The Central Asian people who called themselves
Kushana, were among the conquerors of the Greco-Bactrian Kingdom during the 2nd century BC, and are widely believed to have originated as a dynastic clan or tribe of the Yuezhi. The area of Bactria they settled came to be known as
Tokharistan. Because some inhabitants of Bactria became known as
Tukhāra (Sanskrit) or
Tókharoi (Τοχάριοι; Greek), these names later became associated with the Yuezhi. The Kushana spoke
Bactrian, an
Eastern Iranian language.
Bactria In the 3rd century BC, Bactria had been conquered by the Greeks under
Alexander the Great and since settled by the
Hellenistic civilization of the
Seleucids. The resulting
Greco-Bactrian Kingdom lasted until the 2nd century BC. The area came under pressure from various nomadic peoples and the Greek city of
Alexandria on the Oxus was apparently burnt to the ground in about 145 BC. The last Greco-Bactrian king,
Heliocles I, retreated and moved his capital to the Kabul Valley. In about 140–130 BC, the Greco-Bactrian state was conquered by the nomads and dissolved. The Greek geographer
Strabo mentions this event in his account of the central Asian tribes he called "
Scythians": Writing in the 1st century BC, the Roman historian
Pompeius Trogus attributed the destruction of the Greco-Bactrian state to the Sacaraucae and the Asiani "kings of the Tochari". Both Pompeius and the Roman historian
Justin (2nd century AD) record that the Parthian king
Artabanus I was mortally wounded in a war against the Tochari in 124 BC. Several relationships between these tribes and those named in Chinese sources have been proposed, but remain contentious. 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.
Noin-Ula carpets According to Sergey Yatsenko, the carpets with vivid embroidered scenes discovered in
Noin-Ula were made by the Yuezhi in
Bactria, and were obtained by the
Xiongnu through commercial exchange or tributary payment, as the Yuezhi may have remained tributaries of the Xiongnu for a long time following their defeat. Embroidered carpets were among the highest-prized luxury items for the Xiongnu. The figures depicted in the carpets are believed to reflect the clothing and customs of the Yuezhi while they were in Bactria in the 1st century BCE-1st century CE.
In the Hindu Kush The area of the
Hindu Kush (
Paropamisadae) was ruled by the western
Indo-Greek king until the reign of
Hermaeus (reigned –70 BC). 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, who by then had been dominated by
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 AD, when the design blends into the coinage of the
Kushan king
Kujula Kadphises. Such coins may provide the earliest known names of Yuezhi
yabgu (a minor royal title, similar to prince), namely
Sapadbizes and/or
Agesiles, who both lived in or about 20 BC.

Kushan Empire, which was to rule the region for several centuries. Despite their change of name, most Chinese authors continued to refer to the Kushanas as the Yuezhi. The Kushanas expanded to the east during the 1st century AD. The first Kushan emperor,
Kujula Kadphises, ostensibly associated himself with
King Hermaeus on his coins. The Kushanas 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, putting them at the center of the lucrative Central Asian commerce with the
Roman Empire. The Kushanas collaborated militarily with the Chinese against their mutual enemies. This included a campaign 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. In around AD 85, the Kushanas also assisted the Chinese in an attack on
Turpan, east of the Tarim Basin.
stone palette, 1st century AD Following the military support provided to the Han, the Kushan emperor requested a marriage alliance with a
Han princess and sent gifts to the Chinese court in expectation that this would occur. After the Han court refused, a Kushan army 70,000 strong marched on Ban Chao in 86 AD. The army was apparently exhausted by the time it reached its objective and was defeated by the Chinese force. The Kushanas retreated and later paid tribute to the Chinese emperor
Han He (89–106). In about 120 AD, 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. There they introduced the
Brahmi script, the Indian
Prakrit language for administration, and
Greco-Buddhist art, which developed into
Serindian art. ,
Buddha,
Avalokitesvara, and a Kushan Buddhist monk. Following this territorial expansion, the Kushanas introduced
Buddhism to northern and northeastern Asia, by both direct missionary efforts and the translation of Buddhist scriptures into Chinese. Major Kushan missionaries and translators included
Lokaksema (born ) and
Dharmaraksa (), both of whom were influential translators of the
Mahayana sutras into Chinese. They went to China and established translation bureaus, thereby being at the center of the
Silk Road transmission of Buddhism. In the
Records of the Three Kingdoms (chap. 3), it was recorded that in 229 AD, "The king of the Da Yuezhi [Kushanas], 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 (Ch: 親魏大月氏王,
Qīn Wèi Dà Yuèzhī Wáng)." Soon afterwards, the military power of the Kushanas began to decline. The rival
Sasanian Empire of Persia extended its dominion into Bactria during the reign of
Ardashir I around 230 CE. The Sasanians also occupied neighboring
Sogdia by 260 AD and made it into a
satrapy. During the course of the 3rd and 4th centuries, the Kushan Empire was divided and conquered by the Sasanians, the
Hephthalite tribes from the north, and the
Gupta and
Yaudheya empires from India. ==Later references to the Lesser Yuezhi==
