On Black Thursday, 24 October 1929, prices on the New York Stock Exchange plunged as trading hit a record, and Black Tuesday followed five days later; by July 1932 stocks had lost about 90 percent of their pre-crash value. Earlier that year, on St Valentine's Day, seven men tied to a Chicago gang were lined up against a garage wall and shot, two of the gunmen dressed as police officers. In Rome, Mussolini's Italy and the Holy See signed the Lateran Treaty, making Vatican City a sovereign state. Hollywood held its first Academy Awards, a private dinner over in 15 minutes. In Mandatory Palestine, riots over access to the Western Wall left 133 Jews and 116 Arabs dead, and in Nigeria thousands of Igbo women rose against warrant chiefs chosen by the colonial authorities. In the first British election open to women aged 21 to 29, Ramsay MacDonald became prime minister; Carl Benz, father of the car, died; and in January a sailor called Popeye first appeared in a comic strip.

Why it is interesting. Prices kept sliding until July 1932, when stocks stood about 90 percent below their level before the crash.
Notes and dating details
Lead says the crash began in October 1929 and is most associated with 24 and 29 October; the date range is those two days. Wikidata gives year 1929, start 24 October and end 29 October. Decline continued to 8 July 1932.
Italy and the Holy See sign the Lateran Treaty in Rome
· Rome, Italy · Europe
On 11 February 1929 Mussolini's Italy and Pius XI's Holy See ended the Roman question. Under it Vatican City became a sovereign state ruled by the Holy See, and Italy promised the Church payment for the Papal States it had lost.
Why it is interesting. The agreement that ended the Roman question gave the world the independent state of Vatican City.
Notes and dating details
Signed 11 February 1929; the Italian Parliament ratified on 7 June 1929 (Wikidata also gives 7 June 1929 as a start date and 3 June 1985 as an end date).
Seven men are murdered in Chicago's Saint Valentine's Day Massacre
· Chicago, United States · North America
On 14 February 1929 seven men tied to Chicago's North Side Gang were shot in a garage in Lincoln Park. Gunmen lined them against a wall and fired Thompson submachine guns and a shotgun. Police arrested several gang members, but lack of evidence stopped a case from going forward.
Why it is interesting. Two of the gunmen were dressed as police officers.
Notes and dating details
The lead says none of those arrested were charged; a later passage says Jack McGurn, John Scalise and Albert Anselmi were charged with the murders and the charges were dropped for lack of evidence.
On 24 July 1929 the pact, in which signing states pledged to give up war as a means of settling disputes, came into force once enough nations had deposited their ratifications. By the end of 1929 it had 57 parties.
Why it is interesting. Though many historians judge it ineffective, the pact later gave legal footing to the crime against peace tried at Nuremberg and Tokyo.
Notes and dating details
Signed in Paris on 27 August 1928; the Soviet Union and its western neighbours put it into effect early through the Litvinov Protocol of 9 February 1929.

Jews are massacred in Hebron during the 1929 Palestine riots
· Hebron, Mandatory Palestine (now West Bank) · Middle East
On 24 August 1929 sixty-seven or sixty-nine Jews were killed in Hebron and many others badly hurt, their homes looted and synagogues ransacked. Rumours that Jews planned to take control of the Temple Mount had stirred the attackers. British authorities soon evacuated all of Hebron's Jews.
Why it is interesting. The killings and the British evacuation that followed broke a Jewish presence in Hebron that had lasted for centuries, though many families came back in 1931.
Notes and dating details
Lead gives the death toll as sixty-seven or sixty-nine.
On 21 June 1929 the Cristero War, fought in central and western Mexico since August 1926, came to an end. US Ambassador Dwight Morrow brokered talks between the Mexican government and the Church, which then stopped backing the fighters.

Demonstrations and riots began in late August 1929, centred on Jerusalem, Safed and Hebron. In a week of violence 133 Jews were killed by Arabs and 116 Arabs were killed, mostly by Mandate police. Seventeen Jewish communities were evacuated.
Why it is interesting. Historians disagree about the cause, some blaming stirred-up fears and others Zionist leaders' stance and land disputes.
Notes and dating details
Dates 23-29 August from lead and infobox; Wikidata gives 29 August 1929 only.
Voters went to the polls on 30 May 1929. No party won a majority: Baldwin's Conservatives took the most votes, but MacDonald's Labour won the most seats, and Ramsay MacDonald replaced Stanley Baldwin as prime minister.

