(Montgomery, Ala.) NAACP member Rosa Parks refuses to give up her seat at the front of the "coloured section" of a bus to a white passenger, defying a southern custom of the time. In response to her arrest the Montgomery black community launches a bus boycott, which will last for more than a year, until the buses are desegregated Dec. 21, 1956. As newly elected president of the Montgomery Improvement Association (MIA), Reverend Martin Luther King, Jr., is instrumental in leading the boycott.
