Since Empress Sun could not easily let the Jingtai Emperor Zhu Qiyu return the throne to her own son Zhu Qizhen, why did she agree to support Zhu Qiyu as emperor after the "change of Tumu Fort", the situation at that time was very different from the situation in which the Jingtai Emperor Zhu Qiyu was firmly seated on the throne.
Emperor Mingyingzong Zhu Qizhen was the son of Empress Sun, or the eldest son of Emperor Mingxuanzong Zhu Zhanji, he inherited the throne in accordance with the law, he was only 9 years old when he was emperor, his birth mother Sun Shi was honored as empress, and the right and right of the government was the "Three Yangs" cabinet left to him by Emperor Xuanzong of Ming, before the "change of Tumu Fort", Zhu Qizhen basically did not participate in the government, there were three Yangs in his youth, and there was a eunuch Wang Zhen in his youth. The change of Tumu Fort is the shame of Ming Yingzong's life, and even more the shame of the Ming Dynasty. Zhu Qizhen, instigated by the eunuch Wang Zhen, personally conquered Vala and led 200,000 elite Ming troops to be slaughtered by the Wallachian army at Tumu Fort, and Emperor Zhu Qizhen was also taken prisoner of Wallachia.
The Ming Dynasty is quite dangerous, do not think that the Walla also led only 50,000 people and horses, and could not pose a threat to the Ming Dynasty, this is a very wrong concept, the Wallachians do not necessarily subvert the Ming Dynasty, as long as they capture the city of Beijing, the Ming Dynasty can basically stop cooking. The administrative center of the empire was occupied, and the people of the dprk from the emperor to the officials were captured, and the confidence of the people of the world was a devastating blow, and it was almost certain that there were kings of the clan and even powerful people with different surnames who rebelled. The Ming court's immediate priority was to preserve the city of Beijing, and the death or death of the captured emperor Ming Yingzong was a secondary issue. The ming dynasty's life was hanging by a thread, and most of the courtiers suggested moving the capital to Nanjing to avoid the Wala front. Only Yu Qian and a few other loyal ministers stepped forward and held on to Beijing to resist Wallachia.
Holding on to Beijing is very simple, but who will carry this banner is very important, to put it simply, the Ming Dynasty is the old Zhu family's business, the treasurer has been captured, to support this stall, there must be a Zhu family to come out to take charge. The Zhu family was quite important to take charge, which was related to the legal system for the country, and after consulting with many of the main warrior factions and Empress Sun, who was the head of the imperial family at that time, Yu Qian decided to support Zhu Qizhen's younger brother Zhu Qiyu the Prince of Qi as emperor, inherit the legal system of the Ming Dynasty, and carry the banner of resistance to The Wallachians.
Empress Sun, as Zhu Zhanji's wife (deposed the original wife Empress Hu and re-established Sun Shi as the queen), had a certain right to speak in the legal inheritance of the imperial family, but she absolutely had no right to decide, and she hoped that Zhu Qizhen's son Zhu Jianshen would succeed to the throne, and at first because Zhu Jianshen was too young at the time, only a few years old, Yu Qian and other important ministers did not agree. At such a critical juncture, setting up a doll of a few years old to be the emperor is a blow to the confidence of the people of the world to fight against foreign races, and it also makes the kings of various clans suspicious of the important subjects in the dynasty, and the lord is less suspicious of the country, which is the truth.
Sun Shi agreed to the plan of making Zhu Qiyu emperor, and the Jingtai Emperor Zhu Qiyu was also very capable, working with the main war ministers of the DPRK and China to turn the tide, defeating the Wallachian army and preserving the city of Beijing. If Emperor Mingying's Zhu Qizhen did not return, it was estimated that the throne of The Jingtai Emperor Zhu Qiyu would be passed on to his side. The ghost sent the gods, and Zhu Qizhen was sent back by Vala. At this time, everyone is very embarrassed. Since Zhu Qiyu's throne was obtained at an extraordinary time, and the great orthodox emperor Zhu Qizhen returned, why not return it to Zhu Qizhen? There is a question of legal system at stake. Imperial succession is not a simple object, if you want to give, give, if you want to, let go. It is not the ruyi in Empress Sun's hand, who wants to give it to whomever she wants. Since ancient times, the struggle for the throne is the most costly, the most profitable, the most risky thing, no emperor wants to give up the throne plainly, power is the soul of everyone, the emperor is the power of all power, let alone sell it in vain.
The inheritance of the throne is not simply the emperor's own business, which concerns many stakeholders. Zhu Qiyu's throne was related to the interests of the civil officials clique defending Beijing, first of all, they would not easily agree to return the imperial power to Emperor Mingyingzong Zhu Qizhen; although Empress Sun was the co-lord of the imperial family, it was the iron bar of the old ancestor that the harem was not allowed to interfere in politics, and she was even less likely to come forward to let Zhu Qiyu return the throne to her own son. She had that mind, but she didn't have that power.
The most important thing is that Zhu Qiyu himself did not think of returning the throne to his brother Zhu Qizhen at all, and in terms of ability, The shoes of Emperor Mingyingzong Zhu Qizhen to the Jingtai Emperor Zhu Qiyu were not worthy; according to the tradition, since Zhu Qizhen was captured at Tumu Fort, the throne of the Ming Dynasty was passed from the eldest son of Zhu Zhanji to the second son of Shu, and there was no precedent or ancestral system for the return of the throne. Of course, Zhu Qiyu's desire to control power is the most critical, whether it is Empress Sun or Emperor Mingying Zhu Qizhen, it is impossible to let Zhu Qiyu cede the throne to Zhu Qizhen in a normal state.
