Coles Creek culture is a Late Woodland archaeological culture in the Lower Mississippi valley in the Southeastern Woodlands. It followed the Troyville culture. The period marks a significant change in the cultural history of the area. Population increased dramatically and there is strong evidence of a growing cultural and political complexity, especially by the end of the Coles Creek sequence. Although many of the classic traits of chiefdom societies are not yet manifested, by 1000 CE the formation of simple elite polities had begun. Coles Creek sites are found in Arkansas, Louisiana, and Mississippi. It is considered ancestral to the Plaquemine culture.
The Plaquemine culture was an archaeological culture centered on the Lower Mississippi River valley. It had a deep history in the area stretching back through the earlier Coles Creek and Troyville cultures to the Marksville culture. The Natchez and related Taensa peoples were their historic period descendants. The type site for the culture is the Medora site in Louisiana; while other examples include the Anna, Emerald, Holly Bluff, and Winterville sites in Mississippi.
