Black Tuesday was the catastrophic stock market crash of October 29, 1929, that marked the dramatic end of the Roaring Twenties and triggered the Great Depression. On this day, panic selling overwhelmed the New York Stock Exchange as millions of shares were traded and prices collapsed. Investors lost fortunes within hours, banks faced severe strain, and confidence in the financial system shattered. What began as a market correction quickly spread into a global economic crisis, leading to widespread unemployment, business failures, and human suffering. Black Tuesday remains a powerful reminder of the dangers of speculation, overconfidence, and fragile economic systems.
