If Muhammad Ali was in his time the most famous person in the world, it was as much a tribute to his talent for provocation as to his boxing. He was a glorious athlete, of course, his white-tasseled feet a blur to match his whizzing fists. But his legacy as a global personality owes more to that glint in his eye, to his capacity for tomfoolery, to his playfulness. He was a born prankster, giddy in his eagerness to surprise, and the world won’t soon forget his insistence upon fun.
Fighting in the far corners of the earth, when that was still done, he was our most popular ambassador for a quarter of a century, advancing the American doctrine of self-satisfaction. His practiced malarkey—the doggerel of doom, the ritual belittlement—didn’t so much enliven his sport as it created a whole new form of entertainment. Really, there was boxing, and there was Ali—who died late Friday at the age of 74—and everybody knew the difference. In time his artful application of nonsense would be revealed as a facade, covering a deeper mission of empowerment. But watching him emerge in Zaire, Manila or even Cleveland was to witness a one-man comic relief effort. He was a traveling circus unto himself, the highest embodiment of self-confidence.
It must be said, first of all, that Ali was, just as he used to boast, the Greatest of All Time (which in later years became the typically playful acronym—GOAT—that branded his projects). He won the heavyweight title three times, in an era of ungodly competition. Neither Joe Louis nor Rocky Marciano faced so many dangerous fighters still in their primes. Ali’s trilogy with Joe Frazier provided enough drama in the first bout alone to be deemed mythic. Then there was the fight with George Foreman, when Ali, many thought, was being sent to his doom but instead invented an almost comical escape, the rope-a-dope. Not to mention bouts with Sonny Liston, Ken Norton, Earnie Shavers, killers all. In his heyday, at least, Ali fought not for survival but for his own entertainment. He presented his ring art as a kind of jazz, fully improvisational, performed to the whimsical score in his head.

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.
Cassius Clay punches Zbigniew Pietrzykowski of Poland during their gold medal bout at the 1960 Rome Olympics. Clay defeated Pietrzykowski 5-0 for the light heavyweight gold medal.
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.
In cruelly efficient performance, Ali punished Patterson — who was hobbled by a painful back injury — seemingly toying with the former champ throughout the bout, hitting him at will and calling, "What's my name?" before finally winning on a 12th-round TKO.
Capping off a five-fight campaign in 1966, Ali faced Cleveland Williams in the Houston Astrodome on Nov. 14. Known as the Big Cat, the heavily-muscled Williams was a power puncher who had racked up 51 knockouts in 71 fights. But he was also 33, barely recovered from a gunshot wound sustained the year before, and up against a young champion very much in his prime. Ali wasted little time in unleashing a withering attack.
Float and sting: In a display of speed and combination punching unmatched in heavyweight history, Ali overwhelmed Williams from the start. The challenger, here down for the third time in round 2, would be saved by the bell before referee Harry Kessler could count him out, but it would only postpone the inevitable.
Ali dropped Williams again early in the third round, and Kessler waved the mismatch over at 1:08 of the third.
In a multiple-exposure portrait, Ali demonstrates his signature double-clutch shuffle during a photo shoot in December 1966.
Ali sits in the locker room before his February 1967 fight against Ernie Terrell. Like Patterson before him, Terrell refused to call the champion by his Muslim name. Also like Patterson, he paid a stiff price, as Ali punished Terrell for 15 ugly rounds before winning by unanimous decision.
Outside the Armed Forces Examining and Entrance Station in Houston in April 1967, Ali spoke to the press about his refusal to be inducted into military service. Among those on hand was ABC's Howard Cosell, who would be a staunch supporter of the fighter's stance. The decision cost Ali his boxing license and his heavyweight title, and he was sentenced to five years in prison but remained free pending an appeal.
In professional exile for three and a half years because of his draft case, Ali sought to return to boxing in 1970. He began with a night of exhibition bouts at Morehouse College in Atlanta, where before going into the ring, he shared a locker room laugh with actor and comedian Lincoln Perry (right), better known by his stage name of Stepin Fetchit. The friendship between the two black icons would later be examined in an acclaimed play by Will Power, Fetch Clay, Make Man.
After the Atlanta Athletic Commission at last granted Ali a license, the deposed champion went back into serious training. He was, as ever, in the capable hands of trainer Angelo Dundee, here wrapping boxing's most famous fists at the 5th Street Gym in Miami in October 1970.
With his return to the ring scheduled for Oct. 26, 1970 in Atlanta, against dangerous contender Jerry Quarry, Ali made it clear to all who would listen that he was on a mission to reclaim the title that had been stripped of him.
Reel to spiel: For the ever-loquacious Ali, even a rare moment of down time — like this afternoon in 1970 in a Miami hotel room — was a chance to do some talking.
Despite Ali's long layoff, his comeback campaign would include no easy tune-up bouts. He stopped Quarry in three rounds on Oct. 26, 1970, then, just six weeks later — an unthinkably short interlude by today's standards — took on Argentine contender Oscar Bonavena in Madison Square Garden. Here, Ali fires a right at the rugged and awkward Bonavena, who took the fight to the former champion all night.
After a long, often sloppy bout, Ali — here being held back by referee Mark Conn — produced one of the most dramatic finishes of his career, dropping Bonavena three times in the 15th and final round to automatically end the fight. The win cleared the way for a showdown with Joe Frazier, the man who had taken the heavyweight title in Ali's absence.
On the night of March 8, 1971, the eyes of the world were on a square patch of white canvas in the center of Madison Square Garden. There, Ali and Joe Frazier met in what was billed at the time simply as The Fight, but has come to be known, justifiably, as the Fight of the Century. For 15 rounds the two undefeated heavyweights battled at a furious pace, with each man sustaining tremendous punishment. In the end Frazier prevailed, dropping Ali in the final round with a tremendous left hook to seal a unanimous decision and hand The Greatest his first loss in 32 professional fights.
Ali poses with the fight poster for his upcoming fight against Jimmy Ellis during a photo shoot in July 1971. Ellis was an old friend of Ali's — both were trained by Angelo Dundee — and knew his fighting style well from many rounds of sparring.
For those sportswriters lucky enough to cover Ali on a regular basis, each day brought surprises and, more often than not, plenty of laughs. of Trainer Drew Bundini Brown helps Ali train for his fight against Ellis. Ali won the bout by technical knockout in the 12th round to claim the vacant NABF heavyweight title.
The man in the mirror stares back as Ali examines himself while training for a fight in 1972. He won all six of his fights that year.
The Louisville Lip stands next to George Foreman before Ali's fight versus Jerry Quarry in June 1972. Ali won by technical knockout in the seventh round. Foreman at the time was 36-0. Ali would not get his shot against Foreman for more than two years.

