Here’s a short history of the State of Scott, one of many pro-Union counties that rebelled against the rebellion. There’s a little more to read on the link – worth a few minutes of your time.
The State of Scott was the result of a secessionist movement by Scott County in the Eastern Division of Tennessee, which officially passed a proclamation during the American Civil War to secede from Tennessee and form the Free and Independent State of Scott in protest of the states separation from the United States. Scott became an enclave community of the Union within Tennessee. Although its edict had never been officially recognized by any government, the county didnt officially rescind its act of secession until 1986.
