Conventional historical and popular accounts tend to emphasize sharp polarities between empires and nation-states. While an empire is traditionally associated with conquests, slavery, political inequalities, economic exploitation and the wars of yesteryear, a nation-state is understood to be the only legitimate and viable form of large-scale territorial organization today. This article challenges such interpretations by focusing on the organizational and ideological continuities between the imperial and the nation-state models of social order. In particular, I focus on the role coercive and (...) ideological apparatuses as well as the transformation of micro-solidarities play in the formation of polities over long periods of time. I argue that although empires and nation-states are different ideal types of polity they are highly compatible and as such prone to metamorphosing into each other. More specifically I explore how, when and why specific coercive-organizational, ideological and micro-interactional processes make this periodic historical metamorphosis possible. (shrink)
