Yòu Prefecture

Youzhou or You Prefecture (宥州) was a zhou (prefecture) in imperial China in modern southern Inner Mongolia, China. It existed (intermittently) from 738 to early 13th century, when the Mongolian Yuan dynasty destroyed Western Xia (1038–1227). In the 9th-century it was briefly occupied by the Tibetan Empire. In the 10th-, 11th and 12th-centuries it was mostly controlled by the Tangut people as part of Western Xia or its precursor, the Dingnan Jiedushi.
