Donghu (simplified Chinese: 东胡; traditional Chinese: 東胡; pinyin: Dōnghú; Wade–Giles: Tung-hu; IPA: [tʊ́ŋ.xǔ]; lit.'Eastern foreigners or Eastern barbarians') or Hu (Chinese: ; pinyin: ; Wade–Giles: Hu; IPA: [xǔ])[1] was a tribal confederation of nomadic people that was first recorded from the 7th century BCE and was destroyed by the Xiongnu in 150 BCE. They lived in northern Hebei, southeastern Inner Mongolia and the western part of Liaoning, Jilin and Heilongjiang along the Yan Mountains and Greater Khingan Range.[2]



The Classical Chinese name Chinese: literally means "Eastern Barbarians".[3] The term Dōnghú contrasts with the term Xīhú meaning "Western barbarians" (Chinese: 西胡, meaning "non-Chinese peoples in the west" and Five Barbarians 五胡 (Wǔ Hú) "five northern nomadic tribes involved in the Uprising of the Five Barbarians (304–316 CE)". Hill (2009:59) translates Xīhú as "Western Hu" and notes:

The term hu 胡 was used to denote non-Han Chinese populations. It is, rather unsatisfactorily, commonly translated as 'barbarian'. While sometimes it was used in this general way to describe people of non-Han descent, and carried the same negative overtones of the English term, this was not always the case. Most frequently, it was used to denote people, usually of Caucasoid or partial Caucasoid appearance, living to the north and west of China. (2009:453)

In 307 BCE, the 胡 proper, also termed Dōnghú 東胡, were mentioned as a non-Chinese people who were neighbors of Zhao[4][5] and skilled at mounted archery (a military tactic which King Wuling of Zhao would later adopt).[1] However, the term Hu can also refer to a variety of different races and different ethnic groups.[6] It was used by Han Chinese to describe anyone who is not of ethnic Han Chinese descent and were considered barbarians: for example, Sima Qian also used Hu to call the Xiongnu, who were then ruled by Touman chanyu, once expelled by Qin general Meng Tian north from the Ordos Loop, yet able to regain their territory following the Qin Empire's collapse.[1][7] All Hu workmen were famed for their skills at making bows and carts even without specialization.[8][9]

The peoples categorized as the Five Barbarians means "Five Hu" were the Xiongnu, Jie, Xianbei, Di, and Qiang.[10][11] Of these five ethnic groups, the Xiongnu and Xianbei were nomadic peoples from the northern steppes. The ethnic identity of the Xiongnu is uncertain, but the Xianbei appear to have been Mongolic. The Jie, another pastoral people, may have been a branch of the Xiongnu, who may have been Yeniseian[12] or Indo-Scythian.[13] The Di and Qiang were from the highlands of western China.[10] The Qiang were predominantly herdsmen and spoke Sino-Tibetan (Tibeto-Burman) languages, while the Di were farmers who may have spoken a Sino-Tibetan[14] or Turkic language.[15] The traditional explanation, going back to the second-century Han dynasty scholar Cui Hao 崔浩 is that the Donghu were originally located "east of the Xiongnu" who were one of the "Five Barbarians" ().[16] Modern Chinese apologetics suggests that "Donghu" was a transcription of an endonym and did not literally mean "Eastern Barbarian".[17]

The usual English translation of Dōnghú is "Eastern Barbarians" (e.g., Watson, di Cosmo, Pulleyblank, and Yu), and the partial translation "Eastern Hu" is occasionally used (Pulleyblank). Note that "Eastern Barbarians" is also a translation for Dōngyì 東夷, which refers to "ancient peoples in eastern China, Korea, Japan, etc."[clarification needed]

Chinese Sinocentrism differentiates the Huáxià "Chinese" and the "barbarians, non-Chinese, foreigner": this is referred to as the Huá–Yì distinction. Many names besides Hu originally had pejorative "barbarian" meanings, for instance Nanman 南蠻 ("southern barbarians") and Beidi 北狄 ("northern barbarians"). Edwin G. Pulleyblank explains:

At the dawn of history we find the Chinese, self-identified by such terms as Hsia and Hua, surrounded and interspersed by other peoples with whom they were frequently in conflict and whom they typically looked down upon as inferior beings in the same way the Hellenes looked down on the barbaroi and, indeed, as human we-groups have always looked down on their neighbors.[18]

The historian Nicola di Cosmo concludes:

We can thus reasonably say that, by the end of the fourth century B.C., the term "Hu" applied to various ethnic groups (tribes, groups of tribes, and even states) speaking different languages and generally found living scattered across a wide territory. Their fragmentation, however, could be turned, when the need arose, into a superior form of political organization (a "state"). This explains why hu appears often preceded by a qualifier that we may take for a specific ethnic group, as with the Lin Hu and the Tung Hu. Whether or not it had originally been an ethnonym, such a designation had been lost by the Warring States period.[19]

In modern Standard Chinese usage has lost its original meaning although it still appears in words like èrhú 二胡 (lit. "two foreign") "Chinese two-string fiddle", hútáo 胡桃 ("foreign peach") "walnut", and húluóbō 胡萝卜 ("foreign radish") "carrot".


