/kloc-in 0/25, the state of Jin, which was only ten years after the founding of the People's Republic of China, destroyed the state of Liao. Two years later, it invaded the Northern Song Dynasty, taking away the Emperor Hui and Qin, and the Northern Song Dynasty also perished. Zhao Gou succeeded to the throne in Yingtianfu (now Shangqiu, Henan). In the eighth year of Shaoxing, Song Gaozong officially established Lin 'an as its capital, which was known as the Southern Song Dynasty.
Although the state of Jin went south several times, it failed to destroy the Southern Song Dynasty, and finally formed a confrontation between Song and Jin. There are several reasons why the emerging Jin State failed to unify China in one fell swoop.
The hot and humid climate in the south of the Yangtze River made Jin people extremely uncomfortable.
Yao Congwu once said: "In the12nd century, jurchen was' good at riding horses, brave, hungry and cold, not afraid of hard work'". These are the advantages of jurchen as a soldier.
The "cold tolerance" formed under the cold conditions in the north also doomed Jurchen to be unable to adapt to the hot and humid weather in the south. Not only the soldiers are difficult to adapt, but also the grain and grass are difficult to store, which makes the grain transportation unsustainable. Jin Wushu, the general of Jin State, once said helplessly: "Jiangnan is humble and humid, and it is not easy to store grain, so it is difficult to achieve anything." ("Jin Liu Shi Chuan Yu")
The natural barrier of the Yangtze River prevented the expansion of the Jin people.
The natural peril of the Yangtze River was a natural peril on the left side of the Yangtze River in the Southern Song Dynasty, which disintegrated the cavalry advantage of the Jin people. The Jin soldiers were not good at water warfare, which made the Jin people (Jin Wushu) "look at the ocean and sigh": "The Southern Army made the ship like a horse, so what can we do!"
Jianghuai area has become the second natural defense line.
There are many rivers and lakes in the Jianghuai area, so the cavalry of the Jin State who attacked from east to west in the plain wilderness could not give full play to their advantages.
The political situation in Jin State is unstable.
Jin Taizong died at the beginning of the founding of the Southern Song Dynasty. Jin Xizong was old when he ascended the throne, and ministers such as Zong Pan, Zong Jun and Chang were in charge of state affairs, with different aspirations.
At that time, Wan Yanchang defended Kaifeng and wanted Song to be a foreign aid. He argued and was later punished for rebellion. After Jin Wushu came to power, he advocated invading the south, but was defeated by Liu Yong, Wu Jun and Yue Fei successively. His morale was shaken and his morale was greatly reduced. Internal divisions have also created an uncertain situation of peace and war.
After the death of Jin Wushu, Jin Xizong wasted his time in debauchery and bloodthirsty, and the corruption of the Jin Dynasty intensified, and he was finally killed by Wan Yanliang.
Limited by Xu Jin's own strength.
Jin is a small country under Liao State, with limited national strength. Its Jurchen nationality is a nomadic people with low culture. The annexation of Liao has been digested, and there is no spare capacity to rule China.
The state of Jin had no intention of destroying the Song Dynasty, and its invasion to the south mostly depended on plundering property. They took Qin Hui's empresses away for fear of revenge from the Song people. For the south bank of the Yellow River, there is no time to take care of it. Therefore, the puppet regimes of Chu and Qi were established to deal with the Southern Song Dynasty. But Liu Yu's pseudo-qi couldn't beat Song Jun, so he had to ask Xu Jin for help, and even the nomads from the army were defeated by Song Jun.
The State of Jin realized that it was difficult to eliminate the regime in the Southern Song Dynasty. The Song emperors Gaozong and Qin Gui advocated peace talks, so the two countries made peace.
Containment of the Mongolian army
At that time, the Mongolian tribes in Mobei became more and more powerful, which had already posed a threat to the State of Jin. Jin Xizong sent troops to crusade, but he was defeated. Because of fear, the state of Jin could not fully attack the Southern Song Dynasty.
In the early years of the Southern Song Dynasty, there were many loyal, patriotic and brave generals.
In the early years of the Southern Song Dynasty, there appeared some brave generals, besides Yue Fei and Han Shizhong, there were Wu Jun, Wu Lin, Liu Yong, Zhang Jun, etc. They fought and lost many times, which revived the Southern Song Dynasty. On the other hand, Jin Guo's "old viceroy will die in the future" has a different feeling compared with the two.
1 16 1 year, Yan Hongliang, the gold owner, wanted to unify China and sent 600,000 troops to attack the Southern Song Dynasty. Although all the way to triumph, but only crossed the Huaihe River. Before he could cross the river, he was defeated in Historical Records. Since then, the state of Jin has never invaded the south on a large scale.
