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.
Five Barbarians
As the Northern Xiongnu declined under internal and external conflicts, the Southern Xiongnu received waves of new migrants, and by the end of the first century CE a majority of the Xiongnu resided in China proper and along its northern borders.
