Al Capone was a notorious American gangster who became the co-leader of the Chicago Outfit during the Prohibition era of the 1920s-1930s. As head of a large smuggling operation, he helped supply the illegal demand for alcohol in Chicago after the 1918 prohibition. Capone presented himself as a businessman, but used violence and intimidation against rivals, with around 200 murders attributed to his gang. Though a criminal, he was admired by some for flouting the unpopular dry laws. Capone's empire ended when he was convicted of tax evasion in 1931 and sentenced to prison.
