Eighteenth Amendment to the United States Constitution

The Eighteenth Amendment (Amendment XVIII) to the United States Constitution established the prohibition of alcohol in the United States. The amendment was proposed by Congress on December 18, 1917, and ratified by the requisite number of states on January 16, 1919. The Eighteenth Amendment was repealed by the Twenty-first Amendment on December 5, 1933, making it the only constitutional amendment in American history to be repealed.

The Eighteenth Amendment was the product of decades of efforts by the temperance movement, which held that a ban on the sale of alcohol would ameliorate poverty and other societal problems. The Eighteenth Amendment declared the production, transport and sale of intoxicating liquors illegal, although it did not outlaw the actual consumption of alcohol. Shortly after the amendment was ratified, Congress passed the Volstead Act to provide for the federal enforcement of Prohibition. The Volstead Act declared that liquor, wine and beer qualified as intoxicating liquors, and were therefore prohibited. Under the terms of the Eighteenth Amendment, Prohibition began on January 17, 1920, one year after the amendment was ratified.

Although the Eighteenth Amendment led to a decline in alcohol consumption in the United States, nationwide enforcement of Prohibition proved difficult, particularly in cities. Alcohol smuggling (known as rum-running or bootlegging) and illicit bars (speakeasies) became popular in many areas. Public sentiment began to turn against Prohibition during the 1920s, and 1932 Democratic presidential nominee Franklin D. Roosevelt called for its repeal.
