Muhammad Ali And Leon Spinks Boxing At Superdome

On September 15, 1978, boxer Muhammad Ali defeats Leon Spinks at the Louisiana Superdome in New Orleans to win the world heavyweight boxing title for the third time in his career, the first fighter ever to do so. Following his victory, Ali retired from boxing, only to make a brief comeback two years later. Ali, who once claimed he could “float like a butterfly, sting like a bee,” left the sport permanently in 1981.

Born Cassius Marcellus Clay Jr. in Louisville, Kentucky, on January 14, 1942, the future world champ changed his name to Muhammad Ali in 1964 after converting to Islam. He earned a gold medal at the 1960 Olympic Games in Rome and made his professional boxing debut against Tunney Hunsaker in October 1960, winning the bout in six rounds. On February 25, 1964, Ali defeated the heavily favored Sonny Liston in six rounds to become heavyweight champ, after which he famously declared, “I am the greatest!”

Muhammad Ali

In 1954, a boy from Kentucky had his bicycle stolen. Seeing him angry, a police officer suggested that in order to beat the thief, he'd better learn how to fight. Specifically: how to box.

During the Vietnam War, Ali refused to be inducted into the U.S. armed forces and in 1967 was convicted of draft evasion and banned from boxing for three years. He stayed out of prison as his case was appealed and returned to the ring in October 1970, knocking out Jerry Quarry in Atlanta in the third round. On March 8, 1971, Ali fought Joe Frazier in the “Fight of the Century” and lost after 15 rounds, the first loss of his professional boxing career. In June 1971, the U.S. Supreme Court overturned Ali’s conviction for evading the draft.

At a January 1974 rematch at New York City’s Madison Square Garden, Ali defeated Frazier in 12 rounds. In October of that same year, an underdog Ali bested George Foreman and reclaimed his heavyweight champion belt at the heavily hyped “Rumble in the Jungle” in Kinshasa, Zaire, with a knockout in the eighth round. On February 15, 1978, in Las Vegas, an aging Ali lost the title to Leon Spinks in a 15-round split decision. For Spinks, who was born in 1953 and won a gold medal in boxing at the 1976 Summer Olympics in Montreal, the fight was just the eighth of his professional career. However, seven months later, on September 15, Ali won the title back, in a unanimous 15-round decision.

In June 1979, Ali announced he was retiring from boxing. On October 2, 1980, he returned to the ring and fought heavyweight champ Larry Holmes, who knocked him out in the 11th round. After losing to Trevor Berbick on December 11, 1981, Ali left the ring for the last time, with a record of 56 wins, five losses and 37 knockouts. In 1984, he was revealed to have Parkinson’s disease. Ali died on June 3, 2016. Spinks retired from boxing in 1995 with a record of 26 wins, 17 losses and 14 knockouts. He died on February 5, 2021.
