English Wikipedia's infobox gives 27 August 1915 (its text has Kovel taken on 25 August and fighting on 26-27 August); German Wikipedia says the Austro-Hungarian advance began on 26 August; Russian Wikipedia gives 19 August (6 August Old Style). Wikidata gives 27 August with no reference. All agree on August 1915, so the month is stored. End dates differ too: 15 October (English infobox and Wikidata), 20 September (7 September Old Style, Russian Wikipedia), late September (German Wikipedia), so no end date is stored. The day dates in the English text follow the Austrian official history and are Gregorian. Outcome wording also differs: the English infobox calls it a Russian victory; Russian Wikipedia says Russian troops fell back 30-150 km but Rovno was not taken; German Wikipedia says the Central Powers gained ground up to the Styr at heavy cost. Rovno was the objective; fighting took place in Volhynia and Eastern Galicia.
German forces under Karl Litzmann besieged the Russian fortress at Kaunas, held by a garrison of 66,629 men under Vladimir Grigoriev. The Germans, with four divisions, took it on 18 August.
Notes
Start date disputed within Wikipedia: the siege article gives 12-18 August 1915 (infobox adds the Julian equivalent, 30 July-5 August), but its body says the Germans intensified their bombardment on 8 August, and the Kaunas Fortress article says the fortress withstood eleven days of assault before capture (about 8-18 August). Stored at month level; both give 18 August for the fall. Dates are Gregorian.
· Osowiec Fortress, Congress Poland, Russian Empire · Europe
The Attack of the Dead Men at Osowiec Fortress
War & conflictMedium confidence
After German artillery fired poison gas at Osowiec Fortress, the surviving Russian soldiers, with cloths over their faces, counterattacked and routed the German troops. Almost the whole garrison was affected by the gas.
Notes
German and Polish Wikipedia both date the attack to 6 August 1915 (German: gas attack from 4 am), so the date is supported; the Russian evacuation followed on 18 August 1915. Polish Wikipedia calls 'Attack of the Dead Men' a journalistic term used in Russian and sometimes Polish writing for the counterattack of one company of the 226th Zemlyansky regiment. The English infobox's figure of about 800 Russian gas deaths was not confirmed outside (Polish Wikipedia says over 1,600 soldiers were put out of action and nearly the whole garrison poisoned), so it is not used. Calendar not stated in the English source.
A German High Seas Fleet force set out to wipe out Russia's naval forces in the Gulf of Riga, ahead of a planned troop landing to help take Riga. It cleared the minefields and entered the gulf on 19 August, but failed in its aim and withdrew.
Notes
Infobox gives 8-20 August 1915. Wikidata gives start 8 August and end 19 August (both unreferenced) and a single point in time of 20 August (imported from English Wikipedia). The text has the first attempt on 8 August, the flotilla entering the gulf on 19 August and a failed landing at Pernau on 20 August. The article's day dates are New Style: captions pair 3 (16) - 8 (21) August and 4 (17) August as O.S. (N.S.), matching the text's second attempt on 16 August and action on 17 August.
· Novogeorgievsk, Russian Empire (now in Poland) · Europe
Siege of Novogeorgievsk begins
War & conflictMedium confidence
German forces under Hans Hartwig von Beseler besieged the Russian fortress of Novogeorgievsk after the Bug-Narew offensive broke Russian defences. The fortress, under Nikolai Bobyr, fell and its entire garrison was captured.
Notes
calendar not stated in source. Body: fortress surrounded on 10 August, bombardment a few days later, surrender negotiated early on 20 August; infobox gives 10-20 August 1915 and French Wikipedia gives the same dates. Start date is the encirclement.
Hammarby IF, a Stockholm sports club, officially set up a football department after accepting an offer from Klara SK. The Hammarby IP sports ground in Södermalm was also built that year.

Notes
29 August 1915 per the article and the Neue Deutsche Biographie (vol. 20, 2001: died 29.8.1915 Veldes); Wikidata also cites the Czech national authority file for 29 August. Wikidata's preferred value is 30 August (citing GND and one other database) and it also lists 19 August (citing a single Google Books page). 29 August kept as best supported.

Hurricane makes landfall in Texas southwest of Galveston
DisastersMedium confidence
A Category 4 Atlantic hurricane came ashore at San Luis Pass, southwest of Galveston, early on 17 August. Across its whole path it killed 403-405 people and caused at least $30 million in damage; Galveston's new seawall helped protect the city.
Notes
Date is the landfall. The storm formed near Cabo Verde on 5 August; Wikidata gives 5 August to 23 August; extratropical 20 August. Damage figures vary (an early estimate was $50 million).
Carlos Finlay, a Cuban epidemiologist, died at home in Havana after a stroke. He is recognised as a pioneer in yellow fever research.
Notes
The article's lead, infobox and text give 20 August 1915 (died at his house in Havana after a stroke), and the BnF authority record gives 1915-08-20. Wikidata also lists 19 August 1915, attributed to BnF, SNAC, Find a Grave and Britannica, but the current BnF record says 20 August. The article's short description reads 1833-1914, which conflicts with the rest of the article.

Notes
Row is the formal opening (August 1915 in the article); the building was completed in April 1915. Wikidata gives opening 5 August 1915 and inception 5 April 1915, both unsourced, so the month is stored.

Also known as the August Offensive, this British operation aimed to take the Sari Bair ridge, the high ground in the middle of the Gallipoli peninsula, alongside a new landing at Suvla Bay. It lasted until 21 August 1915 and ended in an Ottoman victory.
The British meant this as a minor action at Helles to divert attention from the coming August Offensive. Brigadier General H.E. Street instead ordered a series of costly attacks that gained only a small patch of ground, the Vineyard.

Allied forces attacked the Ottoman-held peak of Chunuk Bair in the Sari Bair range. New Zealand and British troops reached the summit on 8 August, but the relieving British battalions were forced from it on 10 August when Mustafa Kemal led an Ottoman counter-attack.
Notes
calendar not stated in source. Infobox gives 7-19 August; the body says British units reached the summit early on 8 August and were driven off on 10 August, and describes the peak as retaken "a few days later"; no body statement supports 19 August, so no end date is stored. No outside check available for the end date.
A British expeditionary force, mostly Indian Army troops, entered Bushehr by land and sea with naval gunfire support and proclaimed the city occupied. Iran had declared neutrality in the war.

Gallipoli was Ottoman territory, but this is the date recorded for a soldier of the British Empire forces, so no calendar shift applies; matches Wikidata.
Assyrian defenders, with a few Armenians, held out at Azakh against Ottoman forces and Kurdish tribes during the Assyrian genocide. About 1,200 Christians were killed in the siege, and the attackers eventually withdrew.
Notes
calendar not stated in source. Infobox gives August 18 - November 21, 1915, but the 21 November end date is uncited and the Sayfo article says the defenders repelled attacks over about three weeks after the first attack on 17 or 18 August, so no end date is stored.
British forces attacked at Suvla on Scimitar Hill, aiming to remove the Ottoman threat and link up with the Anzac sectors. The assault failed after heavy fighting that lasted far into the night.

