which Schuessler compares to Huns and Sanskrit Hūṇā. However, the same medial -ŋ- prompts Christopher P. Atwood (2015) to reconstruct *Xoŋai, which he derives from the Ongi River () in Mongolia and suggests that it was originally a dynastic name rather than an ethnic name. History Nomadic predecessors The territories associated with the Xiongnu in central/east Mongolia were previously inhabited by the Slab Grave Culture, which persisted until the 3rd century BC. Genetic research indicates that the Slab Grave people were the primary ancestors of the Xiongnu, and that the Xiongnu formed through substantial and complex admixture with West Eurasians. To the west, the Pazyryk culture (6th-3rd century BC) immediately preceded the formation of the Xiongnus. A Scythian culture, it was identified by excavated artifacts and mummified humans, such as the Siberian Ice Princess, found in the Siberian permafrost, in the Altay Mountains, Kazakhstan and nearby Mongolia. To the south, the Ordos culture had developed in the Ordos Loop (modern Inner Mongolia, China) during the Bronze and early Iron Age from the 6th to 2nd centuries BC, and is of unknown ethno-linguistic origin, and is thought to represent the easternmost extension of Indo-European-speakers. The Yuezhi were displaced by the Xiongnu expansion in the 2nd century BC, and had to migrate to Central and Southern Asia. Early history Western Han historian Sima Qian composed an early yet detailed exposition on the Xiongnu in one liezhuan (arrayed account) of his Records of the Grand Historian ( BC), wherein the Xiongnu were alleged to be descendants of a certain Chunwei, who in turn descended from the "lineage of Lord Xia", a.k.a. Yu the Great. Even so, Sima Qian also drew a distinct line between the settled Huaxia people (Han) to the pastoral nomads (Xiongnu), characterizing them as two polar groups in the sense of a civilization versus an uncivilized society: the Hua–Yi distinction. Sima Qian also mentioned Xiongnu's early appearance north of Wild Goose Gate and Dai commanderies before 265 BCE, just before the Zhao-Xiongnu War; however, sinologist Edwin Pulleyblank (1994) contends that pre-241-BCE references to the Xiongnu are anachronistic substitutions for the Hu people instead. Sometimes the Xiongnu were distinguished from other nomadic peoples; namely, the Hu people; yet on other occasions, Chinese sources often just classified the Xiongnu as a Hu people, which was a blanket term for nomadic people. Even Sima Qian is inconsistent in his Historical Records: occasionally, he
