More than three decades since the fall of the Soviet Union, several conflicts over territory and political influence in Eastern Europe persist. This volume gathers new empirical and conceptual perspectives on the situation regarding security and human rights in the EU's eastern neighborhood. The first part of this volume consists of five articles, detailing the origins and recent developments in the conflict areas of Donbas (Ukraine), Transnistria (Moldova), Abkhazia and South Ossetia (Georgia), and Nagorno-Karabakh (Armenia and Azerbaijan). The second part provides a comparative perspective, focusing on the implications of protracted conflicts for European security, the OSCE, and international law. The articles analyze the regional context, explain the role of regional powers such as Russia, Turkey, and the EU, and provide clear policy recommendations regarding conflict resolution and accountability.
