When and where did al Capone operate?

Al Capone operated primarily in Chicago during the 1920s, a time when Prohibition was in effect in the United States. He became the notorious leader of the Chicago Outfit, engaging in various criminal activities, including bootlegging, gambling, and violence against rival gangs. His influence peaked during the Roaring Twenties, making him one of the most infamous gangsters in American history. Capone's reign effectively ended with his arrest in 1931 for tax evasion.
