About Jia Sidao
Lived 1213 – 1275 (aged 61). Jia Sidao was a Chinese politician.
Inscription by Jia Sidao and his friends on Lianhua Peak, Near the Lingyin Temple, Hangzhou. The inscription's content says: On the day of the full moon of the tenth month of the Year Dingmao of Xianchun (Autumn 1267), Jia Sidao came to the Lingyin temple for his annual prayer service. Accompanied by Wu Zicong, Shu Yuanzhe, Qiu Fuheng, Yu Xin, Liao Yinzhong, Zhang Ru, Huang Gongshao, and Wang Ting. His son Desheng and grandson Fanshi escorted him. Monk Fazhao, Dening, Shiju and Miaoning also attended this event.
Jia Sidao (August 25, 1213 – October 1275), courtesy name Shixian, was a Chinese government official who served as chancellor of the Southern Song dynasty of China. He was the younger brother of a concubine of Emperor Lizong, who had the special favor of Emperor Duzong. Jia Sidao took part in a land nationalization program in the 1260s and was involved during the Mongol conquest, especially during the Battle of Xiangyang and the siege of Ezhou. He was assassinated by a Song dynasty court-designated sheriff charged with his custody in 1275. In Chinese history, his reputation is on par with Qin Hui's.
Early life Jia Sidao was born in 1213, to Jia She and Lady Hu; Hu was a renounced concubine of Jia She. Jia She died when Jia Sidao was 11. By the time he earned his jinshi at the age of 25 in 1238 AD, his elder sister was already a concubine of the Emperor Lizong with the rank of guifei. According to History of Song, he is reported to have risen to the rank of chancellor because his sister, Lady Jia, was a favored concubine of the Emperor Lizong. In contrast, Jia's reforms offered no compensation; another of Jia's aims was to abolish the hedi policy, and reduce the amount of paper money in circulation, as under the hedi policy, with the government purchasing more grain, they had to issue more paper money, resulting in rising inflation.
During the siege of Ezhou, Jia Sidao's offer to Kublai Khan to partition China was rejected, however due to Mongke's failure of the Yunnan campaign, and a redirection of massive troops to the Ezhou frontier, Kublai decided to offer Jia Sidao a deal that he would return to Karakorum for his kurultai due to the succession dispute with Ariq Böke.
Later, at the Battle of Yihu, Jia Sidao, while leading an army of 130,000, panicked and escaped the battlefield in a small boat. The troops, seeing that their commander had abandoned them, retreated hastily; the result was a defeat whereby the remnants of the Song army were routed, allowing the Mongols to advance on the capital, Lin'an. As a result of this defeat, Jia Sidao was demoted from the post of chancellor.
Death The possibility of executing Jia Sidao for his court failures was hotly debated in Lin'an (now Hangzhou) on the verge of its fall. Dowager Empress Xie objected to this as a cruelty, but issued progressively severe decrees of banishment and property confiscation that included Jia Sidao and his family under the pressure of the public. Ultimately, in 1275, Jia Sidao was assassinated by a court-designated sheriff, Zheng Huchen (郑虎臣), who had been charged with his custody. Whether the execution was court-sanctioned remains unclear.
