Convict leasing was a system, used mainly across the American South from the late 1860s until 1928, in which state governments rented imprisoned people to private companies for a per-capita fee. The companies put those workers into coal mines, turpentine forests, railroad grades, and cotton fields, covered the costs of housing and guarding them, and kept whatever profit the labor produced. The practice drew its legal authority from a single clause of the Thirteenth Amendment, and at its height it supplied the majority of some Southern states’ operating revenue while killing prisoners at rates many times those of ordinary penitentiaries.
The Constitutional Hook
The Thirteenth Amendment abolished slavery and involuntary servitude, with one exception written into the text: “except as a punishment for crime whereof the party shall have been duly convicted.”1Constitution Annotated. U.S. Constitution – Thirteenth Amendment That carve-out is what made leasing legally possible. A conviction, in the courts’ reading, stripped a person of the rights that would otherwise have blocked the state from compelling labor or transferring control of a body to a third party.
A Virginia court made that reading explicit in 1871. In Ruffin v. Commonwealth, the judges wrote that a convicted person “has, as a consequence of his crime, not only forfeited his liberty, but all his personal rights except those which the law in its humanity accords to him. He is for the time being the slave of the state.” Once a prisoner was treated as state property, leasing that property to a railroad or mining company raised no greater legal question than leasing out any other asset. Challenges based on individual rights ran into the same wall: conviction had already removed those rights.
How People Ended Up Leased
The constitutional clause supplied the mechanism. The supply of workers came from state criminal codes written specifically to produce convictions among newly freed Black people. Southern legislatures passed Black Codes immediately after the Civil War that defined ordinary conduct as a crime when a freedman did it. Mississippi’s 1865 vagrancy statute treated any freedman over eighteen as a vagrant if he was found “with no lawful employment or business” or “unlawfully assembling” at any hour, and nonpayment of a tax counted as automatic evidence of vagrancy.2National Constitution Center. Black Codes (1865)
From conviction, the path into leased labor was short. A person who could not pay a fine had their labor sold to anyone willing to cover it. Mississippi’s penal code directed that any freedman who failed to pay a fine within five days “shall be hired out by the sheriff or other officer, at public outcry, to any white person who will pay said fine and all costs.”2National Constitution Center. Black Codes (1865) County-level systems fed on convictions for using profanity, gambling, petty theft of items worth only a few dollars, or selling whiskey, and many of those leased at the county level were handed over with no record kept of their offenses or sentences.3NYU Law Review.

The racial pattern was not incidental. By the 1870s, roughly 95 percent of people in criminal custody across Southern states were Black. An investigation of Georgia’s system in 1908 found that 90 percent of state prisoners were Black. The pipeline was engineered to produce that result.
The Contracts and the Money
States formalized leasing through contracts signed at the governor’s office or by the legislature. These agreements set the number of workers transferred and the length of service, which could run a decade or longer. In 1876, Georgia’s legislature authorized leasing all state prisoners to one or more companies for a minimum of twenty years. Alabama’s legislature approved a plan in 1883 to lease the majority of its prisoners to a handful of mining firms.4Alabama Department of Archives and History. Convict Department Records
Companies paid a monthly fee for each prisoner. Rates varied by state, industry, and era. Florida leased prisoners to an intermediary turpentine association for roughly $280 per person per year, and the association subleased them to individual camp operators for around $400 per head. The revenue mattered enormously to state budgets. By 1898, convict leasing accounted for nearly 73 percent of Alabama’s total state revenue, which made the government financially dependent on the practice continuing.
What made the arrangement especially cheap for states and especially dangerous for prisoners was how the contracts allocated risk. The private lessee took on the costs of feeding, clothing, housing, and guarding the people assigned to them.5Library of Congress. Pratt Coal and Coke Company, Pratt Mines, Convict Yards In exchange, the state removed itself from operating expenses while collecting revenue. One recurring clause in Alabama’s contracts released the lessee from all liability for “escapes, sicknesses, loss of prisoner, fire or any other casualty whatsoever.”6National Center for Biotechnology Information. Dark Heritage in the New South: Remembering Convict Leasing in Southern Middle Tennessee through Community Archaeology A dead prisoner cost the company nothing. A saying circulated among lessees: “One dies, get another.”
Inspectors existed on paper. They had no enforcement power, and the same officials who oversaw camp conditions collected the lease payments. Any improvement in conditions was a cost the lessee would resist and the state had no reason to impose.
Life in the Camps
Workers lived in stockades or camps built close to the labor site. The Pratt Mines complex in Alabama included frame buildings for a prison structure, a kitchen, a dining commissary, and a bathhouse, which was relatively developed for the system.5Library of Congress. Pratt Coal and Coke Company, Pratt Mines, Convict Yards Many camps, especially in remote turpentine country, were rough board shanties or canvas tents with no weather protection, little sanitation, and severe overcrowding.
