The Constitution of the United States supplies the defect that existed in the articles of confederation, and has vested Congress, as has been stated, with ample powers on this important subject. Accordingly, the ordinance of 1787, passed by the old Congress, was ratified and confirmed by an act of the new Congress during their first session under the Constitution.
The State of Virginia, which ceded to the United States her claims to this territory, consented by her delegates in the old Congress to this ordinance—not only Virginia, but North Carolina, South Carolina, and Georgia, by the unanimous votes of their delegates in the old Congress, approved of the ordinance of 1787, by which slavery is forever abolished in the territory northwest of the river Ohio.
Without the votes of these States, the ordinance could not have passed; and there is no recollection of an opposition from any of these States to the act of confirmation, passed under the actual Constitution. Slavery had long been established in these States—the evil was felt in their institutions, laws, and habits, and could not easily or at once be abolished. But these votes so honorable to these States, satisfactorily demonstrate their unwillingness to permit the extension of slavery into the new States which might be admitted by Congress into the Union.
The States of Ohio, Indiana, and Illinois, on the northwest of the river Ohio, have been admitted by Congress into the Union, on the condition and conformably to the article of compact, contained in the ordinance of 1787, and by which it is declared that there shall be neither slavery nor involuntary servitude in any of the said States.
Although Congress possess the power of making the exclusion of slavery a part or condition of the act admitting a new State into the Union, they may, in special cases, and for sufficient reasons, forbear to exercise this power. Thus Kentucky and Vermont were admitted as new States into the Union, without making the abolition of slavery the condition of their admission. In Vermont, slavery never existed; her laws excluding the same. Kentucky was formed out of, and settled by, Virginia, and the inhabitants of Kentucky, equally with those of Virginia, by fair interpretation of the Constitution, were exempt from all such interference of Congress, as might disturb or impair the security of their property in slaves. The western territory of North Carolina and Georgia, having been partially granted and settled under the authority of these States, before the cession thereof to the United States, and these States being original parties to the Constitution which recognizes the existence of slavery, no measure restraining slavery could be applied by Congress to this territory. But to remove all doubt on this head, it was made a condition of the cession of this territory to the United States, that the ordinance of 1787, except the sixth article thereof, respecting slavery, should be applied to the same; and that the sixth article should not be so applied. Accordingly, the States of Tennessee, Mississippi, and Alabama, comprehending the territory ceded to the United States by North Carolina and Georgia, have been admitted as new States into the Union, without a provision, by which slavery shall be excluded from the same. According to this abstract of the proceedings of Congress in the admission of new States into the Union, of the eight new States within the original limits of the United States, four have been admitted without an article excluding slavery; three have been admitted on the condition that slavery should be excluded; and one admitted without such condition. In the few first cases, Congress were restrained from exercising the power to exclude slavery; in the next three, they exercised this power; and in the last, it was unnecessary to do so, slavery being excluded by the State Constitution.
The province of Louisiana, soon after its cession to the United States, was divided into two territories, comprehending such parts thereof as were contiguous to the river Mississippi, being the only parts of the province that were inhabited. The foreign language, laws, customs, and manners of the inhabitants, required the immediate and cautious attention of Congress, which, instead of extending, in the first instance, to these territories the ordinance of 1787, ordained special regulations for the government of the same. These regulations were from time to time revised and altered, as observation and experience showed to be expedient, and as was deemed most likely to encourage and promote those changes which would soonest qualify the inhabitants for self-government and admission into the Union. When the United States took possession of the province of Louisiana in 1804, it was estimated to contain 50,000 white inhabitants, 40,000 slaves, and 2,000 free persons of color.
More than four-fifths of the whites, and all the slaves, except about thirteen hundred, inhabited New Orleans and the adjacent territory; the residue, consisting of less than ten thousand whites, and about thirteen hundred slaves, were dispersed throughout the country now included in the Arkansas and Missouri territories. The greater part of the thirteen hundred slaves were in the Missouri territory, some of them having been removed thither from the old French settlements on the east side of the Mississippi, after the passing of the ordinance of 1787, by which slavery in those settlements was abolished.
In 1812, the territory of New Orleans, to which the ordinance of 1787, with the exception of certain parts thereof, had been previously extended, was permitted by Congress to form a Constitution and State Government, and admitted as a new State into the Union, by the name of Louisiana. The acts of Congress for these purposes, in addition to sundry important provisions respecting rivers and public lands, which are declared to be irrevocable unless by common consent, annex other terms and conditions, whereby it is established, not only that the Constitution of Louisiana should be republican, but that it should contain the fundamental principles of civil and religious liberty, that it should secure to the citizens the trial by jury in all criminal cases, and the privilege of the writ of habeas corpus according to the Constitution of the United States; and after its admission into the Union, that the laws which Louisiana might pass, should be promulgated; its records of every description preserved; and its judicial and legislative proceedings conducted in the language in which the laws and judicial proceedings of the United States are published and conducted.
Having annexed these new and extraordinary conditions to the act for the admission of Louisiana into the Union, Congress may, if they shall deem it expedient, annex the like conditions to the act for the admission of Missouri; and, moreover, as in the case of Ohio, Indiana, and Illinois, provide by an article for that purpose, that slavery shall not exist within the same.
