The migrations of the Yuezhi through Central Asia, from around 176 BCE to 30 CE
|Some 100,000 to 200,000 horse archers, according to the Shiji, Chapter 123. The Hanshu Chapter 96A records: 100,000 households, 400,000 people with 100,000 able to bear arms.|

The Yuèzhī or Rouzhi (Chinese: 月氏; pinyin: Yuèzhī; Wade–Giles: Yüeh4-chih1; Old Chinese 月支) were an ancient Indo-European people who were first reported living in an arid grassland area spanning the modern Chinese provinces of Xinjiang and Gansu, before the 2nd century BCE.
After a major defeat by the Xiongnu, the Yuezhi fragmented, during the 2nd Century BCE, into groups that emigrated in different directions. The Greater Yuezhi or Great Yuezhi (Da Yuezhi 大月氏) migrated west through the Tarim Basin into the Ili Valley (on the modern borders of China and Kazakhstan), where they reportedly displaced elements of the Sakas (Scythians). Most members of another group, the Lesser Yuezhi or Little Yuezhi (Xiao Yuezhi 小月氏) reportedly moved south, towards the Tibetan Plateau. The Greater Yuezhi were driven from the Ili Valley by the Wusun and migrated southward to Sogdia and, later, Bactria, where they displaced the Greco-Bactrian Kingdom. The Greater Yuezhi were consequently often identified with the Tókharioi (Greek Τοχάριοι; Sanskrit Tukhāra) and Asii or Asioi mentioned in classical European sources.
During the 1st Century BCE, one of the five major Yuezhi tribes in Bactria, the Kushanas (Chinese: 貴霜; pinyin: Guishuang), began to subsume the other tribes and neighbouring peoples. The subsequent Kushan Empire, at its peak in the 3rd Century CE, stretched from Turfan in the Tarim Basin, in the north to Pataliputra on the Gangetic plain of India in the south. The Kushanas played an important role in the development of trade on the Silk Road and the introduction of Buddhism to China.
There are numerous theories about the origin of the Chinese name "Yuezhi", written with the characters yuè (月) "moon" and shì (氏) "clan", but none has yet found general acceptance. Some scholars, such as Zhang Guang-da, have suggested that the name Yuezhi may be a sinicized transliteration of an endonym, cognate to Visha ("the tribes") or Vèsh ("divisions") in Eastern Iranian languages; or Vijaya ("victory" in Indo-Aryan languages). This theory has not been widely accepted.
The relationship between the Yuezhi and other Indo-European peoples who lived in China and Central Asia is often unclear. The Kushanas, who were among the conquerors of the Greco-Bactrian Kingdom during the 2nd century b.c., are widely believed to have originated as a dynastic clan or tribe of the Yuezhi. Because some inhabitants of Bactria became known as Tukhāra (Sanskrit) or Tókharoi (Τοχάριοι; Greek) and these names became retrospectively associated with the Yuezhi.
When manuscripts dating from the a.d. 6th to 8th centuries, and written in two hitherto-unknown centum-type, non-Iranian languages, were discovered in the northern Tarim Basin, the early 20th Century linguist Friedrich W. K. Müller assumed that the authors were Tókharoi and referred to the newly-discovered languages as "Tocharian". This became the common name for both the languages of the Tarim manuscripts and the people who produced them. Most historians now reject the identification of the Tókharoi of Bactria with the Tocharians of the Tarim, because the Tókharoi are not known to have spoken any languages other than Bactrian: a satem-type, Eastern Iranian language. Other scholars suggest, however, that the Kushanas may be an example of an invading or colonising elite adopting a local language. That is, they did not necessarily speak Bactrian before arriving in Bactria, and they may previously have spoken the Tocharian languages of the Tarim. In support of this claim, Christopher Beckwith argues that the character 月, usually read as Old Chinese *ŋʷjat > modern yuè, could have been pronounced in an archaic northwestern dialect as *tokwar or *togwar, a form that resembles the Bactrian name Toχοαρ (Toχwar ~ Tuχwar) and the medieval form Toχar ~ Toχâr. Likewise, Craig Benjamin points out that "the problem of identifying the Yuezhi ... intersects history and language, since they may have spoken the centum Indo-European language variant of Tokharian."
