Born Malcolm Little, Malcolm X began his real education in a prison library where he was serving time for robbery. Upon his release, he joined the Nation of Islam whose leader Elijah Muhammad preached that the black race was superior to the white, that the white race was inherently evil, and that total separation was the only way to achieve racial equality. Malcolm X rose quickly through the ranks, attracting numerous converts with his fiery oratory skills, organizational abilities, and tireless work. In 1964, disturbed by Elijah Muhammad's accumulation of wealth, Malcolm X left the Nation of Islam and started his own organization, the Organization of Afro-American Unity, which vowed to promote greater harmony among all nationalities and races. He was warned repeatedly that some of his former associates were plotting to kill him, and on February 22, 1965 three men shot him to death as he gave a speech in the Harlem Ballroom.
