Rosa Parks was a prominent figure in the civil rights movement in the United States. She is best known for her pivotal role in the Montgomery Bus Boycott in 1955. On December 1, 1955, Parks refused to give up her seat to a white passenger on a segregated bus in Montgomery, Alabama. Her act of defiance led to her arrest and sparked a citywide boycott of the bus system, organized by civil rights leaders including Martin Luther King Jr.

The Montgomery Bus Boycott lasted for 381 days and was a key moment in the civil rights movement, showcasing the power of nonviolent resistance and inspiring similar protests across the country. Parks' courageous stand against racial segregation on public transportation helped galvanize the movement for racial equality and desegregation in the United States.

Rosa Parks continued to be a lifelong activist and advocate for civil rights, working with various organizations and speaking out against social injustice. She received numerous honors and awards for her contributions to the advancement of civil rights, and she remains an iconic figure in Black history and the struggle for equality.