Theories on origins
The Yuezhi may have been an Europoid people, as indicated by the portraits of their kings on the coins that were struck following their exodus to Transoxiana (2nd–1st century BCE), portraits from statues in Khalchayan, Bactria in the 1st century BCE, some old place names in Gansu explainable in Tocharian languages, and especially the coins which they struck in India as Kushans (1st–3rd century CE).
According to one theory, the Yuezhi were connected to a large migration of Indo-European-speaking peoples from eastern Central Asia in the Bronze Age. These were possibly ethnic Tocharian speakers and connected to the Afanasevo culture. Very well preserved Tarim mummies from the 18th century BCE to the first centuries BCE with Europoid features (light hair and eyes) and dominated by the Y-DNA haplogroup R1a1 have been found in the Tarim Basin. One mummy today displayed at the Ürümqi Museum and dated from the 3rd century BCE, found at the ancient oasis on the Silk Road, Niya, has been connected to the Yuezhi. Evidence of the Indo-European Tocharian languages also has been found in the same geographical area. Although the first known epigraphic evidence dates to the 6th Century CE, the degree of differentiation between Tocharian A and Tocharian B and the absence of Tocharian language remains beyond that area suggest that a common Tocharian language existed in the same area of Yuezhi settlement during the second half of the 1st millennium BCE.
Esther Jacobson emphasizes that "the Yuezhi/Kushans may properly be considered to have belonged to the larger Scytho-Siberian culture." The nomadic people, probably Scythians, of the Ordos culture of the Ordos Plateau, who lived in northern China, east of the Yuezhi, are another of a later similar migration. According to some scholars the Yuezhi might themselves have been Scythians. The Yuezhi (Rouzhi) are associated by some scholars with the Ordos culture. Also, the Europoid mummies of Pazyryk, which were probably Scythian in origin, were found around 1,500 kilometers northwest of the Yuezhi and date to around the 3rd century BCE. The Pazyryk burials coincide with the apex of Yuezhi power, and have been connected to the Yuezhi by some scholars.
The Yuezhi are described in ancient Chinese historical accounts. They may have been mentioned by Sima Qian, who described how the first Qin emperor, Qin Shi Huang (reigned 246-210 BCE) had dealt with a man named Luo – leader of a people called Wuzhi (sic) – in the trade of both jade and horses. Sima Qian also makes the first clear reference to the Yuezhi, saying that – in the 2nd Century BCE – "The Yuezhi originally lived in the area between the Qilian or Heavenly Mountains and Dunhuang." (Records of the Great Historian, or Shiji; "The Account of Dayuan", 123). While the area between the Qilian and Dunhuang lies in the modern Chinese province of Gansu, some scholars have argued that "Dunhuang" should be Dunhong, a mountain in the Tian Shan, and have placed the original homeland of the Yuezhi 1,000 km further west (in the northern part of modern Xinjiang). 
A text known as the Guanzi (73, 78, 80 and 81) described how nomadic pastoralists called the Yúshì 禺氏 or Niúshì 牛氏 had supplied jade to the Chinese. The supply of Tarim Basin jade from ancient times is well documented archaeologically. The hundreds of jade pieces found in the tomb of Fuhao from the late Shang dynasty all originated from Khotan, on the southern rim of the Tarim Basin. According to the Guanzi, the peoples of the Tarim, unlike the neighbouring Xiongnu, did not engage in conflict with nearby Han Chinese states.
During the Warring States period (5th to 3rd centuries BCE) the Chinese also turned to the Yuezhi for the supply of good horses. Moreover, the Yuezhi supplied the Qin Empire with crucial military mounts. The Yuezhi maintained a profitable trade of horses and cattle for Chinese silk, which they sold on to their neighbours. Thus the Yuezhi began the Silk Road trade, acting as intermediaries between China and Central Asia.
However, the Yuezhi were regularly in conflict with the Xiongnu. Around 210 BCE, the Xiongnu king Touman gave his son Modu as hostage to the Yuezhi and then attacked them, hoping they would kill Modu, leaving the succession open to Modu's younger brother. However Modu escaped by stealing a fast horse. He subsequently killed his father and became ruler of the Xiongnu.
