The Twenty-first Amendment (Amendment XXI) to the United States Constitution repealed the Eighteenth Amendment to the United States Constitution, which had mandated nationwide Prohibition on alcohol on January 16, 1919. The Twenty-first Amendment was ratified on December 5, 1933. It is unique among the 27 amendments of the U.S. Constitution for being the only one to repeal a prior amendment and to have been ratified by state ratifying conventions.
Section 1. The eighteenth article of amendment to the Constitution of the United States is hereby repealed.
Section 2. The transportation or importation into any State, Territory, or possession of the United States for delivery or use therein of intoxicating liquors, in violation of the laws thereof, is hereby prohibited.
Section 3. This article shall be inoperative unless it shall have been ratified as an amendment to the Constitution by conventions in the several States, as provided in the Constitution, within seven years from the date of the submission hereof to the States by the Congress.
The Eighteenth Amendment to the Constitution had ushered in a period known as Prohibition, during which the manufacture, distribution, and sale of alcoholic beverages was illegal. Passage of the Eighteenth Amendment in 1919 was the crowning achievement of the temperance movement, but it soon proved highly unpopular. Crime rates soared under Prohibition as gangsters, such as Chicago's Al Capone, became rich from a profitable, often violent black market for alcohol. The federal government was incapable of stemming the tide: enforcement of the Volstead Act proved to be a nearly impossible task and corruption was rife among law enforcement agencies. In 1932, wealthy industrialist John D. Rockefeller, Jr. stated in a letter:
When Prohibition was introduced, I hoped that it would be widely supported by public opinion and the day would soon come when the evil effects of alcohol would be recognized. I have slowly and reluctantly come to believe that this has not been the result. Instead, drinking has generally increased; the speakeasy has replaced the saloon; a vast army of lawbreakers has appeared; many of our best citizens have openly ignored Prohibition; respect for the law has been greatly lessened; and crime has increased to a level never seen before.
