Fort Watauga, the first settlers' fort built west of the Alleghanies in 1770, was the place where patriots under Sevier, Shelby, and Campbell assembled on September 25, 1780, on their way to King's Mountain. Here, too, the Treaty of Sycamore Shoals was negotiated on March 19, 1775, under which Transylvania was acquired from the Cherokees.
