Muhammad Ali Biography: Muhammad Ali’s Biography Chronicles Triumphs and Trials

Muhammad Ali was born Cassius Marcellus Clay Jr. on January 17, 1942 in Louisville, Kentucky. From a young age, Ali was interested in boxing. He started training at age 12 after his bike was stolen and a police officer suggested he learn how to box.

As an amateur, Ali won six Kentucky Golden Gloves titles, two national Golden Gloves titles, and the Light Heavyweight gold medal at the 1960 Summer Olympics in Rome. His amateur record was 100 wins with 5 losses.

Ali gained national recognition for his dancing and footwork in the ring along with his unusual strategy of keeping his hands low instead of up by his face. His skill, speed, and brash personality made him an intriguing fighter to watch even at a young age.

Early Professional Career and First Title Fight

After returning home from Rome, Ali signed his first professional contract with a group of Louisville businessmen and began training under Angelo Dundee. His first professional fight was on October 29, 1960 against Tunney Hunsaker, which Ali won by decision.

Over the next three years, Ali quickly rose up the heavyweight ranks with an impressive string of wins. By 1963, he had amassed a professional record of 19-0 and seemed ready to fight for the world title.

On February 25, 1964 in Miami Beach, Ali (then still Cassius Clay) fought the feared heavyweight champion Sonny Liston as a 7-1 underdog. Defying expectations, Ali won by TKO when Liston refused to answer the bell for the 7th round, making him the new heavyweight champion at just 22 years old.

Adopting a New Name and Religion

Just a few days after beating Liston for the heavyweight crown, Cassius Clay announced that he was changing his name to Muhammad Ali and joining the Nation of Islam.

This move shocked much of white America during the 1960s civil rights era. Ali faced hatred and racism, and many refused to call him by his new name. Some media even continued calling him Cassius Clay for years until eventually coming around.

Over time, attitudes began to change as Ali stood resolutely behind his new identity, offering thoughtful perspectives on race, religion, and politics beyond just boxing.

Vietnam War and Legal Fight Over Conscientious Objection

In early 1966, Ali was reclassified by Selective Service and deemed eligible for military service in Vietnam. He famously declared “I ain’t got no quarrel with them Vietcong” and applied for conscientious objector status, requesting exemption from the draft.

After a contentious legal battle that went all the way to the Supreme Court, Ali was found guilty of draft evasion, sentenced to 5 years in prison, fined $10,000, and banned from boxing for 3 years during his athletic prime.

Ali never ended up serving time in prison and did not fight professionally from March 1967 to October 1970. He spoke out frequently on issues of race, war, and justice during this time but missed some of his best fighting years while awaiting resolution of his court case.

Return to Boxing and Historic Fights

Once his conviction was overturned in 1970, Ali was free to return to boxing and pick up where he left off as heavyweight champion. Over the next decade, he engaged in a series of thrilling bouts that cemented his status as one of the greatest fighters ever.

In 1971, his first fight back was against Jerry Quarry, winning by TKO in the 3rd round. This set up one of the most famous fights in boxing history, Ali vs. Frazier I on March 8, 1971 at Madison Square Garden.

The Rivalry: Ali vs. Joe Frazier

Fight 2January 28, 1974Ali wins by unanimous decision
Fight 3October 1, 1975Ali wins by TKO 14th round

The first Frazier fight was vicious one with punches hammering both ways. Frazier knocked Ali down in the final round to seal the win. But Ali adjusted his tactics and came back to decisively beat Frazier twice over the next four years.

In 1974, Ali had another legendary bout against the younger, fearsome champion George Foreman in Zaire, Africa—the famous “Rumble in the Jungle” match. Ali utilized his “rope-a-dope” strategy absorbing punishment against the ropes in early rounds before fighting back to knock out Foreman in the 8th round for the world title.

Later Career and Retirement from Boxing

Even as Ali aged in the late 1970s, he summoned enough of his old magic for thrilling fights like the brutal third matchup against Frazier dubbed “The Thrilla in Manilla” in 1975. But the many blows absorbed over so many years took an undeniable physical toll.

Ali’s last win came against Leon Spinks in 1978 to regain the heavyweight title for an unprecedented third time. He retired briefly in 1979 before returning for two final losses against Larry Holmes and Trevor Berbick. He retired permanently in 1981 and focused on Parkinson’s treatment and humanitarian work.
