The first settlers arrived in Franklin County in 1804. This group included six brothers named Jordan. They settled near the southeastern corner of the County, near modern Thompsonville. The first year they built a pole shed, covered with brush, chinked with mud, thatched with grass, and open to the south. They kept a fire burning outside the south face. This was called the Jordan Settlement.

In the winter of 1809, during Tecumseh's War, there was fear of attacks by Indians. Governor Edwards issued a call for the building of forts. Frank Jordan built two forts. The one at the settlement was called "Jordan's Fort". The second was several miles west. It was called "Frank's Fort", which eventually became West Frankfort.

Franklin County was formed in 1818 out of Gallatin and White Counties. It was named for Benjamin Franklin.
