Lingwu

Lingwu is the most important industrial city of the Ningxia Hui Autonomous Region, in the northwestern region of the People's Republic of China. It is under the jurisdiction of Yinchuan, the Region's capital city. Lingwu's former name is Lingzhou. During the Tang Dynasty, Emperor Suzong of Tang (711–762) fled to Lingzhou during the Anshi Rebellion, where he formally ascended the throne. Later on, Lingzhou became part of the Western Xia (Tangut Empire, 1032-1227). It was laid siege by Genghis Khan in November 1226.
