Tennessee is the 16th State Admitted to the Union
Eight counties of western North Carolina (and now part of Tennessee) broke off from that state in the late 1780s and formed the abortive State of Franklin.
Efforts to obtain admission to the Union failed, and the counties had re-joined North Carolina by 1790. North Carolina ceded the area to the federal government in 1790, after which it was organized into the Southwest Territory. In an effort to encourage settlers to move west into the new territory of Tennessee, in 1787 the mother state of North Carolina ordered a road to be cut to take settlers into the Cumberland Settlements—from the south end of Clinch Mountain (in East Tennessee) to French Lick (Nashville). The Trace was called the “North Carolina Road” or “Avery’s Trace,” and sometimes “The Wilderness Road (although it should not be confused with Daniel Boone's "Wilderness Road" through Cumberland Gap).
Tennessee was admitted to the Union in 1796 as the 16th state. The state boundaries, according to the Constitution of the State of Tennessee, Article I, Section 31, stated that the beginning point for identifying the boundary was the extreme height of the Stone Mountain, at the place where the line of Virginia intersects it, and basically ran the extreme heights of mountain chains through the Appalachian Mountains separating North Carolina from Tennessee past the Indian towns of Cowee and Old Chota, thence along the main ridge of the said mountain (Unicoi Mountain) to the southern boundary of the state; all the territory, lands and waters lying west of said line are included in the boundaries and limits of the newly formed state of Tennessee. Part of the provision also stated that the limits and jurisdiction of the state would include future land acquisition, referencing possible land trade with other states, or the acquisition of territory from west of the Mississippi River.
