Landmark Case of Separate but Equal

The Fourteenth Amendment to the United States Constitution is a pivotal piece of legislation that addresses citizenship rights and equal protection under the law. In what landmark case did the Supreme Court rule that a state law requiring separate but equal public facilities for racial minorities and whites was constitutional, thus establishing the doctrine of 'separate but equal'?

This case set a precedent that would later be challenged in various civil rights movements and was ultimately undermined by later decisions advocating for racial equality.