After signing a military convention with Germany and Austria-Hungary and an alliance treaty with Germany, Bulgaria called up its army. The general mobilization decree carried the signatures of Tsar Ferdinand and Prime Minister Vasil Radoslavov.
Notes
The article dates the decree to late on 9 September 1915 and the mobilization to 11-30 September 1915 (treaties signed 6 September), without stating the calendar; Bulgaria used the Julian calendar until 1 April 1916, so Gregorian dates may be 13 days later (an earlier draft used 22 September from another article, which matches 9 September plus 13 days). Either way the start falls in September 1915, so the month is stored. Wikidata gives September 1915 as start time, unsourced. Calendar not stated in source. Mobilization lasted 17-18 days.
Tenants in Glasgow, led by the Glasgow Women's Housing Association, protested against rent rises by landlords. The strikes were formally launched in September 1915 and involved 20,000 to 25,000 households by November, and Parliament passed a rent-freezing act.
Notes
The article body and Scottish Housing News both date the formal launch of the strikes, by the Women's Housing Association, to September 1915; the infobox and Wikidata give March to November 1915 (unreferenced), reflecting earlier resistance to evictions from February-March 1915. September 1915 is stored as the formal start. The article says the act passed on 27 November, but Hansard and the act's own Wikipedia article give royal assent on 23 December 1915. Households: 20,000 in the article, 25,000 in Scottish Housing News.

Fighting around the town of Smorgon, in present-day Belarus, ran on for 810 days. Russian troops held the Germans there and the settlement was destroyed.
Notes
Infobox gives 15 September 1915 to 4 December 1917 (Russian Wikipedia gives the same span, but the English text appears to derive from it); the body says a German cavalry raid began on 9 September 1915 and the settlement was attacked on the morning of 15 September. Dates treated as Gregorian. The "810-day" duration is the article's own figure.
On 24 September 1915 the Royal Navy Q-ship HMS Baralong, commanded by Lieutenant-Commander Andrew Wilmot-Smith, sank a German U-boat that was shelling the steamer Urbino. Baralong was flying an American flag at the time.
Notes
The U-boat was U-41. Second of the two Baralong incidents (19 August and 24 September 1915 per infobox; location given as Irish Sea, Atlantic Ocean for the pair). U-41, Urbino, the American flag and the DSO award for Wilmot-Smith are in the article body; it says Baralong had sailed from Falmouth the day before. Date matches Wikidata (one reference). German Wikipedia's Baralong-Zwischenfall page covers mainly the first incident and says the events were never officially ruled a war crime; no independent outside source for the 24 September date was found, so confidence stays medium.
Joseph Conrad's psychological novel, also issued as Victory: An Island Tale, came out from Methuen in Britain and Doubleday Page & Co in the United States. It brought Conrad popular success.
Notes
Publication date 24 September 1915 is from the English lead and infobox; German Wikipedia gives only 1915 (it also notes the novel was serialised in Munsey's Magazine in 1915), and Wikidata gives the year only, so no outside check of the day was available.
British and French forces attacked German defences in Artois and Champagne between 25 September and 8 October 1915, trying to break through. The Germans contained the attacks apart from local losses; British casualties in the main and subsidiary attacks totalled 59,247.

Notes
Infobox and lead give 25 September to 4 November 1915; the text says the battle went on until 13 October. Wikidata gives 1915-09-15 as the start, unreferenced; the article says the artillery bombardment began on 21 September and the Tenth Army attacked on 25 September.

An intense Category 4 hurricane, weaker at landfall, struck southeast Louisiana near Grand Isle on 29 September. The storm is estimated to have cost 275 lives and $13 million in damage.
Notes
Date is the landfall (29 September, per the English article). The storm formed 21 September per the English article and Wikidata (German Wikipedia says 22 September) and dissipated 1 October. German Wikipedia confirms the Category 4 peak, landfall at Grand Isle, about 275 deaths and about 13 million dollars in damage. Infobox fatalities 275-279. The English lead's claim that it was the most intense cyclone of the 1915 Atlantic season was not confirmed outside, so it is not used.

In September 1915 the Kru of the Sinoe County coast rose against the Liberian government, blockading Greenville with war canoes; by 28 September the port of Sinoe was under siege. The United States sent the USS Chester, and by September 1916 the revolt was considered all but over.
Notes
The infobox gives 28 September 1915 to September 1916, but 28 September is the date of US Chargé Bundy's telegram (FRUS 1915, doc. 759), which already reports the port of Sinoe in a state of siege. President Howard's message (FRUS 1915, doc. 758) says only that the Kru began hostilities in September 1915 by blockading Greenville with war canoes. Start stored as September 1915; end September 1916 per the article.

Wikidata gives 22 November 1915, with 17 October 1915 as start and 21 November 1915 as end. The Battle of Kosturino article dates Krivolak to 5-19 November 1915. Dates here follow this battle's own article (infobox, lead and day-by-day narrative). Calendar not stated in source. If the source's date is Old Style (Julian), the Gregorian date would be 3 November 1915.

Notes
The infobox spells the birthplace Ruzhinoy (Bialystok-Grodno District, Ober Ost); the body text and Wikidata give Ruzhany. Lead and infobox give 22 October 1915, but the article's death-age template uses 15 October 1915 (7 days apart, so not a calendar shift). Calendar not stated in source. If the source's date is Old Style (Julian), the Gregorian date would be 4 November 1915.

Jack London's science fiction novel, involving mysticism and reincarnation, was published in October 1915 by Macmillan in New York. In the United Kingdom it appeared as The Jacket.
Notes
The ISFDB entry (via its AuthorWars mirror) records 'Published October, 1915' from the first edition's copyright page, announced by Macmillan for 6 October 1915; Wikipedia and Wikidata give only 1915. No exact publication day confirmed, so month is stored.

Economy & trade
On 1 October 1915 a federal court ruled in the case United States v. Motion Picture Patents Co. that the trust, formed in December 1908 by the major American film companies, had broken the Sherman Antitrust Act by illegally restraining trade.

A strong earthquake struck Pleasant Valley in north-central Nevada late on the evening of 2 October 1915, affecting Pershing County. Damage was limited.
Notes
NOAA UTC date 1915-10-03 06:52; the row stores the local date, 2 October 1915 at 22:53 (article infobox). The magnitude is disputed and therefore not given in the title: NOAA gives Ms 7.6, while the article gives Mw 6.8 and Ms 7.7. NOAA record lists no death or injury figures. The article's lead claim that this was the strongest earthquake ever recorded in Nevada was not confirmed outside, so it is not used.

Dinosaur National Monument is proclaimed
Politics & diplomacy
President Woodrow Wilson proclaimed the area around the Dinosaur Quarry in Utah a national monument on 4 October 1915. The aim was to protect the quarry, where excavation had begun after Earl Douglass's 1909 discovery.
Notes
Category chosen as politics_diplomacy because the event is a presidential proclamation. The 1915 monument covered only the area around the quarry in Utah; the Colorado part was added in the 1938 expansion. The date of 4 October 1915 is in the infobox and body; German Wikipedia gives the year 1915 and Wikidata's date has one reference. The English lead's figure of over 800 paleontological sites was not confirmed outside and is not used.

