History

Historical Context

The Wall Street Crash of 1929 began on October 24, marking the onset of the Great Depression. The Dow Jones Industrial Average fell nearly 25% in just two days, leading to widespread bank failures and a 90% drop in stock values by 1932. This event reshaped U.S. economic policy, highlighting the critical role of government regulation in stabilizing markets, a lesson echoed in today's economic climate.
