Write a paragraph about the great depression, 1929 - 1939

The Great Depression was the worst and longest downturn in the world.The Great Depression began in the United States, which experienced its worst effects. However, some argue that the Depression began about 10 years earlier in Europe but the United States assumed that it was immune to such a downturn. The Great Depression happened because  of overproduction and low pays in the agricultural sector. Farmers kept supplying mass amounts of crops and prices dropped due to the increase. The stock market crashed on 29th October 1929 (Black Tuesday) and investors including banks lost billions of dollars. Investors in the stock market could not pay their loans. These included real estate companies. People demanded their deposits from banks in panic and as a result, there was less money in circulation. The resultant economic downturn lasted for 10 years and spread to other economies especially America’s trade partners. Nations had to have major changes done to their policies and institutions to recover from the Great Depression.