War & conflictMedium confidence
On 21 October 1915 Mexican Sediciosos crossed the Rio Grande and assaulted a US Army Signal Corps post at Ojo de Agua, Texas. Reinforcements drove them back into Mexico after the defenders suffered heavy casualties.
Notes
Casualties per infobox: US 4 killed, 8 wounded; Sediciosos 7 killed, about 9 wounded. Infobox and lead give 21 October 1915; one Background sentence says the planned raid was in October 1916. Spanish Wikipedia gives 21 October 1915 but follows the English text. The English lead's claims that this was the last notable clash and that it led officials to send many more troops could not be confirmed outside Wikipedia, so they are not used; no outside check was available.
Cleveland Agreement signed by Czech and Slovak representatives
Politics & diplomacyMedium confidence
Representatives of the Czech and Slovak people signed an agreement in Cleveland, Ohio, at the Bohemian National Hall, pledging to seek self-determination for both nations in an independent federation.
Notes
Lead says signed on 22 October 1915; the History text says signed on 22 and 23 October 1915, after several months of negotiations. German Wikipedia gives 22 October 1915 as the single signing date, so 23 October is an end date given only by the English History text.
In October 1915 a rebellion against Iran's monarchist central government began in Gilan. Its guerrilla fighters, called Jangalis, went on to fight foreign invaders.
Notes
Month-level date. The English infobox gives October 1915 to October 1921 and the body says the movement was launched in October 1915; German Wikipedia says only that the Jangalis fought in Gilan from 1915. Wikidata gives the end as 1920-06-05, unreferenced. Calendar not stated in source (Persia).

Notes
Infobox gives 9 October 1915 to 1 January 1916. The start date rests on the English infobox and Wikidata (one reference); the English Kamerun campaign article describes Allied forces ready for the assault on Jaunde only by December 1915, and no other approved source gave the start day, so no outside check was available.

Infobox shows 17 November 1915 to 29 September 1918, but the duration template in the same infobox counts from 28 November 1915; the lead says autumn 1915 and Wikidata gives November 1915, so the month is stored. Calendar not stated in source.
Italy and Austria-Hungary fought on the Soča river on the Italian Front. The battle ended with Italy taking Mount Calvario and Oslavia, and the Italian offensive was suspended.
Notes
Start 10 November 1915 is given by English, German (first assaults) and Italian Wikipedia. The end is disputed: the English infobox and Wikidata give 2 December, Italian Wikipedia gives 5 December, so the end is stored at month level. The English casualty figures (49,500 and 32,100) were not confirmed outside and are not used.

Notes
Wikidata gives 1915-11-10 to 1915-12-04 (Italian Wikipedia also gives 10 November to 4 December 1915); the English infobox gives 10-24 November, and the body says Mackensen declared the campaign over on 24 November and Berlin on 28 November. The row stores Mackensen's declared end. Calendar not stated in source. If the source's date is Old Style (Julian), the Gregorian date would be 23 November 1915. The English aftermath figure of over 400,000 retreating soldiers and refugees was not confirmed outside and is not used.

War & conflictLow confidence
The Royal Serbian Army, with refugees and prisoners of war, retreated through the mountains of Montenegro and Albania to the Adriatic coast, from 25 November 1915 to 18 January 1916. Survivors were evacuated to Corfu.
Notes
The infobox gives 25 November 1915 – 18 January 1916, and the text says the High Command issued the formal retreat order on 25 November 1915, after the 23 November decision to retreat. Wikidata gives 25 November 1915 as the point in time (on the Julian calendar model, imported from English Wikipedia; read as Julian it would be 8 December) and 25 November 1915 to 18 January 1916 as start and end on the Gregorian model, unreferenced. Calendar not stated in source; Serbia still used the Julian calendar in 1915. If the source's date is Old Style (Julian), the Gregorian date would be 8 December 1915.
Pancho Villa's forces attacked the Sonoran border town of Agua Prieta, held by Plutarco Elias Calles for Venustiano Carranza. Calles repulsed the attack, a Constitutionalist victory.
W. E. Hill's ambiguous wife and mother-in-law drawing appears in Puck
Art & literatureMedium confidence
American cartoonist William Ely Hill published the ambiguous drawing in the humour magazine Puck, with a caption inviting readers to find both women in it.
Notes
Infobox says the image was first published in 1888 (a German postcard); the 6 November 1915 date is for Hill's version in Puck. The day rests on the English article alone: German Wikipedia (Meine Frau und meine Schwiegermutter) says only 1915 for the Puck drawing and agrees on the 1888 German postcard, and no outside source for the day was available.

Notes
Infobox gives founded 1914, when the syndication enterprises were consolidated, and German Wikipedia also says it was founded in 1914 by Hearst; the launch date of 16 November 1915 comes from the English history text alone and no outside source for it was available.

Notes
Casualties are given as about 70 killed or wounded (infobox). The English lead's claim that it was the first significant engagement between Villa's forces and the US military, and the casualty figure, could not be confirmed outside Wikipedia (no other-language article exists), so they are not used; no outside check was available.

Notes
The English article and Wikidata give only 1915. Japanese Wikipedia and the Aozora Bunko edition's first-publication note both name the November 1915 issue of Teikoku Bungaku; no day-level date found, so month is stored. The story was first collected in a book in May 1917 (Japanese Wikipedia).

Place is given as the modern states.
Gustav Meyrink's novel The Golem is published as a book
Art & literatureMedium confidence
Kurt Wolff of Leipzig issued Gustav Meyrink's Gothic novel Der Golem in book form in December 1915. It had earlier run in a periodical from December 1913 to August 1914, and it was Meyrink's first novel.
Notes
German Wikipedia says the book appeared in December 1915 from Kurt Wolff Verlag and lists the first edition as 1 December 1915; the English infobox caption dates the first edition Leipzig 1915/16. Only the month is stored because the day comes from one bibliographic line. The English claim that the book sold over 200,000 copies in 1915 is not supported: German Wikipedia says about 145,000 copies in two years, so the figure was dropped. Serialised in Die Weißen Blätter, December 1913 to August 1914.

The 6 December start is kept as the date of the Bulgarian attack on the trenches. Calendar not stated in source. If the source's date is Old Style (Julian), the Gregorian date would be 19 December 1915.

Stage, music & filmMedium confidence
The Helsinki Philharmonic Orchestra gave the first performance of the original version of Jean Sibelius's Symphony No. 5 in Helsinki, with the composer conducting, on his 50th birthday. The Finnish government had commissioned the work for the occasion.
Notes
German Wikipedia also gives 8 December 1915 in Helsinki under Sibelius, and the date coincides with his 50th birthday as stated in the article, so a calendar shift is unlikely; the second version was first played in Turku a year later and the final version in Helsinki on 24 November 1919. Finland was then part of the Russian Empire.
Hans Gross, an Austrian criminal jurist and criminologist, died in Graz, where he had held a university professorship since 1905.

War & conflictLow confidence
Bulgarian forces crossed the Drin river and entered Albania while attacking the retreating Serbian army, after occupying eastern Serbia. The occupation of eastern Albania lasted until 9 September 1917, when French troops captured Pogradec.
Notes
Calendar not stated in source; Bulgaria used the Julian calendar until April 1916, so the 10 December 1915 date may be Old Style (Gregorian 23 December 1915). No other-language article exists and no outside source on an approved site covers the date, so no outside check was available. End date given in the article: 9 September 1917 (Wikidata agrees, unreferenced).

War & conflict
Germany's 4th Army discharged chlorine mixed with phosgene toward British lines at Wieltje, north-east of Ypres. The British had been warned and held; a medical study counted 1,069 gas casualties, 120 of them fatal.
Notes
Wikidata category politics_diplomacy changed to war_conflict. Mixed chlorine and phosgene had been used against French and Russian troops from late May 1915.

