Li Shimin relied on the change of Xuanwu Gate to climb to the peak of life, although the means were disgraceful, the process was also very thrilling, fortunately, "the ending is good, everything is good."
Because Li Shimin not only won the victory of the Xuanwumen Revolution, but also used his personal achievements and historical contributions in a down-to-earth manner, he was recognized and praised by future generations, and became a red man in history.
Pity: people are not much red! Li Shimin's front foot had just pressed down on the "gourd of the change of Xuanwu Gate", and the back foot had risen again to "occupy the scoop of the sister-in-law Yang Clan". So much so that some people have declared that it was because of his sister-in-law Yang Shi that Li Shimin braved the world's great disobedience and launched the Xuanwumen Revolution.
People with a little historical knowledge of this statement know that it is purely an operation of "not surprising and endless", which is not enough to believe at all! However, it can be seen from this that Li Shimin has caused himself what kind of embarrassment he has caused by occupying his sister-in-law Yang Shi. So why did Li Shimin do this?
There are many reasons, such as starting from the family background: because the Yang family is from the Hongnong Yang family, Li Shimin actually occupies not his sister-in-law, but the resources behind the family. After all, after the change of Xuanwu Gate, Li Shimin needed to appease all the forces, and the best way to face the door valve nobles was to get married, so that the Yang clan could be upgraded from a princess to an imperial princess, that's it!
There is also an analysis from the personal vendetta: because Li Yuanji wanted to kill Li Shimin several times and behaved more actively than Li Jiancheng, Li Shimin hated his brother Li Yuanji the most, and the occupation of Yang Shi (Li Yuanji's princess) was nothing more than revenge.
Of course, there are various other reasons, and these two views are the most convincing. However, the author has a question: it is known that Li Shimin and empress eldest grandson can be called the "model couple" among the emperors, and their feelings are very deep. And empress dowager, the eldest grandson, was also the famous Empress Xiande.
For example, when Li Shimin wanted to kill Wei Zheng, he was persuaded by Empress Changsun, and Li Shimin also listened to empress Dowager Changsun's advice the most. So why, when Li Shimin occupied his sister-in-law and committed such a self-destructive affair, Empress Eldest Sun did not come forward to dissuade him, and even did not react at all?
One: identity change
I'm afraid this is the easiest thing to think of. Before the change of Xuanwumen, Li Shimin was a prince, and everything he did revolved around how to become an emperor. Wasn't yang Guang the same way back then? Since marrying Xiao Hou (Xiao Meiniang), Yang Guang has always been very well-behaved, showing unusual restraint, and always showing off with Xiao Hou with the appearance of a loving husband and wife.
However, when Emperor Wen of Sui had just died on his front foot, Yang Guang took over his father's concubine that night: Lady Xuanhua. (Book of Sui: The crown prince (Yang Guang) sent an emissary to give his wife a letter of honor... The people of the palaces forced him to do so, but they worshiped the messengers. In his night, the prince was in a hurry. ）
Therefore, referring to Yang Guang's actions, it is natural to come to the conclusion that "identity change is caused". That is to say, Li Shimin was suppressed for too long, which suddenly succeeded, and he was oblivious for a while.
Empress Eldest Sun naturally understood Li Shimin's cathartic mood, so she simply played missing. Of course, self-protection factors cannot be ruled out! After all, Li Shimin became the emperor, in case he was dissuaded and could not be crowned empress, it would be because of small losses, and the gains would not be worth the losses.
Later, there are also historical sources to support this view: Empress Eldest Sun personally searched for harem beauties for Li Shimin, she selected Zheng Renji's daughter, and the dowry was given, and she was sent to the palace gate.
Wei Zheng stood up to stop it, saying that Zheng Renji's daughter had already been promised to a man named Lu Shuang. So The emperor's eldest brother, you are going to forcibly marry someone else's wife. I Wei Zheng was for the good of the emperor's eldest brother, so I had to tell the truth, to be this evil person. (Old Book of Tang: The daughter of the Zheng clan now, who has long been promised, His Majesty has taken it without an adviser, spread it all over the world, and is rumored by the righteous subjects of the parents, or not pointed out, for fear of losing virtue, do not dare to hide.) ）
After reading this historical material, I have to admit that this is the situation after the identity change - no way, since ancient times.
