After Rosa Parks was arrested in Montgomery for refusing to surrender her bus seat to a white passenger, community activists asked Martin Luther King Jr. to host a meeting at his church to plan a bus boycott. He agreed, and the success of the one-day boycott led black leaders to extend the action. King was chosen to lead the Montgomery Improvement Association, formed to run the boycott, which lasted 381 days. King and other association members were arrested, and his home was bombed. The U.S. Supreme Court ruled segregation on Montgomery buses unconstitutional, and on December 21, 1956, King was one of the first passengers to board an integrated bus. The boycott made him a national leader of the civil rights movement, and his account of it, “Stride Toward Freedom,” was published in 1958. In 1957, he became president of the Southern Christian Leadership Conference, headquartered in Atlanta, and in 1960 he moved there to be more involved in its campaigns, with leadership focused on non-violent protest. In August 1963, the March on Washington for Jobs and Freedom drew 250,000 people, and he delivered his “I Have a Dream” speech. In 1964, he received the Nobel Peace Prize in Oslo, Norway, and Congress passed the Civil Rights Act of 1964, outlawing segregation in public facilities. In 1965, he and the Southern Christian Leadership Conference campaigned for black voting rights in Selma, Alabama, helping lead to the Voting Rights Act of 1965, which abolished legal impediments to voting rights for minorities and created federal protection at the polls. In response to urban riots in northern cities, he and the conference campaigned in Chicago in 1965-66, focusing on employment, housing, and education. His last campaign with the conference organized a Poor Peoples March to Washington, but he was assassinated on April 4, 1968, in Memphis, Tennessee, where he was supporting striking sanitation workers.
