Stock Market Crashes on Black Tuesday
The stock market crashed on what became known as Black Tuesday, with 16 million shares traded in a single day. The crash marked the beginning of the Great Depression and the worst economic crisis in American history.
Why It Matters
Black Tuesday led to sweeping financial reforms including the Securities Act of 1933 and the creation of the Securities and Exchange Commission, fundamentally changing how the federal government regulates financial markets.
