Fort Southwest Point at Kingston, Tennessee, occupied from 1797 to 1811, stood at a strategic frontier junction where major travel routes, the Tennessee and Clinch rivers, and the boundary between U.S. and Cherokee lands converged. Evolving from an earlier blockhouse and first known as Fort Butler, it became both a military post and a migration waystation, enforcing treaty lines while also serving U.S.-Cherokee negotiations through Cherokee Agent Return J. Meigs. Its military importance declined as the frontier moved south. Archaeology has reconstructed much of its layout and also revealed far older Native habitation, underscoring the site's lasting importance to early Tennessee settlement and diplomacy.
