There are at least two important impacts of this social movement on our society.
First, the movement changed race relations in the United States forever. Someone living 50 years ago would surely never have imagined that a President of the United States would be part-African American in their lifetime. It is hard to overstate how much our race relations have changed.
Second, the whole ethos of the Civil Rights Movement has changed America for other groups. It encouraged people to think in terms of their rights as members of groups. It helped to create or accelerate movements for women’s rights and Hispanic rights, among others. It also helped to put civil disobedience “on the map” as a tactic to be used by many other groups.
