Knox County was created after the American Revolutionary War on June 11, 1792, by Governor William Blount from parts of Greene and Hawkins counties. It was one of the few counties created when this area was still known as the Southwest Territory. It is one of nine United States counties named for American Revolutionary War general Henry Knox who was also appointed as the first United States Secretary of War. As the population increased, parts of Knox County were taken out to form Blount, Anderson, Roane, and Union counties from 1795 to 1850. The county today has a total area of 526 square miles and a population count of 470,313 residents.
