After Li Yuan was forced to abdicate, he thought of a "conspiracy move", which made Li Shimin have a headache
When it comes to the founding emperor of the Great Unification Dynasty, the one with the least sense of existence in history is Li Yuan, the high ancestor of the Tang Dynasty. Li Yuan and Yang Guang, emperors of the Sui Dynasty, were cousins, and their mothers were sisters. Li Yuan's own talent did not defeat the other founding emperors, but he gave birth to a son Li Shimin, who was more ambitious and capable than him. In the last years of the Sui Dynasty, when the world was in turmoil, Li Yuan still faced the Sui Dynasty. If it were not for Li Shimin and his advisers who had committed capital crimes by deceiving Li Yuan and Emperor Yang's concubines after drinking, they would not have been able to create a prosperous Tang Dynasty.
On July 2, 626, Li Shimin, the King of Qin, led his troops to assassinate Li Jiancheng and Li Yuanji, the princes of the State of Qi, at Xuanwu Gate, which is known in history as the "Change of Xuanwu Gate". After Xuanwumen changed the law, although Li Shimin, the King of Qin, had complete control of the imperial court, in this case, Li Yuan was forced to make him crown prince, and Zen Buddhism was on him. He became an emperor without real power. Li Shimin staged a coup d'état, on the one hand, because he had the original intention of seizing power, and on the other hand, if he did not go further, a group of capable people under his command might threaten him in turn.
After succeeding the emperor, Li Shimin changed the Yuan Dynasty to "Zhenguan" and, with the help of a number of famous ministers such as Wei Zheng, created the first "Zhenguan" rule of the Tang Dynasty. During Li Shimin's reign, he changed the expedient strategy of Li Yuan and the Turkic courtiers to seek peace, and turned to conscription, which gave rise to the authority of the Tang Dynasty. Li Shimin not only governs the country and the country, but also can be called a generation of Ming emperors. He cared about the suffering of the people and even issued decrees that there was no need to hide his name. Although Li Shimin had stains such as killing his brothers and occupying his sister-in-law, as an emperor, he was very outstanding
Li Shimin won his dream of the throne, and Li Yuan did not want him to live so comfortably. After all, he scolded Li Shimin at the beginning: "You killed my children and grandchildren, and you will kill your children and grandchildren in the future!" In order to inherit the descendants of the old Li family, Li Yuan did not idle after retirement. He did not want to get Li Shimin's rights, but let him give himself more beautiful women. Although Li Yuan was 60 years old when he abdicated, his fertility was still strong. During the ten years of emperor Tai's reign, Li Yuan added twenty or thirty brothers and sisters to Li Shimin.
Half of these children were boys, that is, Li Shimin had more than ten younger brothers than his son. Li Yuan's youngest son, Li Yuanbao, was even younger than Li Shimin's grandson, Li Xin. At the time of Li Yuan's death, these children were nothing more than suckling bear children, and there was no threat to Li Shimin's imperial power. In order to seize power, Li Shimin killed Li Jiancheng and Li Yuanji. He was reluctant to attack his brother who was not a threat. Because he was his brother, Li Shimin also generously feuded with the state and cherished them, such as Li Yuanbao.
Because they had been spoiled by Li Yuan since childhood, these kings never took the local officials and people seriously, and sent them to the Daming Palace in piles. Li Shimin had no choice but to move his brothers to a nest from time to time.
