History

Formed in 1819 from Roane County

An old deed may name a county that no longer exists, or a boundary that has since moved.

Monroe County was created from Roane County on November 13, 1819. Throughout the 19th century, Monroe County's boundaries were adjusted through exchanges and gains from neighboring counties including Roane, Blount, McMinn, and Polk.

Boundary changes from the Newberry Library, Atlas of Historical County Boundaries; the 5 that matter most are shown first.
