Malcolm X (1925 - 1965) was a black leader who, as a key spokesman for the Nation of Islam, epitomized the "Black Power" philosophy. By the early 1960s, he had grown frustrated with the non-violent, integrated struggle for civil rights and worried that blacks would ultimately lose control of their own movement. In February 1965, he was killed by members of the Nation of Islam; Malcolm had recently left the organization. But even in death, his teachings lived on in the rhetoric of other black power organizations including the Black Panther Party.
