Malcolm X was a minister, a leader in the civil rights movement and a supporter of Black nationalism. He urged his fellow Black Americans to protect themselves against white aggression “by any means necessary,” a stance that often put him at odds with the nonviolent teachings of Martin Luther King, Jr. His charisma and oratory skills helped him achieve national prominence in the Nation of Islam, a belief system that merged Islam with Black nationalism. After Malcolm X’s assassination in 1965, his bestselling book, The Autobiography of Malcolm X, popularized his ideas and inspired the Black Power movement.
