The western Mongolian Warat gradually became stronger and more often violated the borders of the Ming Dynasty, and the leader of Warat also led the army south to conquer the Ming Dynasty, and Wang Zhen instigated the Ming Yingzong to gather an army of 500,000 to drive the expedition in person. After the army left Beijing, the soldiers were short of food and tired, and the army arrived in Datong in early August.

The returning division came to the Tumu Fort, where they were overtaken by the Warat army, more than half of the soldiers were killed and wounded, and more than 100 of the retinue ministers were killed. Yingzong broke through the siege and was captured, Wang Zhen was killed by the general Fan Zhong, known as the civil and engineering changes, which was the turning point of the Ming Dynasty from prosperity to decline.

Yu Qian, the squire of the military department, supported Dai Yingzong's younger brother Zhu Qiyu to ascend the throne, that is, the Ming Dynasty, and the year name Jingtai. Yu Qian was promoted to the secretary of the military department, and decided to stick to Beijing, rectify the border defense and actively prepare for war, and then the troops of Zhili, Henan, Shandong and other places arrived one after another.

In October of the same year, the Wara army approached the city of Beijing, and also placed Ming Yingzong in the Tuguan outside the Desheng Gate. Yu Qian led the Ming army to resist bravely, repeatedly broke the Wara army, and also led the army to retreat, the Ming Dynasty won the victory in the defense of Beijing, Yu Qian tried to eliminate public opinion, stepped up the consolidation of national defense, refused to sue for peace, and repelled the many invasions of Warat in the following year.

also released Yingzong first, but Daizong was unwilling to send an envoy to welcome him because of the imperial power problem, and then trapped Yingzong under house arrest in Chonghua Palace, and deposed the crown prince Zhu Jianshen, and set up his son Zhu Jianji as the crown prince. Soon Zhu Jianji died of illness, and Daizong refused to establish Zhu Jianshen as the prince again, as if he had the intention of seizing justice, and Yingzong and Daizong were seriously opposed.

Shi Heng, Xu Youzhen, Cao Jixiang and others allied to support the restoration of Yingzong, and launched a coup d'état when Ming Dynasty Zong was seriously ill. Xu Youzhen led the army into the Forbidden City, Shi Heng and others occupied Donghua Gate, established Yingzong in Fengtian Temple, and changed Yuan Tianshun. They degraded Ming Dynasty Zong as the king of Cheng, and arrested and died in Qian and the university scholar Wang Wen, which is known as the change of seizing the door.

After the restoration of Ming Yingzong, there was a slight new policy, abolishing the martyrdom restored from Ming Taizu. Later, Xu Youzhen was exiled due to an internal coup, Shi Heng, Cao Jixiang and others were killed due to Cao Shi's rebellion, and Li Xian and other virtuous ministers were appointed to govern the country.

Zhu Qiyu of the Ming Dynasty, known as Emperor Jingtai in history, was the second son of Emperor Xuanzong. Zhu Qiyu's biological mother was originally a maid in the mansion of the King of Han, and this King of Han was Zhu Gaoxu, the second son of the famous Yongle Emperor. In the Xuande Dynasty, Emperor Xuanzong used troops against his uncle Zhu Gaoxu, the king of Han, and captured Zhu Gaoxu's father and son, and the female dependents of the Han palace were enslaved in the harem.

On the way back to Beijing, Emperor Xuanzong met Wu, a maid of the Han Palace, and was deeply moved by Wu's beauty and intelligence, so Wu was able to accompany Emperor Xuanzong until he returned to Beijing. After returning to Beijing, due to the obstruction of feudal etiquette, Wu as a sinner could not be named a concubine, so Emperor Xuanzong arranged her in a large mansion close to the palace wall, and often lucky, and finally Wu's beads were secretly knotted, and gave birth to a second son for Xuanzong, named Zhu Qiyu, who was later Emperor Jingtai. Wu was also named a virtuous concubine because of this, but continued to live outside the palace.