The modern pronunciation Dōnghú differs from the Old Chinese pronunciation, which roughly dates from the Warring States Period (476–221 BCE) when Donghu was first recorded. Old Chinese reconstructions of Dōnghú include *Tûngɣâg,[20] *Tungg'o,[21] *Tewnggaɣ,[22] *Tongga,[23] and *Tôŋgâ > *Toŋgɑ.[24] William H. Baxter and Laurent Sagart (2014)[25] reconstruct the Old Chinese ancestor of as *[g]ˤa. Recently, Christopher Atwood reconstructs a foreign ethnonym *ga, which was borrowed into Old Chinese as 胡 * (> ), while an i-suffixed derivative of *ga underlies two Middle Chinese transcriptions: namely,

The etymology of ethnonym *ga (> 胡 OC * > Ch. ) is unknown.[28] As for *ga's possibly derivation Qay: Golden (2003) proposes several Mongolic etymologies: ɣai "trouble, misfortune, misery", χai "interjection of grief", χai "to seek", χai "to hew", albeit none compelling.[29][30]

Some dictionaries and scholars (e.g. Jean-Pierre Abel-Rémusat) confuse Dōnghú 東胡 with Tungusic peoples, Tonggu 通古. Russian Mongolist Lydia Viktorova states that:

This is due to the insufficient amount of materials and partly due to the mistakes made. For example, the phonetic identification of the ancient people of the Donghu (Eastern Hu) with the Tungus, made at the beginning of the 19th century by Abel-Rémusat only on the principle of sound similarity between Donghu and Tungus. This led to the fact that for a long time all the descendants of the Donghu were considered the ancestors of the Tungus."[31]

This "chance similarity in modern pronunciation", writes Pulleyblank, "led to the once widely held assumption that the Eastern Hu were Tungusic in language. This is a vulgar error with no real foundation."[32]


Lineage of the Donghu (Eastern Hu)
Lineage of the Donghu (Eastern Hu)

Among the northern ethnic groups, the Donghu was the earliest to evolve into a state of civilization and first developed bronze technology. Their culture was associated with the Upper Xiajiadian culture, characterized by the practice of agriculture and animal husbandry supplemented by handicrafts and bronze art.[33] Through the use of cavalry and bronze weaponry in warfare, they dominated over the Xiongnu on their west.[34][35][36][37]

The (ca. 109–91 BCE) Shiji section on Xiongnu history first records the Donghu during the era of Duke Wen of Jin (r. 697–628 BCE) and Duke Mu of Qin (r. ca. 659–621 BCE).

At this time Qin and Jin were the most powerful states in China. Duke Wen of Jin expelled the Di barbarians and drove them into the region west of the Yellow River between the Yun and Luo rivers; there they were known as the Red Di and the White Di. Shortly afterwards, Duke Mu of Qin, having obtained the services of You Yu, succeeded in getting the eight barbarian tribes of the west to submit to his authority.
Thus at this time there lived in the region west of Long the Mianzhu, the Hunrong, and the Diyuan tribes. North of Mts. Qi and Liang and the Jing and Qi rivers lived the Yiqu, Dali, Wuzhi, and Quyuan tribes. North of Jin were the Linhu (Forest Barbarians) and the Loufan, while north of Yan lived the Donghu (Eastern Barbarians) and Shanrong (Mountain Barbarians), each of them with their own chieftains. From time to time they would have gatherings of a hundred or so men, but no one tribe was capable of unifying the others under a single rule.[38]

Donghu raided both Zhao and Yan in the 4th and 3rd centuries BC
Donghu raided both Zhao and Yan in the 4th and 3rd centuries BC

In 307 BC King Wuling of Zhao (born 356 BC, reigned 325-299 BC), a contemporary of Alexander the Great (356-323 BC), instituted a military reform called "Hu clothes, Cavalry archery" after having been repeatedly harassed earlier in his reign by Donghu horse-archers. In 300 BCE Qin Kai, a general taken hostage from the state of Yan (whose capital "Ji" is now Beijing), defeated the Donghu after having gained the esteem of the Donghu and learning their battle tactics. In 273 BC (26th year of King Huiwen) Zhao defeated the Donghu. In 265 BC Li Mu of the Zhao state, one of the four most prominent generals of the Warring States period, defeated the Donghu after stopping a major Xiongnu invasion. By the time of the rule of the Xiongnu Chanyu Touman (c. 220 BCE to 209 BCE), "the Donghu were very powerful and the Yuezhi were likewise flourishing."[39] When the Xiongnu crown prince Modu Chanyu killed his father Touman (in 209 BCE) and took the title of Chanyu, the Donghu thought that Modu feared them, and they started to ask for tribute from the Xiongnu, his best horses and even a consort of Modu's. Modu conceded. Not satisfied with this they asked for some of the Xiongnu territories. This enraged Modu who attacked and soundly defeated them, killing their ruler, taking his subjects prisoner, and seizing their livestock, before turning west to attack and defeat the Yuezhi (c. 177 BCE).[40] This caused disintegration in the Donghu federation. Thereafter, the Wuhuan moved to Mt. Wuhuan and engaged in continuous warfare with the Xiongnu on the west and China on the south. As they came to be worn out from the lengthy battles, the Xianbei preserved their strengths by moving northward to Mt. Xianbei. When the Han dynasty vassal king Lu Wan defected to the Xiongnu in 195 BC he was created King of Donghu (東胡王) by the Xiongnu. This Kingdom of Donghu fiefdom lasted until 144 BC when Lu Wan's grandson Lu Tazhi defected back to the Han Dynasty. The Wuhuan (southern Donghu) inhabitants of the fiefdom continued as vassals of the Xiongnu until 121 BC. Gradually the name Donghu stopped being used. In the 1st century, the Xianbei (northern Donghu) defeated the Wuhuan and northern Xiongnu, and developed into a powerful state under the leadership of their elected Khan, Tanshihuai.[41][42][43][44]

