How did tennesse become a state?

North Carolina. The North Carolina colonial charter actually gave the state a claim which extended all the way to the Pacific Ocean. I live in Buncombe County NC, in the western end of the state. At that time Buncombe was the westernmost NC county, and if you wanted to file a deed to land anywhere in what is Tennessee today, you had to file it in the Buncombe County Courthouse, until Tennessee was created in 1796.
