Rosa Parks stood up for what she believed, or rather, sat down for what she believed. On the evening of December 1, 1955, Parks, an African American, chose to take a seat on the bus on her ride home from work. Because she sat down and refused to give up her seat to a white passenger, she was arrested for disobeying an Alabama law requiring black people to relinquish seats to white people when the bus was full. (Blacks also had to sit at the back of the bus.) Her arrest sparked a 381-day boycott of the Montgomery bus system. It also led to a 1956 Supreme Court decision banning segregation on public transportation. Who was Rosa Parks, the woman who helped spark the civil rights movement of the 1960s?
