north to the protection of Cossack forts. The invasion of Khalkha by Galdan Boshogtu Khan in 1688 stopped Khalkha resistance to the Cossack advance and sent more Mongol refugees fleeing into Russian control. Finally, the Selenge Mongols, cut off by the new border from their Khalkha kinsmen and mixed with displaced Buriats and Khori, gradually accepted the Russian designation as Buriat. These groups are: Descendants of Okhin Taij (grandson of Khalkha's Tsogtu Khan); Khatagin; Atagan; Ashabagad; Sartuul; Tavnanguud; Yungsiebu; O'zeed; Uuld; Tsongool. The Tsongool subclans are as follows: 1. Uriankhad, 2. Bolingud, 3. Baatud, 4. Ashibagad, 5. Avgachuud, 6. Sharnuud, 7. Nomkhod, 8. Khamnigan, 9. Arshaantan, 10. Khorchid, 11. Naimantan, 12. Yunshööbü, 13. Khotgoid, 14. Eljiged, 15. Örlüüd, 16. Tavnanguud, 17. Orongoi, 18. Tsookhor, 19. Sartuul, 20. Sharaid, 21. Temdegten. Mongolian academician, writer, and scholar Byambyn Renchin () is a representative of this ethnic group. His father belonged to the Yungshiebu tribe and his mother was a direct descendant of Genghis Khan through Khalkha's Tsogtu Khan.
