9Joe Frazier – Championship Reign: 4 Years, 10 Months, 18 Days
‘Smokin’ Joe Frazier was an American heavyweight boxer who was one of the most famous boxers of the 60s and 70s. He defeated Buster Mathis by TKO in 1968 to become a Heavyweight Champion, a title he successfully defended 9 times before losing it
to George Foreman in 1973. One of Frazier’s successful defenses was against the then undefeated Muhammad Ali, who had been stripped of the title in 1967 for his refusal to fight in the Vietnam War. The build-up to the Frazier/Ali fight was huge, and it became a cultural event that transcended boxing. Ali was looking to regain the title he had never lost, and Frazier was eager to prove to the world that Ali was not invincible. Frazier proved his point by defeating Ali by unanimous decision and winning ‘The Fight of the Century’.
