Turhan, EbruReiners, Wulf2025-02-202025-02-202021978-303070890-0978-303070889-4https://doi.org/10.1007/978-3-030-70890-0_1https://hdl.handle.net/20.500.12846/1712This chapter presents the rationale, objectives, and structure of this volume and introduces the reader to the new complexities that epitomize EU-Turkey relations. To this end, it provides a set of guiding questions for the volume, offers a systematic overview of the major milestones in the EU-Turkey relationship, and classifies the key determinants of these developments under three categories: multilateral frameworks and external crises, internal EU and Turkish domestic developments, and EU-Turkey bilateral processes. The chapter then introduces the three-dimensional approach of the volume that brings together the analytical lenses of (1) theories and concepts, (2) institutions, and (3) policies based on a comprehensive survey of both key primary sources and academic literature dealing with the relationship. In a final step, the chapter presents the ensuing fifteen contributions to the volume. © The Author(s) 2021.eninfo:eu-repo/semantics/openAccessUnpacking the new complexities of EU-Turkey relations: Merging theories, institutions, and policiesBook Part10.1007/978-3-030-70890-0_11352-s2.0-85150480866
