Martin Luther King, Jr. (January 15, 1929 - April 4, 1968) was an American clergyman, activist, and prominent leader in the African-American Civil Rights Movement. A Baptist minister, King became a civil rights activist early in his career. He led the 1955 Montgomery Bus Boycott and helped found the Southern Christian Leadership Conference in 1957, serving as its first president. King's efforts led to the 1963 March on Washington, where King delivered his "I Have a Dream" speech.
