This module explores the role of the EU as an international actor in the sphere of foreign policy, international relations, and security and defence. It analyses the historical development of EU foreign policy and its various dimensions, the main institutions and players involved, but also the different roles the EU assumes when acting internationally, and how it relates to regional and global partners. The module delves into some critical questions about the nature of the EU- whether it actually is an actor capable of making a distinct foreign policy- and whether any policy-making at EU level, particularly in matters of security and defence, is legitimate. This module can build on previous knowledge about EU history and integration or can provide new and specialised knowledge about this organisation’s foreign policy.
