After the demise of Liao, Jin rose slowly and became the strongest regime in the north. In the Northern Song Dynasty, he was often bullied by the State of Jin. Later, the State of Jin went all the way south, even taking Song Huizong and Song Qinzong, which was called "the shame of Jingkang" in history. After the demise of the Northern Song Dynasty, the State of Jin occupied the north of the Yangtze River and became the ruler of the Central Plains. In the Southern Song Dynasty, it could only live in the south of the Yangtze River.
Although Jin destroyed the Northern Song Dynasty, the history is always strikingly similar. Just a few decades after the rise of Jin Guo, Mongolia in the north also rose, and Genghis Khan, the god of war, appeared. Under Temujin's leadership, Mongolia has risen rapidly, and Mongolians are as strong as jurchen. After Genghis Khan unified Mongolia, he broke off diplomatic relations with the State of Jin, forced Xixia to surrender, and later joined hands with the Southern Song Dynasty to destroy the gold.
The war between Mongolia and the State of Jin lasted for 24 years. Actually, the last four years are the key. From 1 12 1, Mongolian troops attacked the capital of Jin State three times, even the emperor Hong Yan Yongji was killed, and Jin State was forced to move the capital. This is exactly the same as when Jin destroyed the Northern Song Dynasty. It was the reincarnation of heaven, and the retribution was not good.
Genghis Khan attacked the capital of Jin (now Beijing) three times. For the first time, he plundered a lot of treasures, women, cattle and sheep. The second time, Jin Xuanzong surrendered directly and let Genghis Khan choose many beautiful women. That's how Qi Country Princess was taken. The third attack of the Mongols on Zhongdu occurred in 12 15. At that time, the capital of Jin State had moved. After Genghis Khan broke the city, he ordered all his belongings to be taken away.
It stands to reason that Zhongdu at this time has become the territory of the Mongolian army. Genghis Khan is a visionary. Of course, he knows that cities and population are the fundamental elements of national development. But after he robbed Zhongdu, why did he order it to be burned? You know, Zhongdu was one of the most prosperous cities in the north at that time.
At the end of the Qin Dynasty, Xiang Yu entered Xianyang City and also burned Epang Palace, but he regretted it after burning it. Someone advised him to stay in Xianyang, but Xiang Yu said that he didn't go home to show off until he saw the scenery. Isn't it a night tour? Unexpectedly, Genghis Khan did the same thing as Xiang Yu. Why did Genghis Khan do this?
It turns out that the battlefield between Mongolia and Xu Jinguo has a long history. As early as Genghis Khan's great-grandfather period, why did Mongolia have a good relationship with Xu Jinguo? He was always polite to Xu Jinguo and was attacked every year. Later, his son (Genghis Khan's grandfather) personally sent a beautiful woman to Jin Xizong, only to be arrested in Xu Jinguo and crucified on a donkey. Genghis Khan has always remembered this hatred.
So Genghis Khan wanted to destroy the State of Jin, leaving no legacy. The Mongolian empire has always done this. Later, Genghis Khan was killed by Princess Xixia, and his descendants were wiped out by Xixia. This is the consistent style of Mongols.
