Organized crime flourished in the United States during the 1920s due to Prohibition. Criminal organizations led by famous gangsters like Al Capone illegally profited from the underground sale of alcohol. As law enforcement struggled to control widespread bootlegging and related criminal activities, mob bosses consolidated power and influence over many cities and towns. Prohibition fueled the rise of powerful crime syndicates that employed violence and corruption to operate lucrative criminal enterprises throughout the decade until alcohol was legalized again in 1933.
