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".
Three-tier system (alcohol distribution)
In 1933 the 18th Amendment was repealed by the 21st Amendment. (Previously, the 18th Amendment had outlawed alcohol in the US in 1919 and led to Prohibition in 1920.) Section 2 of the 21st Amendment specifies that the power to control alcohol resides with the states, leaving each state to decide when and how to repeal Prohibition.
