The article deals with the spiritual and ideological components identified in the monuments of the Kanglу tribes, in the middle reaches of the Syr Darya River, characterized in the scientific literature as characteristic of the Hunno-Sarmatian tribes. As a Hun component, skeletons with an artificially deformed skull are implied, as a Sarmatian component - burials in the pose of a rider, when the legs are spread apart in a rhombus or in a pose with crossed legs. Theoretical data are presented to substantiate how these components ended up in the middle reaches of the Syr Darya.In particular, it is noted that this was caused by the migration of the Huns to the west and the migration processes that followed the collision of the Achaemenids and the Massagetae of the Aral coast. The study touches upon the spiritual and ideological component of the Sarmatians in the Kangly monuments. The study highlights the reasons for burial in a diamond-shaped or cross-legged position from the Kangl burial grounds. There are also arguments about the semantics of such burials and a reconstruction of the burial tradition of the ancient inhabitants. The discovered bone remains with deformed skulls from the Arys and Otrar regions' burials are considered a Hun component. Analogies are given from the monuments of Western Kazakhstan, the Aral Sea region, the Northern Black Sea region, and other regions. It has been established that a similar rite was also recorded in the monuments of Western Kazakhstan, Egypt, and the Mediterranean coast. Information about the causes of skull deformation is given.
