Rosa Parks' life was marked by seminal events that solidified her place in history. Her refusal to give up her seat on a segregated bus in Montgomery, Alabama, on December 1, 1955, became a powerful symbol of resistance against racial injustice. This act of defiance sparked the Montgomery Bus Boycott and propelled her into the forefront of the American civil rights movement. Parks' commitment to nonviolent activism and her role as a secretary for the NAACP contributed to her significance in advocating for racial equality. Her legacy continues to inspire generations of activists.
