Prohibition (United States)

The United States enacted Prohibition of alcoholic beverages through the Eighteenth Amendment of the Constitution and Volstead Act in 1920 during the administration of Woodrow Wilson. During the period, the production, transportation, and distribution of alcohol were banned. The Prohibition was supported by the Temperance Movement, politicians such as William Jennings Bryan, and groups such as Ku Klux Klan. However, during this period a black market of alcohol flourished and violent gangs such as Al Capone's developed. In 1933, the 21st Amendment was ratified and the Prohibition was formally repealed.
