The Montgomery Bus Boycott begins in early December of 1955, and is organized by the Women's Political Council. Rosa Parks, a long-time organizer, agrees to be the test case by repeating the actions of Claudette Colvin, who had also refused to give up her seat on a city bus to a white man. Parks is arrested, and a boycott is called for by organizers.
Police officers use horses, dogs, hoses, tear gas, and cattle prods to try and stop the demonstrations. After 381 days of Black folk boycotting the buses, the bus companies relent and end racial segregation on their buses.
