In 1392, the crown prince Zhu Biao died of illness, and Zhu Yuanzhang made Zhu Biao's second son Zhu Yunjiao the emperor's grandson. After Zhu Yuanzhang's death, the emperor's grandson Zhu Yunjiao ascended the throne. After Zhu Yunjiao ascended to the throne, "the domain is strong and the king is weak", and the soldier Shangshu Qi Tai and the TaichangQing Huang Zicheng began to fool Emperor Jianwen into cutting the domain on the grounds that the kings were too powerful and feared that it would be difficult to control. This slashing of the domain directly led to the rebellion of Zhu Di, the King of Yan, in the name of "Qing Junfang", and fought all the way from Beijing to Nanjing, which is known in history as the "Battle of Jingnan".
After Zhu Yunjiao ascended the throne, he did not lose his morality, and cutting the domain was also a matter for his own family, and it was reasonable to say that the common people did not want to start another war, that is to say, Zhu Di's rebellion was not in line with the will of the people. In addition, Zhu Yunjiao, as the central government, held far more troops than the King of Yan, but zhu Di became the only king in history to successfully rebel.
Obviously, Zhu Di did not have an advantage in terms of combat strength and people's hearts, but he let the Ming Dynasty change its master since then, how could Zhu Yunjiao not be able to do Zhu Di?
First, there was a mistake in the order of cutting the clans
In the order of cutting the domain, Qi Tai and Huang Zicheng had different opinions. Qi Tai advocated first getting rid of zhu di, the most powerful Yan king, while Huang Zicheng advocated first getting rid of the faulty king of the clan and gaining public support. Zhu Yunzhao chose Huang Zicheng's plan and successively cut 5 princes, and it was the status quo of these 5 princes that made Zhu Di determined to raise an army, but Zhu Yunzhao did not adopt Qi Tai's plan, giving the King of Yan enough time to prepare.
Second, Zhu Yunjiao's indecisiveness
Before the great war, Zhu Di sent his sons Zhu Gaoxu, Zhu Gaoxu, and Zhu Gaoxuan to Beijing to participate in Zhu Yuanzhang's sacrifice ceremony. Zhu Yunjiao could have held Zhu Di's three sons hostage to contain Zhu Di. But Zhu Yunjiao hesitated again and again, or let the three people go. In addition, after the rebellion of Zhu Di, the so-called "capture of the thief first", Emperor Jianwen explicitly decreed that Zhu Di was not allowed to be harmed, resulting in Zhu Di's repeated desperate situations and final victory in danger, and the Yan soldiers became more and more courageous in the war.
Third, there have been problems in the employment of personnel
When it comes to Zhu Yunjiao's failure to stop Zhu Di, posterity always blames the problem on Li Jinglong, and after the defeat of Zhengba Village and Baigou Village, the army's morale is broken, easy to defend, difficult to attack, and there is enough grain and grass to fight a protracted war, but he continues to entrust him with heavy responsibilities. Li Jinglong's army was defeated and he threw away his 600,000 troops. When Zhu Di's forces invaded the city of Nanjing, Li Jinglong surrendered The city of Kaicheng and Nanjing fell.
Fourth, tactically inappropriate
The advantages and disadvantages of the Yan soldiers and the central army are still very obvious; the Yan soldiers have been holding beiping for many years and have the experience of fighting against the Mongol soldiers outside the country for many years, but they have no choice but to have fewer soldiers; while the central army does not lack people, but in the interior all year round, the opportunity to fight is small, and the experience is not as good as that of the Yan soldiers. The shortcomings of the Yan soldiers should be to consume the other side's living strength as much as possible, regardless of the gains and losses of one city and one place. The tactics of the central government were also exactly the opposite, one city after another, one place after another, and the result was that the army of Zhu Di, the King of Yan, fought more and more, and the more they fought, the stronger they became.
Zhu Yunjiao could not compare with Zhu Di in terms of courage and strategy or experience, and these multiple factors eventually caused Zhu Yunjiao to occupy such a good advantage, but in the end his life and death were unknown.
