The primary sources for the 13th Amendment are the enrolled joint resolution passed by the 38th Congress and signed on February 1, 1865, the Congressional Globe debates covering its introduction and passage, the individual state ratification certificates transmitted to Washington, and Secretary of State William Seward’s Proclamation of Adoption issued December 18, 1865. These documents survive in federal collections at the National Archives, the Library of Congress, and Congress.gov, and together they form the complete legal record of how slavery and involuntary servitude were abolished by constitutional amendment.
The Core Documents at a Glance
Six categories of primary source do the real work for anyone researching the amendment:
- The constitutional text itself, as reproduced from the enrolled original.
- The enrolled joint resolution held in Record Group 11 at the National Archives.
- A separate ceremonial copy signed by members of Congress and by Lincoln, held at the Library of Congress.
- The Congressional Globe volumes covering the 38th Congress (1863–1865).
- State ratification certificates from the 27 states that approved the amendment by December 6, 1865.
- Seward’s Proclamation of Adoption, held within Department of State records.
The Emancipation Proclamation is often filed alongside these materials, but it is a different kind of document with different legal force, and it is treated separately below.
The Constitutional Text
Section 1 of the amendment reads: “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.” The drafters included “involuntary servitude” alongside “slavery” so the amendment would reach forced labor arrangements that did not technically qualify as chattel slavery. The exception for criminal punishment has permitted prison labor systems and continues to generate legal and political debate.
Section 2 reads: “Congress shall have power to enforce this article by appropriate legislation.” That enforcement clause gave Congress authority to pass statutes backing up the ban rather than leaving enforcement to the courts alone. It is the constitutional foundation Congress used within a year to pass the Civil Rights Act of 1866, and it remains the basis for modern federal anti-trafficking law.
The authoritative text appears on the Constitution Annotated site maintained by Congress at constitution.congress.gov and on the Legal Information Institute at Cornell Law. Both reproduce the language from the enrolled original.
The Enrolled Joint Resolution
The physical enrolled joint resolution is held at the National Archives in Record Group 11, the General Records of the United States Government, alongside the Bill of Rights and other constitutional amendments. It is the perfected version of the bill as passed by both chambers, bearing the signatures of the Speaker of the House and the Vice President acting as President of the Senate. For any question about the exact language sent to the states, this is the definitive source.
Lincoln signed the resolution on February 1, 1865. A presidential signature on a constitutional amendment carries no legal weight; the Supreme Court settled that in Hollingsworth v. Virginia (1798), where Justice Chase wrote that the president “has nothing to do with the proposition, or adoption, of amendments to the Constitution.” Lincoln’s signature was a political statement, and the Senate later passed a separate resolution affirming the point. The document remains under environmental controls at the Archives designed to protect ink and parchment.
The Ceremonial Copy Is a Separate Document
A distinct ceremonial copy of the amendment survives, signed by members of Congress after passage in their respective chambers, with Lincoln’s signature added as well. The U.S. Capitol Visitor Center describes it as “a measure of the importance placed on the passage of the Thirteenth Amendment.” This copy is held in the Manuscript Division of the Library of Congress, not at the National Archives. Researchers sometimes conflate the two; the enrolled resolution is the legally operative document, and the ceremonial copy is a historical artifact of the political moment.
Congressional Globe Debates and Votes
The legislative history lives in the Congressional Globe, the predecessor to today’s Congressional Record. The Globe captured daily floor debates, motions, and roll-call votes for Congress from 1833 through 1873. For the 38th Congress, its volumes document every stage of the amendment’s passage, from the introduction of Senate Joint Resolution 16 by Senator John Henderson through the final votes. The scanned original pages, in the newspaper-style layout used at the time, are browsable through Congress.gov.
The Senate approved the resolution on April 8, 1864, by a vote of 38 to 6. The House initially failed to reach the required two-thirds supermajority. After intense lobbying following Lincoln’s reelection, the House passed the measure on January 31, 1865, by a vote of 119 to 56. Every motion and proposed modification during the committee stages appears in these multi-volume sets, along with the position of each representative and the names of those absent or abstaining from the final roll call.
The floor transcripts show arguments about the legal necessity of embedding abolition in the Constitution rather than relying on executive authority. Border-state lawmakers raised pointed concerns about the status of enslaved people in jurisdictions the Emancipation Proclamation had not touched. Courts have relied on these debates when interpreting the amendment’s scope, and they are the standard resource when a researcher needs legislative intent.
State Ratification Certificates and Seward’s Proclamation
Each state legislature that ratified generated its own primary record: a formal certificate of ratification bearing the official seal and signatures of the governor or legislative leaders. These certificates were transmitted to the Secretary of State in Washington. Under Article V of the Constitution, a proposed amendment becomes part of the Constitution once three-fourths of the states ratify it. On December 6, 1865, Georgia became the 27th state to ratify, clearing that threshold.
Twelve days later, on December 18, 1865, Secretary of State William Seward issued the formal Proclamation of Adoption, certifying the amendment as a valid part of the Constitution and listing the 27 ratifying states. The original proclamation is housed within the Department of State’s records. Without the individual state certificates, the federal government could not have officially verified compliance with Article V, which makes those certificates essential links in the chain of legal authority even though they are less well known than the enrolled resolution.
The Emancipation Proclamation Is Related but Not the Same
The Emancipation Proclamation, effective January 1, 1863, is often grouped with 13th Amendment materials and is held in the National Archives as a three-page original. It is not a primary source for the amendment itself. The proclamation applied only to states in rebellion, left slavery untouched in loyal border states like Kentucky and Delaware, and carved out exceptions for parts of the Confederacy already under Union military control. As a wartime executive order grounded in the president’s commander-in-chief authority, it depended on military victory and was vulnerable to reversal by a future president or a postwar court. That legal fragility is precisely what made a constitutional amendment necessary, so the proclamation belongs in the research file as context rather than as a source for the amendment’s own text or adoption.
Enforcement-Era Statutes as Primary Sources
Congress used its Section 2 power quickly, and the first statutes passed under that authority are themselves primary sources for how the amendment was understood by the Congress that had just proposed it.
The Civil Rights Act of 1866 guaranteed that people of all races would have equal rights to make and enforce contracts, hold property, and access the courts. President Andrew Johnson vetoed the bill, arguing that it exceeded congressional authority; Congress overrode the veto. Portions of the act survive in the modern federal code at 42 U.S.C. §§ 1981–1982.
The Peonage Act of 1867, codified at 42 U.S.C. § 1994, abolished “the holding of any person to service or labor under the system known as peonage” in every state and territory and voided any state law that attempted to enforce it. In Bailey v. Alabama (1911), the Supreme Court used this statute alongside the amendment to hold that “the words ‘involuntary servitude’ have a larger meaning than slavery.”
Where To Access Each Source
Nearly every document above is publicly available, digitally or in person:
- The enrolled joint resolution: National Archives, Record Group 11, with a digital version in the Milestone Documents collection.
- The ceremonial signed copy: Library of Congress, Manuscript Division.
- Congressional Globe volumes for the 38th Congress: browsable by date and session on Congress.gov.
- Senate Joint Resolution 16, committee reports, and related legislative materials: Library of Congress research guide dedicated to the Thirteenth Amendment.
- State ratification certificates and Seward’s Proclamation of Adoption: Department of State records.
- Authoritative constitutional text with scholarly annotation: constitution.congress.gov and the Legal Information Institute at Cornell Law.
Working from these originals, rather than from later summaries, is what allows a researcher to speak precisely about what the amendment says, how it was adopted, and how the Congress that wrote it began to enforce it.
