The document summarizes the key events of the Great Depression in the United States. It describes how the stock market crash of 1929 led to widespread bank failures as investors who bought stock on margin could not repay their loans. This caused the economy to collapse as industry, banking and commerce declined sharply. President Hoover initially asked businesses to voluntarily address the economic crisis but did not intervene significantly. When Franklin D. Roosevelt was elected in 1932, he launched the New Deal which aimed to provide relief for the needy, recovery of the economy, and reform of the financial system through increased government spending and regulation. Within his first 100 days in office, Congress passed over 15 bills as part of the New Deal.
