I remember that in the middle school history textbooks of the early years of this century, there was such an exercise: Who else is the king who won the throne with Zhu Di? The standard answer is Li Shimin. The reason is that Zhu Di and Li Shimin both obtained the throne by usurping the throne by the clan.
Then, why did Li Shimin dare to launch the "Xuanwumen Revolution" when Li Yuan was alive, but Zhu Di did not dare to rebel when Zhu Yuanzhang was alive?
Personal Feelings:
Development route
The establishment of the Tang Dynasty was based on the last years of the Sui Dynasty, when the Sui Dynasty bureaucrat Li Yuan established The Sui Gong Emperor as a puppet emperor and the Sui Emperor Yaozun as the Taishang Emperor, and then after the death of the Sui Emperor, Li Yuan obtained the throne in the form of accepting the Throne of The Sui Gong Emperor.
However, at this time, the world was in chaos, and although Li Yuan divided one side to establish the Tang Dynasty, the Tang Dynasty wanted to stand on its own, and it had to expand. This gave Li Yuan's second son, Li Shimin, the opportunity to cultivate his own forces in the war against other separatist forces. So that after the unification of the Tang Dynasty, Li Yuan was also jealous that Li Shimin's power was too great, so he secretly supported the crown prince Li Jiancheng to cultivate his own forces, hoping to suppress Li Shimin.
It is not difficult to see from this detail: for Li Yuan, the situation in the imperial court has gotten somewhat out of control.
The "Xuanwumen Change" was essentially a counterattack by Li Shimin against Li Yuan's suppression. The final result was that Li Jiancheng's clique was eliminated and Li Yuan was forced to abdicate.
Zhu Di's development route is completely different from Li Shimin's.
In the last year of the Yuan Dynasty, the Red Turban Army divided the south, and the world fell into a situation of chaos: one moment was the Northern Expedition of the Red Turban Army, the other was the Yuan Army going south, Zhu Yuanzhang initially joined the Red Turban Army, and became a warlord of the Han and Song dynasties. And with this, he started his career and established the Ming Dynasty.
When Zhu Yuanzhang joined the Red Turban Army, Zhu Di was not yet born. Therefore, for the establishment of the Ming Dynasty regime, Zhu Di did not contribute, and of course could not cultivate enough forces and dangers to confront Zhu Yuanzhang. Therefore, even if Zhu Di had the intention of plotting rebellion when Zhu Yuanzhang was alive, he did not have this opportunity and conditions.
Active and passive
In addition, Li Shimin and Zhu Di are completely different.
For the change of Xuanwumen, it can be understood as an inevitability of the history of the early Tang Dynasty: on the one hand, the powerful King of Qin, because of his strength and prestige, he had a huge ambition. It can be said that the change in Xuanwumen was a premeditated coup d'état, and Li Shimin had a certain initiative in this coup.
Zhu Di is different.
When Zhu Yuanzhang was alive, Zhu Di was only a vassal of Zhu Yuanzhang. After Zhu Yuanzhang's death, Emperor Jianwen began to withdraw the domain and persecute the kings of the domain. Therefore, Zhu Di could only survive and launch the "Battle of Jingnan". The "Battle of Jingnan" is different from the "Change of Xuanwumen", the "Battle of Jingnan" was a big gamble for Zhu Di, and Zhu Di did not have much chance of winning at first - after all, the Ming Dynasty used the strength of the whole country to deal with Zhu Di, the king of the clan, whether in human or financial resources, Zhu Di was not superior, or even in a passive state. As for the "change of Xuanwumen", Li Shimin has great certainty and initiative.
