Rosa Parks was an iconic figure in the American civil rights movement, best known for her courageous act of refusing to give up her bus seat to a white passenger in Montgomery, Alabama on December 1, 1955. This act of defiance sparked the Montgomery Bus Boycott, a pivotal event that helped to challenge racial segregation in the United States. Parks' bravery and commitment to justice made her a symbol of the struggle for civil rights. She worked alongside prominent leaders like Martin Luther King Jr. and continued to advocate for equality throughout her life, inspiring generations to fight against injustice and discrimination.
