Before Muhammad Ali’s rise to prominence, Sonny Liston was the most dominant boxer in the world. Liston took the heavyweight title from Floyd Patterson in September 1962 and successfully defended his belt in the rematch 10 months later.
Ali wanted a shot at Liston, but Liston didn’t want to fight the brash 22-year-old. So Ali hatched a plan to get Liston to agree to a fight.
Ali rented a bus and drove it from Chicago to Liston’s house in Denver. He told the press to be there to meet him when he arrived, with the bus covered in slogans like “Sonny Liston Will Go in Eight” and “World’s Most Colorful Fighter.”
The bus rolled up to Liston’s place at 3 a.m. and the champ came out in his pajamas to see it. He eventually agreed to a fight, which Ali would win, along with the rematch.

In one of the most iconic and controversial moments of his career, Ali stands over Sonny Liston and yells at him after knocking the former champ down in the first round of their 1965 rematch. Skeptics dubbed it "the Phantom Punch," but films show Ali's flashing right caught Liston flush, knocking him to the canvas. Refusing to go to a neutral corner, Ali stood over Liston and told him to "get up and fight, sucker."
At 22-years-old, Cassius Clay (Muhammad Ali) battered the heavily favored Sonny Liston in a bout that shook the boxing world. The fight ignited the career of one of sports' most charismatic and controversial figures, whose bouts often became social and political events rather than simply sports contests. At the peak of his fame, Muhammad Ali was the best known athlete in the world. Liston, one of the most feared heavyweight champions in history, was a 1-8 favorite over the young challenger known as the Louisville Lip. But Clay, here stinging the champ with a right, used his dazzling speed and constant movement to dominate the action and pile up points.

For the 18-year-old from Louisville, here atop the medal stand after his Olympic victory, all roads led from Rome. Clay finished his amateur career with a record of 100-5 and made his professional debut two months after the Games.
Undefeated in his first 17 pro fights, Clay mugged for the camera before the start of his 1963 bout against Doug Jones in Madison Square Garden.
Trainer Angelo Dundee urged his young charge to get serious before the opening bell against Jones. Clay followed instructions and emerged from a tough fight with a unanimous decision victory. Three months later he would stop Henry Cooper and close out 1963 at 19-0.
A seemingly hysterical Clay taunted Sonny Liston during the pre-fight physical for their 1964 bout. He had consistently baited the Big Bear during the lead-up to the fight, saying he was going to "use him as a bearskin rug ... after I whup him." The Miami Boxing Commission would fine Clay $2,500 for his outburst at the physical.
"I shook up the world!" an emotional Clay hollered to ringside reporters after his shocking defeat of Liston. And he did just that, claiming the heavyweight title at age 21 after a clearly beaten Liston, complaining of a shoulder injury, failed to answer the bell for the seventh round.
Draped in shadow, the young king — now known as Muhammad Ali — stared down the camera during a photo shoot in April 1965, one month before his rematch against Sonny Liston.
As Liston lingered on the canvas and the referee, former heavyweight champ Jersey Joe Walcott, tried to control Ali, the 2,434 spectators on hand in the Lewiston, Me., hockey arena — a record low for a heavyweight championship fight — tried to make sense of what all that had happened in less than two minutes after the opening bell.
The celebration over Liston continued. In a chaotic ending, Ali was awarded a knockout when Nat Fleischer, publisher of The Ring, informed referee Jersey Joe Walcott from ringside that Liston had been on the canvas for longer than 10 seconds after Ali knocked him down. The bout remains one of the most controversial in boxing history, with many observers insisting that Liston took a dive.
Ali's second title defense came in November 1965, against former two-time heavyweight champion Floyd Patterson. During the build-up to the bout, the normally soft-spoken Patterson earned the new champ's wrath by refusing to call Ali by his Muslim name. At the weigh-in, Ali's glare made it clear that he intended Patterson to pay for the disrespect.
