Muhammad Ali, the magnificent heavyweight champion whose fast fists and irrepressible personality transcended sports and captivated the world, has died according to a statement released by his family. He was 74.
Ali had been hospitalized for a respiratory issue June 2. At the time, a rep said he was in fair condition.
One of the greatest fighters in the history of boxing, Ali retired in 1981 after losing to Trevor Berbick in his 61st career bout.
Soon thereafter, Ali -- who doctors said had begun showing signs of sluggishness and neurological damage in the 1970s -- began receiving treatment for Parkinson's disease.
Ali, who called himself "The Greatest," was married four times and had nine children, including daughter Laila, who also became a professional boxer. Ali and his fourth wife, Yolanda "Lonnie" Williams, had been married since 1986.
Legendary Liston Bouts
Born Cassius Clay on Jan. 17, 1942, Ali first stepped in the ring at age 12 in his hometown of Louisville, Ky., after his bicycle was stolen and a police officer suggested he learn how to box. Ali went on to become one of the most successful athletes and revered public figures in history.
Acclaimed for his quick, dancing style as a fighter, Ali also blended a unique mix of political activism and personal conviction that won him international recognition outside of the ring.
After winning 100 of 108 amateur fights, Ali took home an Olympic gold medal at the 1960 Summer Olympics in Rome. He later allegedly chucked the medal into a river after a waitress at a soda fountain in Louisville refused to serve him because he was black.
Weeks after the Olympics, Ali signed a lucrative contract and won his first pro bout on Oct. 29, 1960, against Tunney Hunsaker. Ali quickly ingratiated himself with the media with his boastful claims and fresh, stylish way of speaking. He told Sports Illustrated in 1961: "Most of them [other boxers] … can fight almost as good as I can. I'm just saying you never heard of them. And the reason for that is because they cannot throw the jive. Cassius Clay is a boxer who can throw the jive better than anybody."
The brash, underdog Ali promised boxing fans he'd "float like a butterfly, sting like a bee" against Sonny Liston.
At age 22, he stunned the larger Liston, beating the champ in seven rounds in Miami to win his first heavyweight title. In their next match in 1965, Ali floored Liston with a hard, quick blow minutes into the bout and retained his crown when the referee stopped the fight.
Conscientious Objector Regains Fans, Titles
With one Olympic gold medal and a heavyweight belt to his credit, Ali soon began making headlines for his religious and political beliefs.
Inspired by black rights activist Malcolm X, he converted to Islam and changed his name to Muhammad Ali in 1964. When he refused in 1967 to serve in the U.S. Army because of his religious convictions, Ali fended off sharp criticism from a nation that was raw from the dividing forces of the Vietnam War and the civil rights movement. Ali was stripped of his heavyweight title in 1967, fined $10,000 and sentenced to five years in prison for draft evasion. That conviction was overturned by the U.S. Supreme Court in 1971.
Months later, Ali went head-to-head with Joe Frazier in a legendary 15-round fight. Frazier was unanimously declared the winner of the bruising bout and succeeded Ali as heavyweight champ. Ali said of the grueling fight, "It was like death. Closest thing to dyin' that I know of."
Ali beat Frazier in their next two bouts, including a unanimous 12-round decision in 1974 that set up his heavyweight bout against George Foreman in Zaire (now Congo) 10 months later. Ali won the "Rumble in the Jungle," knocking out Foreman in the eighth round and reclaiming the world heavyweight title. The bout was chronicled in the 1996 documentary "When We Were Kings."
The outspoken champ faced Frazier one last time in an Oct. 1, 1975, bout dubbed "The Thrilla in Manila." Ali defended his title by stopping Frazier after an exhausting 15 rounds in the Philippines. The Ali-Frazier fight trilogy is generally regarded as the finest display of boxing in the history of the sport.
On Feb. 15, 1978, Ali lost his heavyweight title to Leon Spinks, but beat Spinks seven months later to reclaim the crown. He finished his career in 1981 with a record of 56 wins (including 37 by knockout) and five losses.
Ali suffered for years from Parkinson's disease, which ravaged his body but could never dim his larger-than-life presence. He was hospitalized earlier this week.
Though gone from the ring, Ali entrenched himself in charitable work and humanitarian causes -- from serving as a United Nations "Messenger of Peace" to supporting hunger and poverty relief. He appeared on the lecture circuit, although the frequency of his appearances lessened when his speech began to slur from his advancing disease.
The father of such memorable quotes as "The man who has no imagination has no wings" provided one of the lasting images of the 1996 Summer Olympics in Atlanta. Before a worldwide audience, he made a surprise appearance at the Games' opening ceremonies, where, his hand shaking from Parkinson's tremors, he took the Olympic torch and lighted the stadium cauldron. And at the London Olympics in 2012, he was again a participant in the opening ceremonies.
In 2005, he was awarded the highest U.S. civilian honor, the Presidential Medal of Freedom.
Late last year, Ali hit at Donald Trump following his proposal to temporarily ban Muslims from entering the U.S. "I am a Muslim and there is nothing Islamic about killing innocent people in Paris, San Bernardino, or anywhere else in the world," Ali said in a statement. "True Muslims know that the ruthless violence of so called Islamic Jihadists goes against the very tenets of our religion."
A towering figure in his prime, he still traveled and made appearances in his later years despite being muted by the thousands of punches he took during his remarkable career.
He beat the invincible Sonny Liston, fought a string of thrilling fights with Joe Frazier and stopped George Foreman in the "Rumble in the Jungle" in Zaire. But he paid a terrible price for the estimated 29,000 punches he took to his head during a career that made him perhaps the most recognized person in the world.
