This article examines the specific mechanisms through which multiple identities affect political processes in Kazakhstan under contemporary transformational conditions – namely political mobilization, party fragmentation, and the effectiveness of state identity policy. Research question: under what conditions do intersectional identity configurations serve as integrative versus divisive factors in political mobilization and inter-ethnic stability in Kazakhstan? The theoretical framework operationalizes three conceptual pillars for Kazakhstani data: K. Crenshaw's intersectional approach, H. Tajfel and J. Turner's Social Identity Theory, and Q. Hirst's civic nationalism concept. Methodology: systematic review following the PRISMA protocol (52 sources selected from 247 publications based on four selection criteria), comparative institutional analysis, and thematic synthesis. Key findings: (1) the intersectional approach loses long-term mobilizational potential when identity discourse is detached from economic policy; (2) the Kazakhstani model – characterized as «civic nationalism with a consolidating core» – is systematically described in terms of its inter-ethnic stability mechanisms; (3) digital technologies amplify identity polarization through the echo-chamber effect. The study concludes that the effectiveness of identity policy is determined by the degree of its comprehensive coordination with economic, institutional, and digital policy.
