Did Rosa Parks make any contributions?

In 1955, Rosa Parks, an African American woman, chose not to give up her seat to a white man on a city bus in Montgomery, Alabama. During a time when segregation was the law, her refusal to give up her seat was seen by law enforcement as an act of civil disobedience. Rosa Parks was arrested and placed in custody. As a result of her arrest, African American citizens in Montgomery took action by organizing a boycott of the city buses. The movement gained momentum and began to attract national attention. A newcomer to Montgomery, Dr. Martin Luther King was one of the organizers of this movement.
Rosa Parks contributed to the civil rights movement by her actions or, in this case, her inaction. Her refusal to give up her seat for a white man served as a spark that ignited the movement to end segregation laws. In 1956, the Supreme Court ruled that bus segregation was unconstitutional.
