One of the most significant court cases that was used to justify Jim Crow laws was Plessy v. Ferguson. The case began when black Americans challenged the new enforced law in Louisiana requiring railroad passengers to ride in segregated cars. The case originated in New Orleans when Homer Plessy, who was one-eighth black, refused to leave a whites-only railroad car and was convicted of violating the law. The Supreme Court ruled 7 to 1 that separating the races did not mean that one race was being treated unequally. As long as segregated facilities were “separate but equal,” they were acceptable as a matter of social policy. Soon after the court’s ruling, the widespread practice of “separate but equal” facilities became apart of virtually every area of southern life.
