@Paradise7D Plessy v Ferguson in 1896 the Court held that separate accommodations based on race was constitutional & did not violate the equal protection clause of the 14 Amendment (forbids the states from depriving any person of “life, liberty, or property, without due process of law” and from denying anyone equal protection under the law).
Later Brown vs Board of Edu of Topeka in 1954 ruled separate accommodations based on race were inherently unequal & unconstitutional (thus desegregation).
