The Louisiana Separate Car Act, passed as Act 111 of 1890, required every railroad operating passenger service in the state to segregate white and Black riders into separate coaches or partitioned compartments. It made the seating assignment a conductor’s job, backed it with fines and jail time for passengers and employees alike, and six years later produced Plessy v. Ferguson, the Supreme Court decision that gave “separate but equal” its constitutional footing until 1954.
What the Law Required
Act 111 gave railroads two ways to comply. A company could run separate coaches for white and Black passengers, or it could install a partition inside a single coach to create two distinct compartments.1Bill of Rights Institute. Louisiana Separate Car Act, 1890 Either way, the statute required the accommodations to be “equal but separate.” No passenger could sit in a coach or compartment other than the one designated for their race.
Every railroad carrying passengers in Louisiana had to comply. The law left no room for a company to decide segregation was unnecessary on a particular route, so a short rural line faced the same obligation as a major urban carrier.
How Conductors Enforced It
Enforcement fell on train officers, primarily conductors. They had both the authority and the legal duty to assign every passenger to the correct coach or compartment based on race.1Bill of Rights Institute. Louisiana Separate Car Act, 1890 If a passenger refused the assignment, the conductor could put the person off the train.
The statute also protected the people doing the enforcing. Neither the conductor nor the railroad company could be sued for damages arising from a refusal to carry a noncompliant passenger.1Bill of Rights Institute. Louisiana Separate Car Act, 1890 That turned private employees into state-backed agents of segregation with legal cover for their decisions.
Fines and Jail Time
Penalties ran in both directions. A passenger who insisted on sitting in a coach designated for the other race faced a fine of twenty-five dollars or, if unable to pay, up to twenty days in the parish jail.1Bill of Rights Institute. Louisiana Separate Car Act, 1890 Railroad employees who refused to enforce the seating rules faced the same twenty-five-dollar fine or twenty days in jail. The companies themselves could be fined for failing to provide the required separate or partitioned coaches.
Twenty-five dollars was not a trivial sum in 1890. For a working-class passenger or a modestly paid conductor, the fine alone was enough to produce compliance.
The Nursing Exception
The act carved out one exception to its racial boundaries: nurses attending children of the other race could remain in the child’s designated compartment.1Bill of Rights Institute. Louisiana Separate Car Act, 1890 In practice, that allowed Black domestic workers caring for white children to sit in the white car without criminal exposure. The line bent exactly where it served the convenience of white families, and nowhere else.
A Deliberate Test Case
The constitutional challenge to the act was planned. In 1891, a New Orleans civil rights organization called the Comité des Citoyens (Citizens’ Committee) formed specifically to attack the law. Its eighteen members were mostly Afro-Creole professionals: educators, lawyers, business owners, and former Union soldiers. The group pooled resources and hired Albion Tourgée, a prominent civil rights attorney from New York, to lead the case.
The committee chose Homer Plessy as the test plaintiff. Plessy was one-eighth Black and seven-eighths white, and his appearance was central to the strategy: if a man who looked nearly white could be arrested simply for sitting in the wrong car, the law’s racial classifications would look arbitrary. On June 7, 1892, Plessy boarded a whites-only car at Press and Royal Streets in New Orleans with the cooperation of the East Louisiana Railroad.2National Archives. Plessy v. Ferguson The conductor asked whether he was a “colored man,” Plessy confirmed he was, and when he refused to move, the train was stopped and he was arrested.
The railroad’s role mattered. Running separate coaches was expensive and operationally burdensome, and the East Louisiana Railroad was a willing participant in a case designed to strike the law down. Even the private detective who made the arrest had been arranged in advance by the committee.
The Supreme Court’s Ruling in Plessy v. Ferguson
The case reached the U.S. Supreme Court, which decided it in 1896. By a 7-1 vote, the Court upheld the Separate Car Act.3Justia U.S. Supreme Court Center. Plessy v. Ferguson Justice David Brewer did not participate.
Plessy’s attorneys argued the law violated two constitutional amendments. The Thirteenth Amendment, they said, barred not only literal slavery but laws imposing a “badge of servitude” on Black citizens. The Fourteenth Amendment, they argued, guaranteed equal protection and could not permit state-mandated racial separation.4Oyez. Plessy v. Ferguson
Justice Henry Billings Brown, writing for the majority, rejected both arguments. On the Thirteenth Amendment, he wrote that a legal distinction between the races had “no tendency to destroy the legal equality of the two races, or re-establish a state of involuntary servitude.”2National Archives. Plessy v. Ferguson On the Fourteenth, Brown acknowledged the amendment was meant to enforce “absolute equality of the two races before the law” but concluded it was never intended to abolish distinctions based on color or force social mixing. So long as separate facilities were equal, the arrangement fell within the state’s police power.
Brown dismissed the idea that separation stamped Black citizens with a badge of inferiority. If Black people felt that way, he wrote, “it is not by reason of anything found in the act, but solely because the colored race chooses to put that construction upon it.”2National Archives. Plessy v. Ferguson
Justice Harlan’s Dissent
Justice John Marshall Harlan dissented alone. He wrote that “the arbitrary separation of citizens on the basis of race, while they are on a public highway, is a badge of servitude wholly inconsistent with the civil freedom and the equality before the law established by the Constitution.”
Where the majority held that segregation did not imply inferiority, Harlan asked: “What can more certainly arouse race hate, what more certainly create and perpetuate a feeling of distrust between these races, than state enactments, which, in fact, proceed on the ground that colored citizens are so inferior and degraded that they cannot be allowed to sit in public coaches occupied by white citizens?”
His most quoted line became a touchstone for the civil rights movement: “Our constitution is colorblind, and neither knows nor tolerates classes among citizens.” Harlan warned that Plessy would prove as damaging as Dred Scott v. Sandford.
How the Law Was Finally Undone
The dismantling came in stages. In 1954, the Supreme Court unanimously overturned “separate but equal” in Brown v. Board of Education, ruling that racially segregated public schools were “inherently unequal” and violated the Fourteenth Amendment’s Equal Protection Clause.5Oyez. Brown v. Board of Education of Topeka The Court reasoned that segregation instilled a sense of inferiority in Black children that undermined their education. Brown directly repudiated the core holding of Plessy.
Transit segregation took a further blow in 1960, when the Court ruled in Boynton v. Virginia that a bus terminal restaurant serving interstate passengers could not enforce racial separation. The Interstate Commerce Act’s prohibition on unjust discrimination, the Court held, extended to terminal facilities that carriers made available as a regular part of travel.6Justia U.S. Supreme Court Center. Boynton v. Virginia
The final blow came through legislation. Title II of the Civil Rights Act of 1964 guaranteed all people the “full and equal enjoyment” of public accommodations without discrimination based on race, color, religion, or national origin.7Department of Justice. Title II of the Civil Rights Act – Public Accommodations That law made any remnant of the Separate Car Act unenforceable as a matter of federal supremacy.
In January 2022, more than a century after his arrest, Louisiana’s governor posthumously pardoned Homer Plessy.8Library of Congress. The Posthumous Pardon of Homer Plessy
