Rather than within the UN system itself, the origins of Palestines international legal subalternity are located in British secret treaty-making and diplomacy between 1915 and 1947, particularly as institutionalized within the League of Nations system. Although the literature on the history of Palestine in this period tends to focus on political themes, this chapter examines this period through the cross-cutting theme of the Eurocentricity of international law and organization then prevailing. It is set against the backdrop of the global paradigm shift then occurring in the international system, from one based on the norms and values of the late-imperial age grounded in an international rule by law, to one based on those of an emerging liberal western rights-based discourse, ostensibly based on an international rule of law. The main systemic issue that emerges for Palestine at this time is its contingent and subaltern status in the international legal order, a status that was eventually placed before the UN in 1947.
