Recently published histories of national groups living under Soviet rule provide a rich secondary literature on the various paths taken by these groups to be incorporated into the Russian empire and the Soviet state. Social scientists who want a differentiated understanding of political mobilization among the various nationalities should not ignore these important contributions. This review essay attempts to synthesize these histories in order to provide a coherent model of nationality politics. Proposing an “elite incorporation model” of political mobilization, the essay accounts for different sources of national protest. The model weight not only the pressures for national autonomy and republican sovereignty but also the pressures that provide support for the Union.
