On this day in 1955, civil rights activist Rosa Parks rejected a bus driver's order to relinquish her seat to a white passenger in Montgomery, Alabama. Although the NAACP bailed her out of jail, both Parks and her husband lost their jobs.

Parks was not the first person to resist bus segregation, nor was it the first time she herself refused to accommodate the bus laws. As early as 1943, Parks exited the bus rather than to give up her seat and continue riding. Parks said "My resisting being mistreated on the bus did not begin with that particular arrest. I did a lot of walking in Montgomery."

The National Association for the Advancement of Colored People (NAACP), for whom Parks worked as a secretary, believed that she was the best candidate for seeing through a court challenge because she was perceived as a responsible, mature woman with a good reputation. Accordingly, the NAACP bailed her out of jail after her arrest.

Due to economic sanctions used against activists, Parks lost her job at the department store, and her husband quit his job after his boss forbade him to talk about his wife or her legal case. Parks was convicted in a local trial within a week of her arrest, and the appeals process was greatly slowed by the state government of Alabama. From the economic pressure of the Montgomery Bus Boycott, eventually the city conceded and reversed its segregation bus laws.
