What movement tried to end racial discrimination?

The Civil Rights Movement aimed specifically to end racial discrimination and achieve equality for African Americans in the United States. This movement emerged prominently in the mid-20th century and was characterized by a series of protests, legal challenges, and public campaigns designed to eliminate segregation and ensure voting rights, desegregation of public places, and other fundamental civil liberties. Key figures such as Martin Luther King Jr., Rosa Parks, and Malcolm X played significant roles in advocating for change and mobilizing support across the nation.

While the other movements listed—Women's Suffrage, Labor, and Environmental—focused on very important issues, they were not primarily concerned with racial discrimination. The Women's Suffrage Movement concentrated on securing the right to vote for women. The Labor Movement sought to improve working conditions and labor rights, and the Environmental Movement focuses on issues related to nature and conservation. Each of these movements has its own unique goals and historical context, but the Civil Rights Movement distinctly targeted racial inequality, making it the correct answer for the question about efforts to end racial discrimination.
