It was a stroke of luck—bad luck—that got Muhammad Ali into the ring for the first time. The Louisville, Kentucky, native was 12 years old when his brand-new bicycle was stolen. The police officer to whom Ali reported the theft happened to own a boxing gym—and became his first coach.

Ten years later, in 1964, Ali, then still known by his birth name, Cassius Clay, became the world heavyweight champion when he defeated reigning titleholder Sonny Liston. The athlete, who earned the nickname “The Greatest,” would go on to win that title two more times, as well as an Olympic gold medal and numerous honors for his civil rights activism and humanitarian work.

There was, of course, another side to the legend: his domestic life. As we gear up for the release of the Prime Video series The Greatest, which explores the prizefighter’s rise to prominence, we’re looking back at photos of Ali in his off-duty hours.

Life in Chicago

Days after becoming the heavyweight champion, Ali announced his conversion to the Nation of Islam, changed his name, and then relocated to Chicago, where the controversial religion’s headquarters are based. (He later converted to Sunni Islam). In 1967, Ali cited his religious beliefs when he refused to serve in the US Army during the Vietnam War. His boxing license revoked and his championship title stripped, Ali entered a period of exile. He is pictured in his Chicago home the following year, reading a book by Nation of Islam leader Elijah Muhammad. The athlete shared the dwelling with his second wife, Khalilah Camacho-Ali, whom he married at the residence on August 17, 1967. The single-story brick house was in the Avalon Park neighborhood and was a fully furnished gift from the Nation of Islam.
