context: The Kazakhization of Soviet Kazakhstan is a series of events held by the Soviet authorities on the territory of modern Kazakhstan (in the Kyrgyz Autonomous Soviet Socialist Republic, Kazak Autonomous Soviet Socialist Republic, Kazakh Autonomous Soviet Socialist Republic, Kazakh SSR) in the national question. Kazakhization was expressed in preparing and promoting Kazakh leadership positions, introducing the Kazakh language in paperwork, education, encouraging the publication of mass media and literature in the Kazakh language, creating an education system in the Kazakh language, as well as deporting non-Kazakh people (especially Slavic) and weaning their lands in favor of the Kazakhs. In the framework of Kazakhization, the training of workers of industrial enterprises created in Kazakhstan was carried out. In the 1920s and early 1930s, intensified and the longest-running Kazakhization took place as part of the all-Union policy of indigenousization. In the second half of the 1940s - the mid-1980s, Kazakhization was mainly “personnel” - in the form of nominating ethnic Kazakhs to leading posts in the Kazakh SSR, filling them with places in universities. At the same time, attempts to translate paperwork and education into the Kazakh language during this period have not been made.
