/kloc-At the beginning of the 3rd century, Mongolia rose in Mobei. Genghis Khan began to expand outward while unifying the Mongolian grassland. In the 12th year of Tianqing (1205), Mongolians invaded Xixia, plundered human and animal property, and lost ground. During the Tianyuan period (1206), Li Anquan deposed Huanzong and established himself as emperor, that is, Xiangzong of Xixia. This autumn, the Mongolian army invaded Xia again. In Yingtian four years (1209), Genghis Khan invaded Xia for the third time and Xixia was defeated. The Mongolian army entered Zhongxing House (1205, after the retreat of the Mongolian army, Xia Huanzong changed the capital Xingqing House to Zhongxing House), leading the Yellow River to flood the city. The city will break and the outer dike will collapse. It is also difficult for the Mongolian army to stay at the foot of the mountain and clear the field by itself. Xiang Zongna's daughter, please surrender, surrender Mongolia and attack Liao country. In the first year of Guangding (12 1 1), Li Zunxu, the king of the imperial clan, abolished Xiang Zong as emperor and became the emperor of Xixia.

Six years later, Genghis Khan began to assemble troops for an expedition to Central Asia and recruited soldiers from Xixia many times. Summer was unbearable and he refused. In seven years, the Mongolian army invaded Xixia for the fourth time, and Zhongxing House in Tokyo was besieged. Zongshen fled to xiping county, Xijing, and Prince Li Deren defended the capital, once again demanding that Mongolia surrender. Zongshen tried to unite Jin against Mongolia, but was rejected by the State of Jin, and tried to unite the Southern Song Dynasty to attack Jin. In the 13th year of Guangding, Prince Li Deren of Shinto led troops to invade Jin. Li Deren advocated joint payment and refused to accept the order. Abolish virtue, that is, the throne is passed to the second son Li (Xixia Xianzong), claiming to be the emperor's father. After Li succeeded to the throne, there was a dispute with Mongolia. In the second year (1224), the Mongols attacked Yinzhou, and Xia Jun suffered heavy losses. It also sent a special envoy to make peace with Kim and agreed to be a brotherly country to protect itself.

In the fourth year (1226), Genghis Khan led an army to attack the summer, and the soldiers were divided into two ways: all the way to capture Sha, Su, Gan and other States, reaching Xiliangfu (namely Xijing, namely Lingzhou); The other route starts from xiping county, starts with Genghis Khan and enters Helan Mountain.

In July, Xiliangfu fell, and Xixia died in mourning, and his nephew Li (the late emperor of Xixia). 1 1 month, after the Mongolian army captured Lingzhou, it entered Zhongxing House. Zhongxing mansion was besieged, and food was saved. The last emperor sent a special envoy to seek surrender. In the second year of Baoyi (1227), in July, the Mongolian army captured Zhongxing House and Xixia perished.
