The legislation of the States therefore shows, in a manner not to be mistaken, the inferior and subject condition of that race at the time the Constitution was adopted, and long afterwards, throughout the thirteen States by which that instrument was framed; and it is hardly consistent with the respect due to these States, to suppose that they regarded at that time, as fellow-citizens and members of the sovereignty, a class of beings whom they had thus stigmatized; whom, as we are bound, out of respect to the State sovereignties, to assume they had deemed it just and necessary thus to stigmatize, and upon whom they had impressed such deep and enduring marks of inferiority and degradation; or, that when they met in convention to form the Constitution, they looked upon them as a portion of their constituents, or designed to include them in the provisions so carefully inserted for the security and protection of the liberties and rights of their citizens. It cannot be supposed that they intended to secure to them rights, and privileges, and rank, in the new political body throughout the Union, which every one of them denied within the limits of its own dominion. More especially, it cannot be believed that the large slaveholding States regarded them as included in the word citizens, or would have consented to a Constitution which might compel them to receive them in that character from another State. For if they were so received, and entitled to the privileges and immunities of citizens, it would exempt them from the operation of the special laws and from the police regulations which they considered to be necessary for their own safety. It would give to persons of the negro race, who were recognised as citizens in any one State of the Union, the right to enter every other State whenever they pleased, singly or in companies, without pass or passport, and without obstruction, to sojourn there as long as they pleased, to go where they pleased at every hour of the day or night without molestation, unless they committed some violation of law for which a white man would be punished; and it would give them the full liberty of speech in public and in private upon all subjects upon which its own citizens might speak; to hold public meetings upon political affairs, and to keep and carry arms wherever they went. And all of this would be done in the face of the subject race of the same color, both free and slaves, and inevitably producing discontent and insubordination among them, and endangering the peace and safety of the State.

It is impossible, it would seem, to believe that the great men of the slaveholding States, who took so large a share in framing the Constitution of the United States, and exercised so much influence in procuring its adoption, could have been so forgetful or regardless of their own safety and the safety of those who trusted and confided in them.

Besides, this want of foresight and care would have been utterly inconsistent with the caution displayed in providing for the admission of new members into this political family. For, when they gave to the citizens of each State the privileges and immunities of citizens in the several States, they at the same time took from the several States the power of naturalization, and confined that power exclusively to the Federal Government. No State was willing to permit another State to determine who should or should not be admitted as one of its citizens, and entitled to demand equal rights and privileges with their own people, within their own territories. The right of naturalization was therefore, with one accord, surrendered by the States, and confided to the Federal Government. And this power granted to Congress to establish an uniform rule of naturalization is, by the well-understood meaning of the word, confined to persons born in a foreign country, under a foreign Government. It is not a power to raise to the rank of a citizen any one born in the United States, who, from birth or parentage, by the laws of the country, belongs to an inferior and subordinate class. And when we find the States guarding themselves from the indiscreet or improper admission by other States of emigrants from other countries, by giving the power exclusively to Congress, we cannot fail to see that they could never have left with the States a much more important power—that is, the power of transforming into citizens a numerous class of persons, who in that character would be much more dangerous to the peace and safety of a large portion of the Union, than the few foreigners one of the States might improperly naturalize. The Constitution upon its adoption obviously took from the States all power by any subsequent legislation to introduce as a citizen into the political family of the United States any one, no matter where he was born, or what might be his character or condition; and it gave to Congress the power to confer this character upon those only who were born outside of the dominions of the United States. And no law of a State, therefore, passed since the Constitution was adopted, can give any right of citizenship outside of its own territory.

A clause similar to the one in the Constitution, in relation to the rights and immunities of citizens of one State in the other States, was contained in the Articles of Confederation. But there is a difference of language, which is worthy of note. The provision in the Articles of Confederation was, "that the free inhabitants of each of the States, paupers, vagabonds, and fugitives from justice, excepted, should be entitled to all the privileges and immunities of free citizens in the several States."

It will be observed, that under this Confederation, each State had the right to decide for itself, and in its own tribunals, whom it would acknowledge as a free inhabitant of another State. The term free inhabitant, in the generality of its terms, would certainly include one of the African race who had been manumitted. But no example, we think, can be found of his admission to all the privileges of citizenship in any State of the Union after these Articles were formed, and while they continued in force. And, notwithstanding the generality of the words "free inhabitants," it is very clear that, according to their accepted meaning in that day, they did not include the African race, whether free or not: for the fifth section of the ninth article provides that Congress should have the power "to agree upon the number of land forces to be raised, and to make requisitions from each State for its quota in proportion to the number of white inhabitants in such State, which requisition should be binding."

Words could hardly have been used which more strongly mark the line of distinction between the citizen and the subject; the free and the subjugated races. The latter were not even counted when the inhabitants of a State were to be embodied in proportion to its numbers for the general defence. And it cannot for a moment be supposed, that a class of persons thus separated and rejected from those who formed the sovereignty of the States, were yet intended to be included under the words "free inhabitants," in the preceding article, to whom privileges and immunities were so carefully secured in every State.

But although this clause of the Articles of Confederation is the same in principle with that inserted in the Constitution, yet the comprehensive word inhabitant, which might be construed to include an emancipated slave, is omitted; and the privilege is confined to citizens of the State. And this alteration in words would hardly have been made, unless a different meaning was intended to be conveyed, or a possible doubt removed. The just and fair inference is, that as this privilege was about to be placed under the protection of the General Government, and the words expounded by its tribunals, and all power in relation to it taken from the State and its courts, it was deemed prudent to describe with precision and caution the persons to whom this high privilege was given—and the word citizen was on that account substituted for the words free inhabitant. The word citizen excluded, and no doubt intended to exclude, foreigners who had not become citizens of some one of the States when the Constitution was adopted; and also every description of persons who were not fully recognised as citizens in the several States. This, upon any fair construction of the instruments to which we have referred, was evidently the object and purpose of this change of words.

To all this mass of proof we have still to add, that Congress has repeatedly legislated upon the same construction of the Constitution that we have given. Three laws, two of which were passed almost immediately after the Government went into operation, will be abundantly sufficient to show this. The two first are particularly worthy of notice, because many of the men who assisted in framing the Constitution, and took an active part in procuring its adoption, were then in the halls of legislation, and certainly understood what they meant when they used the words "people of the United States" and "citizen" in that well-considered instrument.

The first of these acts is the naturalization law, which was passed at the second session of the first Congress, March 26, 1790, and confines the right of becoming citizens "to aliens being free white persons."

Now, the Constitution does not limit the power of Congress in this respect to white persons. And they may, if they think proper, authorize the naturalization of any one, of any color, who was born under allegiance to another Government. But the language of the law above quoted, shows that citizenship at that time was perfectly understood to be confined to the white race; and that they alone constituted the sovereignty in the Government.
