Muhammad Ali; born Cassius Marcellus Clay, Jr., January 17, 1942 – June 3, 2016, was an American professional boxer, widely regarded as one of the greatest and most significant sporting figures in history. From early in his career, Ali was known as an inspiring, controversial and polarizing figure both inside and outside the ring.
 
Clay was born in Louisville, Kentucky, and began training when he was 12 years old. At 22, he won the world heavyweight championship from Sonny Liston in an upset in 1964. Shortly after that, Clay converted to Islam, changed his "slave" name to Ali, and gave a message of racial pride for African Americans and resistance to white domination during the 1960s Civil Rights Movement.
 
In 1966, two years after winning the heavyweight title, Ali further antagonized the white establishment by refusing to be conscripted into the U.S. military, citing his religious beliefs and opposition to American involvement in the Vietnam War. He was eventually arrested, found guilty of draft evasion charges and stripped of his boxing titles. He successfully appealed in the U.S. Supreme Court, which overturned his conviction in 1971. By that time, he had not fought for nearly four years—losing a period of peak performance as an athlete. Ali's actions as a conscientious objector to the war made him an icon for the larger counterculture generation.
 
Ali remains the only three-time lineal world heavyweight champion; he won the title in 1964, 1974, and 1978. Between February 25, 1964, and September 19, 1964, Ali reigned as the heavyweight boxing champion. Nicknamed "The Greatest", he was involved in several historic boxing matches. Notable among these were the first Liston fight, three with rival Joe Frazier, and "The Rumble in the Jungle" with George Foreman, in which he regained titles he had been stripped of seven years earlier. Ali retired from boxing in 1981.
 
At a time when most fighters let their managers do the talking, Ali, inspired by professional wrestler "Gorgeous George" Wagner, thrived in—and indeed craved—the spotlight, where he was often provocative and outlandish
 
Early career
Clay made his professional debut on October 29, 1960, winning a six-round decision over Tunney Hunsaker. From then until the end of 1963, Clay amassed a record of 19–0 with 15 wins by knockout. He defeated boxers including Tony Esperti, Jim Robinson, Donnie Fleeman, Alonzo Johnson, George Logan, Willi Besmanoff, Lamar Clark, Doug Jones and Henry Cooper. Clay also beat his former trainer and veteran boxer Archie Moore in a 1962 match.
 
These early fights were not without trials. Clay was knocked down both by Sonny Banks and Cooper. In the Cooper fight, Clay was floored by a left hook at the end of round four and was saved by the bell. The fight with Doug Jones on March 13, 1963, was Clay's toughest fight during this stretch. The number-two and -three heavyweight contenders respectively, Clay and Jones fought on Jones' home turf at New York's Madison Square Garden. Jones staggered Clay in the first round, and the unanimous decision for Clay was greeted by boos and a rain of debris thrown into the ring (watching on closed-circuit TV, heavyweight champ Sonny Liston quipped that if he fought Clay he might get locked up for murder). The fight was later named "Fight of the Year".
 
In each of these fights, Clay vocally belittled his opponents and vaunted his abilities. Jones was "an ugly little man" and Cooper was a "bum". He was embarrassed to get in the ring with Alex Miteff. Madison Square Garden was "too small for me". Clay's behavior provoked the ire of many boxing fans.
 
After Clay left Moore's camp in 1960, partially due to Clay's refusing to do chores such as dish-washing and sweeping, he hired Angelo Dundee, whom he had met in February 1957 during Ali's amateur career,[34] to be his trainer. Around this time, Clay sought longtime idol Sugar Ray Robinson to be his manager, but was rebuffed.
 