Exodus of the Great Yuezhi
Shortly before 176 BCE, led by one of Modu's tribal chiefs, the Xiongnu invaded Yuezhi territory in the Gansu region and achieved a crushing victory. Modu boasted in a letter (174 BCE) to the Han emperor that due to "the excellence of his fighting men, and the strength of his horses, he has succeeded in wiping out the Yuezhi, slaughtering or forcing to submission every number of the tribe." The son of Modu, Laoshang Chanyu, subsequently killed the king of the Yuezhi and, in accordance with nomadic traditions, "made a drinking cup out of his skull." (Shiji 123.)
According to Chinese sources, elements of the Yuezhi settled in the Tarim Basin, under the domination of the Xiongnu. Some may have been, in part, the ancestors of the Tocharian cultures first attested in the 6th century CE.
It was around this time that the Yuezhi split into two confederations: the so-called Great or Greater Yuezhi (Da Yuezhi) and the Lesser or Little Yuezhi (Xiao Yuezhi).
Da Yuezhi began migrating north-west from the Tarim Basin circa 165 BCE, first settling in the Ili valley, immediately north of the Tian Shan mountains, where they defeated the Sai (Scythians): "The Yuezhi attacked the king of the Sai who moved a considerable distance to the south and the Yuezhi then occupied his lands" (Han Shu 61 4B). This was "the first historically recorded movement of peoples originating in the high plateaus of Asia." (The Sai then undertook their own migration, which was to lead them as far as Kashmir, after travelling through a "Suspended Crossing" (probably the Khunjerab Pass between present-day Xinjiang and northern Pakistan). The Sakas ultimately established an Indo-Scythian kingdom in northern India.) In 132 BCE the Wusun, in alliance with the Xiongnu and out of revenge from an earlier conflict, again managed to dislodge the Yuezhi, forcing them to move south-west. The Yuezhi passed through the neighbouring urban civilization of Dayuan (in Ferghana) and settled on the northern bank of the Oxus, in the region of Transoxiana (modern Tajikistan and Uzbekistan), just north of the Hellenistic Greco-Bactrian Kingdom. The Greek city of Alexandria on the Oxus was apparently burnt to the ground by the Yuezhi around 145 BCE.
Yuezhi settlement in Central Asia
The Yuezhi were visited in Transoxiana by a Chinese mission, led by Zhang Qian in 126 BCE, which sought an offensive alliance with the Yuezhi against the Xiongnu. Zhang Qian, who spent a year in Transoxiana and Bactria, wrote a detailed account in the Shiji, which gives considerable insight into the situation in Central Asia at the time. The request for an alliance was denied by the son of the slain Yuezhi king, who preferred to maintain peace in Transoxiana rather than seek revenge.
Zhang Qian also reported that "the Great Yuezhi live 2,000 or 3,000 li (832–1,247 kilometers) west of Dayuan, north of the Gui [Oxus ] river. They are bordered on the south by Daxia [Bactria], on the west by Anxi [Parthia], and on the north by Kangju [beyond the middle Jaxartes/Syr Darya]. They are a nation of nomads, moving from place to place with their herds, and their customs are like those of the Xiongnu. They have some 100,000 or 200,000 archer warriors." (Shiji 123.)
In a sweeping analysis of the physical types and cultures of Central Asia, Zhang Qian reports that "although the states from Dayuan west to Anxi (Parthia), speak rather different languages, their customs are generally similar and their languages mutually intelligible. The men have deep-set eyes and profuse beards and whiskers. They are skilful at commerce and will haggle over a fraction of a cent. Women are held in great respect, and the men make decisions on the advice of their women." (Shiji 123.)
- During the war against the Tochari, he (Artabanus) was wounded in the arm and died immediately" (Justin, Epitomes, XLII,2,2: "Bello Tochariis inlato, in bracchio vulneratus statim decedit"). Pompeius Trogus also mentions that Artabanus II was mortally wounded by the Tokhari.
