Why did Li Shimin launch the change of Xuanwu Gate?

Because he got the news that Lee was going to kill him, he decided to strike first.

Li Shimin's strategy is to rise in Taiyuan. Tang gaozu promised to make him a prince when it was done, but after Tang gaozu established the Tang Dynasty, Li Jian became a prince.

After pacifying the world, he gained great fame, and Li immediately joined hands with Li Yuanji to crowd him out. Tang Gaozu's indecision also made the decrees of the DPRK and China conflict with each other, which accelerated the confrontation between philosophers. ?

Li Dage's crown prince knew that he would not surrender to the throne, and thought that he laid the foundation for the establishment of the Tang Dynasty. Therefore, he became more and more suspicious that Li and his fourth brother, Li Yuanji and Qi Wang, ministers of these two factions were in conflict with each other.

Lee was poisoned and killed. Among them, the Prime Minister Pei Ji, the counselor Wang Jue, and the East Palace Guard General followed Li and Li Yuanji.

Du Ruhui and Fang were counselors of Qin, while Qin, Duan, Hou and Fang were generals, following Li Shimin. Prime Minister Chen Hechen and his son secretly supported him. The other generals, Li Jing and Xu Shiqi, and the minister, Yu Shiwen, remained neutral.

In the ninth year of Wude (626), the Turks invaded the Tang Dynasty. Li Xiang suggested that Li Yuanji should be the commander in chief to go to the Turks.

Wang Chang, who served as Cheng Geng (the official in charge of timing) in the Prince's East Palace, has been bought by Li Shimin, the king of Qin, and has become a thorn in Li Shimin's side. He quietly told: "Li wants to control the military forces of the king of Qin and is going to ambush the king of Qin in Kunming Pool." So Li Shimin decided to strike first.

On June 2, 626, near the Xuanwu Gate in Chang 'an Miyagi, the imperial capital, the Crown Prince Li and Yuanji Wang were shot and killed, which is called "the change of Xuanwu Gate" in history.

Extended data:

Li Shimin, the king of Qin, was unconvinced that Li Jian had become a prince because he had made meritorious military service abroad for a long time, so he tried his best to replace him.

In June of the seventh year of Wude, the king of Qin created an incident in which Wen Yang participated, which led to people falsely accusing the king of Qin of collaborating with the rebels. Finally, Tang Gaozu exiled three brothers, Wang Jue, Wei Ting and Du Yan, Qin Gong's chief of staff. ?

Since then, Qin Gong has been in constant friction with the East Palace. In the ninth year of Wude (626), fearing the power of Qin Gong, Li suggested that Li Yuan expel Fang and Du Ruhui from Qin Gong and strictly forbid them to meet each other. ?

Most of the civil servants in the palace of Qin Dynasty were dismissed from their official positions, and only Mowgli, Gao Shilian, Weichi Gong and Zhang stayed in the palace. They are in a state of panic, so they suggest taking action as soon as possible to kill Li and force him to abdicate. ?

On the morning of June 4th, the leaders, Weichi Gong, Hou and others set an ambush at Xuanwu Gate. Prince Li and Li Yuanji, King of Qi, were called into the palace and went to the temple by the lake. They felt something was wrong and turned to return to the East Palace. Yelling after him, he shot Li with an arrow.

, Xue Wanche, Xie and other East Palace generals and Qi learned that Li was killed, led two thousand military forces to storm Xuanwu Gate, and killed Jing Hongjun, Lu and other Xuanwu Gate generals.

Xue Wanche encouraged the soldiers to attack Qin, and Qin Zhong was frightened to disgrace, so he cut off the heads of Li and Li Yuanji and publicly displayed them, which made the morale of the military forces in the East Palace lose greatly. In this coup, all five sons of Li were killed and the whole family was expelled from the royal family. ?

On Jiazi Day (September 4th, 626) on August 9th, Wude nine years, Prince Li Shimin proclaimed himself the emperor in the Xiande Hall of the East Palace, and for the sake of Emperor Taizong, he granted amnesty to the whole world. From then on, he began a brilliant career as an emperor, and he ascended the throne on the first day of the first month of the second year (June 23, 65438+June 23, 627). During the period of Emperor Taizong, the literary ambition and martial arts were the best in the world, which was called "the rule of Zhenguan" in history.

In the second year of Zhenguan (628), Li Shimin named Li Jian the king of interests and practiced "seclusion". Lee was reburied with a royal gift. In the 16th year of Zhenguan (642), Li Shimin posthumously awarded Li Jian as the Crown Prince.
