King, Martin Luther Jr. 1929 - 1968. US civil-rights campaigner. Black leader, and Baptist minister. He first came to national attention as leader of the Montgomery, Alabama, bus boycott 1955, and was one of the organizers of the march of 200,000 people on Washington DC 1963 to demand racial equality. An advocate of nonviolence, he was awarded the Nobel Peace Prize 1964. He was assassinated in Memphis, Tennessee, by James Earl Ray (1928-...). Born in Atlanta, Georgia, son of a Baptist minister, King founded the Southern Christian Leadership Conference 1957. A brilliant and moving speaker, he was the symbol of, and leading figure in, the campaign for integration and equal rights in the late 1950s and early 1960s. In the mid-1960s his moderate approach was criticized by black militants. He was the target of intensive investigation by the federal authorities, chiefly the FBI under J Edgar Hoover. His personal life was scrutinized and criticized by those opposed to his policies. King's birthday (15 Jan) is observed on the third Monday in Jan as a public holiday in the USA. James Earl Ray was convicted of the murder, but there is little evidence to suggest that he committed the crime. Various conspiracy theories concerning the FBI, the CIA, and the Mafia have been suggested.
