What name is given to the stock-market crash that began in the United States on October 24, 1929?

The stock-market crash that began in the United States on October 24, 1929, is called the Wall Street Crash of 1929.

October 24 became known as Black Thursday after heavy selling struck the New York Stock Exchange. Further collapses followed on October 28 and October 29, creating the sequence remembered as Black Monday and Black Tuesday. The crash destroyed large amounts of paper wealth and severely weakened public confidence.

The market had risen dramatically during the 1920s, while many buyers used borrowed money to purchase shares. When prices fell, margin calls forced additional selling, accelerating the decline. The crash contributed to the Great Depression but was not its sole cause.

The event is distinct from the Panic of 1907 and the 1987 Black Monday crash. Those crises occurred in different financial and economic settings, despite similar names.
