Rosa Parks is often referred to as the "Mother of the Civil Rights Movement" for her pivotal role in the Montgomery Bus Boycott. In 1955, her refusal to give up her seat to a white passenger sparked a massive protest against racial segregation in public transportation. Parks' act of defiance became a symbol of the struggle for justice and equality in the United States. Her courage and commitment to civil rights have left a lasting legacy, inspiring countless activists in the fight for social justice.