Safed's Jewish community is attacked during the 1929 Palestine riots
· Safed, Mandatory Palestine (now Israel) · Middle East
On 29 August 1929, during the wider riots over access to the Western Wall, Arab mobs attacked the Jewish quarter of Safed, setting houses and shops on fire and killing a number of residents. Reported casualty figures vary.
Why it is interesting. The British-appointed Shaw Commission, set up to examine the causes of the riots, later visited the town.
Notes and dating details
The Safed section of the article gives 29 August 1929, and German Wikipedia also gives the Safed massacre as 29 August 1929. The article's casualty figures for Safed differ (18-20 Jews killed in one place, 18 in another, about 45 killed or wounded in the Shaw Report), so none is used. Same overall happening as the Palestine riots row in another pack.
Soviet and Chinese forces clash over the Chinese Eastern Railway

Some details uncertain.
In 1929 the Chinese Northeastern Army seized the Chinese Eastern Railway to gain sole control. The Soviet Union answered with force, attacking Chalainor on 17 August, and made the Chinese return to joint administration of the railway.

Notes
English Wikipedia's Curtiss-Wright article places Wright Aeronautical in Dayton, Ohio; its Wright Aeronautical article says the company was headquartered in Paterson, New Jersey, citing the Paterson Museum, and that it merged with Curtiss on 5 July 1929. The summary therefore names no city for Wright.

Hans Schemm founds the National Socialist Teachers League
Politics & diplomacySome details uncertain
The National Socialist Teachers League, a Nazi Party teachers' union first called the Organization of National Socialist Educators, is usually dated to 1929. Hans Schemm, a former schoolteacher and Gauleiter of Bayreuth, founded and first led it.
Notes
The English article and the commonly cited date give 21 April 1929 as the founding day. The German article says the official founding was in 1927 in Hof, that the 21 April 1929 date rests on a later correction, and that the group began from a 1926 meeting; the year is kept at 1929 with low confidence. Its seat from 1936 was the House of German Education in Bayreuth.
The Catalan Opening gets its name at the Barcelona 1929 tournament
Sport
At Barcelona in 1929 the tournament organisers asked Savielly Tartakower for a new variation as a tribute to Catalonia's chess past, and the opening took the region's name. White plays d4 and c4 and develops the king's bishop to g2.
Notes
Before Tartakower's use at Barcelona 1929 the line had already appeared in a few games (for example Berlin 1928), so the year marks the naming and the commissioned variation, not a first use.

Notes
Year only. The present league dates from 2000 (Wikidata gives 30 June 2000 as an alternative). The Polish article says the national championship was run from 1929 to 2000 by the volleyball federation and lists YMCA Łódź as 1929 champion; the English text lists the same winner but does not describe the 1929 tournament further.

Year only. English text: origins date back to 1929, contests until the civil war in 1936. French winners table also lists a 1928 entry (Agueda Norma, Seville); Spanish article says the contest ran as Senorita de Espana 1929-1936 and resumed in 1960 (English text says pageants were not allowed until 1961, while its own table lists a 1960 winner).
The foundation that will build Foch Hospital in Suresnes is recognised
Medicine & epidemicsSome details uncertain
In 1929 a Franco-American medical foundation was officially recognised to build and run a hospital at Suresnes, near Paris. English Wikipedia says Consuelo Vanderbilt and Winnaretta Singer helped establish it. It was named for Marshal Ferdinand Foch, who died that year, and the hospital itself opened in 1936. It is now one of the largest teaching hospitals in the Île-de-France region.
Notes
English Wikipedia says the hospital was established in 1929. French Wikipedia says that in 1929 the Franco-American medical foundation of Mont Valérien (the Marshal Foch Foundation) was recognised as a public-interest body, to build and run the hospital; the first stone was laid on 20 March 1931, building began in 1932, the hospital opened in 1936 and was officially inaugurated on 25 October 1936. Vanderbilt's and Singer's roles in 1929 come from English Wikipedia only; French Wikipedia mentions Singer only for a 1947 gift. Year precision.

