William Bean, traditionally recognized as Tennessee's first settler, built his cabin along Boone's Creek near Johnson City in 1769. In the 1780s, Colonel John Tipton (1730–1813) established a farm (now the Tipton-Haynes State Historic Site) just outside what is now Johnson City. During the State of Franklin movement, Tipton was a leader of the loyalist faction, residents of the region who wanted to remain part of North Carolina rather than form a separate state. In February 1788, an armed engagement took place at Tipton's farm between Tipton and his men and the forces led by John Sevier, the leader of the Franklin faction. Founded in 1856 by Henry Johnson as a railroad station called "Johnson's Depot", Johnson City became a major rail hub for the Southeast, as three railway lines crossed in the downtown area.
