King's rise to national and international prominence began in Montgomery, Alabama, in 1955. In that year, Rosa Parks, an African American woman, was arrested for refusing to obey a city ordinance that required African Americans to sit or stand at the back of municipal buses. The African American citizens of the city (one of the most thoroughly segregated in the South) organized a bus boycott in protest and asked King to serve as their leader. Thousands boycotted the buses for more than a year, and despite segregationist violence against them, King grounded their protests on his deeply held belief in nonviolence. In 1956, the U.S. Supreme Court ordered Montgomery to provide integrated seating on public buses.
In the following year, King and other African American ministers founded the Southern Christian Leadership Conference (SCLC) to carry forward the nonviolent struggle against segregation and legal discrimination. As protests grew, so did the unhappiness of King and his associates with the unwillingness of the president and Congress to support civil rights. The SCLC, therefore, organized massive demonstrations in Montgomery (King wrote "Letter from Birmingham Jail" during these demonstrations). With the civil rights movement now in the headlines almost every day, President Kennedy proposed to Congress a far-reaching civil rights bill.
