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.

However, the eastern part of north China came under the control of a rebel Xiongnu-Han general of Jie ancestry named Shi Le. Liu Yao and Shi Le fought a long war until 329, when Liu Yao was captured in battle and executed. Chang'an fell to Shi Le soon after, and the Xiongnu dynasty was wiped out. North China was ruled by Shi Le's Later Zhao dynasty for the next 20 years.
