What movement aimed to end racial discrimination?

The civil rights movement is specifically known for its focus on ending racial discrimination and securing equal rights for all individuals, particularly African Americans, who faced systemic injustices and segregation in various aspects of life. This movement gained momentum during the 1950s and 1960s, led by influential figures such as Martin Luther King Jr., Rosa Parks, and Malcolm X, among others. It sought to dismantle discriminatory laws and practices through various means, including peaceful protests, legal challenges, and grassroots organizing.

The labor movement, while significant in advocating for workers' rights and better conditions, does not primarily target racial discrimination. Similarly, the women's suffrage movement focused on granting women the right to vote rather than addressing racial issues specifically. The environmental movement, on the other hand, is concerned with environmental conservation and sustainability, rather than civil rights. Thus, the civil rights movement stands out as the correct answer due to its direct aim of combating racial discrimination and promoting equality.
