Rosa Parks is a pivotal symbol of the Civil Rights Movement in American history. Her refusal to give up her bus seat to a white passenger in Montgomery, Alabama, on December 1, 1955, ignited a city-wide boycott led by Martin Luther King Jr. and sparked broader national efforts to end racial segregation. Parks' act of defiance became a powerful representation of resistance against systemic racism and injustice, highlighting the struggle for civil rights among African Americans. Her legacy continues to inspire movements advocating for equality and social justice worldwide.
