Despite the development of Euro-Turkish relations, the in-depth examination of the position of Turkey in the European area has laid the foundations for intense basic research emphasizing the complexity, longue durée, and reciprocity of the transfer processes. Accordingly, irrespective of the political situation, it is not a question of whether Turkey is or should be part of Europe, or whether it is or should be linked to Europe. Of greater concern is the fact that Turkey has multi-faceted relations with the countries to the west and north of it, which must be properly analyzed and recognized. At the same time, this basic research on the Turkish-European relationship is polycentric and relies on different networks depending on the discipline and scholarly language. The task of the research field European-Turkish relations from a mutual and long-term perspective was to achieve a deeper understanding of these relations by bringing the different subfields together.
