Chicago
The ratification of the 18th amendment to the Constitution in 1919 made the production and sale (including exportation) of alcoholic beverages illegal in the United States. This ushered in the beginning of what is known as the Gangster Era, a time that roughly spans from 1919 until 1933 when Prohibition was repealed. The 1920s saw gangsters, including Al Capone, Dion O'Banion, Bugs Moran and Tony Accardo battle law enforcement and each other on the streets of Chicago during the Prohibition era. Chicago was the location of the infamous St. Valentine's Day Massacre in 1929, when Al Capone sent men to gun down members of a rival gang, North Side, led by Bugs Moran.
Oklahoma Beer Act of 1933
The anti-prohibition legislation was enacted into law in conjunction with the Blaine Act and Cullen-Harrison Act. The 72nd United States Congress proposed the Twenty-first Amendment to the United States Constitution as endorsed by John Nance Garner and Charles Curtis on February 20, 1933. The Eighteenth Amendment to the United States Constitution or Volstead Act was repealed upon ratifying the twenty-first constitutional law abolishing Prohibition in the United States on December 5, 1933.