In the eighth year of Xuande, Emperor Xuande was seriously ill, and sent someone to summon Zhu Qiyu's mother and son into the palace, and entrusted his mother, Empress Dowager Zhang, to treat Zhu Qiyu's mother and son well. Due to the emperor's funeral, no one cared about the life history of Wu's mother and son, so they were accepted by everyone. Empress Sun did not break her promise, and soon named Zhu Qiyu as the king, and built a palace for their mother and son to live in.

Originally, the mother and son of King Cheng could spend their lives peacefully, but the wolf smoke of Tumubao changed their lives, first King Cheng was ordered to serve as a prisoner during the imperial expedition, and later because Yingzong was captured, the prince Zhu Jianshen was only two years old, and there was no long monarch in the country, so King Zhu Qiyu was pushed to the forefront, and under the instruction of the Empress Dowager Zhang, King Cheng inherited the throne, and respected Yingzong as the emperor, and established Yingzong's eldest son Zhu Jianshen as the prince.

As early as when Zhu Qiyu served as the superintendent, a controversy broke out about moving south, and Xu Youzhen, the attendant of the Hanlin Academy, first proposed the southward move according to the changes in the heavens, and was supported by some timid ministers, but because the ancestral temple and mausoleum were in Beijing, Yu Qian immediately vetoed his proposal and got Zhu Qiyu's support.

Zhu Qiyu admired Yu Qian's ability and courage very much, and Yu Qian also appreciated the young man's quick decision, and the two of them admired each other in the depths of their hearts. The Wumen bloodshed that happened immediately deepened the feelings between the two.

Emperor Yingzong favored the eunuch Wang Zhen, and made the whole court miserable, and the ministers were not conducive to Wang Zhen, either death or depreciation, and a torrent was already brewing in the hearts of the ministers, and finally Yingzong was captured, Wang Zhen was killed, and the grievances of the ministers were poured out, and the ministers knelt at the noon gate and cried, asking King Cheng to punish Wang Zhen's henchmen. At this time, Wang Zhen's sworn friend Jinyi Wei commanded Ma Shun to come out to block, and was immediately killed by the angry ministers.

Seeing this, King Cheng was afraid of a mutiny and was about to flee, but at this time Yu Qian stood up, he grabbed King Cheng's sleeve, and explained to King Cheng that the minister's door was not for King Cheng, as long as King Cheng could punish Wang Zhen's henchmen, the ministers were willing to assist King Cheng for the great cause. So Zhu Qiyu ordered to bring out the two Wang Zhen's dead friends in the palace and hand them over to the ministers, who were also killed on the spot by the ministers, which shows the depth of Wang Zhen's resentment.

After Emperor Jingtai ascended the throne, many loyal people who were excluded by Wang Zhen were able to return to the temple, and the rule of officials was new, and at the same time, under the command of Yu Qian, the preparations for the defense of the capital began, and the grain of Tongzhou was rushed into Beijing, and the fortifications around the capital were reinforced, and Yu Qian also personally organized a new army, and released Shi Heng to participate in the battle.

At the same time, Emperor Jingtai issued a clear edict that the border guards were not allowed to contact with Yexian privately, so that the plan to use Yingzong to defraud the Ming Dynasty of property and the city failed, so he was angry and led a large number of Wara cavalry to the capital overwhelmingly.

Due to Yu Qian's very thorough preparation before the war, the unprecedented unity of the army and the people in Beijing, and the courage of the leading generals and commanders, they finally dealt a heavy blow to the Wara cavalry outside Beijing, and had to retreat to the grassland, and the stormy Ming regime finally stabilized after this battle. The politics of the Jingtai Dynasty should be said to be relatively clear compared with the Orthodox Dynasty, but Emperor Jingtai made a major mistake in dealing with the issue of Yingzong and the crown prince, which also led to his later tragic end.

