This is certainly a very serious question, and one that now for the first time has been brought for decision before this court. But it is brought here by those who have a right to bring it, and it is our duty to meet it and decide it.

The question is simply this: Can a negro, whose ancestors were imported into this country, and sold as slaves, become a member of the political community formed and brought into existence by the Constitution of the United States, and as such become entitled to all the rights, and privileges, and immunities, guarantied by that instrument to the citizen? One of which rights is the privilege of suing in a court of the United States in the cases specified in the Constitution.

It will be observed, that the plea applies to that class of persons only whose ancestors were negroes of the African race, and imported into this country, and sold and held as slaves. The only matter in issue before the court, therefore, is, whether the descendants of such slaves, when they shall be emancipated, or who are born of parents who had become free before their birth, are citizens of a State, in the sense in which the word citizen is used in the Constitution of the United States. And this being the only matter in dispute on the pleadings, the court must be understood as speaking in this opinion of that class only, that is, of those persons who are the descendants of Africans who were imported into this country, and sold as slaves….

The words 'people of the United States' and 'citizens' are synonymous terms, and mean the same thing. They both describe the political body who, according to our republican institutions, form the sovereignty, and who hold the power and conduct the Government through their representatives. They are what we familiarly call the 'sovereign people,' and every citizen is one of this people, and a constituent member of this sovereignty. The question before us is, whether the class of persons described in the plea in abatement compose a portion of this people, and are constituent members of this sovereignty? We think they are not, and that they are not included, and were not intended to be included, under the word 'citizens' in the Constitution, and can therefore claim none of the rights and privileges which that instrument provides for and secures to citizens of the United States. On the contrary, they were at that time considered as a subordinate and inferior class of beings, who had been subjugated by the dominant race, and, whether emancipated or not, yet remained subject to their authority, and had no rights or privileges but such as those who held the power and the Government might choose to grant them….

In discussing this question, we must not confound the rights of citizenship which a State may confer within its own limits, and the rights of citizenship as a member of the Union. It does not by any means follow, because he has all the rights and privileges of a citizen of a State, that he must be a citizen of the United States. He may have all of the rights and privileges of the citizen of a State, and yet not be entitled to the rights and privileges of a citizen in any other State. For, previous to the adoption of the Constitution of the United States, every State had the undoubted right to confer on whomsoever it pleased the character of citizen, and to endow him with all its rights. But this character of course was confined to the boundaries of the State, and gave him no rights or privileges in other States beyond those secured to him by the laws of nations and the comity of States. Nor have the several States surrendered the power of conferring these rights and privileges by adopting the Constitution of the United States. Each State may still confer them upon an alien, or any one it thinks proper, or upon any class or description of persons; yet he would not be a citizen in the sense in which that word is used in the Constitution of the United States, nor entitled to sue as such in one of its courts, nor to the privileges and immunities of a citizen in the other States….

It is very clear, therefore, that no State can, by any act or law of its own, passed since the adoption of the Constitution, introduce a new member into the political community created by the Constitution of the United States. It cannot make him a member of this community by making him a member of its own. And for the same reason it cannot introduce any person, or description of persons, who were not intended to be embraced in this new political family, which the Constitution brought into existence, but were intended to be excluded from it.

The question then arises, whether the provisions of the Constitution, in relation to the personal rights and privileges to which the citizen of a State should be entitled, embraced the negro African race, at that time in this country, or who might afterwards be imported, who had then or should afterwards be made free in any State; and to put it in the power of a single State to make him a citizen of the United States, and endue him with the full rights of citizenship in every other State without their consent? Does the Constitution of the United States act upon him whenever he shall be made free under the laws of a State, and raised there to the rank of a citizen, and immediately clothe him with all the privileges of a citizen in every other State, and in its own courts?

In the opinion of the court, the legislation and histories of the times, and the language used in the Declaration of Independence, show, that neither the class of persons who had been imported as slaves, nor their descendants, whether they had become free or not, were then acknowledged as a part of the people, nor intended to be included in the general words used in that memorable instrument.

It is difficult at this day to realize the state of public opinion in relation to that unfortunate race, which prevailed in the civilized and enlightened portions of the world at the time of the Declaration of Independence, and when the Constitution of the United States was framed and adopted. But the public history of every European nation displays it in a manner too plain to be mistaken….

We refer to these historical facts for the purpose of showing the fixed opinions concerning that race, upon which the statesmen of that day spoke and acted. It is necessary to do this, in order to determine whether the general terms used in the Constitution of the United States, as to the rights of man and the rights of the people, was intended to include them, or to give to them or their posterity the benefit of any of its provisions.

The language of the Declaration of Independence is equally conclusive:

It begins by declaring that, 'when in the course of human events it becomes necessary for one people to dissolve the political bands which have connected them with another, and to assume among the powers of the earth the separate and equal station to which the laws of nature and nature's God entitle them, a decent respect for the opinions of mankind requires that they should declare the causes which impel them to the separation.'