Ali and Joe Frazier fight on the set of The Dick Cavett Show while reviewing their 1971 bout in advance of their 1974 rematch. Ali called Frazier ignorant, to which Frazier took exception. As the studio crew tried to calm Frazier down, Ali held Frazier by the neck, forcing him to sit down and sparking a fight. The television set fight amped up anticipation of their January 1974 bout.
Exploring a different side of the sport, Ali broadcasts the fight between George Foreman and Ken Norton in March 1974. Foreman won the fight by technical knockout in the second round, setting up the showdown with Ali in Zaire.
Ali jumps rope at the Salle de Congres in Kinshasa, Zaire, while training for his heavyweight title fight against George Foreman. Both Ali and Foreman spent most of the summer of 1974 training in Zaire to adjust to the climate.
While training before his fight with George Foreman, Ali kisses his mother, Odessa Clay, while his father, Cassius Clay Sr., looks on. Ali's superior strategy and ability to take a punch led him to his upset victory as he absorbed body blows from Foreman before he responded with powerful combinations to Foreman's head.
Four days before the fight, Ali holds the hand of his son Ibn in Zaire. Ali successfully courted the favor of the Zaire crowd, prompting chants of "Ali bomaye!" — translated as "Ali, kill him!"
Ali poses in front of the Le Militant statue at the presidential complex that was the site of Ali's January heavyweight title bout with Foreman. The fight was originally set for a month earlier, but Foreman suffered a cut near his eye during training, forcing a delay.
Ali stands against the railing on the River Zaire watching the sunset four days before the Rumble in the Jungle. The fight was sponsored by Zaire to achieve the $5 million purse promoter Don King had promised both Ali and Foreman.
Before employing his famous rope-a-dope strategy against Foreman, Ali makes a face at the camera. Ali allowed Foreman to throw many punches but only into his arms and body, and when Foreman tired himself out from the mostly ineffective punches, Ali took control of the fight.
Ali points before his bout with Foreman. The victory over his favored opponent made him the heavyweight champion of the world for the first time since he was stripped of his titles in 1967.
Ali stares at George Foreman during the Rumble in the Jungle. Ali earned his shot at the heavyweight title by defeating Joe Frazier in January 1974, avenging a loss three years earlier.

Ali stands with trainer Angelo Dundee, assistant trainer Wali Muhammad, physician Dr. Ferdie Pacheco and assistant trainer Drew Bundini Brown before his bout with Ron Lyle in May 1975. Ali won the fight by technical knockout in the 11th round.
Along with Don King and Joe Frazier, Ali sat for a portrait leading up to the Thrilla in Manila. Ali verbally abused Frazier during the buildup to the fight, telling the media that "it will be a killa and a thrilla and a chilla when I get the gorilla in Manila."
Ali points at the camera with Don King and his training staff behind him before the weigh-in for the Thrilla in Manila in October 1975. Philippine president Ferdinand Marcos offered to sponsor the bout and hold it in Metro Manila to divert attention from the turmoil in the country that had forced the imposition of martial law in 1972.
Wrapping up Joe Frazier proved more difficult than Ali expected, having thought Frazier would represent an easy payday and be unable to live up to his billing. The fight turned out to be a brutal affair.
Frazier faces an Ali right hook in their fight in Quezon City, Philippines. The two fighters traded vicious blows during their 14 rounds. "Man, I hit him with punches that'd bring down the walls of a city," Frazier said. Ali withstood the blows to win by TKO in the 15th round.
The third fight between Ali and Frazier, Ali won the bruising battle between the two powerful punching heavyweights when Frazier's trainer, Eddie Futch, stopped the fight before the 15th round.
A back and forth exchange, Ali controlled the early rounds of the Thrilla in Manila before Frazier fought back with powerful hooks. Ali finished strong, regaining momentum in the later rounds.

Ali makes a face during his fight with Earnie Shavers in 1977 at Madison Square Garden. Hurt badly by Shavers in the second round, Ali rebounded and outboxed Shavers throughout to build a lead on points before Shavers came on again in the later rounds. Seemingly exhausted going into the 15th and final round, Ali remained victorious by producing a closing flurry that left Shavers wobbling at the bell and the Garden crowd once again in delirium over his Ali magic.
Ali squares off with Leon Spinks at the Las Vegas Hilton Hotel in February 1978. Spinks won the fight in a split decision, ending Ali's 3.5-year reign as the heavyweight champion. It was the only time in Ali's career that he lost his championship title in the ring.
