Which movement sought to end racial segregation in the United States?

The Civil Rights Movement specifically aimed to end racial segregation and discrimination against African Americans in the United States, particularly during the 1950s and 1960s. This movement sought to secure equal rights and public access for African Americans, promoting an end to the Jim Crow laws that enforced segregation in the South. Key figures such as Martin Luther King Jr., Malcolm X, and organizations like the NAACP played pivotal roles in advocating for legislative changes, such as the Civil Rights Act of 1964 and the Voting Rights Act of 1965, which were significant milestones in the fight for equality.

The other options, while important in their own contexts, did not primarily focus on racial segregation. The Labor Movement addresses workers' rights and fair labor standards, the Women's Suffrage Movement concentrated on securing voting rights for women, and the Abolitionist Movement sought to end slavery in the 19th century. Each of these movements tackled critical social issues, but only the Civil Rights Movement directly targeted racial segregation and aimed for integration and equality within American society.
