Sovereignty, Territoriality, and Private International Law in Classical Muslim International Law

Abstract

Scholars in recent years have shown interest in challenging the historical origins of international law and its normative claims to universality. This Article challenges the prevailing conceptions of Islamic international law (al-siyar), first set out in English-language scholarship by Majid Khadduri, as primarily an ad-hoc response to the failed aspiration of a universal Muslim commonwealth. It shows that Islamic international law, in its classical phase (eighth–thirteenth centuries), as first formulated by Iraqi, and later, Central Asian, scholars (who together later came to be known as Ḥanafīs), understood all legal order as being rooted in sovereignty and territoriality, with shared religion a secondary concern. This theory of legal order arose out of an understanding of political order as emerging from a natural and universal condition of war that is incidental to the individual’s natural sovereignty. I trace the genealogy of this conception to the founding moment of the Muslim commonwealth and describe its manifestation in classical Ḥanafī solutions to a series of cases in “private international law.”