Heavyweight champion
 
By late 1963, Clay had become the top contender for Sonny Liston's title. The fight was set for February 25, 1964, in Miami Beach. Liston was an intimidating personality, a dominating fighter with a criminal past and ties to the mob. Based on Clay's uninspired performance against Jones and Cooper in his previous two fights, and Liston's destruction of former heavyweight champion Floyd Patterson in two first-round knock outs, Clay was a 7–1 underdog. Despite this, Clay taunted Liston during the pre-fight buildup, dubbing him "the big ugly bear". "Liston even smells like a bear", Clay said. "After I beat him I'm going to donate him to the zoo. Clay turned the pre-fight weigh-in into a circus, shouting at Liston that "someone is going to die at ringside tonight". Clay's pulse rate was measured at 120, more than double his normal 54. Many of those in attendance thought Clay's behavior stemmed from fear, and some commentators wondered if he would show up for the bout.
 
The outcome of the fight was a major upset. At the opening bell, Liston rushed at Clay, seemingly angry and looking for a quick knockout, but Clay's superior speed and mobility enabled him to elude Liston, making the champion miss and look awkward. At the end of the first round Clay opened up his attack and hit Liston repeatedly with jabs. Liston fought better in round two, but at the beginning of the third round Clay hit Liston with a combination that buckled his knees and opened a cut under his left eye. This was the first time Liston had ever been cut. At the end of round four, as Clay returned to his corner, he began experiencing blinding pain in his eyes and asked his trainer Angelo Dundee to cut off his gloves. Dundee refused. It has been speculated that the problem was due to ointment used to seal Liston's cuts, perhaps deliberately applied by his corner to his gloves. Though unconfirmed, Bert Sugar claimed that two of Liston's opponents also complained about their eyes "burning".
 
Despite Liston's attempts to knock out a blinded Clay, Clay was able to survive the fifth round until sweat and tears rinsed the irritation from his eyes. In the sixth, Clay dominated, hitting Liston repeatedly. Liston did not answer the bell for the seventh round, and Clay was declared the winner by TKO. Liston stated that the reason he quit was an injured shoulder. Following the win, a triumphant Clay rushed to the edge of the ring and, pointing to the ringside press, shouted: "Eat your words!" He added, "I am the greatest! I shook up the world. I'm the prettiest thing that ever lived."
 
In winning this fight, Clay became at age 22 the youngest boxer to take the title from a reigning heavyweight champion, though Floyd Patterson was the youngest to win the heavyweight championship at 21, during an elimination bout following Rocky Marciano's retirement. Mike Tyson broke both records in 1986 when he defeated Trevor Berbick to win the heavyweight title at age 20.
 
Soon after the Liston fight, Clay changed his name to Muhammad Ali upon converting to Islam and affiliating with the Nation of Islam. Ali then faced a rematch with Liston scheduled for May 1965 in Lewiston, Maine. It had been scheduled for Boston the previous November, but was postponed for six months due to Ali's emergency surgery for a hernia three days before. The fight was controversial. Midway through the first round, Liston was knocked down by a difficult-to-see blow the press dubbed a "phantom punch". Ali refused to retreat to a neutral corner, and referee Jersey Joe Walcott did not begin the count. Liston rose after he had been down about 20 seconds, and the fight momentarily continued. But a few seconds later Walcott stopped the match, declaring Ali the winner by knockout. The entire fight lasted less than two minutes.
 
It has since been speculated that Liston dropped to the ground purposely. Proposed motivations include threats on his life from the Nation of Islam, that he had bet against himself and that he "took a dive" to pay off debts. Slow-motion replays show that Liston was jarred by a chopping right from Ali, although it is unclear whether the blow was a genuine knock-out punch.
 
Ali defended his title against former heavyweight champion Floyd Patterson on November 22, 1965. Before the match, Ali mocked Patterson, who was widely known to call him by his former name Cassius Clay, as an "Uncle Tom", calling him "The Rabbit". Although Ali clearly had the better of Patterson, who appeared injured during the fight, the match lasted 12 rounds before being called on a technical knockout. Patterson later said he had strained his sacroiliac. Ali was criticized in the sports media for appearing to have toyed with Patterson during the fight.
 
Ali and then-WBA heavyweight champion boxer Ernie Terrell had agreed to meet for a bout in Chicago on March 29, 1966 (the WBA, one of two boxing associations, had stripped Ali of his title following his joining the Nation of Islam). But in February Ali was reclassified by the Louisville draft board as 1-A from 1-Y, and he indicated that he would refuse to serve, commenting to the press, "I ain't got nothing against no Viet Cong; no Viet Cong never called me nigger."[45] Amidst the media and public outcry over Ali's stance, the Illinois Athletic Commission refused to sanction the fight, citing technicalities.
 
