Step-by-step explanation:
Brown v. Board of Education (1954) overturned the doctrine of ‘separate but equal’ established by Plessy v. Ferguson (1896). The "Brown" case stated that segregation in American public schools was inherently unequal because educational facilities were separate but generally unequal due to disparities in funding and facilities. While it was initially ignored by many states, it was the beginning of the end of state-ordered segregation.
