Cultural Evolution at Cahokia Julie Zimmermann Holt Cahokia, some 20 minutes from SIUE, is the largest archaeological site north of Mexico, named by UNESCO a World Heritage site. While most archaeologists agree that Cahokia was a city –one of the largest cities in the world between AD 1100 and 1200 – they argue about how powerful or organized that city really was. Archaeologists traditionally portrayed Cahokia as the powerful center of a complex society, and some went so far as to suggest that it was the center of a state. This image of a “mighty Cahokia” fell out of favor several decades ago. Most archaeologists since then have described Cahokia as the center of a chiefdom, although they might debate how powerful that chiefdom was. Most would admit that all other chiefdoms known east of the Mississippi were a fraction of the size which probably reflects the level of organization of those societies. However, a minority view persists that Cahokia was “more” than a chiefdom. Most vocally, Timothy Pauketat has recently referred to Cahokia as a “civilization.” More recently I have argued that Clifford Geertz’s model of the theater state offers a non-western alternative way of thinking about Cahokia and the nature of its power. These debates reflect shifting attitudes within the broader field of anthropology towards cultural evolution, history, and human agency as explanations of culture change. This presentation will examine debates about cultural evolution at Cahokia as a reflection of broader paradigm shifts within anthropology and anthropological archaeology.
