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
In 48 CE, after a dynastic conflict within the Xiongnu confederacy, an unnamed Shanyu (Shanyu or Chanyu meaning 'Son of Eternal Sky' and equating with the title of King) (48–56 CE) brought eight tribes of the Western Wing to China under a renewed heqin treaty, creating a polity of Southern Xiongnu in vassalage to China and a polity of Northern Xiongnu who maintained their independence.
