Abstract

EU cooperation in foreign, security, and defence policy has developed rapidly since the launch of the Common Foreign and Security Policy (CFSP) in the early 1990s. The first section of this chapter charts the first steps towards a common policy in this area, including the development of the Common Security and Defence Policy (CSDP) and the gradual militarization of the EU. The chapter then reviews the key theoretical debates on the EU’s role as a foreign and security actor. The subsequent section analyses the main actors involved in the CFSP, focusing in particular on the role of the member states and EU institutions in the development of the policy. The next section of the chapter evaluates the range of military and civilian CSDP operations and missions that the EU has undertaken to date, before examining the key challenges that the EU faces in this area.
