Abstract: This article provides a critical analysis of the mechanisms and consequences of Russian colonial policy in the last decades of the imperial era, with a particular focus on the land reforms initiated after Stolypin’s agrarian transformation of 1906 and their impact on the demographic landscape of the colonized territories, especially in Central Asia. The study shows how these measures, officially aimed at regulating internal peasant unrest and increasing agricultural productivity, actually served as an instrument of imperialist expansion, demographic engineering and social control. Through a detailed study of archival materials, statistical data and the work of scholars, the author demonstrates how the Russian authorities facilitated the resettlement of Slavic settlers in non-Russian peripheries – primarily in Turkestan – with the aim of strengthening political power, exploiting agricultural resources and changing the ethnic composition of the region. The analysis also covers the socio-political consequences of such demographic interventions: the dispossession of indigenous peoples of their land rights, the aggravation of inter-ethnic relations, environmental degradation due to intensive farming and the administrative marginalization of indigenous peoples.
