The movement that sought to promote civil rights and fight against racial segregation in the U.S. was the Civil Rights Movement. This social and political movement, primarily during the 1950s and 1960s, aimed to end racial discrimination and secure equal rights for African Americans. Key events, such as the Montgomery Bus Boycott, the March on Washington, and the Freedom Summer, highlighted the struggle against segregation and inequality. Prominent leaders such as Martin Luther King Jr., Rosa Parks, and Malcolm X were instrumental in advocating for change. The movement led to significant legislative achievements, including the Civil Rights Act of 1964 and the Voting Rights Act of 1965, transforming American society.
