The 13th Amendment quote reads in full: “Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction. Congress shall have power to enforce this article by appropriate legislation.”1Congress.gov. U.S. Constitution – Thirteenth Amendment Ratified on December 6, 1865, it abolished slavery throughout the country and gave Congress the authority to back that ban up with legislation.2National Archives. 13th Amendment to the U.S. Constitution – Abolition of Slavery
The Two Sections, Line by Line
Section 1. “Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction.”
Section 2. “Congress shall have power to enforce this article by appropriate legislation.”
Section 1 does two separate things. It bans slavery outright, and it also bans “involuntary servitude,” a broader category that reaches forced-labor arrangements that don’t fit the historical picture of chattel slavery but function the same way. The single carve-out is for people serving a criminal sentence. Section 2 hands Congress the authority to write laws that give the prohibition real force.1Congress.gov. U.S. Constitution – Thirteenth Amendment
What “Involuntary Servitude” Means
The phrase is doing heavy work in the amendment. Under federal law, involuntary servitude covers any situation where a person is forced to work through a scheme designed to make them believe they or someone else will face serious harm or physical restraint if they stop, or through abuse of the legal system.3Office of the Law Revision Counsel. 22 USC 7102 – Definitions
That reaches modern forms of coercion. An employer who threatens to call immigration authorities unless a worker keeps laboring is engaging in exactly the legal-process abuse the statute targets.4U.S. Department of Justice. Involuntary Servitude, Forced Labor, and Sex Trafficking Statutes Enforced5Office of the Law Revision Counsel. 18 USC 1589 – Forced Labor6Office of the Law Revision Counsel. 18 U.S. Code 1584 – Sale Into Involuntary Servitude7Office of the Law Revision Counsel. 18 USC 1581 – Peonage, Obstructing Enforcement
The “Except as a Punishment for Crime” Clause
The most-discussed words in the amendment carve out a deliberate exception: forced labor is permitted as punishment for someone “duly convicted” of a crime. That phrase does real work. A person must go through a formal legal proceeding and receive a conviction before any compelled labor is lawful. People awaiting trial, immigration detainees, and anyone not yet convicted fall outside the exception.
Prison labor programs operate under this clause. Incarcerated workers perform manufacturing, facility maintenance, agricultural work, and in some states wildfire suppression. Because courts have generally held that incarcerated workers are not “employees” under the Fair Labor Standards Act, prisons are not required to pay the federal minimum wage.8U.S. Government Accountability Office. Prisoner Labor – Perspectives on Paying the Federal Minimum Wage
Since 2018, voters in at least seven states — Colorado, Nebraska, Utah, Alabama, Oregon, Tennessee, and Vermont — have approved state constitutional amendments removing similar punishment-for-crime language from their own charters. Those changes do not override the federal Constitution’s exception, but they give incarcerated people in those states grounds to challenge exploitative labor practices under state law.
What the Amendment Does Not Reach
Not every form of compelled service counts as involuntary servitude. The Supreme Court ruled in 1916 that the amendment targets forms of compulsory labor resembling slavery and was never intended to block ordinary civic obligations like jury duty, militia service, or required work on public roads.9Library of Congress. Butler v. Perry, 240 U.S. 328 The military draft sits in the same category. When the Selective Service Act was challenged during World War I, the Court held that compulsory military service is part of the basic duty citizens owe a just government and does not conflict with the 13th Amendment.10Justia U.S. Supreme Court Center. Selective Draft Law Cases, 245 U.S. 366
Why Section 2 Matters
The second sentence — Congress’s enforcement power — has done more work than its brevity suggests. In 1968, the Supreme Court ruled that Congress can identify and legislate against the “badges and incidents” of slavery, meaning the lingering practices and restrictions that replicate the conditions of bondage rather than just the literal ownership of people.11Justia U.S. Supreme Court Center. Jones v. Alfred H. Mayer Co., 392 U.S. 409 The Court held those badges and incidents include interference with fundamental rights like the ability to buy, sell, lease, and inherit property on equal terms.
Federal trafficking statutes, anti-peonage laws, and civil rights protections against racially motivated interference with economic freedoms all trace their constitutional foundation to that short second section. And unlike the 14th Amendment, which only restricts government action, the 13th Amendment’s enforcement power allows Congress to regulate private conduct, so individuals and businesses can be held accountable for practices that echo slavery’s conditions.1Congress.gov.
