This chapter synthesizes archaeological, textual, and ethnohistorical data from or pertaining to the Mesopotamian Iron Age to reconceptualize the nature of the territoriality of the Neo-Assyrian Empire. Instead of seeing the Neo-Assyrian Empire as a monolithic political unit, I show that it was an expansionist state that applied varying degrees of power over conquered landscapes. In describing what I call the “geographies” of Assyrian power, I utilize a modified version of D'Altroy's territorial-hegemonic continuum to model the broader implications of these geographies for a more nuanced understanding of the spatiality of empire.
