The Tuoba (Chinese) or Tabgatch (, Tabγač), also known by other names, was an influential Xianbei clan in early imperial China. During the Sixteen Kingdoms after the fall of Han and the Three Kingdoms, the Tuoba established and ruled the Dai state in northern China. The dynasty ruled from 310 to 376 and then was restored in 386. The same year, the dynasty was renamed Wei, later distinguished in Chinese historiography as the Northern Wei. This powerful state gained control of most of northern China, supporting Buddhism while increasingly sinicizing. As part of this process, in 496, the Emperor Xiaowen changed the imperial clan's surname from Tuoba to Yuan (Chinese: {{linktext|元). The empire split into Eastern Wei and Western Wei in 535, with the Western Wei's rulers briefly resuming use of the Tuoba name in 554.
A branch of the Tanguts also bore a surname transcribed as Tuoba before their chieftains were given the Chinese surnames Li (Chinese: {{linktext|李) and Zhao (Chinese: {{linktext|趙) by the Tang and Song dynasties respectively. Some of these Tangut Tuobas later adopted the surname Weiming (Chinese: {{linktext|嵬名), with this branch eventually establishing and ruling the Western Xia in northwestern China from 1038 to 1227.
By the 8th century, the Old Turkic form of the name was Tabγač ({{linktext|), usually anglicized as Tabgatch or Tabgach. The name appears in other Central Asian accounts as Tabghāj and Taugash and in Byzantine Greek sources like Theophylact Simocatta's History as Taugas (Greek, Ancient (to 1453);: Ταυγάς) and Taugast (Greek, Ancient (to 1453);: Ταυγάστ). Zhang Xushan and others have argued for the name's ultimate derivation from a transcription into Turkic languages of the Chinese name "Great Han" Dà Hàn, .
Tuoba is the atonal pinyin romanization of the Mandarin pronunciation of the Chinese Chinese: {{linktext|拓跋 (Tuòbá), whose pronunciation at the time of its transcription into Middle Chinese has been reconstructed as *tʰak-bɛt or *Thak-bat. The same name also appears with the first character transcribed as Chinese: {{linktext|托 or Chinese: {{linktext|㩉[1] and with the second character transcribed as Chinese: {{linktext|拔; it has also been anglicized as T'o-pa[2] and as Toba. The name is also attested as Tufa (Chinese: {{linktext|禿髮, Tūfà or Tūfǎ),[3] whose Middle Chinese pronunciation has been reconstructed as *tʰuwk-pjot, *T'ak-bwat, or *T'ak-buat. The name is also sometimes clarified as the Tuoba Xianbei (Chinese: 拓跋{{linktext|鮮卑, Tuòbá Xiānbēi).
See main article: Tuoba language. According to Hyacinth (Bichurin), an early 19th-century scholar, the Tuoba and their Rouran enemies descended from common ancestors.[4] The Weishu stated that the Rourans were of Donghu origins[5] [6] and the Tuoba originated from the Xianbei,[7] [8] who were also Donghu's descendants.[9] [10] The Donghu ancestors of Tuoba and Rouran were most likely proto-Mongols.[11] Nomadic confederations of Inner Asia were often linguistically diverse, and Tuoba Wei comprised the para-Mongolic Tuoba as well as assimilated Turkic peoples such as Hegu (紇骨) and Yizhan (乙旃); consequently, about one quarter of the Tuoba tribal confederation was composed of Dingling elements as Tuoba migrated from northeastern Mongolia to northern China.[12]
Alexander Vovin (2007) identifies the Tuoba language as a Mongolic language.[13] [14] On the other hand, Juha Janhunen proposed that the Tuoba might have spoken an Oghur Turkic language.[15] René Grousset, writing in the early 20th century, identifies the Tuoba as a Turkic tribe.[16] According to Peter Boodberg, a 20th-century scholar, the Tuoba language was essentially Turkic with Mongolic admixture.[17] Chen Sanping observed that the Tuoba language contains both elements.[18] [19] Liu Xueyao stated that the Tuoba may have had their own language which should not be assumed to be identical with any other known languages. Andrew Shimunek (2017) classifies Tuoba (Tabghach) as a "Serbi" (i.e., para-Mongolic) language. Shimunek's Serbi branch also consists of the Tuyuhun and Khitan languages.[20]
The Tuoba were a Xianbei clan.[21] [22] The distribution of the Xianbei people ranged from present day Northeast China to Mongolia, and the Tuoba were one of the largest clans among the western Xianbei, ranging from present day Shanxi province and westward and northwestward. They established the state of Dai from 310 to 376 AD[23] and ruled as the Northern Wei from 386 to 536. The Tuoba states of Dai and Northern Wei also claimed to possess the quality of earth in the Chinese Wu Xing theory. All the chieftains of the Tuoba were revered as emperors in the Book of Wei and the History of the Northern Dynasties.
