Xianbei

The Xianbei (/ʃjɛnˈbeɪ/; simplified Chinese: 鲜卑; traditional Chinese: 鮮卑; pinyin: Xiānbēi) were an ancient nomadic people that once resided in the eastern Eurasian steppes in what is today Mongolia, Inner Mongolia, and Northeastern China. The Xianbei were strongly suggested to be a multilingual, multi-ethnic confederation consisting of mainly Mongolic (who spoke either Pre-Proto-Mongolic,^[1] or Proto-Mongolic^[2][3][4] and Para-Mongolic^[4]), and, to a minor degree, Tungusic^[5] and Turkic peoples.^[1][6] 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. Following the split, the Xianbei people did not have a direct contact with the Han Dynasty, residing to the north of the Wuhuan. In the first century BC, the Xianbei began to actively engage in the struggle between the Han and Xiongnu, which culminated in the Xianbei replacing the Xiongnu on the Mongolian Plateau in 93 AD.

In the mid-2nd century, the chieftain, Tanshihuai unified the Xianbei and waged war against the Han dynasty. His confederation threatened the Han's northern borders for many years, but quickly disintegrated following his death in 181 AD. After suffering several defeats by the end of the Three Kingdoms period, the Xianbei migrated south and settled in close proximity to Han society and submitted as vassals, being granted the titles of dukes. As the Xianbei Murong, Tuoba, and Duan tribes were one of the Five Barbarians who were vassals of the Western Jin and Eastern Jin dynasties, they took part in the Upheaval of the Five Barbarians, initially as allies of the Jin before dissociating from them and declaring their autonomy. During the Sixteen Kingdoms period, the Xianbei founded several short-lived states in northern China.^[7][8]

The Xianbei were at one point all subjected to the Di-led Former Qin dynasty before it fell apart not long after its defeat in the Battle of Fei River by the Eastern Jin. In the wake of the Former Qin's collapse, the Tuoba formed the Northern Wei dynasty and eventually reunited northern China, ushering China into the Northern and Southern dynasties period. The Northern dynasties, all of which were either led or heavily influenced by the Xianbei, opposed and promoted sinicization at one point or another but trended towards the latter and had merged with the general Chinese population by the Tang dynasty.^{[9][10][11][12][13]} The Northern Wei also arranged for ethnic Han elites to marry daughters of the Tuoba imperial clan in the 480s.^[14] More than fifty percent of Tuoba Xianbei princesses of the Northern Wei were married to southern Han men from the imperial families and aristocrats from southern China of the Southern dynasties who defected and moved north to join the Northern Wei.^[15]
