After Zhu Yuanzhang's death, emperor's grandson Zhu Yunjiao succeeded to the throne. Before Emperor Jianwen's ass could sit still, Zhu Di rebelled under the banner of "Qing Jun's side, Jing Guo's difficulty".
Old Zhu took a series of measures before his death, hoping that Zhu Yunjiao could sit on the throne steadily. For this reason, Zhu Yuanzhang, who was fierce and fierce, killed heroes indiscriminately, and did not hesitate to leave behind a name for eternity, of course, before his death, Lao Zhu also left a holy will for his sons - the kings should stay in the fiefdom and not enter the capital.
Despite this, Zhu Di still replaced Emperor Jianwen in just four years. So why couldn't Zhu Yunjiao defeat Zhu Di in the Battle of Jingnan, was he defeated by his family?
The reason why this issue is mentioned is because of Zhu Yunjiao's series of practices toward Zhu Di after he succeeded to the throne.
Before the Battle of Jingnan, the imperial court had manpower to persuade Zhu Yunjiao to detain Zhu Di's son to blackmail the other side. Emperor Jianwen hesitated and did not agree. Even when the swords and soldiers were facing each other, Zhu Yunjiao also issued an edict to his subordinates, not allowing anyone to harm his uncle Zhu Di, so as not to let him bear the charge of killing his uncle.
Looking at Zhu Yunjiao's attitude towards Zhu Di, it is really good, which is also what makes many people puzzled. Since it has reached the point where water and fire are intolerable, and you are dead and alive, Zhu Yunjiao's approach is really counterintuitive.
Zhu Yunjiao was defeated, but he could not simply think that he had lost to his family.
Since the cutting of the domain, Zhu Yunjiao was not only aimed at Zhu Di, of course, Zhu Di was the focus, after all, zhu Yuanzhang's first three sons had died at that time, and Zhu Di became the longest of the princes. However, before Zhu Di, the Kings of Zhou, Dai, Qi, and Xiang were either deposed or killed.
If this logic is followed, then there is no need for Zhu Yunjiao to be merciful to his biggest opponent, otherwise, Zhu Yunjiao will not be merciful, but a fool.
Zhu Yuanzhang chose Zhu Yunjiao, in fact, there are many reasons, one of which is to look at his generosity and benevolence, which Zhu Yunjiao and his father Zhu Biao still have some similarities, these two people are exactly the opposite of Zhu Yuanzhang's personality.
Zhu Yuanzhang was not confused, he also knew that he could only make meritorious achievements in this life, so the heavy responsibility of guarding the Zhu family's world could only be left to such a successor, after all, what the country needed was to recuperate.
Originally, the crown prince was Zhu Biao, and the emperor also cultivated Zhu Biao with all his heart, and if Zhu Biao did not die, the throne would not be able to take Zhu Yunjiao's turn. Although proper training as an imperial grandson is necessary, it is not cultivated as a successor.
Therefore, he succeeded to the throne as emperor at a young age, in addition to Zhu Yuanzhang's admonition, I am afraid that Zhu Yunjiao can only come by nature. However, Zhu Yunjiao basically had nothing to do except for his gentle and elegant body. Compared with Zhu Di and a bunch of other emperor uncles, their ability is a big difference.
But one thing Zhu Yunjue is clear about, and that is the stability of imperial power. Although he did not have the ability to govern the country, he was not ignorant of history. Since ancient times, the royal family is ruthless, even brothers, grandfathers and children can kill each other, not to mention uncles and nephews? This is all bloody facts, after all, the temptation of the emperor's throne is really too great, which is also the reason why Zhu Yunjiao wants to cut the domain.
Therefore, Zhu Yunjiao will never think of any uncle-nephew friendship and be merciful to Zhu Di's subordinates, he did have a time of kindness and softness, but it was definitely not an uncle-nephew feeling, but Zhu Yunjiao's own personality.
This is one of the reasons why Zhu Yunjiao failed, and another important reason is that there are no generals available in the DPRK, which is also fatal.
Since the founding of the People's Republic of China, Zhu Yuanzhang has set up the Jinyi Guard and various kinds of torture, killing a large number of founding heroes, most of whom are military generals. Therefore, when Zhu Yunjiao ascended the throne, he was faced with a situation where there were no generals available. So much so that Zhu Yunjiao used Li Jinglong's straw bag, he would not command the troops to fight at all, and he was repeatedly defeated in battles with Zhu Di, and this pot Zhu Yuanzhang was determined.
Therefore, there are many reasons for the failure of the Jianwen Emperor Zhu Yunjiao, and it is not decided by him alone or by a single factor.
