The stock market crash of October 29, 1929, known as Black Tuesday, signaled the beginning of the Great Depression in the United States. This catastrophic event occurred after months of speculative investing, leading to unsustainable stock prices. When the market collapsed, it wiped out billions in wealth, causing panic. People rushed to withdraw money from banks, leading to widespread bank failures. The economic fallout spread globally, resulting in massive unemployment and significant declines in industrial production. This economic crisis had long-lasting effects, prompting changes in government policy and regulations that aimed to stabilize the economy and prevent future depressions.
