Shi Siming

Shi Siming (Chinese: 史思明) (19th day of the 1st month, 703? – 18 April 761), or Shi Sugan (史窣干), was a Chinese military general, monarch, and politician during the Tang dynasty who followed his childhood friend An Lushan in rebelling against Tang, and who later succeeded An Lushan's son An Qingxu as emperor of the Yan state that An Lushan established.

It is not known when Shi Sugan was born, other than that he was born one day before his friend An Lushan and that they grew up together. He was of Tujue extraction, and was said to be thin with smooth skin, with an impatient disposition. After both he and An grew up, they were both known for their bravery. However, he was poor and of low social station, and was looked down by the people of his locale. However, a Lady Xin, a daughter of local gentry, insisted on marrying him despite her family's opposition, and she was eventually successful in doing so.

In spring 761, Shi Siming began another attempt to attack Shan Prefecture, wanting to attack Chang'an. He had Shi Chaoyi serve as his forward commander, but Shi Chaoyi was repeatedly repelled by the Tang general Wei Boyu (衛伯玉). Shi Siming was angered by Shi Chaoyi's failures and considered punishing him and the generals below him. On 18 April, Shi Siming ordered Shi Chaoyi to build a triangular fort with a hill as its side, to store food supplies, and ordered that it be completed in one day. Near the end of the day, Shi Chaoyi had completed it, but had not plastered the walls with mud, when Shi Siming arrived and rebuked him for not applying mud. He ordered his own servants to stay and watch the plastering. He then angrily stated, "After I capture Shan Prefecture, I will kill you, thief!" That night, Shi Chaoyi's subordinates Luo Yue (駱悅) and Cai Wenjing (蔡文景) warned him that he was in dire straits—and that if he refused to take action to depose Shi Siming, they would defect to Tang. Shi Chaoyi agreed to take action, and Luo persuaded Shi Siming's guard commander General Cao (personal name lost to history) to agree with the plot. That night, Luo led 300 soldiers and ambushed Shi Siming, binding him and then beginning a return to Luoyang with the troops. On the way back to Luoyang, Luo feared that someone might try to rescue Shi Siming, and so strangled him to death.

Shi Chaoyi enthroned as the new emperor of Yan. He was eventually defeated by Tang forces and committed suicide in 763.
