The form of resistance that focused on civil disobedience as a means to challenge social injustices was the American Civil Rights Movement. Leaders like Martin Luther King Jr. advocated for nonviolent protests to combat racial discrimination and segregation. This approach included actions such as boycotts, sit-ins, and peaceful marches, emphasizing the moral imperative to confront injustice. Civil disobedience became a powerful tool in raising awareness and mobilizing public support for civil rights legislation, leading to significant legal and social changes in the United States.
