This chapter examines the European Union’s (EU’s) Common Foreign and Security Policy (CFSP). It tells the story of increasing co-operation between member states on foreign policy matters, first with European Political Co-operation (EPC) and, since the 1990s, with CFSP and a Common Security and Defence Policy (CSDP). The chapter highlights the internal dynamics and external events that drove the member states towards such co-operation and considers the most recent example of such efforts: the 2017 attempt to create a system of permanent structured co-operation (PESCO). However, it is noted that the EU remains far from having a truly supranational foreign policy and there remains a reluctance from member states to push much further integration, given states’ keen desire to remain sovereign in this area. Finally, the chapter considers the EU’s status as a ‘power’ in international relations, noting that it has diminished in important respects since 2003, but remains an important economic power.
