That Constitution was ordained and established by the people of the United States, through the action, in each State, of those persons who were qualified by its laws to act thereon, in behalf of themselves and all other citizens of that State. In some of the States, as we have seen, colored persons were among those qualified by law to act on this subject. These colored persons were not only included in the body of "the people of the United States," by whom the Constitution was ordained and established, but in at least five of the States they had the power to act, and doubtless did act, by their suffrages, upon the question of its adoption. It would be strange, if we were to find in that instrument anything which deprived of their citizenship any part of the people of the United States who were among those by whom it was established. I can find nothing in the Constitution which, _proprio vigore_, deprives of their citizenship any class of persons who were citizens of the United States at the time of its adoption, or who should be native-born citizens of any State after its adoption; nor any power enabling Congress to disfranchise persons born on the soil of any State, and entitled to citizenship of such State by its Constitution and laws. And my opinion is, that, under the Constitution of the United States, every free person born on the soil of a State, who is a citizen of that State by force of its Constitution or laws, is also a citizen of the United States. I will proceed to state the grounds of that opinion. The first section of the second article of the Constitution uses the language, "a natural-born citizen." It thus assumes that citizenship may be acquired by birth. Undoubtedly, this language of the Constitution was used in reference to that principle of public law, well understood in this country at the time of the adoption of the Constitution, which referred citizenship to the place of birth. At the Declaration of Independence, and ever since, the received general doctrine has been, in conformity with the common law, that free persons born within either of the colonies were subjects of the King; that by the Declaration of Independence, and the consequent acquisition of sovereignty by the several States, all such persons ceased to be subjects, and became citizens of the several States, except so far as some of them were disfranchised by the legislative power of the States, or availed themselves, seasonably, of the right to adhere to the British Crown in the civil contest, and thus to continue British subjects (McIlvain _v._ Coxe's Lessee, 4 Cranch, 209; Inglis _v._ Sailors' Snug Harbor, 3 Peters, p. 99; Shanks _v._ Dupont, Ibid, p. 242.) The Constitution having recognised the rule that persons born within the several States are citizens of the United States, one of four things must be true: _First._ That the Constitution itself has described what native-born persons shall or shall not be citizens of the United States; or,
