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.
Ordos culture
In Chinese accounts, the Xiongnu first appear at Ordos in the "Yi Zhou Shu" and "Classic of Mountains and Seas" during the Warring States period before it was occupied by the states of Qin and Zhao. It is generally thought to be their homeland; however, when exactly they came to occupy the region is unclear and archaeological finds suggest it might have been much earlier than traditionally thought.