The Book of Jin, published in 648, linked the Donghu and their Xianbei descendants to the Youxiong lineage (有熊氏),[45] associated with the Yellow Emperor[46] and possibly named after the Yellow Emperor's "hereditary principality".[47] However, many non-Han Chinese rulers were claimed to be the Yellow Emperor's descendants, for individual and national prestige.[48][49]

Chinese historian Yu Ying-shih describes the Donghu.

The Tung-hu peoples were probably a tribal federation founded by a number of nomadic peoples, including the Wu-huan and Hsien-pi. After its conquest of the Hsiung-nu, the federation apparently ceased to exist. Throughout the Han period, no trace can be found of activities of the Tung-hu as a political entity.[16]

Di Cosmo says the Chinese considered the Hu 胡 as "a new type of foreigner", and believes, "This term, whatever its origin, soon came to indicate an 'anthropological type' rather than a specific group or tribe, which the records allow us to identify as early steppe nomads. The Hu were the source of the introduction of cavalry in China."[50]

Pulleyblank cites Paul Pelliot that the Donghu, Xianbei, and Wuhuan were "proto-Mongols".

The Eastern Hu, mentioned in the Shih-chi along with the Woods Hu and the Lou-fan as barbarians to the north of Chao in the fourth century B.C., appear again as one of the first peoples whom the Hsiung-nu conquered in establishing their empire. Toward the end of the Former Han, as the Hsiung-nu empire was weakening through internal dissension, the Eastern Hu became rebellious. From then on they played an increasingly prominent role in Chinese frontier strategy as a force to play off against the Hsiung-nu. Two major divisions are distinguished, the Hsien-pei to the north and the Wu-huan to the south. By the end of the first century B.C. these more specific names had supplanted the older generic term.[51]

Pulleyblank also writes that although

there is now archaeological evidence of the spread of pastoral nomadism based on horse riding from Central Asia into Mongolia and farther east in the first half of the first millennium B.C.E., as far as we have evidence it did not impinge on Chinese consciousness until the northward push of the state of Zhao 趙 to the edge of the steppe in present Shanxi province shortly before the end of the fifth century B.C.E. brought them into contact with a new type of horse-riding “barbarian” that they called Hu 胡. … In Han times the term Hu was applied to steppe nomads in general but especially to the Xiongnu who had become the dominant power in the steppe. Earlier it had referred to a specific proto-Mongolian people, now differentiated as the Eastern Hu 東胡, from whom the Xianbei 鮮卑 and the Wuhuan 烏桓 later emerged.[52]


The Dōnghú later divided into the Wuhuan in the Yan Mountains[53] and Xianbei in the Greater Khingan Range:[54][55] the Wuhuan are ancestors of the Kumo Xi,[56][53] while the Xianbei are ancestors of the Khitan[57][55] and the Mongols.[58][59] Another people of Donghu descent were the Rouran (Proto-Mongolic tribe).[60][61]

In the past, scholars such as Fan Zuoguai and Han Feimu also mistakenly[why?] thought that Jurchens (ancestors of the Manchus) descended from the Donghu.[62] In 1980, Russian scholar Lydia Leonidovna Viktorova criticized the 19th century phonetic identification of the ancient people of the Donghu (Eastern Hu) with the Tungus.[31]

A genetic study published in the American Journal of Physical Anthropology detected the paternal haplogroup C2b1a1b among the Xianbei and Rouran. This lineage has also been found among the Donghu. Haplogroup C2b1a1b has a high frequency among Mongols.[63]

A genetic study published in the American Journal of Physical Anthropology in August 2018 detected the paternal haplogroup C2b1a1b among the Xianbei and Rouran. This lineage has also been found among the Donghu.[64] The authors of the study suggested that haplogroup C2b1a1b was an important lineage among the Donghu, and that the Rouran were paternally descended from the Xianbei and Donghu. Haplogroup C2b1a1b has a high frequency among Mongols.[63]
