Homer Plessy was arrested on June 7, 1892, for refusing to leave a whites-only railroad car in New Orleans, violating Louisiana’s Separate Car Act of 1890. The arrest was not a chance encounter. Plessy had agreed to break the law on purpose, working with a group of Black and Creole activists who wanted a test case that could challenge racial segregation in court. Everything about the day, from the ticket he bought to the detective who arrested him, was arranged in advance.
The Louisiana Law He Broke
The statute at the center of the arrest was Louisiana Act 111 of 1890, known as the Separate Car Act. It required every railroad carrying passengers within the state to provide “equal but separate accommodations for the white and colored races,” either through separate coaches or partitioned sections within a single car.1National Archives. Plessy v. Ferguson (1896) No passenger could sit in a coach assigned to the other race.
A passenger who insisted on sitting in the wrong section faced a $25 fine or up to 20 days in jail.1National Archives. Plessy v. Ferguson (1896) Conductors who failed to enforce the separation faced a fine of $25 to $50 per offense. Street railroads were exempt, but every intercity passenger train in Louisiana fell under the law.
Black residents of New Orleans had protested the bill in the state legislature in 1890. When the protests failed, opponents turned to the courts.
The Citizens’ Committee Behind the Arrest
The arrest was engineered by the Citizens’ Committee to Test the Constitutionality of the Separate Car Law, a group drawn largely from the Creole community of New Orleans. The committee raised roughly $3,000 to fund a lawsuit and hired Albion Tourgée, a white Northern attorney and civil rights advocate, as lead counsel. Louis A. Martinet, a Creole attorney and publisher of the New Orleans Daily Crusader, was among the driving forces behind the effort.
Their first attempt did not involve Plessy. In February 1892, a young man named Daniel Desdunes bought a first-class ticket on the Louisville & Nashville Railroad from New Orleans to Mobile, Alabama, and sat in the whites-only car. He was arrested as planned. But before trial, the Louisiana Supreme Court ruled in a separate case that the Separate Car Act could not apply to interstate passengers because interstate commerce was a federal matter. Since Desdunes had crossed state lines, Judge John Howard Ferguson dismissed the charges.
The committee needed a new passenger, one traveling entirely within Louisiana so the interstate commerce ruling would not apply. They also wanted someone whose racial identity would expose the strangeness of the law’s classification system. Plessy fit on both counts.
Why the Committee Chose Plessy
Plessy was seven-eighths European and one-eighth African by ancestry, with one Black great-grandparent. He could easily pass for white. Under Louisiana’s racial classification rules, though, that fraction of African ancestry was enough to categorize him as Black.1National Archives. Plessy v. Ferguson (1896)
The gap between how Plessy looked and how the law classified him was the point. If a man who appeared white could be arrested for sitting in the white car, what did racial separation actually mean? Conductors were expected to sort passengers by race on sight, yet Plessy’s appearance made that impossible without his own disclosure. The committee believed the contradiction would help show that the law was arbitrary and unconstitutional.
What Happened on June 7, 1892
The arrest itself was choreographed. The East Louisiana Railroad cooperated with the committee’s plan, likely because enforcing separate cars was expensive and operationally burdensome for the railroads themselves.1National Archives. Plessy v. Ferguson (1896) On June 7, 1892, Plessy purchased a first-class ticket on the East Louisiana Railroad line out of New Orleans and sat down in the whites-only coach.
When the conductor came through, Plessy identified himself as a person of color and refused to move to the car for Black passengers. A private detective named Chris Cain, hired by the committee for this exact moment, was already on the train. Cain arrested Plessy, who was removed from the train and booked for violating the Separate Car Act. The sequence unfolded exactly as designed.
What the Arrest Was Meant to Accomplish
The arrest was the door into a courtroom. Plessy was brought before Judge John Howard Ferguson in the Criminal District Court for the Parish of Orleans, the same judge who had dismissed the Desdunes case. Tourgée argued that the Separate Car Act violated both the Thirteenth Amendment, which abolished slavery, and the Fourteenth Amendment, which guaranteed equal protection under the law.2Justia U.S. Supreme Court Center. Plessy v. Ferguson, 163 U.S. 537 (1896)
Ferguson ruled against Plessy, holding that Louisiana had the authority to regulate railroads operating within its borders. Plessy was convicted and fined.2Justia U.S. Supreme Court Center. Plessy v. Ferguson, 163 U.S. 537 (1896) His lawyers appealed to the Louisiana Supreme Court, which upheld the conviction but granted a writ of error allowing the case to reach the U.S. Supreme Court. That had been the committee’s goal from the start.
What Came After
The Supreme Court heard the case in 1896 and ruled 7–1 against Plessy, with Justice John Marshall Harlan as the sole dissenter and Justice David Brewer not participating.3Legal Information Institute. Plessy v. Ferguson, 163 U.S. 537 The ruling established the “separate but equal” doctrine that gave constitutional cover to Jim Crow laws across the South for 58 years, until the Court’s 1954 decision in Brown v. Board of Education undid its legal logic in the context of public schools.
Plessy himself died in 1925, never having seen the legal system vindicate his challenge. In January 2022, Louisiana Governor John Bel Edwards granted him a full posthumous pardon, 130 years after his arrest, under a state law allowing pardons for people convicted of violating segregation statutes.
