The Qaŋlï (Qangli) Turks were a numerous people, active in Eurasia in the twelfth to thirteenth centuries, but their ultimate origins remain a matter of debate. Often considered by modern scholars to be a part of the Kipchaks (Cumans), others have different opinions. One of these links them to cart-riding early medieval Turkic tribes called Tägräks, known in Chinese sources as Tiele 鐵勒, among other forms. This article examines the earliest possible (eighth-century) references to the Qaŋlïs in the historical sources, and points to the potential links between them and various tribes seen among Turko-Mongol groupings of the ninth to tenth centuries mentioned in the Chinese sources, such as the Black Carts (Heichezi 黑車子). Another aspect that this article focuses on is how both historical and mythological texts of the Mongol period show the Qaŋlïs to be a people distinct from the Kipchaks. Ultimately, this study, which is based on both historical sources and modern research, proposes to locate the origins of the Qaŋlï Turks among Tägräk tribes.
