The First War: In the fifth year of Ren Zongjing in the Northern Song Dynasty, Li Yuanhao, the leader of the Tangut regime in the Song Dynasty, broke away from the Song Dynasty and claimed to be the emperor. In the Song Dynasty, he became the national title, and changed the national title of the Yuan Dynasty into an extension of God-given etiquette. The founding of the country and the founding of the country to the hero were called Xixia in history. In the second year of Song Renzong, Jing Zong Li Yuanhao of Xixia wrote to the Song government, hoping that they would admit this fact. However, most officials in the Song Dynasty advocated sending troops to attack Xixia immediately. So in June of that year, Song Renzong wrote a letter to Hao Yuan offering a reward for his capture. Since then, the Song-Xia War, which lasted for three years, broke out in an all-round way. During the Northern Song Dynasty, there were three large-scale battles with Xixia: Sanchuankou, Haoshuichuan and Dingchuan, all of which ended in Song Jun's defeat. Although Xixia won many victories, the plunder had to offset the consumption in the war. Compared with the previous materials according to the peace treaty, it is not worth the loss through the transaction between Song and Xia people. In addition, due to various subjective reasons, such as Jing Zong Yuan Hao Xiahou _ exultation in Xixia, he fought everywhere, the national treasury was empty, non-governmental trade was interrupted, Xixia currency rose, and the people were in poverty and complained. There were many contradictions between Xixia and Liao, which forced Xixia to negotiate with Song Dynasty. So, in June, Yuan Hao sent Li Wengui, the royal family of Xixia, to discuss in the capital of Tokyo. In the second year, the two sides began formal negotiations.

Later, in World War II, in the first year of Zhiping, the Xixia Raiders Gyeongju was defeated by Song Jun in Dashun City, and Emperor Wu of Song died of injury more than a year later. After Xixia, it was gradually on the defensive. During the reign of He and Xia, a large-scale war broke out between Song and Xia.

The third war, the battle of Xihe

In November of the 4th year of Yuan Dynasty, Wang Shao defeated Xia Jun in Qingzhou and occupied more than 2,000 miles of Xixia land. In the battle of Yongle City, in September of the fifth year of Yuanfeng, the general and Tao Zi planned to attack the summer and prepare to destroy it in one fell swoop. Xu Xi and others invaded Hengshan area of Xixia, which matched Xingqing House, the capital of Xixia. In order to destroy the summer, people built Yongle City on the Yongle River. Xixia sent six supervisors of 300,000 troops to unify the army to attack Yongle City. Xu Xi didn't refuse to listen to his subordinate Gao Yongheng. Surprise is the right strategy, but he arranged 10 thousand soldiers at the gate. After crossing the river, Xia Jun stormed Song Jun, Song Jun was defeated and retreated into the city. Xia Junbing encircled Yongle City and cut off the water flow in the city; And Shen Kuo eunuch Li Xian's reinforcements were also blocked. Because of resentment against Xu Xi, the seeds were not preserved. Xia Jun finally breached Yongle City, Xu Xi and others were killed, and more than 200,000 soldiers and servants in Song Jun were killed.

The fourth battle, the battle of Rudolf scharping.

In the third year of Shaosheng, Song Jun conquered Hongzhou, Yanzhou, Youzhou, Pingxiacheng, Huizhou and Qingtang in Xixia. The situation in Xixia was declining, so he had to send envoys to the Song Dynasty for peace.

1096 10 In the winter, Liang Xiao, queen of Xixia, and Li Ganshun, emperor of Xia Chongzong, led an army, claiming to be 500,000 troops, and attacked Song Road. However, all the counties were well protected, so Xia Jun had to attack Jinming Village and leave Qi Jing near Long 'an Village. Xia Chongzong's mother and son visited the front array and beat drums. The soldiers of Xixia army were in high morale, and they poured into Jin Ming village. Changyu and the garrison commander's 2,500 people in Song Jun were almost slaughtered. Only five people thought of flying and seized a lot of supplies. After taking Xixia, he told Song that the imperial court was not friendly to me. Originally, I was going to attack Yan Yan, but because of respect, I only brought Jin Ming, so I didn't lose my ministerial day. When he heard of the summer invasion, he accepted it calmly. 500 thousand people went deep into our territory and captured one or two stockades in ten days at most. Later, the war as Song Zhezong expected. Later, Zhang Ji of Zhi Zhi Prefecture suggested imposing economic sanctions on Xixia in order to crack down on the bunker. In order to practice this strategy, he established two cities in Haoshui River at the mouth of Shimen Xiajiang River, named Xiaping City and Heping Village respectively. In the second year, Song Jun launched military revenge and conquered Hongzhou, Youzhou, Huizhou and Qingtang in Xixia. Zhang Cun once occupied Yanzhou, but on his way back to Li, he was chased and set on fire by the Xixia army and was attacked on all sides. Zhao and others were killed by officials, Yanzhou fell, but Xixia was revenged by the former power.

With the construction of the city, the passage of Xixia army attacking Song was blocked. So, in 1098, Empress Liang Xiao and Li Ganshun of Xia Chongzong stormed Xiaping City again, but the Xixia army was crushed by heavy snow and finally suffered a fiasco. Zhang Yi sent his troops, and Guo Cheng rode lightly all night, capturing the Xixia generals Amitabha, Lemeiduji and their people. History is called the Battle of Sharpin City. After the news of victory came out, Song Zhezong personally went to Chenzi Temple to accept the congratulations of the minister and was awarded a bachelor's degree. Received a doctor's degree and an advanced doctor's degree in Longtugeming Temple. Later, Song Jun built Xi 'an Temple and Tianduzhai, opened Jingyuan Road and Xihe Road, and controlled most areas of Hengshan Mountain. After that, Qin Zhou became inland, and Song Jun gained a strategic advantage over Xixia. After the song dynasty controlled Hengshan area, Xixia's situation became increasingly difficult. 1099, a coup took place in Xixia. With the secret help of Liao, the Queen Mother was poisoned. Then Xixia, on the grounds of the death of the Empress Dowager, sent envoys to make love in Song State and paid tribute to Yan in middle school, which was an apology. Song said that he would not accept the envoys of Xixia. But Liao immediately sent Privy Council official Xiao Dechong to mediate between Song and Xia. Finally, Song had to accept the peace of Xixia.

The fifth world war, the battle of Hengshan

In the fourth year of Zheng He, Song Jun, under the leadership of Tong Guan and Zhong Shidao, defeated the Xixia Army in Gugulong, and conquered the land of Mount Heng in Xixia in the first year of Xuanhe. Xixia lost its barrier, and the Xixia Sect surrendered to the Song Dynasty. In the second year of Kang, the Northern Song Dynasty was destroyed by the Jin Dynasty.
