The Doctoral School of the Faculty of History, University of Bucharest, would like to invite PhD candidates in history, political science, international relations, economics or any other related fields, from all over the world, to an international conference about borders, barriers and frontiers as they have evolved and shaped human society throughout centuries. Transnational, regional and global perspectives are especially welcome. 2018 marks the 100th year celebration of the end of the First World War, President`s Wilson Fourteen Points and the Great Union of Romania. The Versailles Peace Treaties reshaped Eastern Europe, in the context of the dissolution of empires and the creation of new nation-states. In order to mark these events, an academic debate about the role of borders in history is necessary.