The Northern Wei started to arrange for Chinese elites to marry daughters of the Xianbei Tuoba royal family in the 480s.[24] More than fifty percent of Tuoba Xianbei princesses of the Northern Wei were married to southern Chinese men from the imperial families and aristocrats from southern China of the Southern dynasties who defected and moved north to join the Northern Wei.[25] Some Chinese exiled royalty fled from southern China and defected to the Xianbei. Several daughters of the Xianbei Tuoba Emperor Xiaowen of Northern Wei were married to Chinese elites: the Han Chinese Liu Song royal married of the Northern Wei;[26] [27] [28] [29] [30] married, a descendant of Jin dynasty (266–420) royalty; married ; and married Xiao Baoyin (萧宝夤), a member of Southern Qi royalty.[31] Emperor Xiaozhuang of Northern Wei's sister the Shouyang Princess was wedded to Emperor Wu of Liang's son .[32] One of Emperor Xiaowu of Northern Wei's sisters was married to Zhang Huan, a Han Chinese, according to the Book of Zhou (Zhoushu). His name is given as Zhang Xin in the Book of Northern Qi (Bei Qishu) and History of the Northern Dynasties (Beishi) which mention his marriage to a Xianbei princess of Wei. His personal name was changed due to a naming taboo on the emperor's name. He was the son of Zhang Qiong.[33]
When the Eastern Jin dynasty ended, Northern Wei received the Han Chinese Jin prince as a refugee. A Northern Wei Princess married Sima Chuzhi, giving birth to Sima Jinlong (司馬金龍). Northern Liang Xiongnu King Juqu Mujian's daughter married Sima Jinlong.[34]
According to Zhou (2006) the haplogroup frequencies of the Tuoba Xianbei were 43.75% haplogroup D, 31.25% haplogroup C, 12.5% haplogroup B, 6.25% haplogroup A and 6.25% "other."[35]
Zhou (2014) obtained mitochondrial DNA analysis from 17 Tuoba Xianbei, which indicated that these specimens were, similarly, completely East Asian in their maternal origins, belonging to haplogroups D, C, B, A and haplogroup G.[36]

As a consequence of the Northern Wei's extensive contacts with Central Asia, Turkic sources identified Tabgach, also transcribed as Tawjach, Tawġač, Tamghaj, Tamghach, Tafgaj, and Tabghaj, as the ruler or country of China until the 13th century.
The Orkhon inscriptions in the Orkhon Valley in modern-day Mongolia from the 8th century identify Tabgach as China.
See also: Bain Tsokto inscriptions. In the 11th century text, the Dīwān Lughāt al-Turk ("Compendium of the languages of the Turks"), Turkic scholar Mahmud al-Kashgari, writing in Baghdad for an Arabic audience, describes Tawjach as one of the three components comprising China. At the time of his writing, China's northern fringe was ruled by Khitan-led Liao dynasty while the remainder of China proper was ruled by the Northern Song dynasty. Arab sources used Sīn (Persian: Chīn) to refer to northern China and Māsīn (Persian: Machīn) to represent southern China. In his account, al-Kashgari refers to his homeland, around Kashgar, then part of the Kara-Khanid Khanate, as Lower China.The rulers of the Karakanids adopted Tamghaj Khan (Turkic: the Khan of China) in their title, and minted coins bearing this title.[38] Much of the realm of the Karakhanids including Transoxania and the western Tarim Basin had been under the rule of the Tang dynasty prior to the Battle of Talas in 751, and the Karakhanids continued to identify with China, several centuries later.[38]
The Tabgatch name for the political entity has also been translated into Chinese as Taohuashi .[39] This name has been used in China in recent years to promote ethnic unity.[40] [41]
