This was a massive and fascinating historical experiment in governing a multiethnic state. Terry Martin provides a comprehensive survey and interpretation, based on newly available archival sources, of the Soviet management of the nationalities question. He traces the conflicts and tensions created by the geographic definition of national territories, the establishment of dozens of official national languages, and the world's first mass "affirmative action" programs.

Martin examines the contradictions inherent in the Soviet nationality policy, which sought simultaneously to foster the growth of national consciousness among its minority populations while dictating the exact content of their cultures; to sponsor national liberation movements in neighboring countries, while eliminating all foreign influence on the Soviet Union's many diaspora nationalities. Martin explores the political logic of Stalin's policies as he responded to a perceived threat to Soviet unity in the 1930s by re-establishing the Russians as the state's leading nationality and deporting numerous "enemy nations".