After Emperor Jingtai sat on the throne, he made the mistake of Song Gaozong and was unwilling to welcome the emperor back to Beijing, for fear that it would affect his status, and therefore had some dirty things with the courtiers. At this time, it was Yu Qian who stood up, he promised that the emperor's return would not affect the emperor's position, and hoped that the emperor could send an envoy to meet the emperor, and Emperor Jingtai was finally convinced, but he only sent an envoy to inquire about the news, and did not offer to greet him.

Who knew that the envoy Yang Shan sent to adapt to the situation, and did not hesitate to sell his property to bribe his cronies, and actually welcomed the emperor back. The raw rice was cooked and cooked, and Emperor Jingtai had no choice but to accept this fact, but even so, in terms of the etiquette of greeting, Emperor Jingtai also reduced and reduced, welcomed Yingzong back to Beijing, and placed him under house arrest in Nangong. In dealing with the issue of Yingzong's return, Emperor Jingtai showed too narrow-mindedness, which was also the biggest stain on his life.

After the return of Yingzong, Emperor Jingtai sent people to strictly guard it, and sure enough, as Yu Qian said, the return of Yingzong did not affect the throne of Emperor Jingtai. But Emperor Jingtai was not satisfied, he not only wanted to be the emperor himself, but also hoped that his son Zhu Jianji could replace Zhu Jianshen, the crown prince of Yingzong, as the legitimate heir to the throne, so he single-handedly directed the farce of bribing the courtiers.

Emperor Jingtai instructed the eunuchs to bribe the important ministers at that time, hoping that they would stand on their side on the issue of rebuilding the prince, but the courtiers were unwilling to openly oppose Emperor Jingtai, so they had to turn a blind eye to this matter. In this way, the crown prince Zhu Jianshen was deposed as the king of Yi, and Zhu Jianji, the son of Emperor Jingtai, was made the crown prince.

Who knew that the heavens betrayed people's wishes, Zhu Jianji died early, and Emperor Jingtai was also hit hard mentally because of this, but fortunately, Emperor Jingtai was still in the prime of life, and the problem of heirs did not have to worry very much for him. In the blink of an eye, it was the eighth year of Jingtai, Emperor Jingtai suddenly fell seriously ill, and the issue of building a reserve became a hot issue and was put on the court, but the opinions of the ministers were not unanimous, some advocated the restoration of the king of Yi, Zhu Jianshen, and some advocated the establishment of the king of Xiang.

Suddenly, the inner palace came to the news that Emperor Jingtai's illness was improving, so the ministers were ready to go to the court the next day to discuss with Emperor Jingtai, but Emperor Jingtai recovered from a serious illness, and fell asleep soon after getting up the next morning, which changed Emperor Jingtai's life, changed the fate of the Ming Dynasty, and changed the direction of the wheel of history.

It turned out that Emperor Jingtai was seriously ill, but the question of the heir had not yet been determined, and the ministers decided to give advice to the emperor the next day, asking the emperor to establish a prince as soon as possible. Who knew that on this night, there was a change that shocked China, and it turned out that the Marquis of the Five Qing Dynasty, Shi Heng, Xu Youzhen, and the eunuch Cao Jixiang conspired to help Yingzong restore, hoping to soar after success.

Shi Heng turned out to be Yu Qian's subordinate, fought bravely, and made meritorious contributions in the defense of Beijing, Yu Qian recommended him as the commander-in-chief of the Beijing Division, and soon he was promoted to the rank of Marquis. Shi Heng was grateful to Dade and always wanted to give Yu Qian a reward, so he wrote to Emperor Jingtai and asked for the promotion of Yu Qian's son, and Emperor Jingtai agreed to Shi Heng's request.

Unexpectedly, after Yu Qian learned about this, he was very angry, and in front of the ministers, he publicly reprimanded Shi Heng's flattery, Shi Heng was annoyed and angry, held a grudge, and always wanted to wait for an opportunity to retaliate. Coincidentally, at that time, there was a war report from the north that Wara harassed the border, so Shi Heng took the opportunity to transfer troops into the city in the name of protecting the safety of the capital, at this time, suddenly the sky was covered with dark clouds, and he couldn't see his five fingers, everyone thought that they were punished by heaven, and they were very afraid, Xu Youzhen stood up and persuaded everyone not to retreat, and everyone continued to move forward, and entered the imperial city smoothly, and went straight to Nangong.

