What movement tried to end racial discrimination?

The Civil Rights Movement is the correct answer because it was specifically focused on achieving equal rights and ending racial discrimination, particularly against African Americans in the United States. This movement gained momentum during the 1950s and 1960s and aimed to dismantle institutionalized racial segregation and discrimination through various forms of activism, including peaceful protests, legal challenges, and legislative advocacy. Key events, such as the March on Washington and the Montgomery Bus Boycott, along with landmark legislation like the Civil Rights Act of 1964 and the Voting Rights Act of 1965, were significant outcomes of this movement.

In contrast, the Labor Movement primarily seeks to improve labor conditions, wages, and workers' rights rather than focusing exclusively on racial issues. The Women's Suffrage Movement aimed at securing voting rights for women, which, while significant for gender equality, does not directly address racial discrimination. The Environmental Movement focuses on ecological issues and the protection of the environment rather than social justice and equality. Thus, the Civil Rights Movement stands out as the movement dedicated to combating racial discrimination.
