On the fourth day of June in the ninth year of Tang Gaozu Li Yuanwude,the contradiction between Li Shimin the Prince of Qin and the prince Jianqi Wang Yuanji developed from irreconcilable to not sharing the heavens, and the fuse of the change of Xuanwu Gate was actually ignited by Li Yuan, the son of the Tang Dynasty at that time: "In June, I have not yet (the third day of the first year), and taibai has returned to heaven." Fu Yimi played: "Taibai sees Qin, and the King of Qin should have the world." 'The Lord conferred on the people of the world in his form. So Shimin Mi was built, Yuan Ji and Yin Defei and Zhang Jieyu rebelled in the harem, went to the province, were stunned, and reported: "Ming Dang Feng asked, Ru Yi early ginseng." 'Zizhi Tongjian Vol. 191 Tang Ji VII Gaozu Shenyao Great Saint Guangxiao Emperor"
The story of the Fish Belly Danshu and the Bonfire Fox Song is familiar to all the readers, the Han Gao ancestor Liu Bang slashed the snake uprising, and the red pig fell from the sky before the birth of Emperor Wu of Han, this set of tricks has been played by the emperors of all dynasties. Before Li Shimin launched the Xuanwumen Revolution, Venus operated according to its own trajectory, and it was actually said that Li Shimin should be an emperor.
The materialist view of "life and death, due to nature", Taishi Ling Fu Yi, who was proficient in the astronomical calendar and compiled the "New Law of Missed Engraving", fooled Li Yuan with the "vision" that he did not believe in, whether it was his own initiative or Li Shimin's instructions, this matter has been impossible to investigate, but one thing is certain, the day after "Taibai saw Qin Fen", there was a tragedy of brotherhood at XuanwuMen: Jiancheng Yuanji and each of his five sons, no matter how big or small, were all beheaded by Li Shimin.
The participants on Li Shimin's side of Xuanwumen's change, but two different records appear in the same Old Book of Tang. The Book of Taizong says that both Cheng Andijin and Li Shimin went to Xuanwu Gate: "In the ninth year, crown prince Jiancheng and King Yuanji of Qi plotted to kill Emperor Taizong. On June 4, Emperor Taizong led Sun Wuji, Wei Chi Jingde, Fang Xuanling, Du Ruhan, Yu Wenshihe, Gao Shilian, Hou Junji, Cheng Zhijie, Qin Shubao, Duan Zhixuan, Qu Tutong, and Zhang Shigui equal to Xuanwu Men Jiezhi. ”
The Old Book of Tang, Liechuan No. 15, has another way of saying: "On June 4, Wu Ji, Together with Wei Chi Jingde, Hou Junji, Zhang Gongjin, Liu Shili, Gongsun Wuda, DuGu Yanyun, Du Junqiu, Zheng Rentai, and Li Mengxian, nine other people, entered the Xuanwu Gate to discuss Jiancheng, Yuanji, and Pingzhi. ”
Li Shimin's revision of historical materials was not carried out thoroughly, which left a contradictory record, and Qu Tutong was already seventy years old at the time, and Fang Xuanling Du Ruqian was a pure literati, and he could not help but add to the chaos when he went to XuanwuMen. As for whether Qin Qiong and Cheng Yaojin were involved and where they were at that time, historians are still debating.
These two contradictory records in the Old Book of Tang, which one is true and which one is false, the readers have their own public opinions, but there is a question that must be made clear: Prince Jiancheng is the crown prince and the legitimate heir to the throne, is it necessary for him to launch a pre-emptive attack on Li Shimin? If Jianyuan Ji had been planning for a long time, how could he have been wrapped in dumplings in a hurry?
If we look closely at the Two Tang Dynasties and the Zizhi Tongjian and other relevant historical materials, we will find that Prince Jiancheng made at least three mistakes, and it was these three mistakes that led to his defeat in the Xuanwumen Revolution.
