Which case overturned the "separate but equal" doctrine?

The case that overturned the "separate but equal" doctrine is Brown v. Board of Education. This landmark Supreme Court decision, rendered in 1954, held that racial segregation in public schools violated the Equal Protection Clause of the Fourteenth Amendment. The Court found that separate educational facilities are inherently unequal, thereby rejecting the longstanding precedent established by Plessy v. Ferguson in 1896, which upheld segregation so long as the separate facilities were deemed equal.

The significance of Brown v. Board of Education extends beyond education; it laid the groundwork for the civil rights movement by affirming that segregation based on race is unconstitutional. It recognized the detrimental effects of segregation on African American children and emphasized the importance of integration in fostering equality and opportunity.

Other cases listed do not relate to the doctrine of "separate but equal." Roe v. Wade addresses the issue of abortion rights; Obergefell v. Hodges concerns same-sex marriage; and Miranda v. Arizona deals with the rights of the accused in criminal proceedings. Each of these cases has its own significant impact on constitutional law, but none address racial segregation in the same way that Brown v. Board of Education does.
