Regional cooperation, once largely the preserve of democracies, is now seen in many regions characterized by autocracy. Indeed, authoritarian leaders increasingly cooperate regionally, above all to augment the resilience of their regimes. While the output from this cooperation differs considerably from liberal-democratic regionalism, the experience of European integration nevertheless sheds light on an important underlying dynamic within this growing autocratic cooperation. Indeed, as with early and mid-stage European regional integration, authoritarian regionalism is driven by functional demands arising from the limited access nature of their regimes. However, countervailing ideational dynamics (such as the increasing salience of identity and legitimacy issues), which affect regional cooperation, are present in many cases. These counter-functional dynamics largely pre-date regionalist efforts but appear to be exacerbated by regional cooperation. This paper examines the interplay between functional demands and counter-functional dynamics in the context of ‘protective regionalisms’ in Eurasia, the Gulf, and West Africa. As global politics becomes more polarized, with regionalism seen as a source of strength for authoritarian states, the dynamics and underlying logics of such projects become increasingly important.