Notes
The December 1915 first public performance at a gamelan gong competition in Jagaraga is given by the English article; German Wikipedia says only that the name gamelan gong kebyar was first used in 1915, and Wikidata gives the year with no reference, so the month rests on the English article and no outside check was available.

Infobox gives an Old Style date pair, 27 December 1915 (N.S.) and 9 December (O.S.), citing Shishov (2010); the two are 18 days apart rather than the 13-day Julian offset (9 December O.S. would be 22 December N.S.), so the pair is inconsistent. Wikidata gives 17 December 1915 with no reference. Only the month is stored. Persia used the Islamic calendar and Russia the Julian.
Ottoman forces under Halil Pasha arrived at Kut on 7 December 1915 and besieged the British Indian Army garrison there. The siege lasted until the garrison surrendered on 29 April 1916.
Notes
Infobox gives 7 December 1915 to 29 April 1916 (147 days). German Wikipedia also says the pursuing Ottoman forces reached Kut on 7 December 1915. Calendar not stated in source.
Russian destroyers sink two Ottoman gunboats off Kefken Island
War & conflictLow confidence
Three Russian destroyers, Derzky, Gnevny and Bespokoiny, met two Ottoman gunboats in the Black Sea and sank both. The gunboats had been dispatched to recover the German submarine UC-13, which had grounded near the Sakarya river.
Notes
Calendar not stated in source (Russian and Ottoman forces involved). Wikidata label is 'Second Battle of Kirpen Island'; the article is titled 'Battle of Kirpen Island'. Infobox lists Russian casualties as unknown. Turkish and Italian Wikipedia repeat the English text (10 December 1915), so they are not independent. If the source's date is Old Style (Julian), the Gregorian date would be 23 December 1915.
Britain and Abdulaziz Al Saud sign the Treaty of Darin
Politics & diplomacy
Abdulaziz Al Saud, ruler of Nejd and Hasa, and Sir Percy Cox for the British government signed the treaty on the island of Tarut. Britain recognised him as ruler of Najd under its protection and gave him a loan of £20,000 and arms.
Notes
Loan and arms shipment dated June 1916 in the article.
Balthazar Johannes Vorster, born in Jamestown, Cape Province, later led South Africa as Prime Minister (1966 to 1978) and then as State President (1978 to 1979).
Notes
Article infobox and early-life section give Jamestown, Cape Province. Wikidata gives Uitenhage, referenced only as imported from English Wikipedia; the article is also filed under people from Uitenhage.
Battle for Lake Tanganyika opens with the capture of Kingani
War & conflict
British motor boats Mimi and Toutou, under Geoffrey Spicer-Simson, damaged and captured the German vessel Kingani on Lake Tanganyika. This began a series of engagements that gave Britain and Belgium control of the lake by mid-1916.
Notes
Wikidata gives the end as 1916-07-01; infobox gives July 1916, stored as 1916-07. Wikidata category everyday_life changed to war_conflict.

