This project explored the overlooked role of state socialist intellectuals, experts and governments from Eastern Europe, Africa, and Asia in developing international law in the twentieth and twenty-first centuries. It highlighted both contributions to current international law, and competing ideas and initiatives which, although they did not achieve global consensus, constituted important disruptive moments in the history of international law. By examining how different state socialist ideologies, legal principles and realpolitik affected contemporary frameworks, we contested existing linear and Western-dominated histories. We considered these state socialist engagements in interaction with liberal and Western approaches and underlined the divisions that existed between socialisms from different world regions and across the North-South divide. The project also explored the legacies of these attempts at a socialist international law and the way they are still impacting the present. More details are available in the extensive activity report.
