On December 1, Rosa Parks refuses to relinquish her seat on a Montgomery city bus to a white passenger. She is arrested for violating municipal laws and ordered to appear for trial four days later. She is convicted and ordered to pay a fine of $10. When she refuses to pay, she is jailed.

On the 5th, the Montgomery Bus Boycott begins, inspired by Rosa Parks and led by Martin Luther King, Jr. It continues through 1956. The boycott gives King a position of leadership within the national civil rights movement and demonstrates that nonviolent methods of protest could be effective.
