Yin Prefecture

Yinzhou or Yin Prefecture (Chinese: Yínzhōu 銀州; Tangut: 𗷲𗉔 or 𘝰𗉔) was a zhou (prefecture) in imperial China centering on modern Hengshan County, Shaanxi, China. It existed (intermittently) from 563 to 1106. In the 10th- and 11th-centuries it was mostly controlled by the Tangut people as part of Western Xia (1038–1227) or its precursor, the Dingnan Jiedushi. In 1081 it became territory of the Song dynasty.

The administrative region of Yinzhou during the Northern Zhou is in modern Shaanxi. It probably includes parts of modern:
