nomadic confederation · Central Asia and the Steppe

Kangju

200 BCE – 450 CE (approx.) · capital Beitian

A long-lived nomad kingdom of the middle Syr Darya, a rival of the Wusun and Dayuan that dominated the steppe north of Sogdiana for six centuries.

Origins

Kangju first appears in the account of the Han envoy Zhang Qian, who passed through around 128 BCE and reported a nomadic state north-west of Dayuan with some 80,000 to 90,000 archers. Its people were Iranian-speaking pastoralists on the middle Syr Darya and the Talas and Chu valleys, part of the wider Saka world.

Rule and society

According to the Han histories, the king had his seat at the city of Beitian and a separate winter residence, with five lesser kings beneath him. Kangju controlled routes between the steppe, Sogdiana and the Kingdom of Dayuan, and at times held Sogdian towns as dependencies. In 36 BCE it sheltered the Xiongnu chanyu Zhizhi, whom a Han army killed there.

Decline and legacy

Kangju is linked by archaeologists to the Kaunchi and Otrar-Karatau cultures. It weakened under pressure from the Kidarite Kingdom, Hephthalites and Rouran, and by the 5th century its name passed to Sogdiana itself, 'Kang' being the later Chinese name for Samarkand.

Few sources survive for this state; details are uncertain.
