Historiography and transformation of ethnic identity in the Mongol Empire: the Öng’üt case

Throughout their history, Inner Asian empires used familiar imperial institutions to rapidly impose new ethnic designations and their attendant languages, such as ‘Türk’ or ‘Mongol’, on their subjects. The swiftness of this integration into new ethnic designations should not be taken to mean that this integration was painless, however. In the well-documented Mongol empire, for example, this incorporation was extremely traumatic for many Inner Asian ethnic groups, even where the subordinate local elites achieved high status in the new regime. This may be seen in the case of the Öng’üt, a Christian Turkic-speaking people of Inner Mongolia whose rulers then became key marriage partners of the Mongol aristocracy. Successive iterations of the origin story of the Öng’üt rulers show how these histories went through vast changes as they were forcibly incorporated into the new empire, and dealt with the internal conflicts sparked by that incorporation. Previously central parts of their historic past, such as Christianity and service as border guards to the previous Jin dynasty, had to be marginalized and a new historical past had to be created. Historiography thus reflected and shaped changes in ethnic identity in a traumatic dynastic transition.
