The principle of separate but equal wasestablished by
(A) Brown v. Board of Education
(B) Wesbery v. Sanders
(C) Plessy v. Ferguson
(D) Regents of University of California v.
Bakke
(E) Heart of Atlanta Motel v. United States

Answers

The answer is C Plessy v. Ferguson. It is a landmark United States Supreme Court decision in the jurisprudence of the United State, upholding the constitutionally of state laws requiring racial segregation in public facilities under the doctrine of "separate but equal."

Final answer:

The principle of separate but equal was established by Plessy v. Ferguson, a U.S. Supreme Court decision of 1896. It advocated for separate facilities for white and non-white people, presuming that the facilities were equal, though this was not the case in practice. This principle was overruled by Brown v. Board of Education in 1954.

Explanation:

The principle of separate but equal was established by Plessy v. Ferguson, a landmark U.S. Supreme Court decision in 1896. This principle sanctioned the provision of separate public facilities for white and non-white people, on the condition that these facilities were presumed to be equal. However, in practice, these facilities were usually of inferior quality for non-white people, leading to inequality and injustice. The principle of separate but equal was overruled by Brown v. Board of Education in 1954, which declared that separate educational facilities were inherently unequal.
