We argue that the theory of anarchism presents a productive framework for analyzing decentralized societies. Anarchism encompasses a broad array of interrelated principles for organizing societies without the centralization of authority. Moreover, its theory of history emphasizes an ongoing and active resistance to concentrations of power. We present an anarchist analysis of the development of social power, authority, and status within the Coast Salish region of the Northwest Coast. Coast Salish peoples exhibited complex displays of chiefly authority and class stratification but without centralized political organization. Ethnographically, their sociopolitical formation is unique in allowing a majority of "highclass" people and a minority of commoners and slaves, or what Wayne Suttles described as an "inverted-pear" society. We present the development of this sociopolitical structure through an analysis of cranial deformation from burial data and assess it in relation to periods of warfare. We determine that many aspects of Coast Salish culture include practices that resist concentrations of power. Our central point is that anarchism is useful for understanding decentralized (or anarchic) networks-those that allow for complex intergroup relations while staving off the establishment of centralized political authority.It is said that the history of peoples who have a history is the history of class struggle. It might also be said, with at least as much truthfulness, that the history of peoples without history is the history of their struggle against the State. (Pierre Clastres 1987:218) Archaeologists and anthropologists have had difficulty characterizing Northwest Coast cultures because these societies were socially complex but lacked centralized authorities. Many have presented Northwest Coast societies as examples of chiefdoms because of the presence of chiefs. While these leaders were often dressed in the trappings of high authority, they were not the chiefs of the classic anthropological chiefdom model, which posits figures with consolidated authority over large territories. Rather, the power of Northwest Coast chiefs was quite limited in spatial and social scale. Ames (1995) andBill Angelbeck is an independent archaeologist and anthropologist based in Seattle (
