Rosa Parks's life was profoundly impacted by the events surrounding her pivotal act of defiance on a Montgomery bus in 1955, which became a catalyst for the civil rights movement. Her arrest for refusing to give up her seat to a white passenger symbolized the struggle against racial segregation and inspired widespread activism. Parks's involvement with the NAACP and her tireless efforts for equality underscored her commitment to justice. The subsequent Montgomery Bus Boycott not only highlighted systemic racism but also showcased the collective strength of the African American community. Parks's courage continues to inspire social justice movements today.
