Introduction. The article analyzes legends and songs about Genghis Khan recorded in expeditions across Buryatia, Mongolia and China — to further compare them with related archival and published materials. Goals. The work aims at identifying distinctive features inherent to folklore texts dealing with Genghis Khan in different linguistic and ethnic environments. The issue of revival of ethnic consciousness actualizes insights into ethnic culture and its peculiarities. Methods. The paper is first to consider local versions of Buryat songs about Genghis Khan in a comparative aspect. Semantic contextual analysis proves instrumental in revealing ethnic markers. Results. The article discusses songs about Genghis Khan of both local and general Mongol significance. Songs about kinship with Genghis Khan and the ancestral homeland of Buryats — Nayan Nava — have a local and specifically tribal meaning being connected to the history of the Khori Buryats proper. Songs with a motif of chase contain parallels with plots of all-Mongol toponymic legends. The song titled ‘Two Steeds of Bogdo’ (Bur. Bogdyn hoyor zagal) and known among the Mongolic peoples dates back to the Mongolian medieval literature — The Tale of Two Steeds of Genghis Khan. The songs are examined in comparison with legends and The Secret History of the Mongols. Conclusion. Contextual analysis of songs about Genghis Khan along with legends and The Secret History reveals a hidden deep layer in the semantics of texts. The songs of Russia and Mongolia’s Buryats identify ancient roots of the motif of kinship with Genghis Khan that date back to the historical homeland. The Shinehen Buryats of the Inner Mongolia Autonomous Region (China) have shown a perfect preservation of authentic materials in an isolated environment, while Mongolia’s Buryats experienced a transformation and song borrowings in the close ethnic culture. The paper also concludes there are virtually no such songs about Genghis Khan among modern Buryats of Russia. In general, the comparative analysis of Buryat songs about the legendary warlord proves those had been created in their historical homeland of present-day Russia to be further preserved both in the alien (China) and kindred (Mongolia) ethnocultural environments.
