The 1929 Wall Street Crash reached its most infamous panic session, known as Black Tuesday, on October 29, 1929.
On that day, investors traded millions of shares on the New York Stock Exchange as prices collapsed. The selling followed Black Monday, October 28, when the Dow Jones Industrial Average had already fallen sharply. Black Thursday, October 24, marked the first major wave of panic selling, but October 29 became the crash’s best-known date.
The crash did not cause the Great Depression by itself, but it severely damaged confidence and wealth. Banks, businesses, and individual investors were exposed to falling share prices, while economic problems continued to worsen afterward. The Dow had reached a pre-crash high in September 1929 and did not recover that level until 1954.
A common mix-up is treating Black Tuesday as the only day of the crash. It was the climactic session of a broader collapse that unfolded over several weeks and had international consequences.
