Drawing on previously inaccessible archival materials, David L. Hoffmann shows how this massive migration to the cities--an influx unprecedented in world history--had major consequences for the nature of the Soviet system and the character of Russian society even today.Hoffmann focuses on events in Moscow between the launching of the industrialization drive in 1929 and the outbreak of war in 1941. He reconstructs the attempts of Party leaders to reshape the social identity and behavior of the millions of newly urbanized workers, who appeared to offer a broad base of support for the socialist regime. The former peasants, however, had brought with them their own forms of cultural expression, social organization, work habits, and attitudes toward authority. Hoffmann demonstrates that Moscow's new inhabitants established social identities and understandings of the world very different from those prescribed by Soviet authorities. Their refusal to conform to the authorities' model of a loyal proletariat thwarted Party efforts to construct a social and political order consistent with Bolshevik ideology. The conservative and coercive policies that Party leaders adopted in response, he argues, contributed to the Soviet Union's emergence as an authoritarian welfare state.
