The primary achievement of the Civil Rights Movement in the United States was the successful fight against racial segregation and discrimination, leading to significant legislative and societal changes. Key milestones included the passage of the Civil Rights Act of 1964 and the Voting Rights Act of 1965, which legally enforced equality and aimed to eliminate barriers to voting for African Americans. This movement galvanized public awareness and activism, inspired various social justice movements, and laid the groundwork for ongoing efforts toward achieving racial equality and justice, shaping the trajectory of American civil rights.
