How large were the Yuezhi?

At their greatest extent drawn on this map, the Yuezhi covered about 457,000 km². That is the largest area the border data gives them across the years they are drawn, not necessarily their greatest extent in history.

Yuezhi

Nomadic confederation turned sedentary empire progenitor · c. 3rd century BC – 1st century AD (as Yuezhi; thereafter as Kushans)

The Yuezhi (月氏) were an ancient nomadic people first described in Chinese histories as pastoralists in the arid grasslands of western Gansu, controlling the jade trade from the Tarim Basin. Their defeat by the Xiongnu set off a chain of migrations that reshaped Central Asian history for centuries — culminating in their descendants' Kushan Empire.

Overview and identity

Origins and ethnolinguistic background

Pre-Han texts (Guanzi, Yi Zhou Shu, Tale of King Mu) mention jade-supplying peoples — Yúzhī/Niúzhī — plausibly identical with the Yuezhi. Most scholars regard them as Indo-European; the once-popular identification with the Tochari of Greek sources and with the Tocharian languages of the Tarim is now widely questioned (no Tocharian traces exist in Bactrian, the language they adopted in Bactria). Their original homeland is itself debated: "between Dunhuang and Qilian" per the Book of Han, or 1,000 km further northwest, north of the Tian Shan, per some modern authors.

Chronology: from Gansu to Bactria

By the late 3rd century BC the Yuezhi were strong enough to hold the young Modu as a hostage. But Modu's Xiongnu crushed them around 176 BC; chanyu Laoshang later killed a Yuezhi king and "made a drinking cup out of his skull" (Shiji 123). The confederation split: the Lesser Yuezhi moved south to the Qiang on the Tibetan plateau edge, while the Greater Yuezhi migrated (c. 165 BC) to the Ili valley, displacing the Sai (Sakas), only to be expelled by the Wusun in 132 BC. They moved via Dayuan (Ferghana) to the north bank of the Oxus, ruling Bactria (Daxia) as overlords of its "petty chiefs" — a land Zhang Qian found populous (a million people) and commercially sophisticated when he visited in 126 BC seeking an anti-Xiongnu alliance, which the now-contented Yuezhi declined. By the early 1st century BC they were organized in five principalities (xihou): Xiumi, Guishuang (Kushan), Shuangmi, Xidun, and Dumi. Around 30 AD the Guishuang chief Kujula Kadphises subdued the other four and founded the Kushan Empire; Chinese authors nonetheless continued calling the Kushans "Da Yuezhi".

Culture, religion, and archaeology

In Bactria the Yuezhi Hellenized, adopting the Greek alphabet and minting imitations of Greco-Bactrian and Indo-Greek coins (yabgus Sapadbizes and Agesiles/Arseiles, c. 20 BC). Yuezhi envoys gave oral teachings of Buddhist sutras at the Han court as early as 2 BC — among the earliest documented transmissions of Buddhism toward China. Material culture attributed to them includes the royal palace frescoes of Khalchayan (with cranially deformed princes), the gold-rich Tillya Tepe burials, and the embroidered Noin-Ula carpets found in Xiongnu tombs.

The Lesser Yuezhi and legacy

The Lesser Yuezhi persisted among the Qiang, joined the Liangzhou rebellion (184–221 AD), possibly founded the city-state of Cumuḍa (Kumul/Hami), and have been speculatively linked to the Jie of the Later Zhao and the Gar clan of Tibet — all contested. Their enduring significance is as the human vector that carried steppe power, Hellenistic art, and Buddhism across Asia.
