Rosa Parks was a prominent civil rights activist known for her leadership in the NAACP. She became an iconic figure after refusing to give up her bus seat to a white passenger in Montgomery, Alabama, in 1955. This act of defiance sparked the Montgomery Bus Boycott, a pivotal event in the Civil Rights Movement that led to the eventual desegregation of public transportation. Parks' courage and commitment to justice made her a symbol of the struggle against racial inequality and an enduring inspiration for activists seeking social change.
