Abstract This article explores the making of the State of Syria after the dissolution of the Ottoman Empire. I argue that an event-based approach in global legal history offers a useful perspective for studying the transition from imperial to international and national systems. Drawing on new archival research in France and Saudi Arabia, I focus upon the creation of the 1928 Syrian constitution in the League’s mandate to show the administrative framework of political orders. First, I describe the French administrative logic through the story of the international ‘organic law’. Second, I describe the way the organic law necessitated the Syrian political constitution. The constrained constitutional process resulted in a clash and a compromise about a Muslim president between secularist republicans and exiled, Saudi-related Muslim monarchists. Global history can profit from this approach by rethinking decolonization as administrative reorganization and by focusing on dissenting, non-state actors in state-making.
