The 18th Amendment established Prohibition in the United States from 1920 to 1933, banning the production, importation, transportation, and sale of alcoholic beverages. However, Prohibition had unintended consequences as it led to the rise of illegal speakeasies and bootlegging operations run by organized crime like Al Capone. While Prohibition supporters hoped to reduce crime and corruption, the period instead saw a rise in criminal activity related to the illegal alcohol trade. Prohibition was later repealed with the 21st Amendment in 1933 due to its failure to achieve its moral aims and the growth of lawlessness under prohibition.
