Which weekday gave its name to the Wall Street crash of October 29, 1929?

The Wall Street crash of October 29, 1929, is known as Black Tuesday.

Black Tuesday followed Black Thursday on October 24 and Black Monday on October 28. On October 29, investors traded roughly 16 million shares on the New York Stock Exchange, a record at the time, as prices plunged amid panic selling.

The crash marked a major turning point in the United States, but it was not the sole cause of the Great Depression. Falling production, bank failures, debt problems, unemployment, and international economic weaknesses also contributed to the prolonged crisis. The Dow Jones Industrial Average continued falling after October 1929 and did not reach its eventual low until July 1932.

A common mistake is to treat Black Tuesday as one isolated event. The crash was a sequence of severe selling days, with October 29 becoming the best-known date because of its scale and symbolism.
