Energy, migration and politics are three central themes of contemporary international relations that can no longer be considered in isolation from one another. This book approaches them not as disconnected phenomena but within their mutual interdependencies, through the holistic lens of an international relations perspective. The volume brings together five original chapters, ranging from security and great-power rivalry in the Baltic region and the European Union’s search for strategic autonomy after the war in Ukraine, to the limits of Europe’s normative power in the face of minority rights, the migration-management practices of contested political entities, and finally a rethinking of geopolitics under the conditions of the risk society. By uniting different theoretical approaches and geographical contexts under a single framework, the book offers readers a multi-layered field of discussion that is not confined to a single case or method. This diversity—spanning security studies, European integration, minority rights and risk theory—allows the energy-migration-politics triangle to be viewed through multiple windows. The book serves as a comprehensive reference for students, researchers and readers interested in the field.
