The tribal town of Hitchiti first appeared in Spanish reports (as Ahachito) in 1675 as part of the Apalachicola Province along the Chattahoochee River. In the first half of the 17th century, a number of towns were situated along of the Chattahoochee River in
Alabama and Georgia, from the south of the falls at present-day
Columbus to
Barbour County, Alabama. Archaeological evidence indicates that the material culture of the 17th century lower Chattahoochee region had developed in place over several centuries. The ancestors of at least some of the people in the area may have been there as early as 12,000 years ago. A variant of the
Lamar regional culture, with influences from the
Fort Walton culture to the south, developed in the towns along the Chattahoochee between 1300 and 1400. A major change in ceramic types at sites along the Chattahoochee occurred between 1550 and 1650. There is also evidence of a large drop in the population in the area. The
de Soto expedition in the 1540s did not enter the Chattahoochee Valley, but appears to have caused many deaths there due to epidemics of
European and African diseases introduced by the
Spaniards. Some archaeologists state that only two population centers survived along the Chattahoochee in the late 16th century, situated on opposite sides of the river south of the falls at Columbus. Both sites had large
platform mounds, and may have served as ceremonial centers. While some archaeologists believe that some sites along the Chattahoochee remained stable population centers, and became sites of later population expansion, other archaeologists believe that there were significant influxes of other people into the Chattahoochee Valley, changing the material culture of the area.
Muscogee language-speaking people from the
Coosa and
Tallapoosa areas in Alabama may have moved into the Chattahoochee valley during the middle part of the 17th century. Folklore of the Lower Towns of the Muscogee Confederacy supports an interpretation of Muscogee-speaking immigrants joining a Hitchiti-speaking resident population, with the Chattahoochee River area including both Hitchiti- and Muscogee-speaking towns by the later 16th century. Speakers of the
Koasati language,
Apalachee people, and people known as
Chisca or
Yuchi also settled in the Chattahoochee towns in the later 17th century. John Worth placed the town of Hitchiti on the eastern (Georgia) side of the Chattahoochee River in the late 17th century, possibly at
archaeological site 9Ce1 in
Chattahoochee County, Georgia. That site was just south of the Muscogee-speaking towns of
Coweta,
Cusseta, and Kolomi. ==On Ochese Creek==
