The Plessy v. Ferguson case involved Homer Plessy, a black man who was arrested for sitting in the whites-only car of a train in Louisiana in 1892. The case went to the Supreme Court to determine whether racial segregation of public facilities was constitutional. The Supreme Court ruled in a 7-1 decision that the doctrine of "separate but equal" was constitutional, allowing racial segregation if black and white facilities were equal. This decision had far-reaching negative impacts by legalizing racial segregation across many aspects of public life and encouraging the continuation of racism in America for decades.