Instead, Ali traveled to Canada and Europe and won championship bouts against George Chuvalo, Henry Cooper, Brian London and Karl Mildenberger.
 
Ali returned to the United States to fight Cleveland Williams in the Houston Astrodome on November 14, 1966. The bout drew a record-breaking indoor crowd of 35,460 people. Williams had once been considered among the hardest punchers in the heavyweight division, but in 1964 he had been shot at point-blank range by a Texas policeman, resulting in the loss of one kidney and 10 feet (3.0 m) of his small intestine. Ali dominated Williams, winning a third-round technical knockout in what some consider the finest performance of his career.
 
Ali fought Terrell in Houston on February 6, 1967. Terrell was billed as Ali's toughest opponent since Liston—unbeaten in five years and having defeated many of the boxers Ali had faced. Terrell was big, strong and had a three-inch reach advantage over Ali. During the lead up to the bout, Terrell repeatedly called Ali "Clay", much to Ali's annoyance (Ali called Cassius Clay his "slave name"). The two almost came to blows over the name issue in a pre-fight interview with Howard Cosell. Ali seemed intent on humiliating Terrell. "I want to torture him", he said. "A clean knockout is too good for him."The fight was close until the seventh round when Ali bloodied Terrell and almost knocked him out. In the eighth round, Ali taunted Terrell, hitting him with jabs and shouting between punches, "What's my name, Uncle Tom... what's my name?" Ali won a unanimous 15-round decision. Terrell claimed that early in the fight Ali deliberately thumbed him in the eye—forcing Terrell to fight half-blind—and then, in a clinch, rubbed the wounded eye against the ropes. Because of Ali's apparent intent to prolong the fight to inflict maximum punishment, critics described the bout as "one of the ugliest boxing fights". Tex Maule later wrote: "It was a wonderful demonstration of boxing skill and a barbarous display of cruelty." Ali denied the accusations of cruelty but, for Ali's critics, the fight provided more evidence of his arrogance.
 
After Ali's title defense against Zora Folley on March 22, he was stripped of his title due to his refusal to be drafted to army service. His boxing license was also suspended by the state of New York. He was convicted of draft evasion on June 20 and sentenced to five years in prison and a $10,000 fine. He paid a bond and remained free while the verdict was being appealed.
 
Exile and comeback
In March 1966, Ali refused to be inducted into the armed forces. He was systematically denied a boxing license in every state and stripped of his passport. As a result, he did not fight from March 1967 to October 1970—from ages 25 to almost 29—as his case worked its way through the appeals process before his conviction was overturned in 1971. During this time of inactivity, as opposition to the Vietnam War began to grow and Ali's stance gained sympathy, he spoke at colleges across the nation, criticizing the Vietnam War and advocating African American pride and racial justice.
 
On August 12, 1970, with his case still in appeal, Ali was granted a license to box by the City of Atlanta Athletic Commission, thanks to State Senator Leroy R. Johnson. Ali's first return bout was against Jerry Quarry on October 26, resulting in a win after three rounds after Quarry was cut.
 
A month earlier, a victory in federal court forced the New York State Boxing Commission to reinstate Ali's license.[49] He fought Oscar Bonavena at Madison Square Garden in December, an uninspired performance that ended in a dramatic technical knockout of Bonavena in the 15th round. The win left Ali as a top contender against heavyweight champion Joe Frazier.
 
Ali and Frazier's first fight, held at the Garden on March 8, 1971, was nicknamed the "Fight of the Century", due to the tremendous excitement surrounding a bout between two undefeated fighters, each with a legitimate claim as heavyweight champions. Veteran boxing writer John Condon called it "the greatest event I've ever worked on in my life". The bout was broadcast to 35 foreign countries; promoters granted 760 press passes.
 
