The horrors of the Great War and the desire for peace shaped scholarship in International Law and International Relations (IR) during the late 1910s—a stimulating time for both disciplines. Scholars observed and analysed political events as they unfolded but also took an active part, as governmental advisors or diplomatic officials, in devising the new international order. The Paris Peace Conference and the subsequent birth of the League of Nations as well as the Permanent Court of International Justice served as testing grounds for new legal and political concepts. The end of the First World War was in many ways a milestone for both disciplines, prompting scholars to reflect on the consequences of the war on society, politics, and the world economy. How could another world war be avoided in the future? How could states be held accountable for violations of international law? What were the preconditions for peaceful international governance? These questions led to pioneering research on issues such as arbitration, sanctions, revision of treaties, supra-national governance, disarmament, self-determination, migration, and the protection of minorities. At the same time, the study of International Law and IR also advanced in terms of methodology and teaching, including new professorships, journals, conferences and research centres.
A century later, it is a good moment to reflect upon disciplinary histories and revisit some of the theoretical and practical debates that shaped the period from 1914 to 1945. The workshop conveners are particularly (but not exclusively) interested in the following research questions:
