Besides his famous speech “I Have a Dream”, Martin Luther King is still well known for his work of nonviolent movements for black people. In 1955, Martin Luther King won national recognition for his non-violent methods used in a bus boycott in Alabama. Under his guidance, this peaceful boycott changed the law which required black people to ride in the backs of buses. After his success, Dr. King used the same way in efforts to change other discriminatory laws.

Dr. King urged Blacks to use nonviolent sit-ins, marches, demonstrations, and freedom rides in their efforts to gain full freedom and equalities. Arrested for breaking discriminatory laws, Dr. King went to jails dozens of times. He became a symbol around the world for people to protest peacefully against unjust laws. In memory of his work for peaceful changes, Dr. King received the 1964 Nobel Peace Prize, but his leadership was challenged as civil rights activists became more militant. In the late 1960s, he showed further opposition to the war in Vietnam and to economic discrimination. While planning a multiracial Poor People’s March for anti-poverty legislation, he was shot and killed in Tennessee.
