Explanation:

The Great Depression was a severe worldwide economic depression between 1929 and 1939 that began after a major fall in stock prices in the United States. The economic contagion began around September 4, 1929, and became known worldwide on Black Tuesday, the stock market crash of October 29, 1929.
