The above account of slavery and its modifications will be found in strictest conformity with the Institutes of Justinian. Thus, book 1st, title 3d, it is said: "The first general division of persons in respect to their rights is into freemen and slaves." The same title, sec. 4th: "Slaves are born such, or become so. They are born such of bondwomen; they become so either by the law of nations, as by capture, or by the civil law." Section 5th: "In the condition of slaves there is no diversity; but among free persons there are many. Thus some are ingenui or freemen, others libertini or freedmen."

Tit. 4th. De Ingenuis.—"A freeman is one who is born free by being born in matrimony, of parents who both are free, or both freed; or of parents one free and the other freed. But one born of a free mother, although the father be a slave or unknown, is free."

Tit. 5th. De Libertinis.—"Freedmen are those who have been manumitted from just servitude."

Section third of the same title states that "freedmen were formerly distinguished by a threefold division." But the emperor proceeds to say: "Our piety leading us to reduce all things into a better state, we have amended our laws, and re-established the ancient usage; for anciently liberty was simple and undivided—that is, was conferred upon the slave as his manumittor possessed it, admitting this single difference, that the person manumitted became only a freed man, although his manumittor was a free man." And he further declares: "We have made all freed men in general become citizens of Rome, regarding neither the age of the manumitted, nor the manumittor, nor the ancient forms of manumission. We have also introduced many new methods by which slaves may become Roman citizens."

By the references above given it is shown, from the nature and objects of civil and political associations, and upon the direct authority of history, that citizenship was not conferred by the simple fact of emancipation, but that such a result was deduced therefrom in violation of the fundamental principles of free political association; by the exertion of despotic will to establish, under a false and misapplied denomination, one equal and universal slavery; and to effect this result required the exertions of absolute power—of a power both in theory and practice, being in its most plenary acceptation the sovereignty, the State itself—it could not be produced by a less or inferior authority, much less by the will or the act of one who, with reference to civil and political rights, was himself a slave. The master might abdicate or abandon his interest or ownership in his property, but his act would be a mere abandonment. It seems to involve an absurdity to impute to it the investiture of rights which the sovereignty alone had power to impart. There is not perhaps a community in which slavery is recognised, in which the power of emancipation and the modes of its exercise are not regulated by law—that is, by the sovereign authority; and none can fail to comprehend the necessity for such regulation, for the preservation of order, and even of political and social existence.

By the argument for the plaintiff in error, a power equally despotic is vested in every member of the association, and the most obscure or unworthy individual it comprises may arbitrarily invade and derange its most deliberate and solemn ordinances. At assumptions anomalous as these, so fraught with mischief and ruin, the mind at once is revolted, and goes directly to the conclusions, that to change or to abolish a fundamental principle of the society, must be the act of the society itself—of the sovereignty; and that none other can admit to a participation of that high attribute. It may further expose the character of the argument urged for the plaintiff, to point out some of the revolting consequences which it would authorize. If that argument possesses any integrity, it asserts the power in any citizen, or quasi citizen, or a resident foreigner of any one of the States, from a motive either of corruption or caprice, not only to infract the inherent and necessary authority of such State, but also materially to interfere with the organization of the Federal Government, and with the authority of the separate and independent States. He may emancipate his negro slave, by which process he first transforms that slave into a citizen of his own State; he may next, under color of article fourth, section second, of the Constitution of the United States, obtrude him, and on terms of civil and political equality, upon any and every State in this Union, in defiance of all regulations of necessity or policy, ordained by those States for their internal happiness or safety. Nay, more: this manumitted slave may, by a proceeding springing from the will or act of his master alone, be mixed up with the institutions of the Federal Government, to which he is not a party, and in opposition to the laws of that Government which, in authorizing the extension by naturalization of the rights and immunities of citizens of the United States to those not originally parties to the Federal compact, have restricted that boon to free white aliens alone. If the rights and immunities connected with or practiced under the institutions of the United States can by any indirection be claimed or deduced from sources or modes other than the Constitution and laws of the United States, it follows that the power of naturalization vested in Congress is not exclusive—that it has in effect no existence, but is repealed or abrogated.

But it has been strangely contended that the jurisdiction of the Circuit Court might be maintained upon the ground that the plaintiff was a resident of Missouri, and that, for the purpose of vesting the court with jurisdiction over the parties, residence within the State was sufficient.

The first, and to my mind a conclusive reply to this singular argument is presented in the fact, that the language of the Constitution restricts the jurisdiction of the courts to cases in which the parties shall be citizens, and is entirely silent with respect to residence. A second answer to this strange and latitudinous notion is, that it so far stultifies the sages by whom the Constitution was framed, as to impute to them ignorance of the material distinction existing between citizenship and mere residence or domicil, and of the well-known facts, that a person confessedly an alien may be permitted to reside in a country in which he can possess no civil or political rights, or of which he is neither a citizen nor subject; and that for certain purposes a man may have a domicil in different countries, in no one of which he is an actual personal resident.

The correct conclusions upon the question here considered would seem to be these:

That in the establishment of the several communities now the States of this Union, and in the formation of the Federal Government, the African was not deemed politically a person. He was regarded and owned in every State in the Union as property merely, and as such was not and could not be a party or an actor, much less a peer in any compact or form of government established by the States or the United States. That if, since the adoption of the State Governments, he has been or could have been elevated to the possession of political rights or powers, this result could have been effected by no authority less potent than that of the sovereignty—the State—exerted to that end, either in the form of legislation, or in some other mode of operation. It could certainly never have been accomplished by the will of an individual operating independently of the sovereign power, and even contravening and controlling that power. That so far as rights and immunities appertaining to citizens have been defined and secured by the Constitution and laws of the United States, the African race is not and never was recognised either by the language or purposes of the former; and it has been expressly excluded by every act of Congress providing for the creation of citizens by naturalization, these laws, as has already been remarked, being restricted to free white aliens exclusively.
