Religion and Diplomacy: The ‘Clash of Civilizations’ as Historical Libel

The ‘Clash of Civilizations’ hypothesis suggested that global politics would revert to inter-civilizational (inter-religious) conflict with the end of the Cold War. Conceptual and empirical refutations followed, but the idea that pre-Cold War inter-polity interaction was generally characterized by such conflict was not addressed. We consider this a possible historical libel. First, we briefly review the position of major faith traditions toward making and keeping agreements with those of other faith traditions. Most forms of agreements are sanctioned, and there is inconsistent and minimal support for duplicity. Second, using the MATRS database of multilateral treaties, we identify 79 sovereign entities active between 1750 and 1900 (when multilateral treaties were numerous and official state religions were prominent), link states to their official religions, and analyze the pattern of 385 multilateral treaties’ signings. We conclude that there is no tendency among states with one official religion to avoid entering into treaties with those of other official religions. The ‘Clash of Civilizations’ hypothesis is a historical myth.
