Li Shimin has made great achievements, why was he not made the crown prince?

In ancient China, the prince was generally the eldest son, and Li Jiancheng was also a very talented person, his ability was not inferior to Li Shimin, and he was the eldest son, so of course the identity of the prince was not Li Shimin's turn.

Because Li Yuan still represents the Guanlong Group, and Li Shimin also has Shandong Haoqiang behind him.

Because he was not the eldest son, and the eldest son Li Jiancheng at that time was also very good.

Because Li Jiancheng was also very good at that time, and Li Jiancheng was still the eldest son.

The main reasons why Li Shimin wanted to make Li Zhi the crown prince are as follows:

First, the crown prince Li Chengqian, who was the same as his mother, and Li Tai, the king of Wei, died by themselves, which eventually led to Li Shimin having to pass on to Li Zhi, the king of Jin. The second is the best political choice made by Li Zhi's uncles, the eldest grandson Wuji and Chu Suiliang, for the sake of their own political future.

Tang Gaozong Li Zhi, the word is good, the third emperor of the Tang Dynasty, the ninth son of Tang Taizong Li Shimin, the mother is the eldest grandson of the Holy Empress Wendeshun, the former prince Li Chengqian, and the king of Wei Li Tai are the same brother.

In June of the second year of Zhenguan, Li Zhi was born in the main hall of the East Palace. Zhenguan was crowned king of Jin in the fifth year, and the crown prince Li Chengqian and the second son Li Tai, the king of Wei, were deposed one after another, and he was registered as the crown prince in the seventeenth year of Zhenguan. In the twenty-third year of Zhenguan, Tang Taizong died, and the crown prince Li Zhi ascended the throne for Tang Gaozong.

At the beginning of his reign, Tang Gaozong continued to implement the various political and economic systems formulated by Taizong, and Li Tao, the eldest grandson Wuji, and Chu Suiliang jointly assisted the government. Because he is diligent in political affairs, "the people of Fu'an, there is the legacy of Zhenguan, and the history is called "the rule of Yonghui". Gojong also insisted on his own position on the issue of deposing the empress, excluding the interference of the patriarchal faction.

Five years after Xianqing, Gojong was often dizzy and dizzy, which affected the handling of government affairs.

Empress Wu took the opportunity to participate in state affairs. Gaozong's health was poor, and the trend of transferring power from Gaozong to Wu Zetian gradually took shape. During the reign of Tang Gaozong, he successively destroyed the Western Turks, Baekje, and Goguryeo.

During the reign of Emperor Gojong, the territory of the Tang Dynasty was the largest, stretching from the Korean Peninsula in the east, expanding the Aral Sea in the west, encompassing Lake Baikal in the north, and reaching central Vietnam in the south, which lasted for 32 years.

Li Shimin passed the throne to his ninth son, Li Zhi. He had a total of fourteen sons, of which the eldest grandson empress gave birth to three, and all three of them were made princes, but in the end only Li Zhi became the emperor.

In fact, at the beginning, Li Shimin was more optimistic about his eldest son Li Chengqian, because he was born smart and clever, and he was the first child, so it was natural for him to be the prince.

But Wan Chencheng judged that he didn't expect that this son would later fall into a "cripple", with bad legs and feet, no emperor's appearance, and his personality has changed, he is becoming more and more reckless, and he doesn't do his job all day long, so he was abolished later.

Because there is an important principle in the rules for the selection of princes in ancient times, that is, to establish the eldest and not the young, and although Li Shimin said that his ability is very strong, he is not the eldest son after all, so Li Yuan still followed the rules and chose Li Jiancheng as the prince, even if Li Yuan wanted to re-elect the prince later, because Li Jiancheng did not make a big mistake, Li Yuan had no reason to do so.

Li Yuan actually always knew Li Shimin's ambitions, so in order to take care of the cannibalism between these two brothers, he followed an ancient rule, that is, the primogeniture inheritance system, he felt that he followed the ancient system and let his eldest son Li Jiancheng ascend the throne, so that Li Shimin would not have two hearts, and would only assist his brother wholeheartedly, because the law of the ancient ancestors was immutable, and the primogeniture inheritance system had been passed down for thousands of years, but Li Yuan made Li Jiancheng the prince on the one hand, but on the other hand, he did not return Li Shimin's power. He also wants Li Shimin to continue to serve himself and Li Jiancheng.

In the Xuanwumen Change, Li Shimin killed his eldest brother and third brother, forced his father back, and thus became the emperor, beginning his 23-year reign, during which he and Empress Changsun gave birth to a total of three sons, Li Chengqian, Li Tai, and Li Zhi.

Li Chengqian was made the crown prince since he was a child, but as he grew up, there was a little problem with his legs and feet, and Li Tai felt that his eldest brother was a disabled person, and out of the yearning for the throne, so he had the idea of abolishing the prince, these two people are not good stubble, and the fight is inextricable, after Li Shimin saw this scene, he couldn't help but think of the scene when he won the throne, how familiar it was, in order to avoid tragedy, so he announced that his third son Li Zhi would be the crown prince.

There is another reason why Li Shimin abolished Li Chengqian, that is, Li Chengqian doted on a beautiful man called Satisfactory Heart very much, but Tang Taizong knew about it and killed Satisfactory Heart, Li Shimin thought that Li Chengqian was good at Longyang, and Li Taixin was ruthless and unsuitable to be the emperor, so according to this rank, Li Zhi would be reached, so Li Zhi's throne could be regarded as picked up.

disliked him, and later the prince rebelled, which made Li Shimin even more tired of him. I like my second brother Li Tai.

The first prince himself was mediocre and talentless, only knew how to eat, drink and have fun, and did not have the slightest sense of being prepared for danger in times of peace, which was very unfavorable to the Tang Dynasty, which was prosperous on the surface but in fact had various economic and political and military problems that arose as a result.

The second prince thinks about the throne with a heart, and his small actions in private make Li Shimin feel threatened, and those in high positions will inevitably be short-sighted for a long time.

It was Li Chengqian, the son of Empress Changsun, because he wanted to seek power and carry out a coup d'état. He was deposed as a concubine.

Li Chengqian (year, month, day), born in the Chengqian Palace, named "Chengqian", implying the inheritance of the imperial industry, the meaning of the commander-in-chief. Tang Gaozu Wude three years (Feng Hengshan King. Tang Taizong ascended the throne as the crown prince at the age of eight.

I don't want to like sound and sex in adulthood, and roam excessively. But he was afraid of Taizong, so he played duplicity, and in front of Taizong, he would be loyal and filial; After retiring from the dynasty and returning to the palace, he was satisfied with a group of small blasphemous, Cheng Qian, who was more than ten years old, beautiful and good at singing and dancing. When Taizong found out, he was furious and killed.

He had a foot disease, and he was afraid that he would be deposed because of this, and he was deeply jealous of Li Tai, the king of Wei, who was loved by Taizong. In the seventeenth year of Zhenguan ( Cheng Qian and the Han King Li Yuanchang, Hou Junji, Li Anyan, Du He (Du Ruhui's son), Zhao Jie (the son of Princess Changguang) and others conspired to rebel, but it did not succeed, and was informant by Su Gan Chengji, and after being imprisoned, he was deposed as a concubine and migrated to Qianzhou, where he died two years later.
