Summary

International relations scholars of all stripes have long been interested in the idea of “international order.” At the most general level, international order entails some level of regularity, predictability, and stability in the ways that actors interact with one another. At a level of higher specificity, however, international orders can vary along a number of dimensions (or fault lines). This includes whether order is thin or thick, premised on position or principles, regional or global in scope, and issue specific or multi-issue in nature.

When it comes to how orders emerge, the majority of existing explanations can be categorized according to two criteria and corresponding set of questions. First, are orders produced by a single actor or a select subset of actors that are privileged and powerful, or are they created by many actors that are roughly equal and undifferentiated in capabilities and status? Second, do orders come about from the purposive behavior of particular actors, or are they the aggregated result of many behaviors and interactions that produce an outcome that no single actor anticipated? The resulting typology yields four ideal types of order explanations: hegemonic (order is intentional, and power is concentrated), centralized (order is spontaneous, but power is concentrated), negotiated (order is intentional, but power is dispersed), and decentralized (order is spontaneous, and power is dispersed).

Finally, it is useful to think about the process by which order can transform or break down as a phenomenon that is at least sometimes distinct from how orders emerge in the first place. The main criterion in this respect is the rapidity with which orders transform or break down. More specifically, they can change or fall apart quickly through revolutionary processes or more gradually through evolutionary ones.
