Prohibition in the United States was a nationwide constitutional ban on the sale, production, importation, and transportation of
alcoholic beverages that remained in place from 1920 to 1933. It was promoted by the "dry" crusaders, a movement led by rural Protestants and social
Progressives in the Democratic and Republican parties, and was coordinated by the
Anti-Saloon League, and the
Woman's Christian Temperance Union.
Prohibition was mandated under the
Eighteenth Amendment to the United States Constitution. Enabling legislation, known as the
Volstead Act, set down the rules for enforcing the ban and defined the types of alcoholic beverages that were prohibited. For example, religious uses of wine were allowed. Private ownership and consumption of alcohol was not made illegal under federal law; however, in many areas local laws were more strict, with some states banning possession outright. Nationwide, Prohibition ended with the ratification of the
Twenty-first Amendment, which repealed the Eighteenth Amendment, on December 5, 1933.
