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.

In the UNESCO-published "History of Civilizations of Central Asia", its editor János Harmatta concludes that the royal tribes and kings of the Xiongnu bore Iranian names, that all Xiongnu words noted by the Chinese can be explained from a Scythian language, and that it is therefore clear that the majority of Hsiung-nu tribes spoke an Eastern Iranian language.
