Contributor(s): Professor Denisa Kostovicova | In her inaugural lecture, Denisa Kostovicova discusses how former opponents engage with the legacy of mass atrocity. War crimes need to be addressed, if peace is to be built. But, in divided societies polarised by violence, war crimes talk can deepen the divisions. Kostovicova draws on her study of post-conflict Balkans and presents lessons for contemporary conflicts. She locates the possibilities for peace in political communication across conflict lines, assesses the risks and considers alternatives, such as arts-based approaches.
