The Fugitive Slave Act of 1850: Annotated
The five bills collectively known as The Compromise of 1850 were signed into law by US President Millard Fillmore in an effort to continue the union of the states in the face of growing divisions over the South’s push for the expansion of slavery.
Legal historian Paul Finkelman describes it as “the most massive ‘compromise’ ever over slavery,” one that
turned out to be more one-sided than any other compromises over slavery since the adoption of the Constitution. […] The legislation…was, in the end, overwhelmingly proslavery. It was an appeasement of the most radical proslavery men, and gave virtually nothing to the North or to freedom.
The last of the five bills to be signed, the Fugitive Slave Act, was the one least fought over by Congress and the worst enacted. As Finkelman writes, it was “one of the most repressive and unfair statutes ever adopted by the United States.” It removed access to the most basic of American constitutional rights, that of habeas corpus, from the enslaved (despite that same Constitution guaranteeing it, with the only exceptions made in “cases of rebellion or invasion [when] the public safety may require it”).
It allowed for the word of two men given to a US Commissioner, an official dedicated to hearings and judgements concerning “fugitives from labor,” to serve as sufficient evidence that a Black person, freed or enslaved, was a fugitive and could be kidnapped back to the South (not that this did happen prior to 1850, as evidenced by Solomon Northrup’s testimony in his Twelve Years A Slave.)
It incentivized Commissioners to find in favor of slave catchers: they received $10 for each person renditioned (approximately $410 in 2025) and $5 for those released.
It commanded Northern law enforcement and “all good citizens…to aid and assist in the prompt and efficient execution of this law” and set jail terms and fines for those who would aid fugitives or intervene in their arrests.
And it used the US Marshals to track, arrest, and return fugitives from Southern bondage.
Two years after the passage of the Fugitive Slave Act, Frederick Douglass fiercely condemned it in his speech, “What to the Slave is the Fourth of July?”
“By an act of the American Congress, not yet two years old,” he argued,
slavery has been nationalized in its most horrible and revolting form. By that act, Mason & Dixon’s line has been obliterated; New York has become as Virginia; and the power to hold, hunt, and sell men, women, and children as slaves remains no longer a mere state institution, but is now an institution of the whole United States. […] By that most foul and fiendish of all human decrees, the liberty and person of every man are put in peril. Your broad republican domain is hunting ground for men. Not for thieves and robbers, enemies of society, merely, but for men guilty of no crime. Your lawmakers have commanded all good citizens to engage in this hellish sport. Your President, your Secretary of State, your lords, nobles and ecclesiastics enforce, as a duty you owe to your free and glorious country, and to your God, that you do this accursed thing.
Rather than helping to keep the country together, the 1850 Compromise, made by legislators often hailed as heroic for their efforts, only managed to further anger Northern states while encouraging Southern representatives to increase slavery’s reach into new territories and states. The passage of the Kansas-Nebraska Act in 1854, nullifying the Missouri Compromise and replacing the ban on slavery with “popular sovereignty,” accelerated the oncoming confrontation, with “Bleeding Kansas” as a precursor battleground (as well as the floor of the House of Representatives).
Out of the conflict came the new anti-slavery Republican party, whose first Presidential candidate, John C. Fremont, did well in New England and the Midwest, but lost to James Buchanan in 1856. With Abraham Lincoln on the ballot in 1860, they won. Six weeks later, South Carolina issued their declaration of secession, explaining that
[f]or twenty-five years this agitation has been steadily increasing, until it has now secured to its aid the power of the common Government. Observing the forms of the Constitution, a sectional party has found within that Article establishing the Executive Department, the means of subverting the Constitution itself. A geographical line has been drawn across the Union, and all the States north of that line have united in the election of a man to the high office of President of the United States, whose opinions and purposes are hostile to slavery. He is to be entrusted with the administration of the common Government, because he has declared that that “Government cannot endure permanently half slave, half free,” and that the public mind must rest in the belief that slavery is in the course of ultimate extinction.
The Emancipation Proclamation and the North’s victory in the Civil War moved the Fugitive Slave Act from law to a part of a history that some states (and by Executive Order, the country as a whole) are still attempting to legislate away. Recently, however, legal scholars, historians, and journalists writing on the Fugitive Slave Law have examined its contemporary influence on, and parallels to, present-day immigration law. The work of Karla M. McKanders, Sandra L. Rierson, and others have explained how the denial of due process, lack of access to legal assistance, some states’ cooperation with Immigration & Customs Enforcement agents, and the similar tactics of separation of families, seizure, and rendition of individuals echo the worst of the Fugitive Slave Act’s destruction.
