On December 1, 1955, seamstress and civil rights activist Rosa Parks refused a city bus driver's orders to give up her seat for a white passenger. Although her action was not the first of its kind, it became the trigger for the Montgomery Bus Boycott and Mrs. Parks became an international symbol of resistance to racial segregation. You can check out books and movies about this pivotal event in the history of the United States at the Milwaukee Public Library. The picture above is a diagram of where Mrs. Parks sat on board the Cleveland Avenue bus on Thursday, December 1, 1955.
