The U.S. Supreme Court decision in Plessy v. Ferguson affirmed the state of Louisiana's constitutional right to offer "separate but equal" accommodations on railway lines within that state. The decision provided a legal basis for racial segregation in U.S. society, including segregation in education and other public services. The primary importance of the ruling was less to reinforce state's rights than to affirm the supposed legality of segregation. The decision produced increasingly significant consequences as U.S. society continued to segregate. Plessy v. Ferguson did not address poll taxes or the legality of railway strikes.