Shi Heng sent someone to break open the palace gate and asked Yingzong to ascend, at this time, the dark clouds suddenly dispersed, the moon and stars were scarce, and the morale of everyone was unprecedentedly high, and Yingzong went straight to Ouchi. The guards at the door wanted to stop it, but at this time Yingzong stood up and showed his identity, and the soldiers guarding the door were dumbfounded, and everyone entered the palace without blood, and came to the Fengxian Hall where the emperor held a court meeting, and helped Yingzong to the throne.

At this time, it was already slightly bright, and the courtiers were already waiting outside the noon gate to prepare for the court, and when they heard the bells and drums ringing in unison, everyone walked into the dedication hall in order, but everything in front of them made them dumbfounded, and the emperor on the throne was no longer Emperor Jingtai, but the orthodox emperor eight years ago. When everyone was hesitating, Xu Youzhen stood up and shouted that the emperor had been restored, and when the courtiers saw this, they had to kneel down and shout long live, and Yingzong regained the throne in this way.

Emperor Jingtai was freshening up in the harem, and after hearing the news, he almost collapsed to the ground, knowing that everything was over. After the restoration of Yingzong, the Yuan Tianshun was changed, and Emperor Jingtai died a month later and was buried in Xishan, Beijing as a prince. Under the strong persuasion of Shi Heng and Cao Jixiang, Yingzong killed Yu Qian, the commander-in-chief of the defense of Beijing, which was another big stain on Yingzong's life after the Tumubao Change.

However, the politics of the Tianshun Dynasty were much clearer than those of the Orthodox Dynasty. Yingzong appointed Li Xian, Wang Ao and other virtuous ministers, and successively pacified the Shi and Cao rebellions, and the society still moved forward. Yingzong should also be regarded as a generation of benevolent monarchs, he released the son of Emperor Jianwen, a Jianshu who had been imprisoned since the Yongle Dynasty, restored the title of Empress Hu of the Xuande Dynasty, and issued an order to stop the burial of concubines after the death of the emperor.

In the eighth year of Tianshun, Emperor Yingzong died of illness at the age of Chinese New Year's Eve, and the crown prince Zhu Jianshen inherited the position, and Emperor Yingzong completed his complicated life path. When Yingzong went north, he ordered his younger brother Zhu Qiyu to guard Beijing as a prisoner, and after the news of the defeat of Tumubao came, under the support of the ministers, the empress dowager ordered Zhu Qiyu to ascend the throne and change the Yuan Jingtai.

Emperor Jingtai confiscated the house of the culprit Wang Zhen, and the whole clan was punished, and at this time he also led a large army to surround Beijing, and Zhu Qiyu appointed Yu Qian as the secretary of the military department to command the defense of Beijing. At that time, the soldiers of the tile spur army were very sharp, and Xu Hui said that the capital should be moved south to avoid its edge, which was refuted by Yu Qian. Yu Qian was dressed in military uniform, went to the front line in person, supervised the general battle, and repelled the Mongol soldiers. Zhu Qiyu sat firmly on the throne of the emperor, and ordered people to start building a mausoleum for himself in the Ming Tombs.

As soon as Zhu Qizhen ascended the throne of the emperor and settled the ministers, he sent the eunuch Jiang An to strangle the Jingtai Emperor Zhu Qiyu to death in the palace and cancel his imperial title. For this younger brother, who had indeed been the emperor for seven years, Zhu Qizhen did not allow him to be buried in the emperor's mausoleum, and abolished the mausoleum that he had pre-camped during his lifetime.

There is a place called Jingtaiwa in the Ming Tombs, which is the mausoleum that Emperor Jingtai pre-arranged for himself. Zhu Qiyu was buried with the gift of the prince, and the burial place was in Jinshankou in the north of Yuquan Mountain.
