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 likely not of a single ethnicity, but rather a multilingual, multi-ethnic confederation consisting of mainly Proto-Mongols (who spoke either pre-Proto-Mongolic, or Para-Mongolic languages), and, to a minor degree, Tungusic and Turkic peoples. 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 direct contact with the Han dynasty, residing to the north of the Wuhuan. In the first century BC, the Xianbei began actively engaging in the struggle between the Han and Xiongnu, culminating in the Xianbei replacing the Xiongnu on the Mongolian Plateau.

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 to the Chinese dynasties. As one of the so-called "Five Barbarians" that settled in northern China, the Xianbei fought as auxiliaries for the Western Jin dynasty during the War of the Eight Princes and the Upheaval of the Five Barbarians before eventually distancing themselves and declaring their autonomy as the Jin were pushed to the south. During the Sixteen Kingdoms period, the Xianbei founded several short-lived states in the north and established themselves on the Central Plains.

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. The Northern Wei also arranged for ethnic Han elites to marry daughters of the Tuoba imperial clan in the 480s. 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.

Paul Pelliot tentatively reconstructs the Eastern Han Chinese pronunciation of 鮮卑 as */serbi/, from *Särpi, after noting that Chinese scribes used 鮮 to transcribe Middle Persian sēr (lion) and 卑 to transcribe foreign syllable /pi/; for instance, Sanskrit गोपी gopī "milkmaid, cowherdess" became Middle Chinese 瞿卑 (ɡɨo-piᴇ) (> Mand. qúbēi).

On the one hand, *Särpi may be linked to the Mongolic root *ser ~*sir which means "crest, bristle, sticking out, projecting, etc." (cf. Khalkha сэрвэн serven), possibly referring to the Xianbei's horses (semantically analogous with the Turkic ethnonym Yabaqu < Yapağu 'matted hair or wool', later 'a matted-haired animal, i.e. a colt'). On the other hand, the Book of the Later Han and the Book of Wei stated that before becoming an ethnonym, Xianbei had been a toponym, referring to the Great Xianbei mountains (大鮮卑山), which is now identified as the Greater Khingan range (simplified Chinese: 大兴安岭; traditional Chinese: 大興安嶺; pinyin: Dà Xīng'ān Lǐng).

Schuessler (2014) reconstructs 鮮卑's Old Chinese pronunciation in the 1st century BCE as *sen-pe, and Eastern Han Chinese pronunciation as sian pie; while reconstructing no syllable coda -r for 鮮's pronunciation in any of those two stages, Schuessler remarks that "[i]n syllable-final position n represents foreign n as well as r and perhaps l", and still derives both *sian pie and *sen-pe from foreign *Särbi.

Shimunek (2018) reconstructs *serbi for Xiānbēi and *širwi for 室韋 Shìwéi < MC *ɕiɪt̚-ɦʉi.

Warring States period's Chinese literature contains early mentions of Xianbei, as in the poem The Great Summons in the anthology Chu Ci and possibly the chapter "Discourses of Jin 8" in the Guoyu.
