The Blue Jade Party case was one of the four major cases in the early Ming Dynasty, and it was also another large-scale massacre of a meritorious general by Zhu Yuanzhang after the Hu Weiyong case. Regarding the cause of this matter, the mainstream view has always been that The pride and indulgence of Blue Jade himself and Zhu Yuanzhang's paving the way for the crown prince Zhu Biao were the main reasons, but in fact, behind this matter, there is one person who cannot be ignored, he is the later Yongle Emperor Zhu Di.
In this political struggle to exclude dissidents, Zhu Di was not the sharpshooter in front of the stage, but the sharpener behind the scenes.
As early as zhu Yuanzhang's lifetime, Zhu Di had already exposed his wolf ambitions to covet the throne. Especially after the senior monk Yao Guangxiao stayed in the Yan King's Mansion, his deeds gradually deviated, and he was always speaking in a flat voice.
And all this was insightfully perceived by The Confidant Minister Lan Yu, whom Crown Prince Zhu Biao relied on. He was the uncle of the crown princess, and naturally he would always be on the side of the prince. That is to say, there is an irreconcilable contradiction between Zhu Di and Zhu Biao and Lan Yu.
But before Zhu Yuanzhang's death, Zhu Di always hid his ambitions well, Taoguang was obscure and silent, and he was very respectful in front of the crown prince Zhu Biao, and he was also very humble to other brothers.
In the first years of Zhu Di's reign in Beiping, the military affairs in the north were presided over by his father-in-law Xu Da, who died of illness and was replaced by the generals Feng Sheng and Lan Yu. Neither of these two people nor Zhu Di were allies in the same trench, and Zhu Di would naturally think of getting rid of them quickly!
Twenty years after Hongwu was defeated by Feng Sheng, after Feng Sheng's conquest of Meng Yuan's great victory, someone suddenly accused him of secretly hiding good horses, which made Zhu Yuanzhang furious, and immediately ordered that his great general seal be taken away, and from then on Feng Sheng no longer controlled the army in his hands, and later because of a private meeting with his son-in-law Zhu Xu, the King of Zhou, which led to rumors, he was directly killed by Zhu Yuanzhang.
Although the history books do not directly state who the whistleblower is, from the perspective of who is the profiteer, it is very likely that Zhu Di has been playing a ghost behind his back!
As for Blue Jade, after Hongwu was worshipped as a great general for twenty years, he once used a good horse to flatter Zhu Di, but he was hit by a blow, and the two were resentful. Lan Yu secretly told Crown Prince Zhu that King Yin of Yan had a disobedient heart.
However, soon the crown prince Zhu Biao died of illness, and Zhu Di took the opportunity to go to the capital and told Zhu Yuanzhang that the princes were arrogant and lawless, and they were afraid that they would not be able to lose their tails. Zhu Yuanzhang was once again suspicious of the heroes.
At that time, Sapphire was arrogant and lawless because of its great merits. At first, Zhu Yuanzhang remembered that he had a good relationship with the crown prince Zhu Biao, so he only blamed it.
However, soon after, someone reported that Blue Jade had rebelled, and eventually he was ordered by Zhu Yuanzhang to be hunted down and killed, and more than 15,000 people were killed from the gonghou to the civil and military officials. Behind this is also a high probability that Zhu Di is playing a ghost, he took advantage of Zhu Yuanzhang's psychology of being jealous of the heroes, and constantly agitated next to him, which eventually led to the occurrence of this tragedy.
