摘要:This article focuses on practices of citizenship in Estonia by persons with multiple citizenship or multicultural background. In the previous stages of research on this topic primary attention was paid to national citizenship, multiple citizenship and European Union citizenship as institutions, as well as the role of citizenship in the construction of European space. Expected "configurations" of multiple citizenship as articulated in Marshallian (1992) terms, as well as linkages between different spaces of membership (national and not-national) of citizenship as perceived by the national decision makers, mapped both avenues and bottleneck s for the future. Our research raises questions and problems related to citizenship as both an essential tool of nation building and of EU integration (cf. Ruutsoo and Kal ev 2006, Ruutsoo and Kalev forthcoming).
