Tang Taizong: Li Shimin, the second emperor of the Tang Dynasty, ascended the throne in 626 AD, reigned for 23 years, 626-649 AD.
On July 2, 626, he launched the "Xuanwumen Rebellion", killed the crown prince Li Jiancheng, the Prince of Qi Li Yuanji, and was crowned crown prince, and on September 3, Li Yuan, the emperor of Tang Gaozu, abdicated, and Li Shimin was proclaimed emperor, with the era name Zhenguan. Why did Li Shimin launch the "Xuanwumen Revolution", and what is the story behind it? Today, let us walk into the history of Datang and review the shadow of the sword and light when the brothers and sisters were killed in the "Change of Xuanwu Gate".

<h1 class="pgc-h-arrow-right" > Prince Li Jiancheng is not a clumsy disciple. </h1>
Li Yuan had 22 princes, of whom four sons were concubines, the eldest son, Li Jiancheng, who was crown prince. The second son, Li Shimin, was crowned king of Qin. The third son, Li Xuanba, was crowned king of Wei. The fourth son, Li Yuanji, was crowned king of Qi. Li Xuanba died young, here we will not elaborate, the rest of the non-concubine princes basically belonged to the melon-eating masses at the time of the "Xuanwumen Change", and we will not discuss it anymore.
First of all, let's say that Li Yuan, the eldest son of Tang Gaozu, is also the crown prince Li Jiancheng. The New Book of Tang says: It is said that Li Jiancheng was an absurd, unlearned, unskilled, unscrupulous, and alcoholic. Is this really the case?
In the "Treatise on the Political History of the Tang Dynasty", it is evaluated: "When he was built as a prince, the bureaucrats he used, such as Wang Jue and Wei Zhengzhi, who were later the famous ministers of the rule of Zuocheng Zhenguan, can be seen that Li Jiancheng was also a man of wisdom. "
The New Book of Tang was organized by Li Shimin, and the evaluation of Li Jiancheng may be unfair, and the "Treatise on the Political History of the Tang Dynasty" is a comment by modern historians, which will be more realistic and objective.
In 617, when the Sui Dynasty was in turmoil and the army was raging, Li Jiancheng helped his father Li Yuan taiyuan to raise an army, and then led Li Shimin to lead an army to attack the West River, captured Huoyi City, resisted the Turks and Tongguan, and finally conquered Chang'an City. After the establishment of the Tang Dynasty, he led an army to repel the Turkic invasion and pacify Shandong. The above are the outstanding achievements of Li Jiancheng when Li Yuan started his family, and this merit is remarkable.
We often say that "the initial stage is the most rare and the most risky time". It can be said that Li Jiancheng helped Li Yuan to raise troops from Taiyuan to Guanzhong, laying the foundation for the establishment of Datang in the most difficult moments of the beginning. New Book of Tang: I once added the above credit to Li Shimin's head, saying how Li Shimin was at this stage, I was skeptical. Because, at the moment when Li Yuan raised an army in Taiyuan, among the three sons, Li Yuan relied most heavily on Li Jiancheng, because Li Jiancheng was 29 years old, Li Shimin was 20 years old, and Li Yuanji was 15 years old.
In 617 AD, when he raised an army in Taiyuan, Li Yuan resolutely disagreed, on the grounds that he could not resist the kindness of Emperor Wen of Sui, and some people said that Li Yuan at this time must have been pretending, and let's not say this, he was actually waiting for a person, this person was his eldest son Li Jiancheng. What did Li Jiancheng do? He was sent to recruit troops, and after Li Jiancheng returned from completing his mission, Li Yuan decided to raise troops, which showed the importance of Li Jiancheng.
In 618, the Sui Dynasty fell, Li Yuan was proclaimed emperor, and Li Jiancheng was crowned crown prince and began to assist Li Yuan in supervising the imperial government. Due to the different status of the crown prince, Li Jiancheng's responsibilities have also undergone great changes, and his focus has also shifted to governing the country. At this moment, the four sides of the separatist forces like Liu Heimin, Wang Shichong, etc., have not been completely cut off, Li Jiancheng, as the crown prince to supervise the country and manage the government, naturally sent troops to suppress the rebellion, Li Yuan handed over to Li Shimin, so that he also laid the foundation for his future political achievements.
<h1 class="pgc-h-arrow-right" > Li Shimin, the King of Qin, is not a shallow lobster. </h1>
In 618, after Li Yuan ascended the throne, the Tang Dynasty mainly had the following separatist forces on all sides. To the north are Liu Wuzhou and Song Jingang, to the south is Wang Shichong, to the east is Dou Jiande, and to the west is Xue Rengao, as shown in the following figure:
In 618, in order to cut off the troubles in the west and stabilize the rear area, Xue Ju, the northwestern separatist force at that time, fell ill and died, and his son Xue Rengao succeeded him as king. Li Yuan ordered Li Shimin to lead an army to conquest. Li Tang won the success of Li Rail, so that Xue Jun's flank was threatened; Li Shimin fought again in shallow water plains, closed his fortress, seized the favorable fighter planes to attack back and forth, and took advantage of the situation to pursue, so that his troops could not be gathered, and thus won. This battle enabled the Tang Dynasty to pacify Longxi, eliminate the worries of the west, and ensure the safety of Guanzhong.
