Clay upsets Liston and renames himself
In February 1964 in Miami Beach, 22-year-old Cassius Clay, a 7-to-1 underdog, beat heavyweight champion Sonny Liston when Liston quit on his stool after six rounds. Within days Clay confirmed he belonged to the Nation of Islam, and Elijah Muhammad soon gave him the name Muhammad Ali. Much of the press, and later Floyd Patterson, kept calling him 'Clay.' The 1965 rematch in Lewiston, Maine, ended in the first round on a 'phantom punch' many never saw, and fixed the fight over his name as a national argument about who controls a Black man's identity.
