The 18th Amendment to the U.S. Constitution–which banned the manufacture, transportation and sale of intoxicating liquors–ushered in a period in American history known as Prohibition. Prohibition was ratified by the states on January 16, 1919 and officially went into effect on January 17, 1920, with the passage of the Volstead Act. Despite the new legislation, Prohibition was difficult to enforce. The increase of the illegal production and sale of liquor (known as “bootlegging”), the proliferation of speakeasies (illegal drinking spots) and the accompanying rise in gang violence and other crimes led to waning support for Prohibition by the end of the 1920s. In early 1933, Congress adopted a resolution proposing a 21st Amendment to the Constitution that would repeal the 18th. The 21st Amendment was ratified on December 5, 1933, ending Prohibition.