Russian army begins the Great Retreat
War & conflictMedium confidence
Russian forces pulled back from Galicia and Congress Poland on the Eastern Front after heavy losses in the Central Powers' summer offensive. The Stavka ordered the withdrawal to shorten the front and avoid encirclement.
Notes
Start date disputed, so stored at year level. English Wikipedia's infobox gives 13 July to 19 September 1915 (13 July is when the Central Powers' offensive began, and the body describes Russian retreat orders from 22 July), German Wikipedia dates the retreat from June to the end of September 1915, and Wikidata gives 17 August to 19 September 1915 with no reference. The end in September is consistent across sources. The article marks Old Style dates separately, so its dates are taken as Gregorian.
Allied naval forces began a blockade of the Strait of Otranto, running from Brindisi in Italy across to Corfu, to stop the Austro-Hungarian Navy escaping into the Mediterranean. Patrols used steel indicator nets meant to trap submarines or warn surface vessels.
Notes
Start year disputed: the English article says the blockade was begun in 1915 (patrols with indicator nets), while German Wikipedia says the Otranto barrage was built in 1916; 1915 is stored, Wikidata also gives 1915 start and 1918 end (unsourced). No end date used. The 'over 200 vessels' figure was not confirmed outside the English article and was dropped from the interest line.
Russian avant-garde artist Kazimir Malevich made the first version of Black Square, an oil painting on linen, in 1915. He called it his breakthrough and the start of Suprematism.
Notes
Year only; calendar does not affect the stored date.
The French Army decided in 1915 to adopt the Chauchat light machine gun as the Model 1915 CSRG, and the Gladiator factory was converted to build it that year. It entered regular infantry service in 1916.
Notes
Sources disagree on when production began: the English lead says December 1915, but its production section dates Gladiator's output from April 1916 and French Wikipedia says only 1915 to 1918. Regular infantry service began June 1916. English Wikipedia gives about 262,000 made; French Wikipedia gives 262,000 in the text and 280,000 in the infobox. Year precision used. The English lead's claim that it was the most widely made automatic weapon of the war was dropped because French Wikipedia does not support it.
W. Somerset Maugham's Of Human Bondage is published
Art & literature
Of Human Bondage, a novel by W. Somerset Maugham, came out in 1915 from the publisher William Heinemann. Maugham had first meant to call it Beauty from Ashes.
Bulgarian occupation forces kill Serbian men at Surdulica
War & conflictLow confidence
Bulgarian occupation authorities detained Serbian men in the region, mostly officials, teachers, priests and former soldiers, then took them to Surdulica and killed them. An estimated 2,000-3,000 men were executed.
Notes
The timing is disputed, so only years are stored. The English infobox gives November 1915 to February 1916 (citing Lazić 2024) and its lead says between 1915 and 1916; Wikidata gives 1915 to 1916 (unsourced). But the English body places the Bulgarian round-ups after the military governor's internment order of 16 December 1916 (and the Toplica rebellion of February-March 1917), and French, Serbian and Bulgarian Wikipedia (which look like translations of an older English version, so not independent) give 1916 and early 1917; Serbian Wikipedia's local-history section speaks of 1915-1918 in Surdulica generally. Calendar not stated in source (Serbia and Bulgaria used the Julian calendar then). The 1926 exhumation mentioned in an image caption is not used in the text; Drayton's December 1918 - January 1919 interviews are stated in the article body.
International competition is held to design Skogskyrkogården cemetery
ArchitectureMedium confidence
An international design competition for a new cemetery in Enskede, south Stockholm, was announced in autumn 1914 and ended in 1915 with 53 entries. The winning entry, by Gunnar Asplund and Sigurd Lewerentz, became Skogskyrkogården.
Notes
Wikidata gives 1915 as the creation date; the cemetery itself was inaugurated in 1920 and work began in 1917. Swedish Wikipedia says the competition was announced in autumn 1914 and closed in 1915, and that the winning entry 'Tallum' was changed on the jury's advice before building. The 1915 event stored is the end of the competition.
La Gazette, a French newspaper begun in 1631, stops publishing
Art & literature
La Gazette, started by Théophraste Renaudot, first appeared on 30 May 1631 and became the voice of the Legitimist royalists. It was discontinued in 1915 as newer, specialised papers spread.
Methuen published The Rainbow, Lawrence's novel about three generations of the Brangwen family in Nottinghamshire. It was later prosecuted for obscenity.
As German forces advanced into Latvian territory, the Russian Stavka backed the plan and the tsar approved forming the Latvian Riflemen, a unit of the Imperial Russian Army.
Notes
Date disputed, so stored at year level. The English article says the tsar approved the formation on 19 July 1915, with no calendar stated; if that is Old Style (Julian) the Gregorian date is 1 August 1915. Russian Wikipedia instead dates the Grand Duke Nikolai Nikolaevich's approval of the provisional regulation on the Latvian rifle battalions to 7 (20) August 1915 and does not mention a 19 July approval. The English infobox gives July 1915 as the start. German Wikipedia confirms that about 40,000 Latvians were drafted into the division.
The Sütterlin script, designed by Ludwig Sütterlin on a commission from the Prussian education ministry in 1911, was brought into Prussian schools in 1915. It gradually replaced older German cursive.
Notes
Script was commissioned in 1911; Wikidata gives 1915. The English lead says it was taught 1915-1941 in all German schools, but the sources say it was introduced in Prussia in 1915, began replacing older cursive in the 1920s, and a modified form became part of the national curriculum in 1935 (German Wikipedia).
Maurice Maréchal and his wife Jeanne, together with H. P. Gassier, founded the satirical weekly newspaper Le Canard enchaîné in 1915. It is based in Paris.
Notes
Founders' names from the full article (the excerpt cut them off). The first issue is dated 10 September 1915 (French Wikipedia, citing the issue's own editorial; Wikidata inception also 10 September 1915); the English article gives only the year, so year is stored. The paper was relaunched on 5 July 1916 after a pause.
Franz Kafka's short story "Before the Law" first appeared in 1915 in the Jewish weekly Selbstwehr. It was later collected in Ein Landarzt, which English Wikipedia dates to 1919 and German Wikipedia to 1920.
Notes
English Wikipedia says the 1915 New Year's edition of Selbstwehr; German Wikipedia's bibliography lists Selbstwehr, volume 9, no. 34, dated 7 November 1915, which does not obviously fit a New Year (Jewish New Year fell in September 1915) edition. Neither is checked against the original issue, so only the year is stored. A Czech scholarly article also lists a printing in Wolff's almanac Vom jüngsten Tag (1916, 1917) before the 1919 Ein Landarzt collection (imprint 1920).
German Army introduces the Stielhandgranate stick grenade
Technology
The Imperial German Army brought in the first Stielhandgranate, a stick hand grenade, in 1915 to give soldiers a lighter weapon than the heavy ball-shaped grenade it began the war with. Improved models followed in 1916 and 1917.
Notes
Infobox gives design 1915-1943 and service 1915-1945; the first model is the Stielhandgranate 15, with the 16 and 17 as later modifications. Improvised stick ('hairbrush') grenades stayed in use until 1916, so the new model did not at once replace them. Russian Wikipedia also dates its introduction to 1915. The 'Potato masher' nickname is, per German Wikipedia, one the Allies used in the Second World War.
A large monument by sculptor Ladislav Šaloun was unveiled at Old Town Square in Prague to mark five hundred years since Jan Hus was executed. Public donations alone paid for it.
Notes
Wikidata also lists 6 July 1915 as the opening date, with no reference; the article gives 1915. The Radio Prague page the article cites could not be read.
Karl Kraus begins writing The Last Days of Mankind
Art & literatureMedium confidence
Karl Kraus wrote this grotesque drama of more than 200 scenes between 1915 and 1922. It is a bitter account of the horrors of the First World War.
Notes
German Wikipedia says Kraus began work on the war drama on 26 July 1915 and that it took its title in October 1915 (uncited there), with major parts written by summer 1917 and the book edition published on 26 May 1922; only the start year is stored. English Wikipedia says about a third of the text is documentary; German Wikipedia gives both a quarter and over half in different places, so no fraction is stated. Scene counts also vary (more than 200; 213 in the 1914-1918-online encyclopedia; 220 in German Wikipedia).
Kazimir Malevich painted Red Square in 1915 as part of his Suprematist work. The canvas presents a single red quadrilateral against a white background and is held by the Russian Museum.
Swedish painter Carl Larsson finished the last version of Midvinterblot in 1915, after earlier versions from 1910 onwards. It was meant for the central staircase hall of the Nationalmuseum in Stockholm and shows a Norse legend in which King Domalde is sacrificed to end famine.
Notes
The English article says the final version was shown 'where it was intended' in June 1915, but Swedish Wikipedia says it was hung there only temporarily as a trial, and both say the museum bought and permanently installed it in 1997. Swedish Wikipedia says Larsson began the final painting in May 1914 and worked on it for about a year. Year stored.
Austrian painter Egon Schiele made the large oil painting Death and the Maiden in 1915. He first called it Man and Girl, and also Entwined People. It is shown in the Belvedere in Vienna.
Kazimir Malevich made the first version of the oil painting Black Cross in 1915. It was first shown at The Last Futurist Exhibition 0,10 in Petrograd, which opened on 19 December 1915 by the Russian calendar of the time (1 January 1916 by today's calendar).
Notes
The Centre Pompidou says the painting was exhibited at 0.10 in Petrograd, the first exhibition of Suprematist works. Russian Wikipedia (Black Square article) dates the opening of 0,10 as 19 December 1915 Old Style = 1 January 1916 New Style, and Wikidata tags the exhibition dates as Julian; so the earlier 'December 1915' was an Old Style month. Wikipedia's infobox year field gives 1915-1924 because Malevich's students made later versions for the 1924 Venice Biennale (Pompidou, Spanish Wikipedia). Only the year of painting is stored; where it was painted is not stated.
An airfield north-east of Friedrichshafen, on Lake Constance, was set up when its first hangars were built. It is now an international airport in Baden-Württemberg.
Notes
German Wikipedia says the site was sought from 1913 (its infobox gives opening 1913) and treats the completion of the first airship hangar in 1915 as the airport's birth; the airport company was founded in 1928 and scheduled airline flights began in 1929. English Wikipedia says the airfield was established in 1915 when the first hangars were built. Year 1915 stored.
Germans begin building the Wire of Death on the Dutch-Belgian border
War & conflictMedium confidence
From 1915 the German occupiers of Belgium built a lethal electric fence along the Dutch-Belgian frontier, running from near Aachen towards the Scheldt and the coast. Dutch accounts record the first deaths on it by late June 1915.
Notes
English Wikipedia says construction began in spring 1915, over 200 km of 2,000-volt wire from Aix-la-Chapelle to the Scheldt, and 2,000 to 3,000 victims. Dutch Wikipedia gives 332 km running to Knokke on the coast, German Wikipedia about 300 km, and says victims range from several hundred to several thousand, with Vanneste at no fewer than 1,280. Length and death toll are therefore left out of the summary. Year stored.
Hans Lundbeck founds the company Lundbeck in Denmark
Economy & tradeMedium confidence
Hans Lundbeck founded the firm that became the Danish drug maker H. Lundbeck A/S. At first it traded in goods such as machinery, aluminium foil, artificial sweeteners and photographic equipment.
Notes
Only the infobox of English Wikipedia gives 14 August 1915 (uncited); the article text and Danish Wikipedia say 1915, and Wikidata lists 1915-01-01 unsourced. No outside source confirms the day, so the row is stored at year level.
Vladimir Mayakovsky wrote Backbone Flute, a poem of passionate love for a woman who prefers the security of her marriage, in autumn 1915. It first appeared that December, heavily cut by censors.
Notes
Written in autumn 1915; first published December 1915 in the Vzyal almanac. calendar not stated in source.
Rafael Sabatini's novel follows Sir Oliver Tressilian, a Cornish gentleman betrayed by his half-brother, forced to serve on a galley, and freed by Barbary pirates, among whom he takes the name Sakr-el-Bahr.
First Gstaad International tennis tournament is played
Sport
The first edition of the Gstaad International tennis tournament was played in 1915 at the hotel then called the Royal Hotel, Winter & Gstaad Palace, organised with the Lawn Tennis Club Gstaad.
Notes
German and French Wikipedia also date the first Gstaad tournament to 1915. The English article traces an older Swiss International Championships to 1897 held in many places, which were sometimes staged at Gstaad and were not the same event; only the Gstaad tournament's first edition is treated as this event.
Fabergé makes the Red Cross with Imperial Portraits egg
Everyday lifeMedium confidence
Henrik Wigström made the jewelled enamel Easter egg under Peter Carl Fabergé's supervision for Nicholas II of Russia. The Tsar gave it to his mother, Maria Feodorovna, at Easter. It holds five miniature portraits.
Notes
Mieks Fabergé Eggs (specialist site) says the egg was made in Saint Petersburg and gave it from Nicholas II to Maria Feodorovna. Wikipedia says it was presented at Eastertide 1915; no day given in either source. Russia used the Julian calendar then, but only the year is stored.
The company was set up in 1915 by Charles Richard Fairey with the Belgian engineer Ernest Oscar Tips, after both left Short Brothers. At first it built aircraft designed by others, under licence or as subcontractor.
University opens in Rostov-on-Don, later Southern Federal University
ScienceMedium confidence
Russian staff evacuated from Poland at the start of the First World War set up a branch of the Imperial University of Warsaw in Rostov-on-Don in 1915. A decree of the Provisional Government on 5 May 1917 later gave it the name Donskoy University.
Notes
Russian Wikipedia (Rostov State University article) says the Warsaw university moved in 1915 and that a 1917 Provisional Government decree created the university with four faculties and the name Donskoy; the English article places the four departments in 1915. The four departments were history and philosophy, medicine, physics and mathematics, and law (English article). The Russian article also says Rostov had no scientific or educational institution before the move. Calendar not stated in source.
Animator Max Fleischer developed the rotoscope in 1915, a way of tracing over film footage frame by frame to make realistic animated movement. He used it in his Out of the Inkwell series.
Notes
Source does not name a place; region taken from Fleischer being Polish-American. Fleischer filed his rotoscope patent application on 6 December 1915 (granted 9 October 1917) per the Fleischer Studios site. Wikidata also lists 1914 for first use, unsourced.
Alfred A. Knopf Sr. founded the publishing house in New York in 1915 with Blanche Wolf, then his fiancée and later his wife, who is counted as co-founder. The couple travelled abroad often and became known for publishing writers from Europe, Asia and Latin America.
Notes
Harry Ransom Center's organizational history says the firm was founded in 1915 in New York, with Alfred setting up the business and Blanche Wolf then his fiancée; Wikipedia credits both as founders. The firm was incorporated in 1918.
The Federal League, a US professional baseball league that rivalled the National and American Leagues, ended after the 1915 season, when owners of those leagues bought out half of its team owners.

