Research on the forced migration of Lithuanians to the east of the former Soviet Union in the 1940s and early 1950s throws up a wide range of issues. Methodologically, most of such studies are similar in terms of the sample chosen, which consists of the former prisoners of gulags and exiles who have returned to Lithuania, but it usually disregards those who stayed. Accordingly, the Lithuanian diasporas that emerged in the east after the forced migration, including in Kazakhstan, have not (...) been studied in detail. In this article, our aim is to answer the questions of how and in what private and public contexts processes of the ethnic identification of the Lithuanian diaspora in Kazakhstan are determined, how ethnic boundaries are drawn, and what cultural and social resources are used for this purpose. As the research revealed, the conceptualisation of ethnicity implied by the Kazakhstan state that has been adopted by our informants eliminates its cultural content, or at most reduces it to forms evident in festive culture, as well as the need and possibilities for its expression. As a result, ethnic identity is constructed on the basis of what is almost the sole criterion: Lithuanian descent in the form of ‘root’ or ‘blood’. For most of our informants, ‘roots’ are just a fact of origin, as shown in the practice of entering Lithuanian ethnicity in personal documents, an officially required practice which does not have and does not presuppose any enactment of ethno-cultural differences. Ethnicity, which is seen as ‘in-rooted’ but also as culture-less and as muted by a doubling of roots among ethnically mixed families of origin, enables a whole spectrum of manipulations of ethnic identity. One such manipulation is attempting to profit from the Lithuanian ethnic identity by turning it into a resource for acquiring benefits. The practice of profiteering from the Lithuanian ethnic identity, and thus its transformation into a resource for gaining benefits in the forms of Lithuanian citizenship and a hope of being repatriated to Lithuania, is probably the most frequent factor in becoming Lithuanian by remembering Lithuanian roots and activating the Lithuanian ethnic identity.
