On June 20, 1967, boxing legend Muhammad Ali was given a prison sentence for refusing to join the US military and fight in the Vietnam War. He was sentenced to five years behind bars and fined $10,000, an unusually harsh sentence aimed at breaking his anti-war resistance.

“Why should they ask me to put on a uniform and go 10,000 miles from home and drop bombs and bullets on Brown people in Vietnam while so-called Negro people in Louisville are treated like dogs?” argued Muhammad Ali.
