Rosa Parks is the famous civil rights figure known for her pivotal role in the Montgomery Bus Boycott in 1955. By refusing to give up her seat to a white passenger on a segregated bus, Parks sparked a significant movement against racial segregation. Her arrest prompted African Americans in Montgomery, Alabama, to organize a boycott of the bus system, lasting over a year and demonstrating their strength and solidarity. This event became a catalyst for the civil rights movement, leading to increased activism and the eventual desegregation of public transportation. Parks’ courageous act remains a symbol of resistance and the fight for equality.
