In the long history of five thousand years, the continuous change of dynasties, the world's yearning for power, led to a series of wars and disasters, in order to obtain the supreme imperial power, in the Qing Dynasty there was the famous "Nine Dragons Seizure" incident, and today we return to the Tang Dynasty to see how a generation of monarchs Li Shimin slowly ascended to the emperor's throne.
Speaking of Tang Taizong Li Shimin, he was the second son of Emperor Gaozong of Tang at that time, Li Yuan, in ancient times, the candidate to inherit the throne or become the crown prince must be the eldest son of The Emperor, which is clearly the first son of the emperor, and at that time Li Yuan had four sons, the eldest son Li Jiancheng, the second son Li Shimin, the third son Li Yuanji and the fourth son Li Yuanba, after reading the Sui and Tang Dynasties, everyone knows that the fourth son died unfortunately during the conquest of Wagang in the early Tang Dynasty, and finally only three brothers were left. In the process of the Tang Dynasty's unification of the world, Li Shimin repeatedly built up qigong in the process of conquest, and was deeply loved by his father, and the eldest brother Li Jiancheng, as the crown prince, was assigned to supervise state affairs and rarely led troops to the expedition.
In 618, Li Yuan established the historical Tang Dynasty, Li Yuan called the emperor Tang Gaozu, Li Jiancheng was made crown prince, Li Shimin was made the King of Qin, and Li Yuanji was made the King of Qi. At both the court and the public, Li Shimin's prestige far exceeded that of the crown prince Li Jiancheng, and Li Jiancheng, fearing that his position as crown prince would be threatened, so he deliberately conspired with Li Yuanji, the king of Qi, to meet with Li Yuan, the emperor of Tang Gaozu, saying that Li Shimin had outstanding military achievements, a large number of generals under his command, and a large number of capable people, and he must not be willing to be only a small King of Qin, but Li Yuan, who had an indecisive personality, never made a decision, resulting in mutual disputes in the government decrees in the dprk and quickly accelerating the escalation of the contradictions between the two brothers.
The final flashpoint was June 3, 626 AD. Li Shimin exposed to Emperor Gaozong of Tang Li Yuan that the crown prince Li Jiancheng and his third brother Li Yuanji had committed wrongdoing in the harem, and Tang Gaozu was still unable to convict the two sons, because once this scandal was passed out, it would certainly be unfavorable to the newly established Li family regime.
So where is xuanwu gate located in the Chang'an City Imperial Palace? Why did Li Shimin choose Xuanwumen as the place to launch the incident? According to historical records, Xuanwu Gate in the Tang Dynasty Imperial Palace Taiji Palace and Daming Palace north gate, and Taiji Palace was the highest political power center of the Tang Dynasty at that time, the usual size of the government decrees are transmitted to the outside, The reason why Li Shimin chose this place is to hope that in the shortest time can grasp the situation, in addition to this reason, this gate is also Li Jiancheng and Li Yuanji into the palace must pass through, and easy to defend and difficult to attack, the city gate is closed, can completely cut off foreign aid, regardless of the time of day or geography, Xuanwu Gate is the best choice.
