Rosa Parks was a black woman who refused to give up her seat to a white passenger on a segregated bus in 1955 in Montgomery, Alabama. Her act of defiance sparked the Montgomery Bus Boycott, a 381-day protest of the city's bus system that ended segregation on public buses. Parks was arrested for her actions but came to symbolize the Civil Rights Movement. The boycott led the city to change its laws and integrate buses, marking a major victory for equality and the improving rights of black people.
