The last emperor of the Southern Song Dynasty was Zhao Huan, Emperor Qinzong of the Song Dynasty. Zhao Huan was the third son of Song Taizu Zhao Kuangyin. His mother was Empress Wang. During his reign, the Southern Song Dynasty was invaded by the Jin Dynasty in the north. He took a series of measures to deal with this crisis, including strengthening defense, weakening the power of the prime minister, increasing taxes, etc., but was finally defeated by the Jin Dynasty. After Zhao Huan was captured, he was named "Song Qinzong" by the Jin Dynasty and imprisoned in Bianjing (now Kaifeng City, Henan Province). Later, when the Jin Dynasty was destroyed, Emperor Qinzong of the Song Dynasty was able to return to the country, but he had been placed under house arrest in Lin 'an of the Southern Song Dynasty (now Hangzhou City, Zhejiang Province). The Southern Song government and the Jin Dynasty had always maintained a confrontational relationship, and the fate of Song Qinzong was therefore controversial. It was said that Emperor Qinzong of the Song Dynasty was very lazy and indulged in gambling and playing all day long, causing the state's financial situation to deteriorate extremely. In addition, he had been misled many times by his favorite officials to pay little attention to the internal power struggles of the court. In the end, in the peace negotiations between the Southern Song Dynasty and the Jin Dynasty, Emperor Qinzong of the Song Dynasty was forced to abdicate the throne to Emperor Gaozong of the Song Dynasty and declare the demise of the Southern Song Dynasty. Zhao Huan was one of the more tragic emperors in the history of the Southern Song Dynasty. His experience reflected the shortcomings of the Song political system and the corruption of the ruling group.
