Prohibition Ends in the U.S. (1933): Prohibition was the period in United States history in which the manufacture, sale, and transportation of intoxicating liquors was outlawed. It began officially on January 16, 1920 (exactly a year after the ratification of the 18th Amendment to the U.S. Constitution) and ended with the ratification of the 21st Amendment on December 5, 1933. Many people called prohibition the "noble experiment" and debates continue over whether or not making alcohol illegal made society any safer.
