What was the Great Depression and When did the Great Depression take place?

On October 29, 1929, the U.S. stock market crashed.

This meant that the value of stocks went way down, because everyone sold their stocks in a panic. This stock market panic was caused by many factors, including risky investments and overproduction of products.

The crash resulted in the Great Depression, which spread over the United States and became worldwide in the early 1930s.
