The Kelie department in Mobei was very friendly with Xixia, but later the Mongolian department annexed many tribes under the leadership of Temujin. 1203 Kelie Department was annexed by Temujin, and Sang Kun, the son of its leader Wang Han, fled to Xixia. Two years later, Temujin led an army to invade Xixia and plundered the border cities of Xixia. Xia Huanzong thought that repelling foreign invasion and renaming Xingqing House as Zhongxing House meant that Xia Guo was reviving. In fact, Xixia was threatened by Mongolia. 1206, Temujin established Great Mongolia, namely Genghis Khan, and was later honored as Yuan Taizu. Genghis Khan had to cut off the Jin-Xia alliance in order to destroy the enemy Jin Dynasty, so Xixia became one of his goals. In the second year, shortly after Xia Xiangzong came to power, Genghis Khan led an army to break the Xixia fortress-Wolong Haicheng (now the western border of Urad Houqi, Inner Mongolia), which was repelled by Xia Jun's strenuous resistance. 1209, Mongolia surrendered to Gaochang Uighur, and Hexi area was also exposed to the threat of Mongolia. In the summer of the third year, Mongolia invaded from Hexi, left Heishui City and besieged Woluo Customs. Chengzhen Li, the son of Xiaxiangjiao, led the army to resist and failed. Xia was captured by foreigners and died. The Mongols also captured Woluohai City, which was wrongly guarded at the Western Wall, and forced back the last line of defense of Zhongxing House-Keyimen. Xia Jiang led an army to ambush the Mongolian army and was finally defeated by the Mongolian army. Zhongxing Mansion was besieged by Mongols, and the sectarian emissaries from Xia Xiang turned to Hong Yan Yongji of Di Chin for help, but Di Chin refused and took pleasure in attacking neighboring countries. In the end, Xia Xiangzong accepted women's invitation for peace and contributed a lot of materials, and attached Mongolian [8].
After Xia Xiangzong was attached to Meng Fajin, he fought a war with the rulers for more than ten years, and both sides suffered huge losses. At home, the Xixia people were very poor, their economic production was destroyed, their troops were weak and their politics were corrupt. Xia Xiangzong himself indulged in debauchery all day and was indifferent to state affairs. 12 1 1 year, Li Zunxu, king of Qi, staged a palace coup, deposing Xia Xiangzong as emperor, that is, Xia Zongshen, who was called the number one emperor in history books [9]. Despite the opposition of domestic ministers, Xia still insisted on attaching Mongolia to resist gold, and Jin Xuanzong also fought back many times. At this time, the domestic social economy of Xixia was depressed and the people rebelled constantly. 12 16 because Xixia refused to help Genghis Khan to explore the west, Genghis Khan led the army to attack Xixia for the fourth time the following year. Emperor Xia and Prince Li Shou-chung started the government and fled to Xijing Lingzhou by themselves. Finally, Li sent a special envoy to Mongolia for peace talks before the final decisive battle. 1223, because Xia did not want to be the king of national subjugation, he gave way to Prince Li, that is, Xia Xianzong. At this time, Xia Ting had realized that Mongolia would perish Xixia, and Xia Xianzong decided to adopt the strategy of uniting gold to resist Mongolia. When Genghis Khan went west, he sent people to form an alliance with mobei tribes to resist Mongolia, so as to consolidate the northern part of Xixia. At that time, the Mongolian general Bolu (son of Muqali), who was in charge of the Han Dynasty, perceived Xixia's intention. On 1224, he led an army to attack Xixia from the east, capture Yinzhou and capture Tahai in the summer. In the second year, Genghis Khan returned home successfully and led the army to attack the sandbar. Finally, Xia Xianzong agreed to the conditional surrender of the Mongolian army and Mongolia's withdrawal [8]. 