1. What year did the Great Depression occur?
kondaur [170]

Answer:

August 1929 – March 1933

Black Tuesday was an abrupt end to the rapid economic expansion of the roaring 20's, and is widely considered to be one of the causes behind the beginning of The Great Depression.

It began after the stock market crash of October 1929, which sent Wall Street into a panic and wiped out millions of investors.

World War II seems to mark the end of the Great Depression. During the war, more than 12 million Americans were sent into the military, and a similar number toiled in defense-related jobs. Those war jobs seemingly took care of the 17 million unemployed in 1939.