Safeway traces its origins to M. B. Skaggs's Idaho grocery store
Economy & tradeMedium confidence
The Safeway supermarket chain dates its beginnings to 1915, when M. B. Skaggs took over his father's cash-only grocery store in American Falls, Idaho. It is now a subsidiary of Albertsons.
Notes
1915 is the founding year in the Safeway article's infobox and categories. The article's own history starts the chain in the 1920s, and a Skaggs biography and an outside reference work say that in 1915 M. B. Skaggs bought his father's American Falls store (the Skaggs biography gives 15 August 1915). The Safeway name was used by Sam Seelig's separate chain (founded 1914 per the reference work) and spread to Skaggs's stores after the 1926 merger. The row therefore records the Skaggs store as the origin, year only.
Equitable Building in Lower Manhattan is completed
ArchitectureMedium confidence
The 38-storey Equitable Building at 120 Broadway, designed by Ernest R. Graham, was finished in 1915 after work began in 1913. It was controversial for lacking setbacks.
Notes
Source gives completion as 1 February 1915 (work completed) and 1 May 1915 (building completed); year used. Wikidata gives 1915.
Metro Pictures Corporation, a forerunner of Metro-Goldwyn-Mayer, began in 1915 as a film distribution company, later producing films in New York, Los Angeles and Fort Lee, New Jersey.
Notes
Article gives several founding dates: infobox 23 June 1915, lead 'early 1915' in Jacksonville, Florida, body 'February 1915' as a distribution company. Its first release (Satan Sanderson) came on 29 March 1915 and its first own production (Sealed Valley) on 2 August 1915, so the June date cannot be the start of operations. Stored as year because the founding dates differ. The lead dates the purchase to 1919, the body to 1920 (by Marcus Loew). Infobox headquarters is New York City.
Arthur C. Townley, a former Socialist Party organizer, founded the Nonpartisan League in North Dakota. It spoke for small farmers and merchants and called for state control of mills, grain elevators and banks.
Solomon Bellows, later Saul Bellow, was born in Lachine, Quebec. He became a Canadian and American writer who won the Pulitzer Prize and the 1976 Nobel Prize in Literature.
Notes
Birth day disputed. The infobox and lead give 10 June 1915, the birthday Bellow celebrated; the early-life section says Jewish Genealogical Society-Montreal records point to 10 July 1915 and quotes his New York Times obituary calling the records inconclusive (June or July 10). Wikidata gives 10 June (citing GND, BnF, Britannica, SNAC and others) and also 10 July (citing American Novelists of Today, 1951). Stored at year precision because the candidate days fall in different months. Britannica and nobelprize.org could not be opened (HTTP 403).
Proceedings of the National Academy of Sciences publishes its first issue
ScienceMedium confidence
The National Academy of Sciences set up the journal in 1914, and its first issue appeared in 1915. It is a multidisciplinary scientific journal.
Notes
Wikidata gives 1915 as the founding year; the article says the National Academy of Sciences established the journal in 1914 and its first issue appeared in 1915. This row records the first issue.
Frank and Lester Patrick, who owned the Pacific Coast Hockey Association, set up the Seattle Metropolitans as an expansion team. The club played in the league until it folded in 1924.
Rudolph E. Schirmer Sr. and Oscar Sonneck conceived and established The Musical Quarterly, a journal on music, in 1915. Sonneck edited it until his death in 1928.
Notes
The article's claim that this is the oldest academic music journal in America was not confirmed by an independent source (French Wikipedia only repeats it), so it was left out.
Harvey Spencer Lewis founded AMORC, a Rosicrucian organization, in the United States. It later opened lodges in several countries and is now headquartered in San Jose, California.
Notes
French Wikipedia says Lewis founded AMORC in New York on 1 April 1915; German Wikipedia says it was founded in 1915 in New York City and its first lodge was set up there in May 1915. That day is not confirmed by an independent source, so only the year is stored. The English article notes Lewis either founded AMORC or renamed his Rosicrucian Research Society (1904) as AMORC.
Vilhjalmur Stefansson makes the first known visit to Mackenzie King Island
ExplorationMedium confidence
Vilhjalmur Stefansson made the first known visit to this uninhabited island in Canada's Queen Elizabeth Islands in 1915. It was later named after William Lyon Mackenzie King.
Notes
The article says Stefansson made the first known visit in 1915. Nunatsiaq News places his find of the large 'First Land' in 1915 but says it was later found to be separate islands, and the Borden Island article dates its first sighting to 1916, so whether he landed on this island is not independently clear. The 26th-largest ranking was not confirmed outside the article and was dropped.
The Pepsodent Company of Chicago brings out Pepsodent, a minty toothpaste, in the United States.
Notes
The English article gives two dates for the Unilever purchase (1942 in the lead, 1944 in the body); an outside reference work gives 1944, so 1944 is used. Wikidata inception 1915 is unsourced; the article's introduction date is 1915.
The first state championship of the Rio de Janeiro state football league was played, soon after the state's first football association was founded. Ararigboya of Niterói were the first champions.
First officially counted Campeonato Cearense is played
SportMedium confidence
The Ceará state football championship counts its official history from 1915, when Ceará won the first officially recognised title, with Stella as runners-up. Clubs had contested a state title since 1906, but the federation recognised the 1915 to 1919 titles only in 2008.
Notes
The English article's infobox says founded 1915 and its notes say Ceará's 1915 to 1919 titles were recognised only in 2008 and a 1914 title was not counted as official. Portuguese Wikipedia says club-run state championships date from 1906, a league was set up in 1912 and renamed in 1915, and cites an act of the state federation (11/2008) for counting 1915 as the first official edition. So 1915 is the start of the official count rather than of state football competition.
First Campeonato Pernambucano football season is played
Sport
The first edition of Pernambuco's state football championship in Brazil was played in 1915 and won by Flamengo de Recife, a club that no longer exists.
Notes
The infobox gives two founding dates: 1915 as amateur leagues and 1937 as the professional championship. The History section and Portuguese Wikipedia both say the first edition was played in 1915 with five clubs and won by Flamengo of Recife, which Portuguese Wikipedia says was dissolved in 1949.
Russia, China and Mongolia sign the Treaty of Kyakhta
Politics & diplomacyMedium confidence
A three-party treaty among Russia, Mongolia and China was signed at Kyakhta. Russia and China recognised Outer Mongolia's autonomy within Chinese territory, and Mongolia accepted Chinese suzerainty.
Notes
The lead gives 25 May 1915 and the infobox 29 May 1915; neither states a calendar, and Wikidata stores 25 May 1915 as a Julian date (7 June 1915 Gregorian), imported from Russian Wikipedia. With three candidate days, only the year is stored.

