Black Tuesday started in October 29, 1929 it was the day the stock market crashed. It was also the day The Great Depression started. Once the stock market crashed people tried to sell their stocks, but nobody was buying them. The Stock Market Crash was just the beginning of the depression. Banks also started closing so this brought more panic to the country. People were making massive withdraws from the banks and this caused other banks to close. Businesses and industry were also affected. The lack of people buying things made some businesses to cut back on wages and fire employees. Farmers were also affected from the depression and this was called The Dust Bowl. Some farmers were hit harder than others. The ones that go it the worst had borrow money even though they were already in debt. Over time one thing led to another like Roosevelt and the New Deal. In the end President Roosevelt was the hero. The end of the Great Depression was when World War II started.
