What movement aimed to end racial discrimination in the U.S.?

The Civil Rights Movement is recognized as the pivotal movement aimed specifically at ending racial discrimination in the United States. This movement, which gained significant momentum during the 1950s and 1960s, focused on securing equal rights for African Americans and fighting against systemic racism and segregation. It brought attention to issues such as voting rights, desegregation of public facilities, and equality in education, ultimately leading to landmark legislation such as the Civil Rights Act of 1964 and the Voting Rights Act of 1965. The efforts of numerous activists and organizations during this time not only addressed the legal and social injustices faced by African Americans but also inspired future movements for equality and justice across different demographics within the United States.

The other movements mentioned, while significant in their own rights, focus on different aspects: the Labor Movement primarily aimed at achieving better working conditions and fair labor practices, the Women's Suffrage Movement sought to secure voting rights for women, and the Environmental Movement addresses ecological concerns and sustainability. Each has its distinct focus and objectives, which differ from the specific goal of combating racial discrimination that defines the Civil Rights Movement.
