In this brief essay, I explore the relationship between ‘states’ (or more broadly, institutions of political authority) and ontological security. Drawing from historical examples, I argue that it is a mistake to assume that all ‘states’ seek ontological security: this generalisation applies only to those polities that claim to be the main ontological security providers. I then develop a typology of institutional ontological security provision arrangements as have existed throughout history, arguing that another reason the concept of ontological security is valuable for international relations (IR) is because it offers a way to compare systems across time and space without assuming the primacy of politics or religion. In summary, IR does not have to limit its use of the concept of ontological security to a synonym for ‘state identity’ – ontological security can offer much more than that by helping the discipline reach across time and space.
