In the hearts of many people, Yu Qian is a great hero of the Ming Dynasty, and without him, the Ming Dynasty may have been invaded by The Wallachians long ago. After Emperor Ming Yingzong was reinstated, he not only did not care about his merits and deeds, but instead died of "conspiracy to rebel", and as soon as Yu Qian died, Ming Yingzong was accused of "killing meritorious heroes in vain", and even if he did more good deeds, he would be criticized. If so, why did he kill Yu Qian? There are three reasons for this:
First, embrace Zhu Qiyu
Before Emperor Mingying's expedition to Zhu Qizhen, he ordered Zhu Qiyu the Prince of Qi to oversee the state, and Yu Qian assisted and took charge of military power. But as soon as he was taken captive by Vala, Yu Qian embraced Zhu Qiyu. First, he only let the king oversee the country, and did not make him the "emperor's brother-in-law", and Zhu Qiyu took the throne in this way, which was equivalent to plotting rebellion.
Second, disregard the safety of Ming Yingzong
When Vala took Ming Yingzong away, he only wanted him to become a hostage and come to negotiate terms with the imperial court, who knew that when Vala put forward the conditions, Yu Qian said: "Why show weakness and make the enemy lighter than me." This surprised Wa Lai, and in the end they could not see that they were taking advantage, so they offered to send back Ming Yingzong and ask the imperial court for peace. However, in the eyes of Emperor Ming Yingzong, Yu Qian's actions became disregard for the emperor's safety.
Third, support Zhu Qiyu to depose the crown prince
Zhu Qiyu was able to become emperor, all thanks to Yu Qian, and now Zhu Qiyu wants to abolish the prince, not to mention whether Yu Qian has prevented the abolition of the prince, but in Ming Yingzong's heart, nature and Yu Qian are inseparable. He may even think that this is a conspiracy of Yu Qian and Zhu Qiyu.
These things are connected, from the perspective of Ming Yingzong, Yu Qian is a complete "chaotic thief". First of all, to support Zhu Qiyu, this is equivalent to betraying Ming Yingzong. Secondly, to reject the condition of Vala is to disregard his own safety and want to let himself die in Walla, so that the world is Yu Qian and Zhu Qiyu's. In the end, the crown prince was deposed and Zhu Qiyu's son was made the crown prince, and the whole plan could be described as seamless and natural. In this way, emperor Ming Yingzong was able to do the first, and even future generations did not want to succeed to the throne. Therefore, Ming Yingzong would kill Yu Qian.
