What group challenged a racial discrimination in the courts?

The NAACP (National Association for the Advancement of Colored People) played a pivotal role in challenging racial discrimination in the courts. Through strategic legal battles, including landmark cases like Brown v. Board of Education in 1954, the NAACP sought to dismantle segregation and uphold civil rights for African Americans. Their efforts laid the groundwork for the Civil Rights Movement and significantly influenced U.S. law regarding racial equality.
