and western North Carolina, and Tennessee. Chronologically this area became influenced by Mississippian culture later than the Middle Mississippian area (about 1000 CE as compared to 800 CE) to its northwest. It is believed that the peoples of this area adopted Mississippian traits from their northwestern neighbors. Typical settlements were located on riverine floodplains and included villages with defensive palisades enclosing platform mounds and residential areas. Etowah and Ocmulgee in Georgia are both prominent examples of major South Appalachian Mississippian settlements. Both include multiple large earthwork mounds serving a variety of functions. Villages with single platform mounds were more typical of the river valley settlements throughout the mountainous area of southwest North and South Carolina, and southeastern Tennessee that were known as the historic Cherokee homelands. In Western North Carolina for example; some 50 such mound sites in the eleven westernmost counties have been identified since the late 20th century, following increased research in this area of the Cherokee homeland. Caddoan Mississippian The Caddoan Mississippian area, a regional variant of the Mississippian culture, covered a large territory, including what is now eastern Oklahoma, western Arkansas, northeastern Texas, and northwestern Louisiana. Archaeological evidence has led to a scholarly consensus that the cultural continuity is unbroken from prehistory to the present, and that the Caddo and related Caddo language speakers in prehistoric times and at first European contact are the direct ancestors of the modern Caddo Nation of Oklahoma. The climate in this area was drier than areas in the eastern woodlands, hindering maize production, and the lower population on the plains to the west may have meant fewer neighboring competing chiefdoms to contend with. Major sites such as Spiro and the Battle Mound Site are in the Arkansas River and Red River Valleys, the largest and most fertile of the waterways in the Caddoan region, where maize agriculture would have been the most productive. The sites generally lacked wooden palisade fortifications often found in the major Middle Mississippian towns. Living on the western edge of the Mississippian world, the Caddoans may have faced fewer military threats from their neighbors. Their societies may also have had a somewhat lower level of social stratification. The Caddoan people were speakers of one of the many Caddoan languages. These languages once had a broad geographic distribution, but many are now extinct. The modern languages in the Caddoan family include Caddo and Pawnee. Hernando de Soto