Some time after 124 BCE, possibly following further incursions from the north – and apparently also following a defeat by the Parthian king Mithridates II, successor to Artabanus – the Yuezhi moved south to Bactria. (Two centuries earlier, Bactria had been conquered by the Greeks under Alexander the Great and since settled by the Hellenistic civilization of the Seleucids and the Greco-Bactrians.) This event is recorded in Classical Greek sources, when Strabo – who tended to refer to all central Asian tribes as "Scythians" – explained that these tribes had caused the destruction of the Greco-Bactrian kingdom in the second half of the 2nd Century BCE:
- Most of the Scythians, beginning from the Caspian Sea, are called Dahae ... and those situated more towards the east Massagetae and Sacae; the rest have the common appellation of Scythians, but each separate tribe has its peculiar name. All, or the greatest part of them, are nomads. The best known tribes are those who deprived the Greeks of Bactriana, the Asii, Pasiani, Tochari, and Sacarauli, who came from the country on the other side of the Jaxartes, opposite the Sacae and Sogdiani.
The Yuezhi appear to have quickly obtained the submission of the Greco-Bactrians. At the time, the Yuezhi were organized into five major tribes, each led by a yabgu, or tribal chief. These tribes were known to the Chinese as:
- Xiūmì (休密) in Western Wakhān and Zibak;
- Guishuang (貴霜) in Badakhshan and adjoining territories north of the Oxus;
- Shuangmi (雙靡) in the region of Shughnan;
- Xidun (肸頓) in the region of Balkh, and;
- Dūmì (都密) in the region of Termez.
A description of the Greco-Bactrian kingdom was made by Zhang Qian after the area's conquest by the Yuezhi:
- "Daxia [Greco-Bactria] is located over 2,000 li southwest of Dayuan, south of the Gui (Oxus) river. Its people cultivate the land and have cities and houses. Their customs are like those of Ta-Yuan. It has no great ruler but only a number of petty chiefs ruling the various cities. The people are poor in the use of arms and afraid of battle, but they are clever at commerce. After the Great Yuezhi moved west and attacked the lands, the entire country came under their sway. The population of the country is large, numbering some 1,000,000 or more persons. The capital is called the city of Lanshi [most likely Bactra/Balkh] and has a market where all sorts of goods are bought and sold."(Shiji 123.)
After they settled in Bactria, the Yuezhi became Hellenized to some degree – as shown by their adoption of the Greek alphabet and by some remaining coins, minted in the style of the Greco-Bactrian kings, with the text in Greek. The area of Bactria they settled came to be known as Tokharistan and the Yuezhi were known as Tókharoi by the Greeks.
Commercial relations with China also flourished, as many Chinese missions were sent throughout the 1st Century BCE: "The largest of these embassies to foreign states numbered several hundred persons, while even the smaller parties included over 100 members ... In the course of one year anywhere from five to six to over ten parties would be sent out." (Shiji, trans. Burton Watson).
The Hou Hanshu also records the visit of Yuezhi envoys to the Chinese capital in 2 BCE, who gave oral teachings on Buddhist sutras to a student, suggesting that some Yuezhi already followed the Buddhist faith during the 1st century BCE (Baldev Kumar (1973)).
A later Chinese annotation in Zhang Shoujie's Shiji, quoting Wan Zhen's s (萬震) Strange Things from the Southern Region (Nanzhouzhi (南州志), a now-lost 3rd Century text from the Wu kingdom), describes the Kushans as living in the same general area north of India, in cities of Greco-Roman style, and with sophisticated handicraft. The quotes are dubious, as Wan Zhen probably never visited the Yuezhi kingdom through the Silk Road, though he might have gathered his information from the trading ports in the coastal south. The Chinese never adopted the term Guishuang and continued to call them Yuezhi:
- The Great Yuezhi are located about seven thousand li (about 3000 km) north of India. Their land is at a high altitude; the climate is dry; the region is remote. The king of the state calls himself "son of heaven". There are so many riding horses in that country that the number often reaches several hundred thousand. City layouts and palaces are quite similar to those of Daqin [the Roman Empire]. The skin of the people there is reddish white. People are skilful at horse archery. Local products, rarities, treasures, clothing, and upholstery are very good, and even India cannot compare with it.
