Pivotal social and legislative actions during the U.S. Civil Rights Movement included landmark events like the Montgomery Bus Boycott and the passage of the Civil Rights Act of 1964. Activists fought against racial segregation and discrimination, pushing for equality and justice for African Americans. Key figures such as Martin Luther King Jr. and Rosa Parks inspired mass mobilization and nonviolent protest; their efforts resulted in significant legal changes and greater public awareness of civil rights issues. The movement helped to dismantle institutional racism and laid the groundwork for future advocacy, shaping American society's trajectory towards inclusivity and equality.
