Muhammad Ali won Olympic gold as Cassius Clay, took the heavyweight championship at twenty-two, and then gave up the prime of his career rather than be inducted into the Army during the Vietnam War. Convicted of draft evasion and barred from the ring, he was vindicated by the Supreme Court in 1971 and went on to win the heavyweight title twice more, becoming one of the most recognized people in the world and a lasting symbol of Black self-assertion and religious conscience.

Early Life
Cassius Marcellus Clay Jr. was born on 17 January 1942 in Louisville, Kentucky, the son of Cassius Marcellus Clay Sr. and Odessa Grady Clay, who raised him in the Baptist church. He grew up in segregated Louisville. According to the familiar account, he took up boxing at twelve after his bicycle was stolen and he told Joe Martin, who ran a local boxing program, that he wanted to fight the thief; Martin became his first trainer.
As an amateur he compiled a record of about 100 wins and 8 losses and won two national Golden Gloves titles and two Amateur Athletic Union national titles. In September 1960, at eighteen, he won the gold medal in the light heavyweight division at the Olympic Games in Rome. He turned professional on his return and became known as much for his speed, footwork, and brash rhyming predictions as for his punching.
Life and Work
On 25 February 1964, at the Convention Hall in Miami Beach, Clay faced the heavyweight champion Sonny Liston as a seven-to-one underdog. Liston did not come out for the seventh round, and Clay became world heavyweight champion at twenty-two. Days later he confirmed that he had joined the Nation of Islam, whose meetings he had attended since the early 1960s and where he had come to know Malcolm X. On 6 March 1964 Elijah Muhammad gave him the name Muhammad Ali.
In February 1966 the Selective Service notified Ali that he was eligible for the draft. He applied for exemption as a conscientious objector on religious grounds, and a hearing officer, retired judge Lawrence Grauman, found his objection sincere and recommended that it be granted. The Department of Justice advised against the claim, and the appeal board denied it without stating reasons. On 28 April 1967, at the induction center in Houston, Ali refused to step forward when his name was called. Within hours the New York State Athletic Commission suspended his boxing license and withdrew recognition of his title, and other commissions followed. On 20 June 1967 a federal jury in Houston convicted him after deliberating twenty-one minutes; Judge Joe Ingraham sentenced him to five years in prison and a $10,000 fine. Free on appeal but stripped of his passport and his ability to box in the United States, Ali spent three and a half years out of the ring, a period in which he spoke publicly against the war and in defense of his faith.
After forty-three months away, Ali returned to the ring on 26 October 1970. On 8 March 1971, at Madison Square Garden, he lost to the undefeated champion Joe Frazier by unanimous decision in a bout promoted as the Fight of the Century. On 28 June 1971 the Supreme Court reversed his conviction in Clay v. United States. In an 8–0 per curiam decision, with Justice Thurgood Marshall not participating because of his earlier involvement in the case at the Justice Department, the Court held that because the appeal board had given no reason for its denial, and the Justice Department had advised it on grounds that were legally wrong, the conviction could not stand.
On 30 October 1974, in Kinshasa, Zaire, Ali regained the heavyweight title from George Foreman, absorbing Foreman’s punches on the ropes for much of the fight before knocking him out in the eighth round. He lost the title to Leon Spinks by split decision on 15 February 1978 and won it back from Spinks in a unanimous decision on 15 September 1978 at the Louisiana Superdome in New Orleans, becoming the first boxer to win the heavyweight championship three times. He defended the title against Frazier in the “Thrilla in Manila” in 1975 and fought until 1981, retiring with a professional record of 56 wins and 5 losses.
Ali’s religious life continued to change. He made the hajj to Mecca in 1972, and on 25 February 1975, after the death of Elijah Muhammad, he embraced Sunni Islam. In later decades he spoke publicly against violence committed in Islam’s name.
Legacy
In 1984 Ali was diagnosed with Parkinson’s syndrome, which progressively limited his speech and movement. He remained a public figure through humanitarian work, and at the 1996 Olympic Games in Atlanta he lit the Olympic cauldron. In 2005 President George W. Bush awarded him the Presidential Medal of Freedom, and the same year the Muhammad Ali Center, a museum and cultural center, opened in Louisville. He died in Scottsdale, Arizona, on 3 June 2016, at the age of seventy-four.
Ali’s significance extends well beyond his record. His refusal of induction, at the cost of his title and income, made him the most prominent American of his generation to oppose the Vietnam War on grounds of conscience, and his insistence on his chosen name and faith challenged the expectation that Black athletes remain deferential. Denounced by many Americans in the late 1960s, he was honored by a Republican president and embraced worldwide by the end of his life. The National Archives holds records of his draft case, FBI files on his activities, and photographs of him at the White House with five presidents.
