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".
Repeal of Prohibition in the United States
During this period, support for Prohibition diminished among voters and politicians. John D. Rockefeller Jr., a lifelong nondrinker who had contributed between $350,000 and $700,000 to the Anti-Saloon League, announced his support for repeal because of the widespread problems he believed Prohibition had caused. Influential leaders, such as the du Pont brothers, led the Association Against the Prohibition Amendment, whose name clearly asserted its intentions.
