Which movement aimed to end racial discrimination in the United States?

The Civil Rights Movement is the movement specifically aimed at ending racial discrimination in the United States. It emerged prominently in the 1950s and 1960s, focusing on the legal and social challenges faced by African Americans due to systemic racism. Key goals included desegregation, voting rights, and equal treatment under the law, which were pursued through various means, including protests, legal challenges, and advocacy by influential leaders like Martin Luther King Jr. and Malcolm X.

This movement was characterized by landmark events such as the March on Washington, where King delivered his famous "I Have a Dream" speech, and the Civil Rights Act of 1964 and Voting Rights Act of 1965, which significantly advanced the rights of minority populations.

In contrast, the other movements mentioned focused on different social issues: the Progressive Movement primarily addressed social and political reform, the Labor Movement centered on worker's rights and labor conditions, and the Suffrage Movement fought for women's right to vote. While all these movements contributed to advancing social justice in the U.S., the Civil Rights Movement specifically targeted the issue of racial inequality, making it the correct answer to the question.