In 619, Liu Wuzhou, a separatist force in the north, attached himself to the Turks and decided to join forces with Song Jingang to raise an army against the Tang, and he had already defeated the Tang army many times in present-day Shanxi, capturing the southwest and other places centered on Taiyuan. It seriously threatened the rule of the Tang Dynasty, and everyone knew that Taiyuan was Li Yuan's old base camp. As a result, Li Shimin again led an army to conquest Liu Wuzhou, the Song army was defeated, its main general Chi Jingde surrendered, Liu Wuzhou and Song Jingang fled to the Turks, and the Tang army recovered Taiyuan and the warlord forces in the north, stabilizing the security of the north.
In 621 AD, Li Shimin led 10 elite troops to the south, and fought a decisive battle with Wang Shichong of Henan and Dou Jiande of Hebei at Hugaoguan in Henan, in which the Tang army won a decisive victory, annihilating the two major separatist forces in the Central Plains in one fell swoop, enabling the Tang Dynasty to gain the right to rule Hebei, Henan and other places, laying the foundation for the basic territory of the Tang Dynasty. After winning the Battle of Tiger Prison Pass, Li Shimin's exploits were fully demonstrated, and his personal prestige was gradually recognized by the imperial court, especially when Banshi returned to Beijing, Li Yuan gave his son great glory and organized a solemn welcome for the chang'an army and people.
The above is Li Shimin's merits, from which we can see that most of the Tang Dynasty's jiangshan were fought by him in the southern conquest and the northern war, can you say that he can not be proud of his achievements? Under such circumstances, was he not at all impressed by imperial power?

In the early days of the tang dynasty, in order to create the foundation of the Tang Dynasty, Li Jian's success was indispensable. After the founding of the People's Republic of China, in order to lay the foundation of the early Tang Dynasty, Li Shimin conquered the four sides. From the point of view of merit, especially after the establishment of the Tang Dynasty, they are one of the main internal, Li Jiancheng is mainly based on civil rule, one is outside the main, Li Shimin is mainly known for martial arts, if you talk about merit, they are all among Bo Zhong, you can divide the autumn and autumn, it is not easy to distinguish between the good and the bad.
In terms of camp, in the early Tang Dynasty, the crown prince Li Jiancheng, during the period of supervising the state administration, drew together a large number of political teams, and in the prince's mansion, there was the first strategist wei Zheng, the first secretary general was Wang Gui, the first reserve force was Luo Yi, and the first emergency team leader was Xue Wanche. During the Northern Expedition of the Qin Dynasty, Li Shimin, the King of Qin, gathered a large number of civilian and military generals, including Fang Xuanling and Du Ruyi, and the military generals had the eldest grandson Wu Jie, Wei Chi Jingde, and so on.
In terms of troop strength, there were two thousand long Forest troops in the Prince's Mansion, three hundred Turkic soldiers selected by Luo Yi, the king of Beiping, and eight hundred death squads of Li Yuanji, the king of Qi. The Qin Dynasty Mansion was full of eight hundred guards. Judging from the comparison of military forces before the mutiny, the crown prince Li Jiancheng wanted to defeat Li Shimin, the king of Qin. However, Li Shimin led his troops to fight wars for many years, and he was stronger than Li Jiancheng in military command, and he fought a lot of battles with fewer victories and more battles.
On the backstage, Li Yuan was determined to pass the throne to the crown prince Li Jiancheng on the issue of imperial power and the succession to the throne, and even though he admired Li Shimin very much, Li Yuanji, the king of Qi, was also firmly supportive of his eldest brother Li Shimin, and he even repeatedly suggested using other methods to get rid of Li Shimin, but li Jiancheng's hesitant character was rejected. Coupled with the orthodoxy of the eldest son of most of the courtiers, Li Shimin's supporters were few and far between.
It is in this context and strength, what is the result?
In 626 AD, the Prince's Mansion and the Qin Dynasty Palace had reached a critical moment of sword-rattling, and both sides had made full preparations for the struggle for imperial power, and whoever could "be determined, unexpected, and unprepared" could become the final victor. On July 2, Li Shimin led his own team of civilian generals into the dynasty and set up an ambush at Xuanwu Gate, but Li Jiancheng and Li Yuanji did not know how poor the intelligence work was, until Li Jiancheng and Li Yuanji came to the Linhu Hall, they noticed the change, the result... Everyone knows, Li Jiancheng and Li Yuanji were killed, and Li Shimin was crowned prince. On September 3, 626, Li Shimin ascended the throne as emperor with the era name Zhenguan, thus creating the "rule of Zhenguan" of the Tang Dynasty.
