What movement tried to end racial discrimination?

The Civil Rights Movement is the correct choice because it specifically aimed to eliminate racial discrimination and ensure equal rights for all individuals, particularly focusing on African Americans in the United States during the 1950s and 1960s. This movement sought to address systemic injustices and segregation that were prevalent in society, advocating for civil rights through peaceful protests, legal challenges, and grassroots organizing. Key figures such as Martin Luther King Jr., Rosa Parks, and Malcolm X emerged from this movement, which led to significant legislative changes, including the Civil Rights Act of 1964 and the Voting Rights Act of 1965.

In contrast, the Women's Suffrage Movement focused on securing voting rights for women, the Labor Movement aimed at improving working conditions and wages for laborers, and the Environmental Movement seeks to protect the planet's natural resources and promote sustainability. Each of these movements addresses important issues, but none specifically targeted racial discrimination to the extent that the Civil Rights Movement did.
