 This was not the first time this happened — for example Parks was inspired by 15 year old Claudette Colvin doing the same thing nine months earlier — but the Parks act of civil disobedience was chosen, symbolically, as an important catalyst in the growth of the Civil Rights Movement; activists built the Montgomery Bus Boycott around it, which lasted more than a year and resulted in desegregation of the privately run buses in the city.Civil rights protests and actions, together with legal challenges, resulted in a series of legislative and court decisions which contributed to undermining the Jim Crow system.The decisive action ending segregation came when Congress in bipartisan fashion overcame Southern filibusters to pass the Civil Rights Act of 1964 and the Voting Rights Act of 1965.