The area of the Hindu Kush (Paropamisadae) was ruled by the western Indo-Greek king until the reign of Hermaeus (reigned c. 90 BCE–70 BCE). After that date, no Indo-Greek kings are known in the area. According to Bopearachchi, no trace of Indo-Scythian occupation (nor coins of major Indo-Scythian rulers such as Maues or Azes I) have been found in the Paropamisade and western Gandhara. The Hindu Kush may have been subsumed by the Yuezhi,[original research?] who by then had had dominated Greco-Bactria for almost two centuries.
As they had done in Bactria with their copying of Greco-Bactrian coinage, the Yuezhi copied the coinage of Hermeaus on a vast scale, up to around 40 CE, when the design blends into the coinage of the Kushan king Kujula Kadphises. Such coins provide the earliest names of presumed Yuezhi princes, Sapadbizes (probably a yabgu's prince of Yuezhi confederation[original research?]) and Agesiles, both around 20 BCE.
By the end of the 1st Century BCE, one of the five tribes of the Yuezhi, the Guishuang (貴霜, origin of name Kushan adopted in the West), managed to take control of the Yuezhi confederation. From that point, the Yuezhi extended their control over the northwestern area of the Indian subcontinent, founding the Kushan Empire, which was to rule the region for several centuries. The Yuezhi came to be known as Kushan among Western civilizations; however, the Chinese kept calling them Yuezhi throughout their historical records over a period of several centuries.
The Yuezhi/Kushans expanded to the east during the 1st century CE to found the Kushan Empire. The first Kushan emperor, Kujula Kadphises, ostensibly associated himself with King Hermaeus on his coins, suggesting that he may have been one of the king's descendants by alliance, or at least wanted to claim his legacy.
The unification of the Yuezhi tribes and the rise of the Kushan are documented in the Chinese Historical chronicle, the Hou Hanshu:
- "More than a hundred years later, the xihou (Ch:翖侯, "Allied Prince") of Guishuang (Badakhshan and the adjoining territories north of the Oxus), named Qiujiu Que (Ch: 丘就卻, Kujula Kadphises) attacked and exterminated the four other xihou ("Allied Princes"). He set himself up as king of a kingdom called Guishuang (Kushan). He invaded Anxi (Parthia) and took the Gaofu (Ch:高附, Kabul) region. He also defeated the whole of the kingdoms of Puda (Ch: 濮達) and Jibin (Ch: 罽賓, Kapiśa-Gandhāra). Qiujiu Que (Kujula Kadphises) was more than eighty years old when he died.
- "His son, Yan Gaozhen (Ch:閻高珍) (Vima Takto), became king in his place. He returned and defeated Tianzhu (Northwestern India) and installed a General to supervise and lead it. The Yuezhi then became extremely rich. All the kingdoms call [their king] the Guishuang (Kushan) king, but the Han call them by their original name, Da Yuezhi." (Hou Hanshu, trans. John Hill,).
The Yuezhi/Kushan integrated Buddhism into a pantheon of many deities and became great promoters of Mahayana Buddhism, and their interactions with Greek civilization helped the Gandharan culture and Greco-Buddhism flourish.
During the 1st and 2nd centuries, the Kushan Empire expanded militarily to the north and occupied parts of the Tarim Basin, their original grounds, putting them at the center of the lucrative Central Asian commerce with the Roman Empire. When the Han Dynasty desired to advance north, Emperor Wu sent the explorer Zhang Qian to see the kingdoms to the west and to ally with the Yuezhi people, in order to fight the Xiongnu tribe. The Yuezhi continued to collaborate militarily with the Chinese against nomadic incursion, particularly with the Chinese general Ban Chao against the Sogdians in 84 CE when the latter were trying to support a revolt by the king of Kashgar. Around 85 CE, they also assisted the Chinese general in an attack on Turpan, east of the Tarim Basin.
In recognition of their support to the Chinese, the Kushans requested, but were denied, a Han princess, even after they had sent presents to the Chinese court. In retaliation, they marched on Ban Chao in 86 CE with a force of 70,000 but, exhausted by the expedition, were finally defeated by the smaller Chinese force. The Kushans retreated and paid tribute to the Chinese Empire during the reign of the Chinese emperor Han He (89–106).
