Plessy v. Ferguson
Supreme Court case that upheld racial segregation under 'separate but equal.'
Plessy v. Ferguson was a landmark 1896 U.S. Supreme Court decision that upheld racial segregation laws, establishing the "separate but equal" doctrine. The case originated in Louisiana, which in 1890 passed the Separate Car Act requiring railroads to provide separate accommodations for white and black passengers. A New Orleans civil rights group, the Comité des Citoyens, organized a test case. They recruited Homer Plessy, a man of mixed-race ancestry who was classified as black under Louisiana law despite being fair-skinned. In 1892, Plessy bought a first-class ticket and boarded a whites-only train car in New Orleans. The railroad company, which opposed the law, had been informed of Plessy's racial background and the planned challenge. A private detective with arrest powers detained Plessy after he refused to move to the colored car. At trial, Judge John Howard Ferguson ruled that Louisiana could regulate railroads within its borders. The Louisiana Supreme Court upheld this ruling, citing precedents including an 1849 Massachusetts decision that segregated schools were constitutional. Plessy appealed to the U.S. Supreme Court. In a 7–1 decision, the Court ruled the Louisiana law did not violate the Fourteenth Amendment. It held that while the amendment established legal equality, it could not eliminate all distinctions based on color. The Court rejected arguments that segregation laws implied black inferiority and deferred to state legislatures' police powers. Justice John Marshall Harlan dissented, arguing the Constitution is color-blind and should not tolerate class distinctions. The decision legitimized Jim Crow laws across the American South. Plessy is considered one of the worst Supreme Court decisions, and though never explicitly overruled, it was effectively nullified beginning with the 1954 Brown v. Board of Education ruling.

Lore & Background
Plessy v. Ferguson arose from a carefully orchestrated challenge to Louisiana’s Separate Car Act of 1890, which mandated separate railway cars for white and Black passengers. The test case was organized by the Comité des Citoyens, a New Orleans civil rights group composed of Black, Creole of color, and white Creole residents. They selected Homer Plessy, a man of mixed-race ancestry—specifically an octoroon, meaning he was seven-eighths white and one-eighth Black—to participate. Though fair-skinned and born free, Plessy was classified as Black under Louisiana law and thus required to sit in the “colored” car. On June 7, 1892, he bought a first-class ticket and boarded a whites-only car of the East Louisiana Railroad in New Orleans. The railroad company, which opposed the law due to the expense of additional railcars, had been informed of Plessy’s racial background and the planned challenge. A private detective with arrest powers, also hired by the Comité, detained Plessy after he refused to leave the whites-only car, ensuring he would be charged under the Separate Car Act rather than for vagrancy. Plessy was taken off the train at Press and Royal streets and remanded for trial in Orleans Parish. At trial, Judge John Howard Ferguson ruled that Louisiana had the right to regulate railroads within its borders, denying Plessy’s motion to dismiss the charges. The Louisiana Supreme Court upheld this ruling, citing precedents including an 1849 Massachusetts decision that upheld segregated schools before the Fourteenth Amendment.
Reader's Guide
The Plessy decision provided the constitutional foundation for the Jim Crow system that re-segregated the American South after Reconstruction. By establishing the "separate but equal" doctrine, the ruling sanctioned a wide array of state laws mandating racial separation in public facilities, transportation, and accommodations. The case originated from a deliberate test orchestrated by the Comité des Citoyens, a New Orleans civil rights group composed of black, Creole of color, and white Creole residents. They selected Homer Plessy, a fair-skinned octoroon who was legally classified as black under Louisiana law, to challenge the Separate Car Act. The railroad company, which opposed the law due to the expense of additional railcars, cooperated with the plan. A private detective with arrest powers detained Plessy after he refused to leave a whites-only car, ensuring he would be charged under the Act rather than for vagrancy. The Supreme Court’s majority deferred to state legislatures’ police power to regulate health, safety, and morals, rejecting arguments that segregation implied black inferiority. Justice Harlan’s lone dissent argued the Constitution is color-blind and cannot tolerate class distinctions. Though never explicitly overruled, the decision was effectively nullified starting with *Brown v. Board of Education*, which found segregated schools inherently unequal.
