"Nations, like nature, are said to abhor a vacuum." Arnold Wolfers' words cunningly summarize a wisdom commonly held both within the academy and policy communities: just like black holes in space, power vacuums in international politics are viewed as exerting tremendous gravitational force, pulling in states and as a result increasing security competition and the likelihood of interstate war. Yet despite the frequency with which power vacuums and their pernicious consequences are referred to in scholarly and public discourse, social scientists – and in particular students of international relations – have so far failed to specify what power vacuums are, let alone discuss their implications for international politics. This project seeks to rectify these omissions by answering a series of foundational questions: what are power vacuums? Why do states compete for control over some but not others? And what accounts for variation in the types of strategies they employ when they decide to compete?
