Ending December 5, 1933, Nationwide Prohibition was a period of nearly fourteen years of U.S. history in which the manufacture, sale, and transportation of liquor was made illegal.
January 17, 1920, a grim day in American History, the Eighteenth Amendment went into effect banning alcohol. As it fueled unintended consequences such as organized crime and further political corruption, almost immediately the amendment starting losing support. By 1933, criminal activity and the inefficient means to enforce the law, coupled with the economy's need for jobs and tax revenue brought the ratification of the Twenty First Amendment and an end to Prohibition.
The Eighteenth Amendment is the only one to have ever been repealed.
There's your history lesson. Now, let's have a beer!
