Prohibition in the United States spanned exactly 13 years, from January 17, 1920, to December 5, 1933, marking one of the most ambitious social experiments in American history. The nationwide ban on the production, importation, transportation, and sale of intoxicating liquors was intended to reduce crime, improve health, and strengthen social morality, but its legacy proved far more complex.

The countdown began the moment the 18th Amendment took effect on January 17, 1920, and it ended only when the 21st Amendment was ratified on December 5, 1933. This precise timeline is often
