We propose that relations among hierarchy, political centralization, monumentality, and territoriality are mediated through the actions of people organized in social networks. The ways in which conceptual and tangible assets are continually mobilized within these overlapping webs shape and challenge political formations operating on multiple spatial scales. This network approach to the study of political form and change is used to disentangle the complex relations among power and place that characterized political relations in two adjoining portions of northwest Honduras during the Middle Preclassic (1200-200 B.C.E.). Attention is particularly directed to the variable success enjoyed by would-be magnates as they sought to mobilize local assets in the form of arable land, perennial water sources, labor, and material styles to fashion hierarchically structured webs focused on specific monumental centers. The implications of this study for understanding ancient political geography are reviewed.[social networks, power contests, Mesoamerica, Middle Preclassic, monumental architecture] W e address here a central question raised by Van-Valkenburgh and Osborne in the volume's introductory chapter: "Under what circumstances does the exercise of power over others result in the creation of territorially bounded polities?" The premise underlying this discussion is that power in all its forms is achieved, defended, and challenged through the manipulation of conceptual and physical resources by people operating within social networks of varying memberships and spatial scales. Physically delimited political units, when they exist, are the contingent and variably stable outcomes of how these assets are used in exerting power over others and resisting such pretensions. As VanValkenburgh and Osborne (this volume) note, not all political contests end in the creation of clearly bounded polities. Distinguishing territorial from nonterritorial forms of power structures in the archaeological record can be challenging. We use the results of our investigations into Middle Preclassic (1200-200 B.C.E.) political contests in the adjoining Naco and Middle Chamelecon-Cacaulapa (MC-C) drainages of northwest Honduras to illustrate how the network approach advanced here might be used to describe ancient struggles for preeminence; why some of these competitions resulted in the creation of spatially delimited realms; and how those bounded entities might be recognized archaeologically. At the chapter's conclusion we consider the possible utility of a network approach for understanding relations among power, resources, monumental architecture, and territoriality.
