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the beginning of what is known as the Gangster Era, a time that roughly spans from 1919 until 1933 when Prohibition was repealed.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.
Repeal of Prohibition in the United States
Journalist H. L. Mencken, writing in 1925, believed the opposite to be true:
Some supporters of Prohibition, such as Charles Stelzle who wrote "Why Prohibition!" (1918), believed that prohibition would eventually lead to reductions in taxes, since drinking "produced half the business" for institutions supported by tax dollars such as courts, jails, hospitals, almshouses, and insane asylums. In fact, alcohol consumption and the incidence of alcohol-related domestic violence were decreasing before the Eighteenth Amendment was adopted. Following the imposition of Prohibition, reformers "were dismayed to find that child neglect and violence against children actually increased during the Prohibition era."
