And if it was intended to secure these rights only to citizens of the United States, how has the Constitution here described such persons? Simply as citizens of each State. But, further: though, as I shall presently more fully state, I do not think the enjoyment of the elective franchise essential to citizenship, there can be no doubt it is one of the chiefest attributes of citizenship under the American Constitutions; and the just and constitutional possession of this right is decisive evidence of citizenship. The provisions made by a constitution on this subject must therefore be looked to as bearing directly on the question what persons are citizens under that constitution; and as been decisive, to this extent, that all such persons as are allowed by the Constitution to exercise the elective franchise, and thus to participate in the Government of the United States, must be deemed citizens of the United States. Here, again, the consideration presses itself upon us, that if there was designed to be a particular class of native-bom persons within the States, deriving their citizenship from the Constitution and laws of the United States, they should at least have been referred to as those by whom the President and House of Representatives were to be elected, and to whom they should be responsible. Instead of that, we again find this subject referred to the laws of the several States. The electors of President are to be appointed in such manner as the Legislature of each State may direct, and the qualifications of electors of members of the House of Representatives shall be the same as for electors of the most numerous branch of the State Legislature. Laying aside, then, the case of aliens, concerning which the Constitution of the United States has provided, and confining our view to free persons bom within the several States, we find that the Constitution has recognized the general principle of public law, that allegiance and citizenship depend on the place of birth; that it has not attempted practically to apply this principle by designating the particular classes of persons who should or should not come under it; that when we turn to the Constitution for an answer to the question, what free persons, born within the several States, are citizens of the United States, the only answer we can receive from any of its express provisions is, the citizens of the several States are to enjoy the privileges and immunities of citizens in every State, and their franchise as electors under the Constitution depends on their citizenship in the several States. Add to this, that the Constitution was ordained by the citizens of the several States; that they were "the people of the United States," for whom and whose posterity the government was declared in the preamble of the Constitution to be made; that each of them was "a citizen of the United States at the time of the adoption of the Constitution," within the meaning of those words in that instrument; that by them the government was to be and was in fact organized; and that no power is conferred on the Government of the Union to discriminate between them, or to disfranchise any of them — the necessary conclusion is, that those persons born within the several States, who, by force of their respective constitutions and laws, are citizens of the State, are thereby citizens of the United States. 93