Adding to the atmosphere were the considerable pre-fight theatrics and name calling. Ali portrayed Frazier as a "dumb tool of the white establishment". "Frazier is too ugly to be champ", Ali said. "Frazier is too dumb to be champ." Ali also frequently called Frazier an "Uncle Tom". Dave Wolf, who worked in Frazier's camp, recalled that, "Ali was saying 'the only people rooting for Joe Frazier are white people in suits, Alabama sheriffs, and members of the Ku Klux Klan. I'm fighting for the little man in the ghetto.' Joe was sitting there, smashing his fist into the palm of his hand, saying, 'What the fuck does he know about the ghetto?'
 
Ali began training at a farm near Reading, Pennsylvania, in 1971 and, finding the country setting to his liking, sought to develop a real training camp in the countryside. He found a five-acre site on a Pennsylvania country road in the village of Deer Lake, Pennsylvania. On this site, Ali carved out what was to become his training camp, the camp where he lived and trained for all the many fights he had from 1972 on to the end of his career in the 1980s.
 
The Monday night fight lived up to its billing. In a preview of their two other fights, a crouching, bobbing and weaving Frazier constantly pressured Ali, getting hit regularly by Ali jabs and combinations, but relentlessly attacking and scoring repeatedly, especially to Ali's body. The fight was even in the early rounds, but Ali was taking more punishment than ever in his career. On several occasions in the early rounds he played to the crowd and shook his head "no" after he was hit. In the later rounds—in what was the first appearance of the "rope-a-dope strategy"—Ali leaned against the ropes and absorbed punishment from Frazier, hoping to tire him. In the 11th round, Frazier connected with a left hook that wobbled Ali, but because it appeared that Ali might be clowning as he staggered backwards across the ring, Frazier hesitated to press his advantage, fearing an Ali counter-attack. In the final round, Frazier knocked Ali down with a vicious left hook, which referee Arthur Mercante said was as hard as a man can be hit. Ali was back on his feet in three seconds. Nevertheless, Ali lost by unanimous decision, his first professional defeat.
 
Ali's characterizations of Frazier during the lead-up to the fight cemented a personal animosity toward Ali by Frazier that lasted until Frazier's death. Frazier and his camp always considered Ali's words cruel and unfair, far beyond what was necessary to sell tickets. Shortly after the bout, in the TV studios of ABC's Wide World of Sports during a nationally televised interview with the two boxers, Frazier rose from his chair and wrestled Ali to the floor after Ali called him ignorant.
 
In the same year basketball star Wilt Chamberlain challenged Ali, and a fight was scheduled for July 26. Although the seven foot two inch tall Chamberlain had formidable physical advantages over Ali, weighing 60 pounds more and able to reach 14 inches further, Ali was able to intimidate Chamberlain into calling off the bout. This happened during a shared press conference with Chamberlain in which Ali repeatedly responded to reporters with the traditional lumberjack warning, "Timber", and said, "The tree will fall!" With these statements of confidence, Ali was able to unsettle his taller opponent into calling off the bout.
 
After the loss to Frazier, Ali fought Jerry Quarry, had a second bout with Floyd Patterson and faced Bob Foster in 1972, winning a total of six fights that year. In 1973, Ken Norton broke Ali's jaw while giving him the second loss of his career. After initially seeking retirement, Ali won a controversial decision against Norton in their second bout, leading to a rematch at Madison Square Garden on January 28, 1974, with Joe Frazier who had recently lost his title to George Foreman.
 
Ali was strong in the early rounds of the fight, and staggered Frazier in the second round. Referee Tony Perez mistakenly thought he heard the bell ending the round and stepped between the two fighters as Ali was pressing his attack, giving Frazier time to recover. However, Frazier came on in the middle rounds, snapping Ali's head in round seven and driving him to the ropes at the end of round eight. The last four rounds saw round-to-round shifts in momentum between the two fighters. Throughout most of the bout, however, Ali was able to circle away from Frazier's dangerous left hook and to tie Frazier up when he was cornered, the latter a tactic that Frazier's camp complained of bitterly. Judges awarded Ali a unanimous decision.
