What landmark Supreme Court case overturned the "separate but equal" doctrine established in Plessy vs. Ferguson?

The case that overturned the "separate but equal" doctrine established in Plessy v. Ferguson is Brown v. Board of Education. This landmark 1954 Supreme Court ruling declared that racial segregation in public schools was unconstitutional, fundamentally challenging the legality of segregated education based on the premise that separate facilities are inherently unequal. The decision was pivotal in the civil rights movement, as it provided a legal foundation for challenging segregation and discrimination across various aspects of society.

In contrast, the other cases mentioned do not pertain to this issue. Roe v. Wade addresses women's rights regarding reproductive choices, focusing on abortion. Mapp v. Ohio deals with the exclusionary rule and the Fourth Amendment relating to illegal searches and seizures. Korematsu v. United States addresses the internment of Japanese Americans during World War II, which is unrelated to the education and segregation laws reversed by Brown v. Board of Education.
