Which event marked the end of "separate but equal" education in the U.S.?

The end of the "separate but equal" doctrine in education is marked by the landmark Supreme Court case Brown v. Board of Education. This 1954 decision declared that racial segregation in public schools was unconstitutional, effectively overturning the precedent established by Plessy v. Ferguson in 1896, which upheld the legality of racial segregation under the "separate but equal" doctrine. The Brown case brought to light the inherent inequalities in segregated schools and recognized that separate educational facilities are inherently unequal, thus violating the Equal Protection Clause of the Fourteenth Amendment. This ruling paved the way for desegregation across the United States and significantly advanced the civil rights movement. The other cases mentioned do not specifically relate to the issue of educational segregation; rather, they focus on different legal principles and rights.
