Rosa Parks’ childhood brought her early experiences with racial discrimination and activism for racial equality. Rosa earned her high school degree in 1933. She soon became actively involved in civil rights issues by joining the Montgomery chapter of the NAACP in 1943.
On December 1, 1955, after a long day's work at a Montgomery department store, where she worked as a seamstress, Rosa Parks boarded the Cleveland Avenue bus for home. As the bus Rosa was riding continued on its route, it began to fill with white passengers. The bus driver eventually demanded that Parks give up her seat, but she refused and was later arrested at the scene. Parks’ refusal to surrender her seat to a white passenger on a Montgomery, Alabama bus spurred a city-wide boycott. The combination of legal action, backed by the unrelenting determination of the African-American community, made the 381-day Montgomery Bus Boycott one of the largest and most successful mass movements against racial segregation in history.
