"After the Cold War, European militaries transformed officer education. Several consolidated military education institutions into a new arrangement of National Defence Universities with civilian academic accreditation. The proposed study will analyze their evolution and meanings using the “Officership as a Profession” school. The study sees officership to be a profession, and officers as professionals. The military profession is unique in its reliance on knowledge and skills related to the “management of violence”. Professional military educational institutions equip officers with expert knowledge and values unique to the profession. These institutions are especially important when militaries facing dramatic changes. Such an upheaval resulted from the Common Security and Defence Policy (CSDP). One of its results is a growing demand for improved interoperability between European armed forces which turned to military colleges for achieving a better level of interoperability.The research aims to consider the derivation of these reforms; To consider the impact(s) of civilianization and Europeanization on long-standing proud institutions; To disaggregate their impacts on military education institutions; To investigate their future implications on the nature of the European military profession and civilian-military relations; To contextualize these reforms within an EU context; and assessing prospects for further intra-European cooperation in military education."
