The capital of the Western Xia kingdom conquered by Genghis Khan was Zhongxing. The city stood in the area of modern Yinchuan in Ningxia, north-central China, and served as the political center of the Tangut-led Western Xia state.
The city’s name changed over time, which explains a common source of confusion. It was known as Xingqing during much of the Western Xia period and as Zhongxing from 1205. Both names can therefore appear in historical references, but Zhongxing is the name associated with the capital during the final Mongol conquest.
Genghis Khan first attacked Western Xia in the early 1200s and returned for a final campaign in 1226. The Mongols captured key cities, defeated relief forces, and reached Zhongxing in 1227. The capital resisted for months, while Mongol forces also conducted operations against the Jin dynasty to prevent assistance.
After the city surrendered in September 1227, Western Xia was destroyed as an independent kingdom. Genghis Khan died during this final campaign, though the exact circumstances remain uncertain.
