One of the most pressing problems facing the Soviet government in the 1920s was how to recruit the technical intelligentsia and professional classes behind the new regime. Just as the officer corps of the Imperial government was a necessary adjunct to the Red Army during the Civil War, so the businessman, the doctor, and the bureaucrat were essential to the functioning of orderly social and political institutions under the New Economic Policy. The story of the economic concessions made to revive the dormant links between city and countryside is well known. But the recruitment of trained personnel involved not only economic concession but also ideological conversion. Beginning in 1921 the Soviet leaders took great pains to legitimize their rule by portraying themselves as heirs to Russian national traditions and defenders of Russian soil against foreign intervention.
