Malcolm X (born Malcolm Little; 1925 – 1965), also known as El-Hajj Malik El-Shabazz, was an African American Muslim minister, public speaker, and human rights activist. He has been described as one of the greatest and most influential African Americans in history. Malcolm X was born in Omaha, Nebraska. By the time he was 13, his father had died and his mother had been committed to a mental hospital. After living in a series of foster homes, Malcolm X became involved in the criminal underworld in Boston and New York. In 1945, Malcolm X was sentenced to eight to ten years in prison. While in prison, Malcolm X became a member of the Nation of Islam. After his parole in 1952, he became one of the Nation's leaders and chief spokesmen. For nearly a dozen years, he was the public face of the Nation of Islam. Tension between Malcolm X and Elijah Muhammad, head of the Nation of Islam, led to his departure from the organization in March 1964. After leaving the Nation of Islam, Malcolm X made the pilgrimage, the Hajj, to Mecca and became a Sunni Muslim. He traveled extensively throughout Africa and the Middle East. He founded Muslim Mosque, Inc., a religious organization, and the secular, black nationalist Organization of Afro-American Unity. Less than a year after he left the Nation of Islam, Malcolm X was assassinated while giving a speech in New York.
