Answer 2

The Supreme Court decision that found separate but equal schools to be unconstitutional and fundamentally unequal was Brown v. Board of Education (1954). This landmark ruling declared that racial segregation in public schools violated the Equal Protection Clause of the Fourteenth Amendment. It overturned the "separate but equal" doctrine established in Plessy v. Ferguson (1896).
