Muhammad Ali (born Cassius Marcellus Clay, Jr. on January 17, 1942) is a retired American boxer. In 1999, Ali was crowned "Sportsman of the Century" by Sports Illustrated. He won the World Heavyweight Boxing championship three times, and won the North American Boxing Federation championship as well as an Olympic gold medal.
Ali was born in Louisville, Kentucky. He was named after his father, Cassius Marcellus Clay, Sr., who was named for the 19th century abolitionist and politician Cassius Clay. Ali later changed his name after joining the Nation of Islam and subsequently converted to Sunni Islam in 1975.
Following his ascension to champion, he famously revealed that he was a member of the Nation of Islam (often called the Black Muslims at the time) and Malcolm X provided Clay with the name Cassius X, discarding his surname as a symbol of his ancestors' enslavement, as had been done by other Nation members. On Friday, March 6, 1964, Malcolm X took Clay on a guided tour of the United Nations building (for a second time). Malcolm X announced that Clay would be granted his "X." That same night, Elijah Muhammad recorded a statement over the phone to be played over the radio that Clay would be renamed Muhammad (one who is worthy of praise) Ali (fourth rightly guided caliph). Only a few journalists (most notably Howard Cosell) accepted it at that time. The adoption of this name symbolized his new identity as a member of the Nation of Islam.
In 1964, Ali failed the Armed Forces qualifying test because his writing and spelling skills were subpar. However, in early 1966, the tests were revised and Ali was reclassified 1A. He refused to serve in the United States Army during the Vietnam War as a conscientious objector, because "War is against the teachings of the Holy Qur'an. I'm not trying to dodge the draft. We are not supposed to take part in no wars unless declared by Allah or The Messenger. We don't take part in Christian wars or wars of any unbelievers." Ali also famously said, "I ain't got no quarrel with those Vietcong" and "no Vietcong ever called me nigger."Ali refused to respond to his name being read out as Cassius Clay, stating, as instructed by his mentors from the Nation of Islam, that Clay was the name given to his slave ancestors by the white man. By refusing to respond to this name, Ali's personal life was filled with controversy. Ali was essentially banned from fighting in the United States and forced to accept bouts abroad for most of 1966.
Ali's actions in refusing military service and aligning himself with the Nation of Islam made him a lightning rod for controversy, turning the outspoken but popular former champion into one of that era's most recognizable and controversial figures. Appearing at rallies with Nation of Islam leader Elijah Muhammad and declaring his allegiance to him at a time when mainstream America viewed them with suspicion — if not outright hostility — made Ali a target of outrage, and suspicion as well. Ali seemed at times to even provoke such reactions, with viewpoints that wavered from support for civil rights to outright support of separatism. For example, Ali once stated, in relation to integration:" No intelligent black man or black woman in his or her right black mind wants white boys and white girls coming to their homes to marry their black sons and daughters."
Ali converted from the Nation of Islam to Sect Sunni Islam in 1975. In a 2004 autobiography, written with daughter Hana Yasmeen Ali, Muhammad Ali attributes his conversion to the shift towards Sunni Islam made by W.D. Muhammad after he gained control of the Nation of Islam upon the death of his father, Elijah Muhammad in 1975.
