The Dow Jones Industrial, 1928–1930

The Wall Street Crash of 1929 was the greatest stock market crash in the history of the United States.

It happened in the New York Stock Exchange on Tuesday October 29, 1929, now known as Black Tuesday. Bank failures followed, resulting in businesses closing. This caused worldwide panic, which started the Great Depression. Stock prices did not reach the same level until late 1954.