The first mistake That Li Shimin made was to find the wrong ally, the Qi King Yuanji's true intention, but not only to kill the second brother Li Shimin, he wanted to compete with the clams for fishing and gaining profits: "The protector Xue Bao combined the characters of Yuanji, and his text became 'Tang', and Yuanji Xi said: 'But in addition to the King of Qin, take the Eastern Palace as a reverse palm ear!'" (New Book of Tang, Liechuan 4, the same below)"
Li Yuanji constantly stirred up discord between Jiancheng and Shimin, and he concealed jiancheng's assassination of the people of the world, making it clear that he wanted to blame people: "Yuanji is a strong man who hides his life, and gives it generously and uses it." The King of Qin tasted from Emperor XingYuan Jidi, and the protector Yu Wenbao's bedchamber, and he would stab the king, the crown prince, and Yuan Ji said: "For the sake of brother, what harm to me?" ’”
Li Yuanji's move was cruel enough, although the Qin King Shimin died in the Qi King's palace, but the dead soldier who started to do it can be said to be the prince's main envoy, and Yuanji also said: "I just want to kill the second brother, how can I do it in my own palace?" This must be the big brother who wants to marry me! ”
We can even guess that when the dead soldiers of the Qi Dynasty Palace assassinated Li Shimin, it was very likely that they would kill the prince together, and then it would be enough to say that the eldest and the second elder did not move their hands to kill each other.
Li Yuan had a total of four concubines, the eldest was built into the second generation, and the old third Xuanba (zi Dade) died early in the tenth year of Daye, no matter how the eldest and second elder died, the crown could only fall on the head of the old fourth Yuanji.
Li Jiancheng regarded Li Yuanji, who harbored evil intentions, as an ally, and even if the Xuanwumen revolution won, his throne would not be stable, because he had promised to let Li Yuanji be the "imperial brother", that is, to be his successor- how could Li Yuanji have the patience to wait for the natural death of his eldest brother?
Li Jiancheng found the wrong ally, and also used the wrong chief of staff, and the one who has been stirring up Prince Jiancheng's attack on the Qin King Shimin is the legendary "Forty-six Friends of the Jia Family (Liu) Building", wei Zhengwei Xuancheng.
Of course, Zhu Jun, a reader of the Sui and Tang dynasty history books, knew that the so-called worship did not exist, but Wei Zheng was indeed from the Wagang Army, and should have had the experience of fighting side by side with Qin Qiongcheng and others, but this "big brother of Wei" did not remember the old feelings at all, but instead gave the prince an idea to harm Wagang Qunxiong: "Recommend Yuan Ji to the north, but lead the Qin dynasty's royal generals Qin Shubao, Wei Chi Jingde, Cheng Zhijie, Duan Zhixuan and Xing... And kill Shu Bao and so on. ”
This is a loss move, but also a trick: Qin Qiong and Cheng Yaojin are both the founding dukes of Li Yuan's Qinfeng, enjoying the treatment of Congyipin, not exactly Li Shimin's generals, and Qin Qiong's weight in Li Yuan's heart is extremely heavy, killing Qin Qiongcheng and biting Jin will not only offend a large number of meritorious generals, but also make Li Yuan angry, and more importantly, it will push Qin Qiong and others who were originally neutral to the opposite side.
Li Shimin's change in Xuanwu Gate may not be very honorable, and he has been conspired in advance, which the Tang Dynasty historians do not deny, and the defeat of Jiancheng Yuanji is not necessarily a bad thing for the Tang Dynasty: if Jiancheng Yuanji killed Li Shimin in front of the Xuanwu Gate, then there must be no Zhenguan rule, Qin Qiongcheng bit jin and other Wagang su will be killed, how can Li Ji, who has a heavy army and a very heavy old feeling, be willing to give up? Li Yuanji helped Crown Prince Jianjian kill King Shimin of Qin, and then he would patiently become his imperial brother-in-law?
