Considering that Zhu Yunwen was still young, Zhu Yuanzhang did not hesitate to kill the hero in his later years, thinking that this would make Zhu Yunwen sit on the throne. Unexpectedly, Rebecca, Zhou Wang, Wang Qi and Daiwang became more and more powerful. In order to solve the problem that Zhu Yunwen couldn't sleep well, shortly after he ascended the throne, Zhu Yunwen conspired with his confidant minister to separate the vassals.
It wasn't long before Zhu Yunwen implemented the policy of reducing vassals. In a short period of one year, Zhou, Qi, Xiang, Dai and Min were abolished successively. At the same time, Judy, the prince guarding Beiping, was also restricted by the court. In July of the first year of Wen Jian (1399), Judy, the prince of Yan, was forced to rebel in Beiping in the name of "the frontier of the Qing army" and vowed to go to war. As a result, as we all know, Zhu Yunwen was defeated and fled, and his whereabouts were unknown, but Judy succeeded in usurping the throne and seizing power and became the new emperor.
The reason lies not only in Zhu Yunwen's indecision, but also in Zhu Yunwen's failure to use 300,000 troops on the southwest border. In order to prevent future domestic rebellion, Zhu Yuanzhang left Zhu Yunwen and guarded the southwest with 300,000 imperial guards. Then why didn't Zhu Yunwen use them? Please listen to Bian Xiao in detail.
This army was named Mujiajun. The first leader was Mu Ying, Zhu Yuanzhang's adopted son. Mu Ying was born in poverty, and was displaced from place to place since childhood. He was adopted by Zhu Yuanzhang at the age of eight and fought with Zhu Yuanzhang at the age of twelve. During this period, he made many contributions, which won Zhu Yuanzhang's esteem. Later, Zhu Yuanzhang sent him to guard Yunnan, and Mu Ying was even more loyal and devoted to guarding Yunnan. Although Mu Ying was dead when Zhu Yunwen acceded to the throne, and Mu Sheng, the second son of Mu Ying, was the leader of Mu Jiajun at that time, the powerful fighting capacity of Mu Jiajun was not weakened. Some people say that if Zhu Yunwen called this army in the battle of Jingnan, Judy would have no chance to claim the throne. Then why didn't Zhu Yunwen use this army?
According to most people's analysis, it's not that Zhu Yunwen didn't want to use the Mujiajun, but that he didn't have time to recruit troops. At that time, Judy was on a roll and soon entered Nanjing. It's too late for Zhu Yunwen to escape. Where did he get the time to call the army? Later, it was speculated that he did not die, but became a monk and fled to the southwest, where he lived under the protection of the Mu family for decades. However, this statement is only speculation, and whether it is true or not remains to be verified.
