Sumner County was created in 1786, when Tennessee was still part of North Carolina. The county had been inhabited by Native Americans for centuries, as evidenced by Mississippian period mounds still visible at Castalian Springs. Longhunters traveled to the area as early as the 1760s, following Indian paths through the area. By the early 1780s, several outposts had been erected, most notably Mansker's Station, built by Kasper Mansker at modern Goodlettsville, and Bledsoe's Station, built by Isaac Bledsoe at Castalian Springs.
