This article examines the transformation of the social role and status of biys in Kazakh society under the influence of Russian colonial policies in the 19th century. Traditionally, biys were highly respected figures within the kara suyek (black bone) social stratum, valued for their deep understanding of customary law (adat), wisdom, and the respect they commanded within their communities. Unlike the hereditary power structures of the Chingissids, biys derived their authority from personal merit and communal trust, embodying a form of leadership distinct from the lineage-based rule of the Kazakh aristocracy. Russian colonial policies, including the 1822 Statute on the Siberian Kirghiz and reforms of 1867-1868, aimed to integrate biys into a hierarchical colonial system, thus curtailing their authority and diminishing their traditional social rank. This study examines how these colonial interventions altered the status of biys, repositioning them from autonomous leaders to regulated officials within the Russian legal framework. Despite these changes, biys retained cultural influence, continuing to serve as informal leaders and custodians of Kazakh identity, thus embodying resilience in the face of colonial control. This research contributes to a nuanced understanding of how indigenous leadership roles were redefined under imperial rule while preserving significant elements of their traditional cultural standing.
