No States were involved in the Revolutionary War. Heh heh. To be technical. Always trying to be of help.
You’re correct, and also it is the case that Tennessee was not a state at all until right around the formation of actual states.
In fact, the area was technically controlled by North Carolina, but Tennessee wasn’t even part of the Continental Congress.
The Overmountain men were settlers in the area which would be called the State of Tennessee.
As of July 4, 1776, the former colonies became states.
