The Thirteenth Amendment (Amendment XIII) to the United States Constitution abolished slavery and involuntary servitude, except as punishment for a crime. The amendment was passed by the Senate on April 8, 1864, by the House of Representatives on January 31, 1865, and ratified by the required 27 of the then 36 states on December 6, 1865, and proclaimed on December 18. It was the first of the three Reconstruction Amendments adopted following the American Civil War.
President Abraham Lincoln's Emancipation Proclamation, effective on January 1, 1863, declared that the enslaved in Confederate-controlled areas (and thus almost all slaves) were free. When they escaped to Union lines or federal forces (including now-former slaves) advanced south, emancipation occurred without any compensation to the former owners. Texas was the last Confederate-slave territory, where enforcement of the proclamation was declared on June 19, 1865. In the slave-owning areas controlled by Union forces on January 1, 1863, state action was used to abolish slavery. The exceptions were Kentucky and Delaware, and to a limited extent New Jersey, where chattel slavery and indentured servitude were finally ended by the Thirteenth Amendment in December 1865.
In contrast to the other Reconstruction Amendments, the Thirteenth Amendment has rarely been cited in case law, but it has been used to strike down peonage and some race-based discrimination as "badges and incidents of slavery". The Thirteenth Amendment has also been invoked to empower Congress to make laws against modern forms of slavery, such as sex trafficking.
From its inception in 1776, the United States was divided into states that allowed slavery and states that prohibited it. Slavery was implicitly recognized in the original Constitution in provisions such as the Three-fifths Compromise (Article I, Section 2, Clause 3), which provided that three-fifths of each state's enslaved population ("other persons") was to be added to its free population for the purposes of apportioning seats in the United States House of Representatives, its number of Electoral votes, and direct taxes among the states. The Fugitive Slave Clause (Article IV, Section 2, Clause 3) provided that slaves held under the laws of one state who escaped to another state did not become free, but remained slaves.
Though three million Confederate slaves were eventually freed as a result of Lincoln's Emancipation Proclamation, their postwar status was uncertain. To ensure that abolition was beyond legal challenge, an amendment to the Constitution to that effect was drafted. On April 8, 1864, the Senate passed an amendment to abolish slavery. After one unsuccessful vote and extensive legislative maneuvering by the Lincoln administration, the House followed suit on January 31, 1865. The measure was swiftly ratified by nearly all Northern states, along with a sufficient number of border states up to the assassination of President Lincoln. However, the approval came via his successor, President Andrew Johnson, who encouraged the "reconstructed" Southern states of Alabama, North Carolina, and Georgia to agree, which brought the count to 27 states, leading to its adoption before the end of 1865.
Though the Amendment abolished slavery throughout the United States, some black Americans, particularly in the South, were subjected to other forms of involuntary labor, such as under the Black Codes, white supremacist violence, and selective enforcement of statutes, as well as other disabilities. Many such abuses were given cover by the Amendment's penal labor exclusion, discussed below.
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.[1]
Slavery existed and was legal in the United States of America upon its founding in 1776. It was established by European colonization in all of the original thirteen American colonies of British America. Prior to the Thirteenth Amendment, the United States Constitution did not expressly use the words slave or slavery but included several provisions about unfree persons. The Three-Fifths Compromise, Article I, Section 2, Clause 3 of the Constitution, allocated Congressional representation based "on the whole Number of free Persons" and "three-fifths of all other Persons". This clause was a compromise between Southern politicians who wished for enslaved African-Americans to be counted as 'persons' for congressional representation and Northern politicians rejecting these out of concern of too much power for the South, because representation in the new Congress would be based on population in contrast to the one-vote-for-one-state principle in the earlier Continental Congress.[3] Under the Fugitive Slave Clause, Article IV, Section 2, Clause 3, "No person held to Service or Labour in one State" would be freed by escaping to another. Article I, Section 9, Clause 1 allowed Congress to pass legislation outlawing the "Importation of Persons", which would not be passed until 1808. However, for purposes of the Fifth Amendment—which states that "No person shall ... be deprived of life, liberty, or property, without due process of law"—slaves were understood as property.[4] Although abolitionists used the Fifth Amendment to argue against slavery, it became part of the legal basis in Dred Scott v. Sandford (1857) for treating slaves as property.[5]
Stimulated by the philosophy of the Declaration of Independence, between 1777 and 1804 every Northern state provided for the immediate or gradual abolition of slavery. (Slavery was never legal in Vermont; it was prohibited in the 1777 constitution creating Vermont, to become the fourteenth state.) Most of the slaves who were emancipated by such legislation were household servants. No Southern state did so, and the enslaved population of the South continued to grow, peaking at almost four million in 1861. An abolitionist movement, headed by such figures as William Lloyd Garrison, Theodore Dwight Weld, and Angelina Grimké, grew in strength in the North, calling for the immediate end of slavery nationwide and exacerbating tensions between North and South. The American Colonization Society, an alliance between abolitionists who felt the "races" should be kept separated and slaveholders who feared the presence of freed blacks would encourage slave rebellions, called for the emigration of both free blacks and slaves to Africa, where they would establish independent colonies. Its views were endorsed by politicians such as Henry Clay, who feared that the American abolitionist movement would provoke a civil war.[6] Proposals to eliminate slavery by constitutional amendment were introduced by Representative Arthur Livermore in 1818 and by John Quincy Adams in 1839, but failed to gain significant traction.[7]
As the country continued to expand, the issue of slavery in its new territories became the dominant national issue. The senatorial votes of new states could break the deadlock in the Senate over slavery. The Southern position was that slaves were property and therefore could be moved to the territories like all other forms of property.
