The stock market crash that led to the Great Depression occurred in 1929, specifically in late October. This crash is often marked by the collapse of stock prices, especially from October 24, known as Black Thursday, and culminating in the catastrophic drop on October 29, dubbed Black Tuesday. The sudden and dramatic decline in stock market values devastated investors, banks, and businesses, leading to widespread panic and loss of confidence in the economy. This event triggered a severe economic crisis that lasted throughout the 1930s, resulting in massive unemployment, bank failures, and a significant shift in economic policies and practices in the United States and worldwide.
