The Great Depression was a severe worldwide economic depression in the decade preceding World War II.

It was the longest, most widespread, and deepest depression of the 20th century, and is used in the 21st century as an example of how far the world's economy can decline. The depression originated in the United States, starting with the stock market crash of October 29, 1929 (known as Black Tuesday), but quickly spread to almost every country in the world.
