Which U.S. stock-market crash began after the 1929 peak and helped usher in the Great Depression?

The Wall Street Crash of 1929 began after the market peak and helped usher in the Great Depression.

The Dow Jones Industrial Average reached a major peak on September 3, 1929. Heavy selling followed in October, including Black Thursday on October 24, Black Monday on October 28, and Black Tuesday on October 29. These sessions became the most famous phase of the collapse.

The crash destroyed enormous amounts of paper wealth, but it was not the sole cause of the Great Depression. Bank failures, falling demand, debt burdens, deflation, policy mistakes, and declining international trade all contributed to the severe economic contraction of the 1930s.

The 1929 crash is often described as a single day, but the market’s decline unfolded over an extended period. It also differs from the 1987 crash, whose one-day percentage loss was much larger but was followed by a far shorter recession rather than the decade-long catastrophe associated with the Great Depression.