About 120 CE, Kushan troops installed Chenpan—a prince who had been sent as a hostage to them and had become a favorite of the Kushan Emperor—on the throne of Kashgar, thus expanding their power and influence in the Tarim Basin, and introduced the Brahmi script, the Indian Prakrit language for administration, and Greco-Buddhist art, which developed into Serindian art.
Benefiting from this territorial expansion, the Yuezhi/Kushans were among the first to introduce Buddhism to northern and northeastern Asia, by direct missionary efforts and the translation of Buddhist scriptures into Chinese. Major Yuezhi missionaries and translators included Lokaksema and Dharmaraksa, who went to China and established translation bureaus, thereby being at the center of the Silk Road transmission of Buddhism.
The Chinese kept referring to the Kushans as Da Yuezhi throughout the centuries. In the Sanguozhi (三國志, chap. 3), it is recorded that in 229 CE, "The king of the Da Yuezhi, Bodiao 波調 (Vasudeva I), sent his envoy to present tribute, and His Majesty (Emperor Cao Rui) granted him the title of King of the Da Yuezhi Intimate with the Wei (魏) (Ch: 親魏大月氏王, Qīn Wèi Dà Yuèzhī Wáng)."
The Sasanian Empire extended their dominion into Bactria during the reign of Ardashir I around 230 CE. The Sasanians also occupied neighboring Sogdia by 260 CE and made it into a satrapy. Over the course of the 3rd century AD, the Kushan realm was divided and conquered by the rival Sasanian Empire of Persia, the Gupta Empire of India, and the Hephthalite Empire.
Later references to the Lesser Yuezhi
The Lesser Yuezhi (Xiao Yuezhi) appear to have been quite numerous and some evidently remained in Gansu. For instance, between 184 AD and 221 AD there was a serious revolt by the Lesser Yuezhi in Gansu, which could not be suppressed by the Chinese government.
According to some Chinese sources, some of the Lesser Yuezhi were the basis of the Jie people, who established the Later Zhao state under Shi Le. However, other theories link the Jie to the Xiongnu, Kangju, the Tocharians or Greater Yuezhi. The Jie were mostly massacred by King Ran Min of Ran Wei (modern Hebei), during the Wei–Jie war, of the mid-4th Century.
Some of the Lesser Yuezhi (Xiao Yuezhi) are said to have settled near Lop Nur, in the eastern Tarim basin, where they founded Cumuḍa (also known as Cimuda, Cunuda; Chinese Zhongyun, Tchong-yun; Uyghur Čungul, Xungul), later known as Kumul and Hami (哈密; pinyin Hāmì).
In Tibet, the Lesser Yuezhi constituted the Gar or Mgar – a clan name associated with blacksmiths. The Gar became influential during the period of the Tibetan Empire – until the end of the 7th Century, when 2,000 of them were massacred by the Tibetan emperor Tridu Songtsän.
A Chinese monk named Gao Juhui, who traveled to the Tarim Basin in the 10th Century, stated that the "people named as Zhongyun (or Čungul)" were descendants of the Xiao Yuezhi" and that the king of Zhongyun still resided in "the Hulu desert" near Lop Nur.

The most western of the Early Nomads' relatives and those most familiar to the modern observer were Scythians. They are believed to have arrived in the lands of the Caucasus, the Crimea, and the rich steppe north of the Black Sea by the sixth century B.C. ... In the late years of the first millennium B.C., the successors to the Early Nomads and Sakas served as the vehicles for the transformation of Eurasian nomadism into statehood. The Xiongnu of Mongolia gathered an array of nomadic peoples together into a confederation which became the major geopolitical opponent of the Chinese Han Dynasty. In the same period, the second and first centuries B.C., the Yuezhi established hegemony over the vital steppe region west of the borders of Han China and extending through Bactria to the borders of India. Indeed, after their conversion to Buddhism, the Yuezhi- by then known as the Kushans- proceeded to conquer India and to establish the great Kushan Dynasty. Despite these political transformations and despite significant distinctions in language and physical anthropology between the Xiongnu and their Early Nomadic relatives, they as well as the Yuezhi/Kushans may properly be considered to have belonged to the larger Scytho-Siberian culture.
