Rosa Parks refuses to relinquish her seat in the "colored" section of the bus to a white passenger after the "white" section of the bus was filled. She is arrested for civil disobedience.

Rosa Parks leads a peaceful defiance that prompted the 1955 bus boycott in Montgomery, Alabama.

This clip explains the impact of the Montgomery Bus Boycott on the Civil Rights Movement as well as Rosa Parks' role in the boycott. It mentions that the story behind the boycott is more complex, as Rosa Parks wasn't first black person to resist bus segregation. Rather, there were several other women arrested for the same offense in the last 12 months, one of them being 15-year-old Claudette Colvin.
