This introductory contribution frames the theoretical and methodological endeavour of the special issue. The underlying goal of the special issue is two-fold: On the one hand, it aims to shed light on the diversity of discourse theories and related toolkits for analysis. On the other hand, it aims at applying these approaches to the European Union’s (EU) discursive practices, with special attention to foreign policy discourses. All contributions revolve around a central focus: the manifold ways in which various EU institutional, national or societal actors employ different discursive strategies (such as justification, legitimation, and argumentation) related to foreign policy with bilateral partners; within multi-lateral milieus or vis-á-vis domestic audiences. In the last section, the contributions to this special issue are briefly summarised.
