Malcolm X was famous for being considered by some as a defender of the rights of African-Americans and by others a man full of controversies and encouraging of violence.
However, his life was short, because he was killed just before starting a speech of the many that had made him famous. The declared author of his murderer was Thomas Hagan, who was a radical member of the Nation of Islam, a movement to which Malcolm once belonged and which preached black redemption through conversion to the Muslim religion and the defense of the civil rights of Afro-descendants.
