The present volume is the last in the Entangled Balkans series and marks the end of several years of research guided by the transnational, “entangled history” and histoire croisée approaches. The essays in this volume address theoretical and methodological issues of Balkan or Southeast European regional studies—not only questions of scholarly concepts, definitions, and approaches but also the extra-scholarly, ideological, political, and geopolitical motivations that underpin them. These issues are treated more systematically and by a presentation of their historical evolution in various national traditions and schools. Some of the essays deal with the articulation of certain forms of “Balkan heritage” in relation to the geographical spread and especially the cultural definition of the “Balkan area.” Concepts and definitions of the Balkans are thus complemented by (self-)representations that reflect on their cultural foundations.
