Rosa Parks spent about a day behind bars. One day after Rosa Parks was detained for refusing to give up her seat to a white man on December 1, 1955, NAACP President Edgar Nixon granted her bail, allowing her to leave jail. Four days following her arrest, the courts found her guilty of disorderly conduct.
Parks’ refusal to give up her seat served as the NAACP’s test case, sparking the Montgomery Bus Boycott that eventually resulted in the repeal of segregation laws. Three months later, on February 21, 1956, Parks was arrested once more for breaking a state law prohibiting coordinated boycotts. She was a part of the organization’s executive board of directors at the time that the Montgomery Bus Boycott was being planned.
