Black Thursday
From Conservapedia
Oct. 24, 1929 is referred to as “Black Thursday.” On this day the New York Stock Exchange crashed, signaling the beginning of The Great Depression in the United States. Many lost everything and the economies of European nations were also suffered in the wake of the depression.
The Stock Market did not recover to the high it reached in 1929, 381 points on the Dow Jones Industrial Average, until 1949.
