"Qin Emperor Han Wu, Tang Emperor Song Zu" should be regarded as representing the highest ruling standard of ancient Chinese emperors, among them, Tang Taizong Li Shimin should be a highly respected emperor, as the son of Tang Gaozu Li Yuan, he helped his father establish the Tang Dynasty, and later was named the King of Qin, and inherited Li Yuan's throne.
There are many things worth singing in Li Shimin's life, and the biggest thing is to create the rule of Zhenguan, which pushed the prosperity of ancient China to a peak, and also laid the foundation for Wu Zetian's Zhenguan legacy and Li Longji's Kaiyuan prosperity.
Of course, everyone has shortcomings, or a disgraceful side, and the emperors of "Qin Emperor Han Wu and Tang Zong Song Zu" also have their own black history.
Li Shimin's biggest black history is to launch the Xuanwumen Rebellion, killing his brother to force his father, usurping the throne, the xuanwumen change has always been very controversial, in this coup, Li Shimin killed his brother Li Jiancheng, the younger brother Li Yuanji, the Prince of Qi, and even persecuted Li Yuan, and finally let Li Yuan give up the throne.
So the question is, since Li Shimin killed his brother and killed his father, why did he occupy Li Jiancheng's wife instead of killing Li Yuan? Marrying his sister-in-law should be said to be a thing that is inferior to animals, and since it is inferior to animals, why not kill his father together?
Why did Li Shimin want to seize the wife of Prince Li Jiancheng?
In fact, everything Li Shimin does is a deliberate process, many people think that Li Shimin covets beauty, so he occupies his sister-in-law, which is inappropriate, in Li Shimin's position, it is impossible to lack beautiful women, especially such second-hand goods, what he does, more political considerations.
Li Jiancheng's crown princess Zheng Shi looks good or not, we don't know, but the origin of the family is quite good, Xingyang Zheng clan originated from the Zheng kingdom of Zhou Xuan, although the royal family later ceased to exist, but still use the Zheng surname as their surname.
From the end of the Eastern Han Dynasty to the middle of the Tang Dynasty, what played a great role in marriage was the family background, and people regarded the origin of the family as very important, especially after the Wei and Jin Dynasties, everyone hoped that the prominence of their family could be passed on, so they intermarried with the prominent family.
After entering the Tang Dynasty, the family surnamed Zheng was still a famous and prestigious family, very prominent, and in the Tang Dynasty there was a famous five major surnames, which were: Cui, Lu, Li, Zheng, and Wang. What was popular at the time was intermarriage between the five major families.
People with foreign surnames who want to climb relatives are usually excluded from the five major families and are not allowed to intermarry with them.
At that time, the trend of intermarriage was becoming more and more prosperous, and even Wei Zheng and Fang Xuanling were very hopeful that they could intermarry with the five major families. Generally speaking, Wei Zheng and Fang Xuanling were more prominent in the Tang Dynasty, but those rich and prestigious families were still unmoved. Of course, the royal family is also a flesh and blood person, and also wants to intermarry with them.
In the "New Book of Tang And Du Jian Biography", it is recorded that by the time of Emperor Wenzong of Tang, he also complained: "The folk practiced marriages and read them without counting official goods." My family's two-hundred-year-old son, can't care about Cui and Luye? ”
Because of this, even if the princess is a second-hand commodity, Li Shimin is not abandoned, the main focus is on the background of the Xingyang Zheng clan, the political purpose of the Xingyang Zheng clan marrying women to Li Jiancheng is to maintain the relationship between the Hao clan and the imperial family, if Li Shimin kills the crown princess in the Xuanwumen change, that point provokes the dissatisfaction of the Xingyang Zheng clan.
For Li Shimin at that time, one more enemy was better than one less enemy, and uniting all people who could unite was the king! From a custom point of view, the Li Tang Dynasty originated from the Guanlong clique, and there was a great connection with the ethnic minorities in the Northern Dynasty period, at that time, the Confucian set of things had not yet flourished, marrying a sister-in-law this kind of thing is simply a common small scene, this can not be accepted, then how do you accept that Later Li Zhi married his stepmother Wu Zetian, Li Longji married his daughter-in-law Yang Yuhuan These things!
Why didn't Li Shimin directly kill Li Yuan during the Xuanwumen Revolution?
The change of Xuanwumen in everyone's impression is a mutiny in which Li Shimin, the prince of Qin, and Li Jiancheng, the crown prince, compete for their position. He ambushed the ambushers inside the Xuanwu Gate and killed the crown prince Li Jiancheng and the Qi king Li Yuanji. He also asked Wei Chigong to enter the palace to warn Li Yuan. Then some people will not understand, since they have already killed their brother and brother, why not directly kill Li Yuan, and then Li Shimin directly ascended the throne as emperor.
One reason is that Li Yuan is Li Shimin's father after all, and at this time Li Jiancheng and Li Yuanji were killed by Li Shimin, and it was because they both threatened Li Shimin's position. But after they died, the whole situation was controlled by Li Shimin, at this time Li Yuan had no other choice, and the only person who could pass the throne was Li Shimin, so Li Shimin could get the throne without killing Li Yuan.
Moreover, he killed Li Jiancheng and Li Yuanji, and it can be said that the two of them tried to rebel, and Li Shimin sent troops to suppress them. Since people are dead, how to explain it all lies in Li Shimin to preserve his reputation.
Moreover, killing his father and killing the king is a great rebellious act, if Li Shimin wants to have a better impression of the new emperor after he ascends the throne, he must make the behavior of Ming Jun, although he has killed his brother and brother, but fortunately, there is still Li Yuan, and at this time he can show the image of his filial piety. It can stabilize the situation in the DPRK very well and is conducive to holding political power on its own.
The actual conflict between the Xuanwumen change itself is actually Li Yuan and Li Shimin, and Li Jiancheng actually represents Li Yuan.
Li Shimin's power before the change of Xuanwumen was very strong, so Li Jiancheng would suppress it, and although the timing of the change of Xuanwumen was accidental, Li Shimin was indeed prepared, and it can also be said that this was a natural success.
Li Shimin must have considered in detail before the change of Xuanwu Gate, what kind of choice Li Yuan would make, there must also be Plan B, in other words, if Li Yuan decided on the fact of inheritance, then everything was negotiable and good for both sides; if Li Yuan did not cooperate, then Wei Chigong was not a fuel-saving lamp, and it was not certain that Li Yuan would chop Li Yuan with a knife in his hand.
In fact, Li Shimin asked Wei Chigong to warn Li Yuan that Wei Chigong's clothes were already splashed with the blood of Li Jiancheng and Li Yuanji, which was actually to scare Li Yuan, whether to admit reality or to break the net, for any father, he would admit the established reality.
In the end, Li Shimin reasonably inherited the throne as he wished, and it can be said that in every link of the change of Xuanwumen, Li Shimin was designed just right. Of course, Li Shimin's approach can be said to have set a bad precedent for the Tang Dynasty, and since then, the Tang Dynasty's coup has not been interrupted.
