Why did the Yuan Dynasty exterminate the Jin Dynasty royal family, but treated the Southern Song Dynasty royal family with courtesy?

Why did the Yuan Dynasty exterminate the Jin Dynasty royal family, but treated the Southern Song Dynasty royal family with courtesy?

In 1233, the Mongols who rose up in the north occupied the capital of the Jin Dynasty, Fenjing, frightening the Jin Emperor Jin Aizong and immediately fleeing to Caizhou.

Although it is said that the Jin Dynasty can be destroyed by mongolia's own strength, casualties are certainly inevitable, so the Mongols found the Southern Song Dynasty and said that they could unite with the Southern Song Dynasty and destroy the Jin Dynasty together.

From the beginning, the Southern Song Dynasty regarded the Jin Dynasty as an enemy of life and death. At this time, it was hard to have a chance to be humiliated, and the Southern Song Dynasty was too late to be happy, and immediately sent a large army to surround Caizhou. Ping-Pong ping-pong was played for more than a year, the city of Caizhou was destroyed, Jin Aizong and The Late Jin Emperor were killed, and the Jin Dynasty was destroyed.

In fact, as early as when the Mongols conquered the city of Kaifeng, Wokoutai Khan issued a Daoist order, "Except for the Yan clan, all the remainder are exempt." To put it bluntly, it is to exterminate the Royal Family of the Jin Dynasty.

After the fall of the Jin Dynasty, the Southern Song Dynasty bordered Mongolia. Sure enough, the year after the fall of the Jin Dynasty, the Mongols sent troops to attack the Southern Song Dynasty. The war lasted until 1279, and the Southern Song Dynasty, which was ridiculed by later generations, resisted the Mongol iron horse for decades.

Compared with the Jin Dynasty, the Southern Song Dynasty royal family seemed to be full of luck. Not only did he save his own life, but he was also treated with courtesy by Kublai Khan, the ancestor of the Yuan Dynasty. The gap between before and after is so huge that one can't help but wonder if there is any secret between them.

Of course, there should be no secrets, but the reason why the Mongols will exterminate the Jin Dynasty and treat the Southern Song Dynasty with courtesy, I think it is for these reasons.

1, the Jin Dynasty has been oppressing and exploiting Mongolia, and is extremely cruel to the various means of Mongolia

For the Jin Dynasty, the Mongols were a slave tribe. All along, the Jin Dynasty has implemented a policy of national oppression against Mongolia, and as long as Mongolia has any good things, the Jin Dynasty will immediately send people to grab it.

This was all a trivial matter, and during the time of Emperor Jin Xizong, Genghis Khan's ancestor, Baba Bao Khan, obviously did nothing and was executed on the charge of rebellion. By the time of Kim Sejong, it was enough to increase taxes on Mongolia, and every three years he had to send troops to Mongolia to kill people, so-called reduction, so as to reduce the threat of Mongolia.

It can be said that mongolia and the Jin Dynasty were feuds, and there was a deep grudge between the two sides. The hard rise of Mongolia can destroy the Jin Dynasty, and the losses suffered at the hands of the Jin Dynasty must be repaid twice.

And the Southern Song Dynasty, because it was partial to the south, had no contact with Mongolia at all, and could not bully Mongolia if it wanted to, so there was no hatred.

2, nomads are not easy to manage

The Jin Dynasty was a Jurchen people, this is a nomadic people, has always been a fierce and disobedient discipline, if not exterminated, with the strong survival ability of the nomads, sooner or later it will pose a threat to Mongolia.

For example, after the Liao, after the Jin Dynasty destroyed the Liao, it was because the Jin Dynasty did not kill them all, which allowed the descendants of the Liao State to run to the west to establish the Western Liao. With this lesson in the past, Mongolia naturally has to learn a lesson.

The Southern Song Dynasty was different. The Southern Song Dynasty was dominated by Han Chinese and had an advanced civilization, which could be well controlled as long as the methods were proper.

3, the Mongolian boss of the two periods is not the same person

When the Mongols destroyed the Gold, the boss at that time was Wokoutai Khan. This is a guy who likes to slaughter the city, and even he has set a rule, saying, "Whoever attacks the city, one by one in the city will shoot stones, and if he disobeys the throne, he will slaughter it."

Under the guidance of this kind of thinking, it is strange that the Royal Family of the Jin Dynasty was not driven to extinction.

By the time the Southern Song Dynasty was destroyed, the Mongol boss had become Kublai Khan. During kublai Khan's time, the Mongols continued to deepen feudalization and Sinicization, no longer as barbaric as in the time of Wokoutai Khan, so the policy of killing was also despised.
