What landmark case ruled segregation in public schools unconstitutional?

The landmark case that ruled segregation in public schools unconstitutional is Brown v. Board of Education. This 1954 Supreme Court decision essentially overturned the precedent set by Plessy v. Ferguson, which allowed for "separate but equal" facilities based on race. The Court in Brown v. Board of Education found that segregation in public schools violated the Equal Protection Clause of the Fourteenth Amendment, stating that separate educational facilities are inherently unequal. This ruling was pivotal in the Civil Rights Movement, as it set a legal precedent that challenged segregation and discrimination, leading to further efforts to dismantle institutional racism in various aspects of American life, particularly in education.