Reflecting on the failures of the men who wrote and supported the Fugitive Slave Act, Finkelman observes that
[b]etween 1850 and 1861, approximately one thousand [Black Americans] would be returned to bondage under the law. Because southerners estimated that more than ten thousand escaped in that time—and many more were already in the North—the law hardly gave the South what it needed. The decade was punctuated by rescues and other kinds of resistance. Fillmore, Webster, Clay, and the others who supported the law never expected white northerners to break the law to protect [B]lack freedom, though that happened sporadically throughout the decade. In trials, northern juries would almost always refuse to convict men charged with interfering with the law. Southerners, and their northern allies in Congress, probably assumed that [Black people] were irrelevant to the political equation. Doubtless their own racist assumptions made them believe that [B]lacks were not “manly” enough to fight for their own liberty. They were wrong.

Chap. LX. — An Act to amend, and supplementary to, the Act entitled “An Act respecting Fugitives from Justice, and Persons escaping from the Service of their Masters,” approved February twelfth, one thousand seven hundred and ninety-three.
Be it enacted by the Senate and House of Representatives of the United States of America in congress assembled, That the persons who have been, or may hereafter be, appointed commissioners, in virtue of any act of Congress, by the Circuit Courts of the United States, and who, in consequence of such appointment, are authorized to exercise the powers that any justice of the peace, or other magistrate of any of the United States, may exercise in respect to offenders for any crime or offence against the United States, by arresting, imprisoning, or bailing the same under and by virtue of the thirty-third section of the act of the twenty-fourth of September seventeen hundred and eighty nine, entitled “An Act to establish the judicial courts of the United States,” shall be, and are hereby, authorized and required to exercise and discharge all the powers and duties conferred by this act.
Sec. 2. And be it further enacted, That the Superior Court of each organized Territory of the United States shall have the same power to appoint commissioners to take acknowledgements of bail and affidavits, and to take depositions of witnesses in civil causes, which is now possessed by the Circuit Court of the United States; and all commissioners who shall hereafter be appointed for such purposes by the Superior Court of any organized Territory of the United States, shall possess all the powers, and exercise all the duties, conferred by law upon the commissioners appointed by the Circuit Courts of the United States for similar purposes, and shall moreover exercise and discharge all the powers and duties conferred by this act.
Sec. 3. And be it further enacted, That the Circuit Courts of the United States, and the Superior Courts of each organized Territory of the United States, shall from time to time enlarge the number of commissioners, with a view to afford reasonable facilities to reclaim fugitives from labor, and to the prompt discharge of the duties imposed by this act.
Sec. 4. And be it further enacted, That the commissioners above named shall have concurrent jurisdiction with the judges of the Circuit and District Courts of the United States, in their respective circuits and districts within the several States, and the judges of the Superior Courts of the Territories, severally and collectively, in termtime and vacation; and shall grant certificates to such claimants, upon satisfactory proof being made, with authority to take and remove such fugitives from service or labor, under the restrictions herein contained, to the State or Territory from which such persons may have escaped or fled.
Sec. 5. And be it further enacted, That it shall be the duty of all marshals and deputy marshals to obey and execute all warrants and precepts issued under the provisions of this act, when to them directed; and should any marshal or deputy marshal refuse to receive such warrant, or other process, when tendered, or to use all proper means diligently to execute the same, he shall, on conviction thereof, be fined in the sum of one thousand dollars, to the use of such claimant, on the motion of such claimant, by the Circuit or District Court for the district of such marshal; and after arrest of such fugitive, by such marshal or his deputy, or whilst at any time in his custody under the provisions of this act, should such fugitive escape, whether with or without the assent of such marshal or his deputy, such marshal shall be liable, on his official bond, to be prosecuted for the benefit of such claimant, for the full value of the service or labor of said fugitive in the State, Territory, or District whence he escaped: and the better to enable the said commissioners, when thus appointed, to execute their duties faithfully and efficiently, in conformity with the requirements of the Constitution of the United States and of this act, they are hereby authorized and empowered, within their counties respectively, to appoint, in writing under their hands, any one or more suitable persons, from time to time, to execute all such warrants and other process as may be issued by them in the lawful performance of their respective duties; with authority to such commissioners, or the persons to be appointed by them, to execute process as aforesaid, to summon and call to their aid the bystanders, or posse comitatus of the proper county, when necessary to ensure a faithful observance of the clause of the Constitution referred to, in conformity with the provisions of this act; and all good citizens are hereby commanded to aid and assist in the prompt and efficient execution of this law, whenever their services may be required, as aforesaid, for that purpose; and said warrants shall run, and be executed by said officers, any where in the State within which they are issued.