Ananta Samakhom Throne Hall is completed in Bangkok
ArchitectureMedium confidence
The Ananta Samakhom Throne Hall, a royal reception hall in Dusit Palace, was finished after eight years of construction, under King Vajiravudh.
Notes
English Wikipedia gives completion in 1915 and construction from 1908 (foundation stone laid 11 November 1908). Thai Wikipedia also gives completion in Buddhist Era 2458 (1915) and a formal inauguration on 11 January 2459 BE (11 January 1916), which I could not confirm elsewhere, so only the year is stored. The English lead says the king commissioned the hall in 1908, but its history section places the commission about a year after 1906.
Nanking Higher Normal School, forerunner of National Central University, is founded
Everyday lifeMedium confidence
After the Republic of China was proclaimed, Nanking Higher Normal School was set up to replace the Liangjiang Higher Normal School. The university now based in Taoyuan City, Taiwan, traces its origin to it.
Notes
Article says 1915 is the year most often cited for the founding of the university.
Kyota Sugimoto created the first practical typewriter for Japanese script, finishing a prototype in 1914 and patenting it in Japan in 1915 (patent No. 27877). His machine carried 2,400 of the thousands of kanji characters, and a US patent followed in 1917.
Notes
Japanese patent No. 27877 (1915) and US patent No. 1,245,633 (1917) from the Kyota Sugimoto article. Nipponica (via Kotobank) says he finished a prototype in 1914 and obtained the patent in 1915; Daijisen says the machine went on sale in 1916. The Japanese typewriter article's line that he obtained the patent rights in 1929 conflicts with these and is not used. Character count: 2,400 per Wikipedia; Mypedia says about 3,000.
The clock tower at Kowloon station, Tsim Sha Tsui, was finished in 1915 as part of the station, which opened on 28 March 1916. Built of red brick and granite, it is 44 metres high.
Notes
Hong Kong's Antiquities and Monuments Office says the clock tower was erected in 1915 as part of the terminus, construction began in 1913 and the terminus opened on 28 March 1916; the tower is 44 m, of red brick and granite. The clocks and bell were installed later and started keeping time in March 1921.
Tamisuke Yokogawa starts the venture that became Yokogawa Electric
Economy & tradeMedium confidence
In 1915 Tamisuke Yokogawa set up a research institute for electric meters in Shibuya, Tokyo, the origin of Yokogawa Electric. The venture was incorporated five years later as Yokogawa Electric Works Ltd.
Notes
The English infobox gives 1 September 1915 (uncited), but the article text, Japanese Wikipedia and Wikidata give only the year 1915, and no approved outside source confirms the day, so the row is stored at year level. The history section describes the 1915 start as a research institute for electrical meters in Shibuya, Tokyo, with incorporation in 1920; the infobox lists Tamisuke Yokogawa, Ichiro Yokogawa and Shin Aoki as founders (Japanese Wikipedia also names all three).
A period of mass starvation began on Mount Lebanon during the First World War and lasted until 1918. Estimates of the dead vary widely, from about 80,000 to 240,000, and most victims were Christians.
Notes
English Wikipedia says about 200,000 died out of 400,000 and that most were Maronites. French Wikipedia's text says estimates range from 80,000 to 240,000 (all figures include deaths from epidemics), its infobox gives 100,000 to 350,000, and it cites Courbage's 155,000 of 415,000 (37%); German Wikipedia gives about 100,000 of 450,000. The toll is therefore disputed and the summary gives the wide range. Year stored: the article places the famine in 1915-1918, although it describes grain shortages from November 1914.
Battle of Kara Killisse is fought on the Caucasus front
War & conflictLow confidence
Russian forces under Nikolai Yudenich fought the Ottoman Third Army under Abdul Kerim Pasha at Kara Killisse during the Caucasus campaign of the First World War. The battle was indecisive, though the Russians treated it as a victory.
Notes
Dates disputed inside the article, so stored at year level: the English infobox and Wikidata (unreferenced) give 27-31 July 1915, while the body dates the battles to 5-8 August 1915, and the lead places the engagement within the Russian Alashkert operation (9 July-3 August; Russian Wikipedia gives Old Style dates there with Gregorian equivalents in brackets). The infobox says Russian victory, but the body calls the battle indecisive with the Russians only partly succeeding, so the summary follows the body. Troop numbers (40,000 against 60,000) and Ottoman losses were not confirmed outside and are not used. Calendar not stated in the article.
· Diyarbekir vilayet, Ottoman Empire · Middle East
Genocide of Christians in Diyarbekir vilayet
War & conflictMedium confidence
In 1915, Ottoman authorities carried out a systematic anti-Christian genocide in Diyarbekir vilayet under the governor Mehmed Reshid. It killed most of the Armenians and Syriac Christians living there.
Notes
The article says the genocide began in April 1915 and continued into 1916, so only the year is stored. It also says there were no orders from the capital until the end of June and that Reshid acted on his own authority until then, while historian Raymond Kévorkian argues that the CUP leadership probably gave the order for the killing of Assyrian Christians; the wording 'ordered by' was therefore replaced with 'under'. The 83% figure is the total of Jacques Rhétoré's contemporary tally in the article's table.
Mass killing of Assyrians begins in Ottoman-occupied Azerbaijan
War & conflictMedium confidence
While Ottoman troops occupied Persia's Azerbaijan province in 1915, Ottoman forces and pro-Ottoman Kurds began mass killings of Assyrian civilians, part of the Sayfo, the killing and deportation of Assyrian and Syriac Christians during World War I.
Notes
Wikidata gives January 1915. The first mass killings are dated to the Ottoman occupation of Azerbaijan, January to May 1915, so year precision is used. Calendar not stated in source. The infobox frames the genocide as 1914-1924.
Russian forces defeat the Ottomans at the Battle of Dilman
War & conflictMedium confidence
At Dilman in Qajar Iran, Russian forces under Tovmas Nazarbekian, helped by Armenian and Assyrian volunteers, defeated an Ottoman army. By the end, the Ottomans had lost 3,500 soldiers killed.
Notes
Date disputed. English Wikipedia and Wikidata (which copies it) give 15 April 1915. Russian Wikipedia gives 18 April (1 May) 1915, citing the Russian military historian Airapetov for the 3,500 Ottoman dead, and an Ottoman-side passage commented out in the English article (from Kevorkian) also says hostilities began 18 April/1 May. The two readings fall in different months (April or May), so only the year is stored. The article's claim that most Ottoman troops were Kurds who almost all deserted was not confirmed outside and is left out.
During the Russian Empire's wartime occupation, an administration backed by Armenian volunteer units takes shape around Van after the siege of Van, with Aram Manukian as de facto head. Armenians sometimes called it the Republic of Van.
Notes
Infobox gives April-May for the start; text says administration formed around April 1915. Candidate region Oceans replaced. Calendar not stated in source.
Narekavank, a tenth-century Armenian monastery near Lake Van, stopped functioning during the Armenian genocide of 1915. It was reportedly demolished around 1951, and a mosque now stands on the site.
Notes
Year only. Ottoman territory in 1915. English Wikipedia says the monastery was abandoned in 1915 and reportedly demolished around 1951 (citing Sevan Nisanyan); French Wikipedia says it was destroyed in 1915 during the genocide. Wikidata gives a 1915 end, unsourced. Demolition date is therefore disputed; 1915 is when it ceased to function.
Sultan Hussein Kamel establishes the Order of the Nile
Politics & diplomacy
Sultan Hussein Kamel of Egypt set up the Order of the Nile in 1915 to reward people who had given useful service to the country. When the monarchy ended in 1953 it was reconstituted as a Republic of Egypt honour.
Notes
Candidate category was religion_philosophy; changed to politics_diplomacy.
Hussein Kamel of Egypt created this order in 1915 to honour women in many walks of society. Today it is a dynastic order for women of the Egyptian royal family, very rarely awarded.
Notes
Wikidata gives 14 April 1915, imported from Russian Wikipedia; the article gives the year 1915.
Johannesburg Art Gallery building opens to the public
Art & literature
The gallery's purpose-built building in Joubert Park, designed by Sir Edwin Lutyens, opened to the public without a ceremony in 1915, soon after the First World War began. The collection had been shown since 1910 in temporary premises.
Notes
The infobox gives established 1910, when the collection was first opened to the public in temporary premises (Wits, per English Wikipedia). The Friends of JAG centenary article and the City's heritage plaque both say the building opened to the public in 1915; the foundation stone was laid in 1911. The row is about the 1915 opening of the building.
Anti-colonial uprisings broke out in southern and western Madagascar against French rule, lasting from 1915 to 1917. The rebels resisted heavy taxation and forced labour; the revolts were put down and leaders punished.
Notes
Source gives the span 1915-1917 only; end year 1917 used as date_end.
German South West African mark is replaced by the pound
Economy & tradeMedium confidence
South Africa's occupation of German South West Africa in 1915 brought British currency back and ended the short life of the colony's own paper marks. Local emergency notes in marks were still being issued in 1916 to 1918.
Notes
English Wikipedia says the 1915 South African occupation officially replaced the mark with the pound. Two outside sources agree on the direction: the Monetary History of Namibia (liganda.ch) says the 1915 occupation brought back British currency, and Nortje (Western Cape Numismatic Society, 2025) says the 1914 mark notes circulated only briefly before the 1915 occupation. Local emergency notes in marks were issued 1916-1918 and only South African notes were official from 1919, so the changeover was not a single day. Wikidata end 1915 is a year-precision value with no reference. Year stored.

