County Heritage Brief
Washington County
East Tennessee · County Seat: Jonesborough · Founded 1777
Home to Jonesborough, Tennessee's oldest town, founded 1779.
Why this county matters
Washington County in northeast Tennessee centers on Jonesborough, the state's oldest town (1779), and Johnson City, its largest city. The Watauga Association, one of the earliest self-governing bodies in the trans-Appalachian west, met in this area. The lost State of Franklin (1784-1788) had its capital in Jonesborough. The county is home to East Tennessee State University and the National Storytelling Festival. The region's railroad and iron industry history shaped its development through the 19th century.
