The purpose of this article is to present the operational capabilities of the OSCE in regulating armed conflicts and their application in the former Eastern bloc countries. In order to show the role of the OSCE in the regulation of armed conflicts, OSCE operational capabilities have been structured in a conceptual grid including: OSCE regulatory tools – in the form of missions, field offices and field coordinators; regulatory mechanisms and emergency mechanisms applied in the light of the peaceful pathways of OSCE involvement in the regulatory process. The common feature of operation at each phase is the broadly understood maintenance of stability or achieving stability. There are armed conflicts against which the OSCE has selectively used regulatory activity, omitting certain phases of the conflict, and those against which the application of regulatory tools has not led to lasting stabilisation. The results presented in the paper confirm the correctness of considering the above theories against the background of the conflict cycle concept. Institutional and legal analysis and comparative analysis were used in this paper.
