Europe is one of the major economic, political, and cultural regions having the highest degree of institutional interdependencies in the world. With the dissolution of the Soviet Union and the Warsaw Pact, the re-unification of Germany, and major institutional changes brought about especially by the European Union and NATO, the continent has undergone fundamental changes over the past 25 years. The course aims at giving a survey of foreign and security policy developments in post-Cold War Europe. It is designed for undergraduate students having basic knowledge of international relations. No prerequisites required. Basic material (English) will be conveyed during the course in order to prepare for next day’s lecture. The course content is divided in three parts. Part 1 explains the fundamental foreign and security policy changes in Europe resulting from the break-up of the hitherto existing international order at the end of the 1980ies and the beginning of the 1990ies. Part 2 focusses on the subsequent ideas and tasks in creating new regional arrangements and a new security environment in order to re-integrate the continent. Part 3 elaborates on foreign and security policies in Europa over the past 25 years reflecting the contradictory as well as complementary mixture of supranational, inter-regional, and national values, interests, and policies represented by European actors.
