The county was created on October 25, 1819.[6] Hamilton County expanded to meet the state line with Georgia after absorbing parts of three different counties including Bledsoe, Marion, and Rhea. Part of the traditional Cherokee homeland, the county was created after the Cherokee signed a treaty in 1817 with the United States and ceded land north of the Hiwassee River. In the 21st century, Hamilton County is the eighth-highest income Tennessee location by per capita income ($26,588).
