When, how and where did the Han people enter Xinjiang before the Qing Dynasty?

The Han people entered Xinjiang very early, and the legend of West Zhou Muwang was the first Central Plains figure to visit Xinjiang. After that, the strength of ethnic minorities in the west grew, and the Central Plains regime never set foot in Xinjiang again.

During the period of Emperor Wu of the Western Han Dynasty, Zhang Qian first entered Xinjiang.

Since then, the Han people have maintained good contacts with countries here and opened up the Silk Road. In order to resist the harassment of the Huns to the Han Dynasty and the western corridor, the Han people had a certain number of troops and service people in this area, and the Han people did not settle here on a large scale.

After the Han Dynasty, the ethnic minorities in the west and north grew again, and the Han regime in the Central Plains was unable to re-enter Xinjiang.

During the Tang Dynasty, the national strength was strong, and Anxi Prefecture was established in Xinjiang, with a large number of troops stationed and a certain number of immigrants settled.

In the Song Dynasty, the strength of the western and northern minorities surpassed that of the Central Plains Dynasty, and the Han people withdrew from Xinjiang again.

During the Yuan and Ming Dynasties, Xinjiang was under the control of Mongols.

After the Qing dynasty, especially after the left pacified Xinjiang, Han people settled on a large scale.
