Prohibition Party
The Prohibition Party's proudest moment came in 1919, with the passage of the 18th Amendment to the United States Constitution, which outlawed the production, sale, transportation, import and export of alcohol. The era during which alcohol was illegal in the United States is known as "Prohibition".

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 which trafficked in alcohol. Prohibition was repealed in 1931. States and localities retained the right to remain "dry", and to this day, a handful still do.
