Which landmark case desegregated public schools in the U.S.?

The landmark case that desegregated public schools in the U.S. is Brown v. Board of Education. Decided in 1954, this Supreme Court case challenged the legality of racial segregation in public schools. The Court ruled that "separate but equal" educational facilities for racial minorities and whites were inherently unequal, and thus unconstitutional under the Equal Protection Clause of the Fourteenth Amendment. This decision effectively overturned the precedent set by Plessy v. Ferguson, which had upheld segregation in public facilities, solidifying the legal foundation for desegregation across the nation. The ruling in Brown v. Board of Education was a significant catalyst for the civil rights movement, as it provided a legal framework for further challenges to discriminatory practices in various aspects of American life.
