Cassius Clay was already the Heavyweight Champion of the World – having defeated Sonny Liston a little less than 2 weeks earlier – when he announced his conversion to the Nation of Islam (more widely known as the Black Muslims). With that, of course, came the change of name: Muhammad meaning ‘one who is worthy of praise’ Ali ‘fourth rightly guided caliph’.
Clay’s conversion was, to say the least, controversial. Many journalists refused to use his new name at first, and given Clay’s history of courting publicity, the name change was widely seen as a stunt. However, Ali’s conversion was quite sincere – although in 1975 he changed faiths to Sunni Islam – and he retains the name even today.
