Let's look at Yang Guang first. At first, Yang Guang was not a candidate for the crown prince. Through various means, he made Emperor Wendi of Sui Dynasty abolish the Crown Prince Yong Yang and replace him himself.
However, Emperor Wendi later discovered that he actually intended to have sex with his beloved wife Chen. In a rage, he wanted to change his position to Yong Yang. After Yang Guang knew it, he quickly seized power and ascended the throne smoothly. Then, in the process of Yang Di's accession to the throne, one is the participation of concubines in the harem, and the other is the use of various intrigues and military means.
More than twenty years later, Li Shimin launched the famous Xuanwumen Revolution and took over the throne of Tang Gaozong from his father Tang Yuan. In fact, the change of Xuanwu Gate has many similarities with the change of Yang Guang's seizure of power in that year.
First of all, Li Shimin and Yang Guang were not established heirs to the throne at first. Secondly, in the process of their upper operation, all the concubines in the harem are involved. Finally, they all used various schemes and force to inherit their father's throne.
To say that Li Yuan contributed the most to the establishment of the Tang Dynasty, everyone knows that Li Shimin contributed the most. But Li Shimin is not Tang Gaozu's eldest son, so Tang Gaozu chose his eldest son Li Jian as the prince according to tradition, and Tang Gaozu only gave him a king of Qin for his second son Li Shimin, who made the greatest contribution.
However, Prince Li is far behind in both ability and reputation. He was on pins and needles from the moment he sat on the throne of the prince; And this end is also annoyed and helpless, not only when he becomes a prince, but also when it comes to anything important, he is thrown to him to do it, throwing his head and blood into a dog, and often embarrassing his father's two concubines, namely Yin Defa, who are closely related to Prince Li.
Zhang Jieyu and Yin Defai were originally beautiful women who were placed in Jin Yanggong by Emperor Yang Di. As we know, there is a very important reason for Tang Gaozu to arise, because he got his hands on the women in Jingyang Palace, because this is called "molesting the harem", which is a capital crime!
So Li Yuancai was forced to arise. In this way, Zhang Jieyu and Yin Defai, who were originally in Jingyang Palace, naturally became his concubines after Li Yuancai proclaimed himself emperor, and they were much loved.
On one occasion, Li Shimin won the battle and returned home in triumph, bringing back many trophies. As a rule, he will turn over these gold, silver and jewelry coefficients to the state treasury, and then the emperor will reward those who have made meritorious deeds.
But this time, before the soldiers were rewarded, Zhang Jieyu and Yin Defai were spoiled, so they pestered Tang gaozu to be coquettish. Li Yuan, who couldn't bear to be spoiled by beautiful women, was very clever and said to the two love princesses, then you should go to the king of Qin to pick something good in the name of "sympathy"!
So Zhang Jieyu and Yin Defa went to Li Shimin to ask questions under the guise of "sympathy". As a result, all the soldiers who fought with Li Shimin were indignant-we worked hard to get something back, and our brothers haven't scored yet. Why do the two harem concubines have to beat us to it? Li Shimin was naturally angry, so she refused the request of two harem queens.
From then on, Zhang Jieyu and Yin Defa held a grudge against Li Shimin. It happened that Prince Li and King Li Yuanji of Qi had long regarded Li Shimin as the biggest threat. Zhang Jieyu and Yin Defa chose to form an alliance with the Prince and kept close contact with him. Since then, they have targeted the King of Qin everywhere and given Li Shimin all kinds of little shoes in Tang Gaozu's ear.
In 626 AD, the Prince and Li Yuanji plotted to get rid of it, but they felt the danger ahead of time, so they decided to strike first. On June 3 of that year, he went to the palace to visit his father. As soon as they met, they threw out a heavy news. He told Tang Gaozu that the prince and Li Yuanji defiled the harem and got the most beloved Zhang Jieyu and Yin Defa!
Tang Gaozu a listen to, naturally refused to believe, but think about it, the two concubines who do have a very close relationship with the prince here, so Tang Gaozu is a little shaken. Since Li Shimin is convinced of this, please ask the prince to come and confront him face to face and make the problem clear.
After Li and Li Yuanji received the instructions to enter the palace, one thought it was necessary to clarify the framing face to face as soon as possible, while the other thought it was a trap. But in the end, Prince Li decided to enter the palace, because as long as he didn't go, he would aggravate his doubts about them.
It was this decision to enter the palace that ruined his and Li Yuanji's life, and the Xuanwu Gate in Li Shimin was successfully implemented. To make matters worse, Li Shimin insisted on the principle of extinction. Later, Li and Li Yuanji's family were killed. Only Li Yuanji's wife Yang entered the harem because of her beauty.
The cruel family struggle and chaotic relationship also gave the dirty Tang a bad name, but who would have thought that the fuse of this appalling court civil strife was actually lit by two humble concubines? Tang Gaozu was smart enough to ask his concubine to "mourn" and even set off the powder keg of the Xuanwumen uprising. What a clever mistake!
