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the beginning of what is known as the Gangster Era, a time that roughly spans from 1919 until 1933 when Prohibition was repealed.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.
California wine
Worldwide recognition seemed imminent until January 16, 1919 when the 18th Amendment ushered in the beginning of Prohibition. Vineyards were ordered to be uprooted and cellars were destroyed. Some vineyards and wineries were able to survive by converting to table grape or grape juice production. A few more were able to stay in operation in order to continue to provide churches sacramental wine, an allowed exception to the Prohibition laws. However, most went out of business. By the time that Prohibition was repealed in 1933, only 140 wineries were still in operation.
