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.
Luandi
The Luandi (; alternatively written as Xulianti ) was a clan and the ruling dynasty of the ancient Xiongnu that flourished between 3rd century BCE to 4th century CE. The form Luandi (挛鞮) comes from Hanshu, while the form Xulianti comes from Hou Hanshu. Anna Dybo reconstructed 攣鞮's Old Chinese pronunciation as "*r(h)wan-de" & posits that the clan's name was an Iranic loanword, cognate with Khotanese "runde", plural of "rre" from "*rwant-" "king". There were four other noble tribes: Huyan, Xubu, Qiulin and Lan. The Huyan belonged to the dominating left wing, and the Lan and the Xubu belonged to the right wing.
