January 2020: Prohibition

On January 16, 1920, in accordance with the 18th Amendment to the U.S. Constitution, the National Prohibition Act (also known as the "Volstead Act") enforced the prohibition against the production, importation, transportation, and sale of alcoholic beverages in the United States. For the next 13 years, halting the flow of illegal alcohol proved to be the bane of the nation's Prohibition agents but a boon for organized crime, speakeasies, and bootleggers. Learn more about Prohibition using census data and records.
