In December 2015, the United States celebrated the 60th anniversary of the Montgomery Bus Boycott. The boycott began when Rosa Parks refused to give up her seat on a public bus. She was arrested for her actions on December 1, 1955. Civil rights supporters refused to use the public bus system in Montgomery, Alabama, for over a year. They forced the bus company to change its rules. For her part in the change, Parks is called the “Mother of the Civil Rights Movement.” Celebrations for the anniversary were planned throughout the nation.
