Zhu Di was the fourth son of Zhu Yuanzhang, the founding emperor of the Ming Dynasty, but he did not succeed to the throne as crown prince. Instead, he overthrew his nephew Emperor Jianwen in the form of rebellion and ousted him from power.
So since this is the case, he has every reason to change the name of the country, such as Yan, after all, he is the King of Yan himself. In history, many dynasties have used this as a national name, such as Sima Yan of the Jin Dynasty, who was the King of Jin. Li Yuan of the Tang Dynasty, he was originally the Duke of Tang.
Then, after the Battle of Jingnan, why didn't Zhu Di change the name of the country, but only moved the capital?
Zhu Di's rebellion and the ancient peasant uprising are not the same thing, and many peasant uprisings are bound to change the country after they are successful, just like Zhu Yuanzhang, which is also normal.
But Zhu Di was different, and he raised an army to fight the slogan of the Qingjun side, which meant that the emperor had courtiers around him and wanted to help the emperor on the side of the Qing jun. In fact, this is mainly stipulated in the "Ancestral Training of the Emperor ming" in Zhu Yuanzhang's period: "If there is no righteous subject in the dynasty, and there is a treachery within, it will raise an army to rebuke it, so as to clean up the side of the king." ”
In Zhu Di's view, Emperor Jianwen's two generals Qi Tai and Huang Zicheng were traitors, and it was through the flickering of these two people that Emperor Jianwen wanted to cut the domain.
In fact, this is completely fictitious, but the angle is different. This did give Zhu Di an opportunity, but Zhu Yuanzhang was not confused, in fact, there was another article in the ancestral training, the emperor first summoned the king of the domain, the king of the domain could raise an army, and after successfully eliminating the traitors, he would leave the capital within five days.
Zhu Yuanzhang's purpose was not to let the king of the clan replace him, but to help under the premise of the old family.
However, just after Zhu Di invaded the city of Nanjing, emperor Zhu Yunjiao disappeared, and it is said that he went into exile overseas, which is why Zhu Di sent people to look for him several times later. It is also said that he was burned to death.
But even if Emperor Jianwen died, he still had a son, and at this time Zhu Di could not become the first successor, Zhu Wengui was still there.
Zhu Di had no intention of becoming Emperor Jianwen's successor. After entering Nanjing, he chose to honor Xiaoling first. Before Zhu Yuanzhang's spirit, Zhu Di counted the various crimes committed by the Jianwen Emperor Zhu Yunjiao, the core of which was that Zhu Yunjiao did not obey the ancestral precepts and was not a qualified emperor, so he directly did not recognize the throne of Emperor Jianwen.
Directly erased Emperor Jianwen in recent years, and he was more like the second emperor after Zhu Yuanzhang. In this way, Zhu Di ranked fourth, the first three were dead, he was the eldest son, and it was natural to take over the shift, and had nothing to do with Emperor Jianwen.
If he changed the name of the country to "Yan", then there would be no reason to succeed Zhu Yuanzhang, and he would become a complete rebel.
Although Zhu Di braved the world to rebel, but things were done, he was not willing to lose this face, so he did not look for Zhu Yunjiao all the time, just hoping to make his ascension to the throne become logical.
From another point of view, the whole world knows that he Zhu Di has created a rebellion, and the other sons of the old Zhu family also know that he has driven away his nephew, but after all, this is the family affair of the old Zhu family, not Li Zicheng's kind of peasant uprising, and Zhu Di cannot shake his arms and get much support.
However, if Zhu Di changed the name of the country, then he would completely go to the opposite side of the old Zhu family, which was also a huge problem for the stability of his own throne.
As for moving the capital, this does not affect anything. After all, Zhu Yuanzhang did not want to see Nanjing, and also planned to move the capital, but various reasons did not come to fruition.
