Seats in the front of buses in Montgomery Alabama were reserved for white people, seats in the back were for African Americans, and seats in the middle were available to African Americans only if there were few whites on the bus. When Rosa Parks left her job as a seamstress, she took a seat just behind the white section, and soon all of the available seats on the bus were filled. "When the driver noticed a white man standing, he told Parks and three other African Americans in her row to get up so the white man could sit down. When Parks did not move, the driver called the police" (Appleby 380). When news of Park's arrest reached the NAACP, they decided her case would be used to challenge segregation, which led to the Montgomery bus boycott. This boycott marked the start of a new era of the civil rights movement, and had a successful outcome. In November 1956, the Supreme Court decided the Alabama segregated bus laws were unconstitutional, thus ending the boycott.