1226, Genghis Khan attacked Xixia from east to west on the grounds that Xia Xianzong failed to fulfill the contract, which was a battle for Mongolia to destroy Xixia. Genghis Khan led the main force to Wula Haicheng (west of Urad Houqi, Inner Mongolia), marched westward to capture Heishui City, then detoured into Helan Mountain (northwest of Yinchuan, Ningxia), defeated Xia General Asha, and finally sent troops to Hunchui Mountain (north of Jiuquan, Gansu). Led by Zuli, the marked army, together with Tudu timur, Xixia generals Xili Bell Department, Chahan and others, passed through Xizhou Uighur and successively captured Shazhou, Suzhou and Ganzhou. However, when Ganzhou was besieged, it was stubbornly resisted by garrison commander He Dian. Finally, Genghis Khan personally surrendered to the commander of Liangzhou garrison, Wozhazai. At this point, all the Hexi Corridor fell. Xia Xianzong died of anxiety, and his nephew Li Huan, later Emperor Xia, succeeded to the throne. In August of the same year, Genghis Khan led an army through Shatuo, marched into the nine capitals of the Yellow River and captured Yingli (now Ningxia Zhongwei). Then an adventurous captured Zhou Xia, surrounded by the main spirit state. At the end of summer, the emperor sent a famous soldier, Qi Huangong, to lead an army to rescue him, and the two sides fought a decisive battle on the frozen Yellow River. Later, the famous duke met the abandoned Prince Li Deren and was finally trapped and killed. The Mongols surrounded Zhongxing House, divided their troops south to capture the Xixia territories such as Jishizhou (now Xunhua, Qinghai) and Xining (now Xining, Qinghai), and entered Liupanshan in summer. There is only Zhongxing House left in Xixia. 1227 At the end of summer, the emperor surrendered to Mongolia after being besieged in Zhongxing House for half a year, and Xixia died. Genghis Khan died in Liupanshan at this time, but he didn't send out obituary, lest Xixia blame himself. Tuo Lei killed Li Wei according to Genghis Khan's will. After the fall of the Mongols, Zhongxingfu was massacred, and the palaces and cemeteries were set on fire, but it was stopped by Cha Khan, but the population in the city was not large [7][ 10]. 1227, Li Huan surrendered to Mongolia, and Xixia finally fell. Mongolian soldiers also dug three feet near the tomb of Xixia, all of which were destroyed, so that since the Ming Dynasty, they did not get too many valuable items near the tomb of Xixia. After Genghis Khan's death, there was no funeral order for fear that Xixia would go back on its word. After Li Yi surrendered, he was killed according to Genghis Khan's will. Chahan, the general of Mongolian army, tried his best to make Yinchuan avoid the fate of the massacre and enter the city to appease the soldiers and civilians in the city. The soldiers and civilians in the city were preserved, and [1 1] Xixia perished. 1288, Kublai Khan of Yuan Shizu changed Zhongxing House to Ningxia Road in the 25th year of Yuan Dynasty, and Ningxia was peaceful in midsummer! This name has been used to this day.
Li Bian, whose date of birth and death is unknown, is the grandson of Emperor Li Zunxu of Xixia, the nephew of Li, the son of the king of Qingping County, and later the king of Nanping. In July of the fourth year (1226), Li died of illness. In the same month, the imperial clan of Xixia made him succeed to the throne and changed the title to "Baoyi".
After Li Yi succeeded to the throne, he immediately sent messengers to the rulers to express his condolences in order to gain their support. Kim sent messengers to mourn and send back the population plundered in previous wars. When Li Yi ascended the throne, he was in danger of national subjugation. After taking over, he led the soldiers and civilians in the final struggle to resist Mongolia and save the country, but he could not resist the fierce attack of Genghis Khan. In the spring of A.D. 1227, Mongolian troops invaded the capital, Zhongxing House. Half a year later, due to the exhaustion of food in the city, a large number of soldiers and civilians fell ill and suffered a strong earthquake, all the palaces in the city collapsed, so we had to offer the ancestral golden Buddha and gold and silver treasures to Genghis Khan in June of the lunar calendar, asking for a grace period of 1 month before offering them to the city. Shortly after Kun Li asked the Mongols to surrender, in July of the lunar calendar, after Genghis Khan's death, there was no funeral order for fear that Xixia would go back on its word. After Li Yi surrendered, he was killed according to Genghis Khan's will. Chahan, the general of Mongolian army, worked hard to make Yinchuan avoid the fate of the massacre and entered the city to appease the soldiers and civilians in the city. The soldiers and civilians in the city were preserved, and [1] Xixia perished.
