Jean Monnet Module “Security Issues of European Integration” (600161-EPP-1-2018-1-RU-EPPJMO-MODULE) reveals the features of the formation of a European security system in the context of the development of an integration project. The methodological basis for the study of the material and its structuring are individual developments of the Copenhagen School of Security. Students get acquainted with the theory of integration, security theory, the history of the formation of the European security system in the second half of the twentieth century, European and national security agendas in the 1990-2000s. Such accents make it possible to reveal the problems and contradictions of the integration process, the peculiarities of the foreign and domestic policies of the European Union member states, and assess the EU’s contribution to international security.
