In ancient customs, the inheritance of the throne generally followed the system of primogeniture, but in the Ming Dynasty, such traditional old customs were broken by Zhu Yuanzhang. Zhu Yuanzhang, one of the most legendary emperors in Chinese history, and he was able to ascend to the throne from a poor man, and he had a charm and courage that ordinary people did not have. As we all know, Zhu Yuanzhang gradually withdrew his military power after the establishment of the Ming Dynasty, and in the process Zhu Yuanzhang was a rough man, he did not know how to handle the relationship between kings and subjects, he blindly sent Jinyi guards to monitor hundreds of officials, from which to find the shortcomings of officials, in order to eliminate those generals who had fought for him.
Zhu Yuanzhang's approach made many posterity very confused, why didn't he follow Zhao Kuangyin's example? Rather than using such tactics. Zhu Yuanzhang also has many unfamiliar practices, such as his selection of the heir to the throne, and the general heir to the throne is to select suitable candidates from his sons, but Zhu Yuanzhang extends the heir to the throne to his own imperial grandson. Zhu Yunjiao was the son of the crown prince Zhu Biao, in fact, Zhu Yuanzhang initially cultivated Zhu Biao as the heir to the throne. Zhu Biao is very different from Zhu Yuanzhang, but Zhu Yuanzhang's selection of Zhu Biao is not Zhu Biao's superiority, but Zhu Biao's identity as the eldest son, which can be seen that Zhu Yuanzhang still wanted to follow the traditional custom of the eldest son at the beginning.
Later, zhu Biao suddenly fell ill at the age of 37, and eventually Zhu Biao died, when Zhu Biao's son Zhu Yunjiao attended his funeral, when Zhu Yunjiao fainted due to excessive sadness at the funeral. Zhu Yuanzhang was touched by the actions of this imperial grandson, and Zhu Yuanzhang regarded Zhu Yunjiao as the heir to the imperial throne. In fact, according to Zhu Yunjiao, he was not the eldest grandson of Zhu Yuanzhang, because Zhu Biao also had an eldest son, but this child died prematurely. Zhu Yunjiao was Zhu Biao's second son, but Zhu Yuanzhang missed Zhu Biao too much, so he regarded Zhu Yunjiao as his son.
Later, after Zhu Yuanzhang's death, he left a will to pass the throne to the emperor's grandson. At that time, the princes had great objections to this, especially Zhu Di, who had experienced hundreds of battles, he was the fourth son of Zhu Yuanzhang, according to the custom, after Zhu Biao's death, he was the prince who most wanted to inherit the throne, and Zhu Di had already been in the battlefield when he was young, and he had made great achievements for the establishment of Daming, and if the throne was inherited by him, it was also deserved. However, the throne was now inherited by Zhu Yunjiao, and Zhu Di could only reluctantly accept this fact.
After Zhu Yunxiong ascended the throne, he chose his teacher Huang Zicheng and others as his assistant ministers, and originally Huang Zicheng and Qi Tai were both Figures of the Confucian School. However, after Zhu Yunzhuo ascended the throne, they overthrew the Confucian ideas that had previously taught him, and suggested that Zhu Yunjiao use various means to weaken the real power of the imperial uncles. After Zhu Yunjiao ascended the throne, he abolished and changed many of the systems that Zhu Yuanzhang had left behind before that were unfavorable to the people, but in Zhu Di's view, these changes were blasphemy against his father Zhu Yuanzhang. Under the repeated persuasion of Huang Zicheng and others, Zhu Yunjiao finally adopted a relevant system that weakened the real power of the emperor. Zhu Xu, the King of Zhou, became Zhu Yunjiao's first target, and several other imperial uncles were also suppressed by Zhu Yunjiao in various names.
Zhu Di suddenly realized that the original cowardly Zhu Yunjiao also had a fierce side, so Zhu Di secretly recruited soldiers, and also colluded with the eunuch clique that was attacked by Zhu Yunjiao, and Zhu Di also used means such as pretending to be ill and pretending to be crazy to deceive Zhu Yunjiao, so that Zhu Yunjiao could let down his guard against him. Later, Zhu Di raised an army from northern Yan and led a large army to attack the imperial court in the name of the Qing Emperor's side, Zhu Yunjiao's generals were not opponents of the emperor's uncle Zhu Di, and soon Zhu Di defeated the imperial army, and eventually Zhu Di captured Nanjing, and Zhu Yunjiao also disappeared in a fire.
