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".
Prohibition in the United States
However, some scholars have attributed the crime during the Prohibition era to increased urbanization, rather than to the criminalization of alcohol use. In some cities, such as New York City, crime rates decreased during the Prohibition era. Crime rates overall declined from the period of 1849 to 1951, making crime during the Prohibition period less likely to be attributed to the criminalization of alcohol itself.