It then proceeds to say: 'We hold these truths to be self-evident: that all men are created equal; that they are endowed by their Creator with certain unalienable rights; that among them is life, liberty, and the pursuit of happiness; that to secure these rights, Governments are instituted, deriving their just powers from the consent of the governed.'

The general words above quoted would seem to embrace the whole human family, and if they were used in a similar instrument at this day would be so understood. But it is too clear for dispute, that the enslaved African race were not intended to be included, and formed no part of the people who framed and adopted this declaration; for if the language, as understood in that day, would embrace them, the conduct of the distinguished men who framed the Declaration of Independence would have been utterly and flagrantly inconsistent with the principles they asserted; and instead of the sympathy of mankind, to which they so confidently appealed, they would have deserved and received universal rebuke and reprobation.

Yet the men who framed this declaration were great men-high in literary acquirements-high in their sense of honor, and incapable of asserting principles inconsistent with those on which they were acting. They perfectly understood the meaning of the language they used, and how it would be understood by others; and they knew that it would not in any part of the civilized world be supposed to embrace the negro race, which, by common consent, had been excluded from civilized Governments and the family of nations, and doomed to slavery. They spoke and acted according to the then established doctrines and principles, and in the ordinary language of the day, and no one misunderstood them. The unhappy black race were separated from the white by indelible marks, and laws long before established, and were never thought of or spoken of except as property, and when the claims of the owner or the profit of the trader were supposed to need protection.

This state of public opinion had undergone no change when the Constitution was adopted, as is equally evident from its provisions and language….

But there are two clauses in the Constitution which point directly and specifically to the negro race as a separate class of persons, and show clearly that they were not regarded as a portion of the people or citizens of the Government then formed.…

We proceed, therefore, to inquire whether the facts relied on by the plaintiff entitled him to his freedom….

The act of Congress, upon which the plaintiff relies, declares that slavery and involuntary servitude, except as a punishment for crime, shall be forever prohibited in all that part of the territory ceded by France, under the name of Louisiana, which lies north of thirty-six degrees thirty minutes north latitude, and not included within the limits of Missouri. And the difficulty which meets us at the threshold of this part of the inquiry is, whether Congress was authorized to pass this law under any of the powers granted to it by the Constitution; for if the authority is not given by that instrument, it is the duty of this court to declare it void and inoperative, and incapable of conferring freedom upon any one who is held as a slave under the have of any one of the states.

The counsel for the plaintiff has laid much stress upon that article in the Constitution which confers on Congress the power 'to dispose of and make all needful rules and regulations respecting the territory or other property belonging to the United States;' but, in the judgment of the court, that provision has no bearing on the present controversy, and the power there given, whatever it may be, is confined, and was intended to be confined, to the territory which at that time belonged to, or was claimed by, the United States, and was within their boundaries as settled by the treaty with Great Britain, and can have no influence upon a territory afterwards acquired from a foreign Government. It was a special provision for a known and particular territory, and to meet a present emergency, and nothing more….

… It may be safely assumed that citizens of the United States who migrate to a Territory belonging to the people of the United States, cannot be ruled as mere colonists, dependent upon the will of the General Government, and to be governed by any laws it may think proper to impose. The principle upon which our Governments rest, and upon which alone they continue to exist, is the union of States, sovereign and independent within their own limits in [60 U.S. 393, 448] their internal and domestic concerns, and bound together as one people by a General Government, possessing certain enumerated and restricted powers, delegated to it by the people of the several States, and exercising supreme authority within the scope of the powers granted to it, throughout the dominion of the United States. A power, therefore, in the General Government to obtain and hold colonies and dependent territories, over which they might legislate without restriction, would be inconsistent with its own existence in its present form. Whatever it acquires, it acquires for the benefit of the people of the several States who created it. It is their trustee acting for them, and charged with the duty of promoting the interests of the whole people of the Union in the exercise of the powers specifically granted….

But the power of Congress over the person or property of a citizen can never be a mere discretionary power under our Constitution and form of Government. The powers of the Government and the rights and privileges of the citizen are regulated and plainly defined by the Constitution itself. And when the Territory becomes a part of the United States, the Federal Government enters into possession in the character impressed upon it by those who created it. It enters upon it with its powers over the citizen strictly defined, and limited by the Constitution, from which it derives its own existence, and by virtue of which alone it continues to exist and act as a Government and sovereignty….

Upon these considerations, it is the opinion of the court that the act of Congress which prohibited a citizen from holding and owning property of this kind in the territory of the United States north of the line therein mentioned, is not warranted by the Constitution, and is therefore void; and that neither Dred Scott himself, nor any of his family, were made free by being carried into this territory; even if they had been carried there by the owner, with the intention of becoming a permanent resident….