Gija people are shot dead in the Mistake Creek massacre
War & conflictMedium confidence
At Mistake Creek in the East Kimberley of Western Australia, Gija people were shot dead and their bodies burned. Sources put the number killed anywhere from about 7 to 32, and name Michael Rhatigan and two Aboriginal men he employed as the attackers.
Notes
Date and toll disputed. English Wikipedia gives 28 March 1915 (inferred from a newspaper of 1 April saying 'on Sunday') and 8 to 32 killed; the University of Newcastle's Colonial Frontier Massacres database dates it between 1 May and 30 June 1915 and lists 7 victims (range 7-10), citing a constable's report of five or six shot and burned. Neither is clearly better, so only the year is stored. Rhatigan was cleared at a coroner's inquest and Nipper found not guilty, per the article. Infobox spells the surname Ratigan in one field and Rhatigan in others.
The New Guinean pound becomes the currency of the Territory of New Guinea
Economy & tradeMedium confidence
Australian-occupied New Guinea adopted the pound, replacing the New Guinean mark used under German rule. It was worth the same as the Australian pound and stayed in use until 1966.
Notes
Year from the lead, which dates the currency 1915-1966. The lead places the switch at the end of World War I, but Australia occupied German New Guinea in 1914; the English article on the New Guinean mark says the mark was replaced by the Australian pound in 1915. Wikidata end date 1966.

Vilhjalmur Stefansson sights Brock Island
ExplorationMedium confidence
In 1915, during the Canadian Arctic Expedition, Vilhjalmur Stefansson became the earliest known European to see this island. It lies in the Queen Elizabeth Islands and is uninhabited.
Notes
Day and month not given. Expedition ran 1913-1916.
Polish mathematician Wacław Sierpiński described the fractal now named for him in 1915. His article aimed to give an example of a curve, and the pattern had appeared as decoration centuries earlier.
In a 1915 paper on the calculus of relatives, Leopold Löwenheim presented the result later called the Löwenheim-Skolem theorem, named after him and Thoralf Skolem.
Notes
Source gives no place of publication; region set to Global. The article's line calling it the first significant result of what became model theory was left out: the one outside source opened (Stanford Encyclopedia model theory entry) did not confirm it and credits the field's founding to 1940s work.
