Legal experts of Central Eastern Europe remain largely unknown figures of international law making after 1945. Acting as representatives of dictatorial regimes and often contributing to the legalization of political violence, their works and visions have been dismissed as irrelevant for the development of international law and justice. Yet, many of them were key players in proposing innovative legal ideas and concepts, which have decisively shaped contemporary international law. This project critically engages with the biographies and works of several legal experts from socialist countries, and their engagements within the UN-system and transnational cooperation with their Global South and Western counterparts. Both for scholars and a wider audience, we present here several biographies of legal experts from Central and Eastern European countries.
