Muhammad Ali became the world’s greatest boxer, and in doing so, transcended the sport itself to become the most famous man on earth.
As Cassius Clay, Ali won the Olympic gold medal and the Heavyweight Championship before being stripped of his title for protesting the war in Vietnam.
He eventually returned to boxing a hero, after becoming a key figure in the anti-war and civil rights movements, and has gone down as one of the greatest Heavyweight boxers of all time.

Muhammad Ali’s world titles
Ali was a three-time world champion throughout his career, with his reigns spanning between 1964 and 1979.
He won his first belt from Sonny Liston in 1964. His second was from George Foreman in 1978, and his final one was against Leon Spinks in 1978, becoming the first man to hold the title three separate times.
Muhammad Ali vs Sonny Liston
Ali was the huge underdog going into his fight with Sonny Liston in 1964. He forced the then-heavyweight champion to give up in the seventh round, handing Ali (then called Cassius Clay) his first world title in boxing.
However, the second fight is one of the most controversial in boxing history. Ali knocked out Liston in the first round with a “Phantom Punch” that had people raising suspicion of a fix, something that is debated to this very day.
Muhammad Ali vs Joe Frazier
Some of Ali’s best fights were his trilogy of bouts with “Smokin'” Joe Frazier. Frazier upset Ali in Madison Square Garden to hand him his first-ever loss, becoming a worldwide star overnight by beating “The Greatest”.
The hard-hitting fighter then lost the rematch, before the “Thrilla in Manila” ended their trilogy when Ali knocked out Frazier in the Philippines.
Muhammad Ali vs Larry Holmes
Ali’s worst defeat came near the end of his career. He challenged Larry Holmes to a fight after coming out of retirement, aiming to become the first four-time Heavyweight champion in history.
Sadly, Ali was thoroughly beaten by Holmes, who picked apart the former champion before the referee ended the bout in the tenth round.