Sec. 6. And be it further enacted, That when a person held to service or labor in any State or Territory of the United States, has heretofore or shall hereafter escape into another State or Territory of the United States, the person or persons to whom such service or labor may be due, or his, her, or their agent or attorney, duly authorized, by power of attorney, in writing, acknowledged and certified under the seal of some legal officer or court of the State or Territory in which the same may be executed, may pursue and reclaim such fugitive person, either by procuring a warrant from some one of the courts, judges, or commissioners aforesaid, of the proper circuit, district, or county, for the apprehension of such fugitive from service or labor, or by seizing and arresting such fugitive, where the same can be done without process, and by taking, or causing such person to be taken, forthwith before such court, judge, or commissioner, whose duty it shall be to hear and determine the case of such claimant in a summary manner; and upon satisfactory proof being made, by deposition or affidavit, in writing, to be taken and certified by such court, judge, or commissioner, or by other satisfactory testimony, duly taken and certified by some court, magistrate, justice of the peace, or other legal officer authorized to administer an oath and take depositions under the laws of the State or Territory from which such person owing service or labor may have escaped, with a certificate of such magistracy or other authority, as aforesaid, with the seal of the proper court or officer thereto attached, which seal shall be sufficient to establish the competency of the proof, and with proof, also by affidavit, of the identity of the person whose service or labor is claimed to be due as aforesaid, that the person so arrested does in fact owe service or labor to the person or persons claiming him or her, in the State or Territory from which such fugitive may have escaped as aforesaid, and that said person escaped, to make out and deliver to such claimant, his or her agent or attorney, a certificate setting forth the substantial facts as to the service or labor due from such fugitive to the claimant, and of his or her escape from the State or Territory in which such service or labor was due, to the State or Territory in which he or she was arrested, with authority to such claimant, or his or her agent or attorney, to use such reasonable force and restraint as may be necessary, under the circumstances of the case, to take and remove such fugitive person back to the State or Territory whence he or she may have escaped as aforesaid. In no trial or hearing under this act shall the testimony of such alleged fugitive be admitted in evidence; and the certificates in this and the first [fourth] section mentioned, shall be conclusive of the right of the person or persons in whose favor granted, to remove such fugitive to the State or Territory from which he escaped, and shall prevent all molestation of such person or persons by any process issued by any court, judge, magistrate, or other person whomsoever.
Sec. 7. And be it further enacted, That any person who shall knowingly and willingly obstruct, hinder, or prevent such claimant, his agent or attorney, or any person or persons lawfully assisting him, her, or them, from arresting such a fugitive from service or labor, either with or without process as aforesaid, or shall rescue, or attempt to rescue, such fugitive from service or labor, from the custody of such claimant, his or her agent or attorney, or other person or persons lawfully assisting as aforesaid, when so arrested, pursuant to the authority herein given and declared; or shall aid, abet, or assist such person so owing service or labor as aforesaid, directly or indirectly, to escape from such claimant, his agent or attorney, or other person or persons legally authorized as aforesaid; or shall harbor or conceal such fugitive, so as to prevent the discovery and arrest of such person, after notice or knowledge of the fact that such person was a fugitive from service or labor as aforesaid, shall, for either of said offences, be subject to a fine not exceeding one thousand dollars, and imprisonment not exceeding six months, by indictment and conviction before the District Court of the United States for the district in which such offence may have been committed, or before the proper court of criminal jurisdiction, if committed within any one of the organized Territories of the United States; and shall moreover forfeit and pay, by way of civil damages to the party injured by such illegal conduct, the sum of one thousand dollars, for each fugitive so lost as aforesaid, to be recovered by action of debt, in any of the District or Territorial Courts aforesaid, within whose jurisdiction the said offence may have been committed.
