Many early United States settlements in Tennessee and Mississippi were created along the Natchez Trace. Some of the most prominent were Washington, Mississippi (the old capital of Mississippi); "Old" Greenville, Mississippi (where Andrew Jackson conducted domestic slave trade); and Port Gibson, Mississippi. The Natchez Trace was used during the War of 1812 and the ensuing Creek War, as soldiers under Major General Andrew Jackson's command traveled southward to subdue the Red Sticks and to defend the country against invasion by the British.