Second: Wei Zheng told the truth
As we all know, after the death of Empress Changsun, Li Shimin once wanted to make his sister-in-law Yang Shi empress, but was once again blocked by Wei Zheng. And Wei Zheng's original words were very ugly: His Majesty is better than Tang and Yu, why should he be tired of himself with Chen?
That is to say, the emperor's eldest brother, you have always compared yourself to the ancient sages, but why are you carried away by such a bad woman as Chenwei?
Key point: Tatsumi. She was a beautiful woman of the Qin Kingdom, first married to the Duke of Jinhuai, and after the death of the Duke of Jinhuai, she married her uncle Duke Wen of Jin and gave birth to Gongzi Le. After the death of Duke Wen of Jin, some ministers proposed that Gongzi Le be the boss of the Jin State, but Zhao Dun was resolutely opposed, believing that Chen Wei was "obscene" and that her son Was not worthy of the throne and could not be the king of the Jin State.
Obviously, Wei Zheng compared Yang Shi to Chen Wei.
This raises a question, because since the Yang clan was occupied by Li Shimin and gave birth to Li Shimin's son Li Ming, it is reasonable to say that the status should be noble, after all, li Shimin's woman. But why did Wei Zheng, as a courtier, dare to be so "no big or small" to her?
There was only one answer, that is, Yang Shi had never been able to become a concubine of Li Shimin's harem. Moreover, Li Shimin never gave her a name.
After the change of Xuanwu Gate, Li Yuanji was deposed as a Shuren, and even the Qi Palace was rewarded by Li Shimin to Wei Chigong. The Yang clan also lost her status as a princess and became a Shuren.
Later, when Li Shimin sat firmly on the throne, he posthumously named Li Yuanji the "King of Hailing County", and Yang Shi was also restored to princess of Hailing.
In the 17th year of Zhenguan, when Li Shimin posthumously awarded Li Jiancheng the title of Prince of Yin, Li Yuanji was also posthumously awarded the title of "King of the Nest, The Thorn of the Nest", which was Li Shimin's last posthumous title (gift) to Li Yuanji, and the Yang clan was eventually fixed in the "Princess of the Nest Thorn".
Therefore, Wei Zheng dared to speak so ugly. And Li Shimin could only listen with dry eyes. After all, Wei Zheng was right! Moreover, Li Shimin's desire to make Yang shi empress is also most likely the result of a hot brain.
But in any case, it is obvious from Wei Zheng's words why Empress Eldest Sun did not dissuade Li Shimin from occupying her sister-in-law Yang.
Third: Why didn't Empress Eldest Sun dissuade her?
First, Li Shimin did not marry the Yang clan into the harem at all. The empress has always presided over the harem and is the eldest sister. Under such circumstances, how could Empress Eldest Sun openly dissuade her? At most, it was just the wind on the pillow, or when there was no one to look at, viciously twisting Li Shimin's ears.
Second, Li Shimin's so-called hegemony of his sister-in-law Yang Shi most likely occurred after the death of Empress Changsun. This is also the reason why I most agree.
That is to say, after the change of Xuanwumen, Yang Shi, like Li Jiancheng's crown princess Zheng Guanyin, was imprisoned. Only later, due to the death of Empress Changsun, by chance, Li Shimin "occupied" the Yang clan.
This can also be corroborated by the birth time of Li Ming, the King of Cao.
Li Ming, the son of Li Shimin and the Yang clan, was made the King of Cao by Li Shimin, but his year of birth is unknown, only that he was named King of Cao in 647 and died in 682. First, if Li Mingzhen was born in Li Shimin's harem, how could he not have a birth time? Second, Empress Changsun died in 636 AD, and 12 years after her death, Li Mingcai was canonized.
Therefore, the author's conclusion is that it is not that Empress Changsun did not dissuade her, but that the so-called Li Shimin's occupation of her sister-in-law Yang Shi occurred after the death of Empress Changsun. Instead of what people think, not long after the xuanwumen change ended, Li Shimin began to move...
