Lanzhou
History

Originally in the territory of the ancient Western Qiangs, Lanzhou became part of the territory of the State of Qin in the 6th century BC.

In 81 BC, under the Han dynasty (206 BC–AD 220), it was taken from the Huns' Huandi Chanyu and made the seat of Jincheng commandery (jùn), and later of the Jincheng (Golden City) county (xiàn), later renamed Yunwu. From at least the first millennium BC it was a major link on the ancient Northern Silk Road, and also an important historic Yellow River crossing site. To protect the city, the Great Wall of China was extended as far as Yumen. Parts of the Great Wall still exist within the built-up area.

After the fall of the Han dynasty, Lanzhou became the capital of a succession of tribal states. In the 4th century it was briefly the capital of the independent state of Liang. The Northern Wei dynasty (386–534) reestablished Jincheng commandery, renaming the county Jincheng. Mixed with different cultural heritages, the area at present-day Gansu province, from the 5th to the 11th century, became a center for Buddhist study. Under the Sui dynasty (581–618) the city became the seat of Lanzhou prefecture for the first time, retaining this name under the Tang dynasty (618–907). In 763 the area was overrun by the Tibetan Empire and in 843 was conquered by the Tang. Later it fell into the hands of the Western Xia dynasty (which flourished in Qinghai from the 11th to 13th century) and was subsequently absorbed by the Song dynasty (960–1126) in 1081. The name Lanzhou was reestablished, and the county renamed Lanzhuan.

After 1127 it fell into the hands of the Jin dynasty, and after 1235 it came into the possession of the Mongol Empire.

Under the Ming dynasty (1368–1644) the prefecture was demoted to a county and placed under the administration of Lintao superior prefecture, but in 1477 Lanzhou was reestablished as a political unit.

The city acquired its current name in 1656, during the Qing dynasty. When Gansu was made a separate province in 1666, Lanzhou became its capital.

In 1739 the seat of Lintao was transferred to Lanzhou, which was later made a superior prefecture called Lanzhou.

Lanzhou was badly damaged during the Dungan revolt in 1864–1875. In the 1920s and 1930s it became a center of Soviet influence in northwestern China.
