Final answer:
The Supreme Court's Brown v. Board of Education decision overturned Plessy v. Ferguson and ruled that segregated education was unconstitutional.
Step-by-step explanation:
The Supreme Court did not try to overrule Plessy v. Ferguson, but rather took action to reverse the damage caused by that decision. The landmark case of Brown v. Board of Education in 1954 overturned Plessy v. Ferguson as it pertained to public education. The Supreme Court ruled that a separate but equal education was not possible, as segregated schools could not provide the same teachers or environment as integrated schools. This decision laid the groundwork for future legal decisions that made segregation unconstitutional in various institutions.
