Step-by-step explanation:
There was the Depression of 1920-1921. It happened after the first World War and affected US and the United Kingdom. Deflation in prices and decrease in product output caused a lot of economic problems.
Veterans returning from war could not find job due to the slow economy. The high unemployment rate caused other social problems.
The Depression was followed by rapid economic growth in the rest of the 1920's. The prosperity lasted until the stock market crash in 1929; followed by the Great Depression in the 1930s.
