Reader's Guide
Plessy v. Ferguson is significant for establishing the 'separate but equal' doctrine, which allowed states to mandate racial segregation as long as facilities for each race were nominally equal. The Supreme Court's 7–1 decision held that the Louisiana law did not violate the Fourteenth Amendment, reasoning that the amendment guaranteed legal equality but could not eliminate all distinctions based on color. Justice John Marshall Harlan's lone dissent argued that the Constitution is 'color-blind' and that such laws should be unconstitutional. The decision legitimized Jim Crow laws across the American South for decades. Although never explicitly overruled, Plessy was severely weakened by a series of later Court decisions, starting with Brown v.
