The international society approach to the study of international relations has advanced a distinct understanding of international order in world politics. Does this approach therefore also implicitly have a distinct understanding of disorder in world politics, too? From a close reading of this literature, and the writings of Hedley Bull in particular, I argue that a “purposive” understanding of disorder in world politics is evident, as well as a set of sociological explanations of it, including hierarchy conflict, political value conflict, and the structural contradictions of international society. I suggest that this approach is more insightful and promising for studying increasing manifestations of disorder in world politics than alternative realist approaches. Finally, I make the case that this concept's analytical utility and theoretical role in this approach is the assessment of the continued viability of international society as a path to order in world politics.
