Which famous Supreme Court case is known for its significance in civil rights and was supported by the NAACP?

The case that is renowned for its significance in civil rights and received support from the NAACP is Brown v. Board of Education. Decided in 1954, this landmark Supreme Court ruling effectively declared that racial segregation in public schools was unconstitutional. The decision overturned the precedent set by Plessy v. Ferguson, which upheld the "separate but equal" doctrine.

The NAACP played a crucial role in the Brown case by providing legal support and representation, particularly through the efforts of Thurgood Marshall, who would later become the first African American Supreme Court Justice. The ruling was pivotal in the civil rights movement as it set a precedent for dismantling segregation and encouraged further legal challenges against discriminatory laws, marking a significant step towards equality and justice in the United States.

Other options, while also significant, pertain to different aspects of civil rights and liberties, but none resonate with the same foundational impact on public schooling and racial equality as Brown v. Board of Education.
