Nomadic empire
The Xiongnu were a confederation of nomadic tribes from Central Asia with a ruling class of unknown origin and other subjugated tribes. They lived on the Mongolian Plateau between the 3rd century BC and the 460s AD, their territories including modern day Mongolia, southern Siberia, western Manchuria, and the modern Chinese provinces of Inner Mongolia, Gansu, and Xinjiang. The Xiongnu was the first unified empire of nomadic peoples. Relations between early Chinese dynasties and the Xiongnu were complicated and included military conflict, exchanges of tribute and trade, and marriage treaties. When Emperor Qin Shihuang drove them away from the south of the Yellow River, he built the famous Great Wall to prevent the Xiongnu from coming back.
Zhizhi Chanyu
Zhizhi Chanyu (, died 36 BC) was a Chanyu of the Xiongnu at the time of the first Xiongnu civil war, who held the north and west in contention with his younger brother Huhanye who held the south. His original name in Chinese transcription was Luanti Hutuwusi (), i.e. one of the Worthy Princes of the East (of the Luandi clan).
