Prohibition
Prohibition in the United States focused on the manufacture, transportation, and sale of alcoholic beverages; however, exceptions were made for medicinal and religious uses. Alcohol consumption was never illegal under federal law. Nationwide Prohibition did not begin in the United States until January 1920, when the Eighteenth Amendment to the U.S. Constitution went into effect. The 18th amendment was ratified in 1919, and was repealed in December 1933 with the ratification of the Twenty-first Amendment.
Anti-Italianism
When the United States enacted Prohibition in 1920, the restrictions proved to be an economic windfall for those in the Italian-American community already involved in illegal activities, and those who had fled from Sicily. They smuggled liquor into the country, wholesaled and sold it through a network of outlets and speakeasies. While other ethnic groups were also deeply involved in these illegal bootlegging activities, and the associated violence between groups, Italian Americans were among the most notorious. Because of this, Italians became associated with the prototypical gangster in the minds of many, which had a long-lasting effect on the Italian-American image.
