The First Year of Duanping: the War, Destiny and Political Situation of the Three Kingdoms of Song, Jin and Mongolia in 1234

This book is a popular history book about the Song Dynasty, which tells the story of the disputes between the Song, Jin and Mongolia Three Kingdoms that occurred in the first year of Duanping (1234) of Emperor Lizong of the Song Dynasty. In 1234, the Battle of Jinmeng, which lasted for twenty-six years, came to an end. On the tenth day of the first lunar month, Mongolia and the Southern Song Dynasty joined forces to conquer Caizhou City, which was besieged by Jin Aizong, and the Jin Dynasty was destroyed. For Mongolia, they finally avenged the bloody vengeance of Bahai Khan being nailed to a wooden donkey by Jin Xizong. Five years ago, Genghis Khan passed away on the eve of the fall of Xixia. Ogedei inherited his throne, fulfilled Genghis Khan's last wish to destroy the wealth, and completed the institutionalization and feudalization of the country at a leaps and bounds. Subsequently, the Mongolian integrated forces prepared to operate the Jin Dynasty's old land, and the remaining Jin Dynasty forces were still entrenched in more than 20 prefectures and prefectures in Shaanxi. The Southern Song Dynasty was finally able to avoid the "shame of Jingkang". The fall of the Jin Dynasty was undoubtedly a great encouragement to the soldiers and civilians of the Southern Song Dynasty, and it also seemed to be an "opportunity for the Central Plains." The Southern Song Dynasty began to prepare for the Northern Expedition. However, the voices within the court were divided as usual, whether it was war or peace, making people confused. The high-spirited Song Lizong made the final decision and decided to send troops to the Northern Expedition to regain the three capitals (Luoyang, Kaifeng, and Yingtian). For the Southern Song Dynasty and Mongolia, the extermination of the Jin Dynasty was not only an act of revenge, but also would bring about drastic changes in the entire East Asian pattern. This must be a critical moment in history that affects the political situation and destiny of the three kingdoms of Song, Jin and Meng.
