February 21, 1965: In New York City, Malcolm X, an African American nationalist and religious leader, is assassinated by rival Black Muslims while addressing his Organization of Afro-American Unity at the Audubon Ballroom in Washington Heights.Born Malcolm Little in Omaha, Nebraska, in 1925, Malcolm was the son of James Earl Little, a Baptist preacher who advocated the black nationalist ideals of Marcus Garvey.
Threats from the Ku Klux Klan forced the family to move to Lansing, Michigan, where his father continued to preach his controversial sermons despite continuing threats.
In 1937, Malcolm was taken from his family by welfare caseworkers.
By the time he reached high school age, he had dropped out of school and moved to Boston, where he became increasingly involved in criminal activities.In 1946, at the age of 21, Malcolm was sent to prison on a burglary conviction.
It was there he encountered the teachings of Elijah Muhammad, the leader of the Nation of Islam, whose members are popularly known as Black Muslims.
The Nation of Islam advocated black nationalism and racial separatism and condemned Americans of European descent as immoral “devils.” Muhammad’s teachings had a strong effect on Malcolm, who entered into an intense program of self-education and took the last name “X” to symbolize his stolen African identity.After six years, Malcolm was released from prison and became a loyal and effective minister of the Nation of Islam in Harlem, New York.