Everyday lifeSome details uncertain
Jenny Vanparys was the first woman officially crowned Miss Belgium, in 1929, in the national beauty pageant. A first contest to find Belgium's most beautiful girl had been held in 1928.
Notes
Year only. The surname is spelled Vanparys in the English prose and Vanparays in the English and French winners tables. English history text: first contest in 1928, first official crowning in 1929; the French article says the pageant has run since 1928 and lists a 1928 winner (Koyaert) without calling that contest unofficial.
The arms maker DWM came under the control of the so-called Quandt Group around 1929. Its original parent, Ludwig Loewe & Company, also merged with the Gesellschaft für Elektrische Unternehmungen that year; Loewe had created DWM in 1896 by uniting its weapons and ammunition production.
Notes
Year only. The English text says DWM was taken over by the Quandt Group in 1929; the German article says Günther Quandt took control of the company (then called Berlin-Karlsruher Industrie-Werke AG) in 1928. Wikidata labels 1929 a dissolution, but the sources describe a takeover and a merger of the parent firm, not a closure.

Notes
The source gives two start dates, 1 August or February 1929, and a UPU entry dated 1 January 1929 that precedes the treaty, so year precision is used. Wikidata's 11 February 1929 is the Lateran Treaty date. Related to the Lateran Treaty and Vatican City founding rows.

SportSome details uncertain
Panellinios Basket, a professional club in Athens, was founded in 1929, and its parent athletic club dates from 1891. Its name means Pan-Hellenic, or the Greek nation.
Notes
Year only. The infobox dates the basketball club to 1929 and the lead says founded in 1929; the honours and seasons tables give a 1928-29 title and the French article lists a 1929 title, so the founding and the first title are close together but the exact order is not settled.

In 1929 the 16th Zionist Congress restructured the Palestine Zionist Executive and renamed it the Jewish Agency for Palestine, the working arm of the World Zionist Organization. The Mandate for Palestine had called for such a body.
King Fouad I opened Alexandria Stadium in 1929 in the Moharram Bey district of Alexandria. It staged the inaugural ceremony of the 1951 Mediterranean Games.
Notes
Year only. The English lead calls it the oldest stadium in Egypt and Africa, while the French article says only that it is the oldest in the country, so only Egypt is claimed here.

In 1929 two teams working independently found adenosine triphosphate in muscle. One was Cyrus Fiske and Yellapragada Subba Rao at Harvard Medical School. Both were racing to build a test for measuring phosphorus.
Notes
The article names one discoverer only as Jendrassik.
Kurt Gödel first proves the completeness theorem for first-order logic
Science
In 1929 Kurt Gödel first proved the completeness theorem, which links truth in all models of a theory with provability from its axioms in first-order logic. Leon Henkin later simplified the proof, and Gisbert Hasenjaeger simplified Henkin's version in 1953.
Wolfgang Köhler describes the takete-maluma shape and sound test
ScienceSome details uncertain
Wolfgang Köhler described the test in his 1929 book Gestalt Psychology, building on an earlier experiment by Uznadze. Readers were shown two forms and asked which was called takete and which maluma. People tend to pair soft-sounding words with rounded shapes.
Notes
Lead dates the discovery generally to the 1920s, when Uznadze and Köhler documented the pattern; 1929 is the year of Köhler's book. Wikidata gives 1929.
In 1929 Alexander Lippisch and Robert Kronfeld invented the variometer, an instrument telling a glider or aircraft pilot how fast the machine is climbing or descending. Glider pilots watch it almost constantly to find rising or sinking air.
Notes
Body gives invention in 1929 by Lippisch and Kronfeld; another sentence, quoting Ann Welch, places Kronfeld's early use in 1930.
J. D. Bernal proposes the Bernal sphere space settlement
Technology
In 1929 John Desmond Bernal first proposed the Bernal sphere, a space settlement meant as a permanent home. His original design was a hollow, non-rotating spherical shell filled with air.
Cuno Hoffmeister discovers BL Lacertae, at first taken for a star
Science
Cuno Hoffmeister found BL Lacertae in 1929 and it was taken for an irregular variable star inside the Milky Way. In 1968 John Schmitt identified it as a bright, variable radio source. It is in fact an active galaxy far outside the Milky Way.
Jacobson publishes Progressive Relaxation, setting out a muscle-relaxation method
Medicine & epidemicsSome details uncertain
