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.

Proponents of a Turkic language theory include E.H. Parker, Jean-Pierre Abel-Rémusat, Julius Klaproth, Kurakichi Shiratori, Gustaf John Ramstedt, Annemarie von Gabain, and Omeljan Pritsak. Some sources say the ruling class was proto-Turkic, while others suggest it was proto-Hun. Craig Benjamin sees the Xiongnu as either proto-Turks or proto-Mongols who possibly spoke a language related to the Dingling.
