The end of communism brought hopes for a wholesale liberal-democratic transformation to the republics of the former Soviet Union. However, bitter disenchantment soon followed, as resurrected nationalism undermined the republics' stability and threatened democracy. Mass nationalist movements in these countries were not observed until the regime's initial liberalization. In most cases, the high phase of nationalist mobilization was reached only after the postcommunist state elites endorsed nationalism as an official policy of the state. In each instance, nationalist strategies of the state were defined in a complex interplay of domestic and international factors. Ethnicity became politicized as a resource for political action when other resources proved inadequate or insufficient. In addition, exogenous factors often played a leading role in this development.
