The way of formation of statehood and ‘stateness’ is rather long and complicated for countries, that have not been recognized yet. Their additional difficulties for ‘stateness‘ are conditioned by challenges and consequences of conflict, stringent limitation of international relations, lack of experience and knowledge of how to build a sovereign state. The paper by Violetta Manukyan proposes an integral model of assessing ‘stateness’, the so-called ‘Peace Index’ to comprehensively capture the levels of ‘stateness’ of such states. The index is discussed based on the examples of four non-recognised states of Post-Soviet space: Nagorno-Karabakh, Abkhazia, South Ossetia and Transnistria.
