Prohibition
Prohibition in the United States focused on the manufacture, transportation, and sale of alcoholic beverages; however, exceptions were made for medicinal and religious uses. Alcohol consumption was never illegal under federal law. Nationwide Prohibition did not begin in the United States until January 1920, when the Eighteenth Amendment to the U.S. Constitution went into effect. The 18th amendment was ratified in 1919, and was repealed in December 1933 with the ratification of the Twenty-first Amendment.
Culture of the United States
A movement to ban alcoholic beverages, called the Temperance movement, emerged in the late 19th century. Several American Protestant religious groups and women's groups, such as the Women's Christian Temperance Union, supported the movement. In 1919, Prohibitionists succeeded in amending the Constitution to prohibit the sale of alcohol. Although the Prohibition period did result in lowering alcohol consumption overall, banning alcohol outright proved to be unworkable, as the previously legitimate distillery industry was replaced by criminal gangs that trafficked in alcohol. Prohibition was repealed in 1933. States and localities retained the right to remain "dry", and to this day, a handful still do.
