in China and the sixth emperor of the Southern Song dynasty. He was a nephew of his predecessor,
, and reigned from 1264 until his death in 1274.
Early life
Emperor Duzong's mother Huang Dingxi wanted to have an abortion because she thought she was of low social status so she took drugs in an futile attempt to abort Duzong. Duzong was born anyway but the drugs affected him in many ways such as that his intelligence was lower than an average person, his hand and feet were soft; using them in an awkward fashion and he couldn't even speak until he was seven years old. He was Yurui's only son. Like his uncle Zhao Yun, he lived in Shaoxing.
Discovery
Duzong was discovered by his paternal uncle Zhao Yun, better known as Emperor Lizong in 1253, who was sonless and therefore had no heirs so to compensate, adopted Duzong and designated him crown prince in 1260, an action historians still view as confusing. Emperor Lizong died in 1264 and Emperor Duzong then ascended the throne.
Reign
Emperor Duzong's reign was plagued with rebellions, warfare and corruption in his court; many officials accused the chancellor Jia Sidao of corruption but Duzong trusted Jia Sidao who Duzong honoured by bowing down to Jia even calling him "teacher" and according to anecdotes, when Jia was considering resigning, Duzong knelt down in tears begging Jia to remain in office.
Emperor Duzong ignored his duties and instead delegated all state and military affairs to the hands of Jia Sidao; the emperor instead indulged in drinking, women, and lived in opulence. To make things even worse, Duzong』s intelligence was lower than a normal person and he was often depressed. At first, he told the officials to be straightforward and tell him the problems in the countries, but this was all an act. Soon, he completely neglected his duties. Furthermore, he had a very high sexual appetite. Under Song laws, any woman who had sexual relations with the emperor had to pay respects to the emperor every morning. At one point, there were as many as 30 women paying their respects to Emperor Duzong in one morning. Duzong also gave official documents to four of his most favored women.
Mongol Invasion
The Mongols had spent decades harassing the Song Empire's borders and were on the verge of conquering the whole of China. Emperor Duzong however, ignored this problem instead choosing to drink and indulging in sex because when Duzong heard that Xiangyang was being besieged by Mongol troops, Duzong asked Jia Sidao "I hear that Xiangyang had been besieged by the Yuan troops for several years. Is this true?" in which Jia said in all seriousness "Well, I haven't heard such a thing." Duzong replied with "A palace maid told me this."
Siege of Xiangyang
Lu Wenhuan sent a messenger to Emperor Duzong, to request immediate reinforcements to defend Xiangyang. The messenger successfully got by the Yuan forts and reached the emperor but upon hearing the effectiveness of these new trebuchets, the emperor considered Xiangyang lost and did not send reinforcements. The decisive Battle of Xiangyang was fought in 1274 when the Mongols succeeded in capturing and destroying the last Song stronghold. The loss of Xiangyang sealed the fate of the Song dynasty and the news of its capture was deliberately hidden from Emperor Duzong by Jia Sidao.
Death
Emperor Duzong died shortly thereafter from overindulgence in wine but Richard Davis and other sources claim that, Duzong died suddenly from a severe negligence of a Palace Doctor. In any case, he was succeeded by his sixth son, Zhao Xian (Emperor Gong), who was then only four years old. Although Emperor Duzong was technically not the last emperor of the Song dynasty, historians see him as the last Song emperor who could have made decisions that would've significantly halted or even prevented the fall of the dynasty.
Emperor Duzong was buried in the Yongshao Mausoleum on January 1275.
