Martin Luther King, Jr. was an American clergyman, activist, and leader in the African-American Civil Rights Movement. He is best known for his role in the advancement of civil rights using nonviolent civil disobedience. King has become a national icon in the history of American progressivism.
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. With the SCLC, King led an unsuccessful struggle against segregation in Albany, Georgia in 1962, and organized nonviolent protests in Birmingham, Alabama that attracted national attention following television news coverage of the brutal police response. King also helped to organize the 1963 March on Washington, where he delivered his "I Have a Dream" speech. There, he established his reputation as one of the greatest orators in American history. He also established his reputation as a radical, and became an object of the Federal Bureau of Investigation's COINTELPRO for the rest of his life. FBI agents investigated him for possible communist ties, recorded his extramarital liaisons and reported on them to government officials, and on one occasion, mailed King a threatening anonymous letter that he interpreted as an attempt to make him commit suicide.
