In the middle of the Southern Song Dynasty, the struggle between the main war faction and the main and peace factions became increasingly fierce. Since the failure of the Kaixi Northern Expedition, the powerful minister Shi Miyuan took the opportunity to kill han nongxin, the prime minister of the main war faction, thus holding the Southern Song Dynasty for 26 years. Compared with other Southern Song Dynasty prime ministers, Shi Miyuan was a complete capitulationist, he not only sold the national interests of the Southern Song Dynasty to nothing, but also directly interfered in the succession of the Southern Song Dynasty, from this point of view, he was more excessive than Qin Juniper, so what is going on?
It turned out that when Song Ningzong was on the throne, although he gave birth to 9 sons, but for various reasons, all his own sons died prematurely, so Song Ningzong had to choose the crown prince from his clan relatives, first in 1198 AD, Song Ningzong established Taizu's ninth grandson Zhao Yuan as the crown prince, but it is regrettable that Zhao Ningzong did not become a prince and died of illness in 1220 AD.
In 1221, Emperor Ningzong of Song made the son of King Hui of Yijing crown prince and gave him the name Zhao Hu .) Zhao Hu was a relatively accomplished prince, very dissatisfied with the dictatorship of the chancellor Shi Miyuan, and once wrote to the emperor that Shi Miyuan should be sent to eight thousand miles away. A map was often hung in his palace, and Zhao Hu often pointed to Hainan Island on the wall and said to others: "If I become emperor in the future, I will exile the prime minister to Qiongya (Hainan Island)!" Shi Miyuan was very afraid of this, so he hurriedly gave Zhao Zhu a generous gift, and as a result, Zhao Miyuan took advantage of the wine to smash all the gifts sent by Shi Miyuan.
In this regard, Shi Miyuan was very angry, if in the future after Zhao Hu ascended the throne as emperor, he would definitely not have his own good fruit to eat, so he colluded with Empress Yang and planned to depose the crown prince and establish Zhao Yun as emperor. In 1224, When Emperor Ningzong of Song died of illness, Shi Miyuan and Empress Yang hurriedly sent someone to take Zhao Yun to the palace, and at this time the former crown prince Zhao Hu was still in the dark, and he waited in the palace for a long time but did not wait for the emissary to greet him.
When he went to the court the next day, Zhao Hu found that he was still waiting for the original shift, so he was surprised and said to The Marshal Xia Zhen of the Palace, "How can I stand in this position today?" Xia Zhen said foolishly, "It is not too late to take the throne after the announcement of the will." After a while, Shi Miyuan and Empress Yang announced that the new emperor Zhao Yun was on the throne, and Zhao Hu realized that the throne he had reached had flown, so he was kneeling down with his head pressed in shock.
