During the sitting of the convention which framed the Constitution, the Congress, which was in session, adopted the celebrated ordinance of 1787, for the government of the territory northwest of the Ohio river, in which ordinance was contained a prohibition of slavery in that territory forever, and also a provision for the recovery of slaves escaping into the territory similar to that incorporated into the Constitution. At the first session of the first Congress, under the new Constitution, an act was passed for the government of the territory northwest of the Ohio river, by which the ordinance of 1787 was recognized and confirmed. In 1787, South Carolina had surrendered her claim to all territory west of the present limits, and in 1790, North Carolina ceded to the United States that part of her territory which subsequently became the state of Tennessee, with a stipulation, "that no regulation made or to be made by Congress shall tend to the emancipation of slaves." In 1791, Vermont, formed out of part of the territory of New York, with the consent of the legislature of that state, was admitted into the Union as one of the states and came in without slavery, which was forbidden by her constitution. Kentucky (formed out of the territory of Virginia, south of the Ohio river, with the assent of her legislature) in 1792 was admitted into the Union, and came in with slavery as it existed in Virginia and with similar laws on the subject. In 1793, Congress passed an act to carry into effect the provision of the Constitution for the restitution of fugitive slaves, providing for their delivery to the owners by order of any United States judge, or any magistrate of the city, town or county where they might be arrested, on due proofs of ownership, etc. In 1796, Tennessee, formed out of the territory which had been ceded by North Carolina, was admitted into the Union, and came in with slavery as it existed in North Carolina and with similar laws in regard to it. In 1798, Georgia adopted a new Constitution, in which was a clause forbidding the importation of slaves from "Africa or any foreign country." In this same year Congress passed an act for the establishment of the Mississippi territory out of the territory acquired from Great Britain, which constituted that part of British West Florida lying between a line drawn due east from the mouth of the Yazoo to the Chattahoochie river and the 31st degree of latitude. The act provided for the government and organization of the Mississippi territory in every respect like the North Western territory, except that slavery was not to be prohibited, but an amendment was incorporated into the act without opposition, on motion of a representative from South Carolina, prohibiting the introduction of slaves into the territory from without the United States.
