In the Balkans, apart from NATO and the UN, the European Union has become the subject of security and building, maintaining and enforcing peace. The EU’s goals are taken through two instruments: military and civilian crisis management missions under the Common Security and Defense Policy (CSDP) and enlargement policy. The issue of this article is centered around EUFOR Althea’s operation in Bosnia and Herzegovina, which undoubtedly belongs to the peacebuilding catalogue. The authors analyzed the conditions of the operation, the legal basis, the objectives, the tasks, the funding and the composition of the mission. It was also important to indicate successes and failures, and to outline the prospects for the crisis management mission development.
