“…Although studies of chiefdoms have retained a strong focus on the development of complexity, much of the research has centered around defining regularities in the enabling conditions through which strategizing elites can gain and maintain power (Earle, 1991a). The retreat from explanatory models is closely connected with a critical reexamination of the traditional evolutionary typology of bands, tribes, chiefdoms, and states as appropriate units of study (Abrams, 1988;Gailey and Patterson, 1987;Kristiansen, 1991;Yoffee, 1993). The avoidance of explanation also stems from the more general critique of the "classic" processual model's emphases on systems theory, cultural ecology, and cultural evolutionary/adaptationist perspectives as ahistorical, unilineal, functionalist, and environmentally deterministic constructs (Hodder, 1986;Preucel, 1991;Shanks and Tilley, 1987;Trigger, 1991).…”
