Rosa Louise McCauley stood for equality and the end to racial segregation. At age 19, Rosa met and married Raymond Parks. She soon became actively involved in civil rights issues by joining the Montgomery chapter of the National Association for the Advancement of Colored People or NAACP. On December 1, 1955, she quietly refused to give up her seat to a white passenger on a segregated bus in Montgomery, Alabama. She was arrested and her steadfast action sparked a 381-day bus boycott. The law was changed to stop segregating people based on the color of their skin. Rosa Parks bravely became a leader of the Civil Rights movement throughout her lifetime with the determination that all people should be treated equally and with dignity.