Sec. 8. And be it further enacted, That the marshals, their deputies, and the clerks of the said District and Territorial Courts, shall be paid, for their services, the like fees as may be allowed to them for similar services in other cases; and where such services are rendered exclusively in the arrest, custody, and delivery of the fugitive to the claimant, his or her agent or attorney, or where such supposed fugitive may be discharged out of custody for the want of sufficient proof as aforesaid, then such fees are to be paid in the whole by such claimant, his agent or attorney; and in all cases where the proceedings are before a commissioner, he shall be entitled to a fee of ten dollars in full for his services in each case, upon the delivery of the said certificate to the claimant, his or her agent or attorney; or a fee of five dollars in cases where the proof shall not, in the opinion of such commissioner, warrant such certificate and delivery, inclusive of all services incident to such arrest and examination, to be paid, in either case, by the claimant, his or her agent or attorney. The person or persons authorized to execute the process to be issued by such commissioners for the arrest and detention of fugitives from service or labor as aforesaid, shall also be entitled to a fee of five dollars each for each person he or they may arrest and take before any such commissioner as aforesaid, at the instance and request of such claimant, with such other fees as may be deemed reasonable by such commissioner for such other additional services as may be necessarily performed by him or them; such as attending at the examination, keeping the fugitive in custody, and providing him with food and lodging during his detention, and until the final determination of such commissioner; and, in general, for performing such other duties as may be required by such claimant, his or her attorney or agent, or commissioner in the premises, such fees to be made up in conformity with the fees usually charged by the officers of the courts of justice within the proper district or county, as near as may be practicable, and paid by such claimants, their agents or attorneys, whether such supposed fugitives from service or labor be ordered to be delivered to such claimants by the final determination of such commissioners or not.
Sec. 9. And be it further enacted, That, upon affidavit made by the claimant of such fugitive, his agent or attorney, after such certificate has been issued, that he has reason to apprehend that such fugitive will be rescued by force from his or their possession before he can be taken beyond the limits of the State in which the arrest is made, it shall be the duty of the officer making the arrest to retain such fugitive in his custody, and to remove him to the State whence he fled, and there to deliver him to said claimant, his agent, or attorney. And to this end, the officer aforesaid is hereby authorized and required to employ so many persons as he may deem necessary to overcome such force, and to retain them in his service so long as circumstances may require. The said officer and his assistants, while so employed, to receive the same compensation, and to be allowed the same expenses, as are now allowed by law for transportation of criminals, to be certified by the judge of the district within which the arrest is made, and paid out of the treasury of the United States.
Sec. 10. And be it further enacted, That when any person held to service or labor in any State or Territory, or in the District of Columbia, shall escape therefrom, the party to whom such service or labor shall be due, his, her, or their agent or attorney, may apply to any court of record therein, or judge thereof in vacation, and make satisfactory proof to such court, or judge in vacation, of the escape aforesaid, and that the person escaping owed service or labor to such party. Whereupon the court shall cause a record to be made of the matters so proved, and also a general description of the person so escaping, with such convenient certainty as may be; and a transcript of such record, authenticated by the attestation of the clerk and of the seal of the said court, being produced in any other State, Territory, or district in which the person so escaping may be found, and being exhibited to any judge, commissioner, or other officer authorized by the law of the United States to cause persons escaping from service or labor to be delivered up, shall be held and taken to be full and conclusive evidence of the fact of escape, and that the service or labor of the person escaping is due to the party in such record mentioned. And upon the production by the said party of other and further evidence if necessary, either oral or by affidavit, in addition to what is contained in the said record of the identity of the person escaping, he or she shall be delivered up to the claimant. And the said court, commissioner, judge, or other person authorized by this act to grant certificates to claimants of fugitives, shall, upon the production of the record and other evidences aforesaid, grant to such claimant a certificate of his right to take any such person identified and proved to be owing service or labor as aforesaid, which certificate shall authorize such claimant to seize or arrest and transport such person to the State or Territory from which he escaped: Provided, That nothing herein contained shall be construed as requiring the production of a transcript of such record as evidence as aforesaid. But in its absence the claim shall be heard and determined upon other satisfactory proofs, competent in law.
