Situated within the wider post-secular turn in politics and international relations, this volume focuses not on religion per se, but rather explicitly on theology. Contributions to this collection highlight the political theological foundations of international theory and world politics, recasting theology and politics as symbiotic discourses with all the risks, promises and open questions this relation may involve. The overarching claim the book makes is that all politics has theology embedded in it, both in the genealogical sense of carrying ineradicable traces of rival theological traditions, and also in the more ontological sense of being enacted by alternative configurations of the theologico-political. The book is unique in bringing together a diverse group of scholars, spanning knowledge areas as varied as IR, political theory, philosophy, theology, and history to investigate the complex interconnections between theology and world politics. It will be of interest to students and scholars of political theory, international relations, intellectual history, and political theology.
