Malcolm X

Born Malcolm Little;
May 19, 1925 – February 21, 1965
(also known as El-Hajj Malik El-Shabazz)
Was an African-American Muslim minister, public speaker, and human rights activist. To his admirers, he was a courageous advocate for the rights of African Americans, a man who indicted white America in the harshest terms for its crimes against black Americans. His detractors accused him of preaching racism and violence. 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. His childhood, including his father's lessons concerning black pride and self-reliance and his own experiences concerning race, played a significant role in Malcolm X's adult life. 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 Malcolm X's departure from the organization in March 1964.

After leaving the Nation of Islam, Malcolm X became a Sunni Muslim and made a pilgrimage to Mecca. 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.
