Abstract. The article investigates nation-building trajectories and civic identity formation in Eastern Europe. The indicated processes in Eastern European states are notably different from those in the Western part of Europe. They are hindered by the specific historical development of these countries and by a set of local characteristics in particular. Quite often, there are such obstacles as unresolved ethnic conflicts and non-involvement of minorities in the building of common political and public practices within the state. The paper aims at assessing the current situation, evaluating international and interethnic regulation practices in the region and their efficiency, working out criteria of a civic nation formation in Eastern European countries. This is, first of all, a question of sociocultural and political consolidation. Social activism and civic participation are also significant factors. Finally, the very nature of nationalism and the use of the “alien image” in relation to other ethnic groups within the state are important. On this basis, the article proposes a typology of the countries according to the stage of a civic identity formation, and assesses possible future developments.
