Civil Rights icon Rosa Parks was 42 years old when she was arrested on December 1, 1955, just a few weeks shy of her February 4 birthday. While riding on a segregated public bus in Montgomery, Alabama, Mrs. Parks was seated directly behind the front section designated for white passengers; that section filled up, and when a bus driver ordered Mrs. Parks to move to allow a white passenger to take her seat, she refused. She was arrested for this action, which violated a Montgomery city law that enforced the practice of racial segregation on public transportation.
