Rosa Parks was an African American civil rights activist who refused to give up her bus seat to a white person in Montgomery, Alabama.
Her act of defiance sparked the Montgomery Bus Boycott, one of the largest and most successful mass protests against racial segregation in the United States.
The boycott lasted for over a year, during which time Parks became a symbol of the civil rights movement.
Her actions helped to bring about the desegregation of public transportation in Montgomery and other cities across the country.
Parks was arrested and fined for her actions, but she continued to fight for civil rights throughout her life. In later years, she worked with the NAACP and other organizations to promote voting rights and other causes. Parks was awarded the Presidential Medal of Freedom and the Congressional Gold Medal, among other honors. She is widely considered to be one of the most important figures in American history for helping advance racial equality through activism and advocacy for social justice.
