On what date did the 1929 Wall Street Crash begin with Black Thursday’s sharp sell-off?

The 1929 Wall Street Crash began with Black Thursday on October 24, 1929.

Trading volume surged as investors rushed to sell shares on the New York Stock Exchange. Bankers attempted to calm the market by buying heavily traded stocks, and prices temporarily recovered. That intervention did not end the underlying panic. A second collapse followed on October 28, known as Black Monday, and an even more severe plunge came on October 29, known as Black Tuesday.

The crash followed years of rising share prices, widespread speculation, and purchases made with borrowed money. It did not by itself cause the entire Great Depression, but it damaged confidence, reduced wealth, and contributed to the economic contraction that followed.

Black Thursday is sometimes mistakenly treated as the whole crash. It was the first major panic day in a sequence that continued into late October and ultimately produced a prolonged bear market.
