This talk examines Soviet nationalities policy in Central Asia through the lens of a prosopographical overview of ethnic Kazakhs within the Kazakhstan’s pre-war nomenklatura, using biographical data to provide a statistical picture of Kazakhstan’s Party elite. Analyzing those Kazakhs who served as members of the republic’s Party Bureau between 1920 and 1937—examining when and where they were born, where they went to school, and when and how they joined the Party—offers insight into the broader process of elite formation in the early Soviet period, revealing clear patterns in terms of who became a Bolshevik and what types of people achieved political success in the first two decades of Soviet rule. It also illustrates the enduring resonance of the Russian colonial presence in Kazakhstan in determining the course of revolutionary change in the republic, and indeed its political landscape across the following decades.