The workday ran long regardless of industry. Prisoners at Pratt worked ten-hour shifts underground and had daily production quotas to meet.5Library of Congress. Pratt Coal and Coke Company, Pratt Mines, Convict Yards In turpentine camps, labor began at sunrise and ran past dark, with workers wading through swamps to collect pine resin in tattered clothing and no shoes. Missing a quota meant a whipping. At Tennessee’s Lone Rock Stockade, guards used a two-and-a-half-pound leather strap made of two layers of sole leather riveted to a wooden handle. Prisoners were stripped, laid on a plank, and beaten with anywhere from five to fifty lashes.6National Center for Biotechnology Information. Dark Heritage in the New South: Remembering Convict Leasing in Southern Middle Tennessee through Community Archaeology Beyond the beatings, prisoners went without adequate blankets, socks, or food, and were allowed to bathe only once a week.
Mortality tracked the conditions. At the Pratt Mines, the death rate hit 18 percent in 1881. A physician assigned to the site brought it down to two percent by 1884 through better sanitation, food, and shorter hours, which showed that the lethal baseline reflected choices rather than necessity.5Library of Congress. Pratt Coal and Coke Company, Pratt Mines, Convict Yards At the Lone Rock Stockade, annual mortality held at just under ten percent for the duration of its operation, driven by tuberculosis, typhoid, diarrhea, and mine accidents from inadequately supported ceilings.6National Center for Biotechnology Information.

Industries and Companies
Coal and iron mining absorbed the largest share of leased labor. Underground extraction was dangerous and physically brutal, and free miners could strike or walk off the job. Convict workers could do neither. In Alabama, three companies dominated after the 1883 leasing plan: Pratt Coal and Iron Company, Tennessee Coal, Iron and Railroad Company (TCI), and Sloss Iron and Steel Company.4Alabama Department of Archives and History. Convict Department Records By 1906, Pratt Mines alone held 906 state convicts.5Library of Congress. Pratt Coal and Coke Company, Pratt Mines, Convict Yards TCI had begun leasing 300 convicts from Tennessee as early as 1871 for its Tracy City and Battle Creek mines, eventually running stockades that fluctuated between 350 and more than 500 workers at a time.6National Center for Biotechnology Information. Dark Heritage in the New South: Remembering Convict Leasing in Southern Middle Tennessee through Community Archaeology
Mining disasters hit this population hardest. An explosion at Alabama’s Banner Mine in April 1911 killed 128 men, almost all Black state prisoners. By 1900, Black workers made up 65 percent of Alabama’s coal mining labor force and 90 percent of convicts at the Pratt Mines.5Library of Congress. Pratt Coal and Coke Company, Pratt Mines, Convict Yards
Turpentine and timber operations formed the other major sector. Workers were stationed deep in pine forests, scraping hardened resin from tree trunks and hauling sap through swamps. The isolation of these camps shielded the worst conditions from any outside look. Railroad construction and large-scale agriculture used convict crews too. Private operation of a state facility predated the formal state leasing systems: as early as 1846, a private businessman leased Alabama’s Wetumpka State Penitentiary for six years and ran it for profit.4Alabama Department of Archives and History. Convict Department Records
How It Ended
Convict leasing wound down state by state over roughly two decades, pushed by public outrage, organized labor opposition, and federal legislation. TCI stopped using convict labor in its Alabama mines in 1914, but other mining companies in the same district continued until 1928.5Library of Congress. Pratt Coal and Coke Company, Pratt Mines, Convict Yards Alabama was the last state to formally abolish the practice, ending it in 1928.4Alabama Department of Archives and History. Convict Department Records
Federal law chipped away at the economics. The Hawes-Cooper Act of 1929 stripped prisoner-made goods of their interstate commerce protections, so that once those products reached a destination state they became subject to that state’s rules on sale and distribution.7GovInfo. Federal Register, Volume 64, Issue 66 The Ashurst-Sumners Act of 1935 made knowingly transporting prisoner-made goods in interstate commerce a federal crime. In 1941, the federal government issued Circular 3591, which formally prohibited the leasing of convict labor. The timing coincided with the United States entering World War II and official concern that the system’s brutality would feed enemy propaganda.
What the Punishment Clause Left Behind
Convict leasing as a practice is gone, but the Thirteenth Amendment’s punishment clause is still in the Constitution, and the principle that a conviction can be the basis for compelled labor has not been overturned. What replaced leasing was state-run prison industry and, starting in 1979, the Prison Industry Enhancement Certification Program, which allows certified state and local programs to sell prisoner-made goods in interstate commerce under rules requiring prevailing wages and realistic work environments.8Bureau of Justice Assistance. Prison Industry Enhancement Certification Program Overview Outside that certified program, prison labor pay rates still range from nothing to a few dollars per hour, with most well under two dollars, and several states assign work without any pay.
In 2022, voters in Alabama, Oregon, Tennessee, and Vermont approved state constitutional amendments prohibiting slavery and involuntary servitude as punishment for crime. Louisiana attempted a similar measure the same year but withdrew it over ambiguous wording. None of those changes touch the federal Constitution, where the punishment clause remains intact.
