The Wall Street Crash of October 1929 was the most devastating financial event in the history of the United States. On October 24, 1929, a day that became known as Black Thursday, the stock market experienced a massive sell-off as investors panicked and began selling their shares in large numbers. This triggered a wave of selling that lasted for several days, causing the stock market to lose a significant portion of its value. In the years leading up to the crash, many investors had been buying stocks on margin, which means they borrowed money to invest in the market. The crash had a devastating impact on the U.S. economy, leading to widespread unemployment, poverty, and homelessness. It also had a ripple effect on the global economy, as countries around the world were connected through trade and finance.
