The concept of civilization has long been the basis for theories about how societies evolve. This provocative book challenges that concept. The author argues that a "civilization bias" shapes academic explanations of urbanization, colonization, state formation, and cultural horizons. Earlier theorists have criticized the concept, but according to Jennings the critics remain beholden to it as a way of making sense of a dizzying landscape of cultural variation. Relying on the idea of civilization, he suggests, holds back understanding of the development of complex societies. uses case studies from across the modern and ancient world to develop a new model of incipient urbanism and its consequences, using excavation and survey data from Çatalhöyük, Cahokia, Harappa, Jenne-jeno, Tiahuanaco, and Monte Albán to create a more accurate picture of the turbulent social, political, and economic conditions in and around the earliest cities. The book will influence not just anthropology but all of the social sciences.
