Al Capone was America's most notorious gangster during the 1920s Prohibition era in the United States. He grew up in Brooklyn and joined gangs as a teenager before moving to Chicago in 1919, where he rose to power in the criminal underworld by controlling alcohol and prostitution rings. Capone orchestrated notorious killings like the 1929 St. Valentine's Day Massacre and provided charity during the Depression. However, he was eventually convicted of tax evasion in 1931 and sentenced to 11 years in prison, dying in 1947 while incarcerated.
