Xianbei state

The Xianbei state or Xianbei confederation was a nomadic empire which existed in modern-day Mongolia, Inner Mongolia, northern Xinjiang, Northeast China, Gansu, Buryatia, Zabaykalsky Krai, Irkutsk Oblast, Tuva, Altai Republic and eastern Kazakhstan from c. 93 to 234. Like most ancient peoples known through Chinese historiography, the ethnic makeup of the Xianbei is unclear, though they are believed to have been a Proto-Mongolic people. There are also other strong suggestions that they were a multi-ethnic confederation with Mongolic and Turkic influences. They originated from the Donghu people who splintered into the Wuhuan and Xianbei when they were defeated by the Xiongnu at the end of the third century BC. The Xianbei were largely subordinate to larger nomadic powers and the Han dynasty until they gained prominence in 87 AD by killing the Xiongnu chanyu Youliu. However unlike the Xiongnu, the Xianbei political structure lacked the organization to pose a concerted challenge to the Chinese for most of their time as a nomadic people.
