Xiongnu
The Xiongnu () were a confederation of nomadic peoples who, according to ancient Chinese sources, inhabited the eastern Asian Steppe from the 3rd century BC to the late 1st century AD. Chinese sources report that Modu Chanyu, the supreme leader after 209 BC, founded the Xiongnu Empire.

Since the early 19th century, a number of Western scholars have proposed a connection between various language families or subfamilies and the language or languages of the Xiongnu. Albert Terrien de Lacouperie considered them to be multi-component groups. Many scholars believe the Xiongnu confederation was a mixture of different ethno-linguistic groups, and that their main language (as represented in the Chinese sources) and its relationships have not yet been satisfactorily determined. Kim rejects "old racial theories or even ethnic affiliations" in favour of the "historical reality of these extensive, multiethnic, polyglot steppe empires".
