Qin Er Shi (230/222 – 207 BC[2]), given nameYing Huhai, was the second emperor of the Chinese Qin dynasty, reigning from 210 to 207 BC. The son of Qin Shi Huang, he was put on the throne by Li Si and Zhao Gao, circumventing his brother Fusu, who had been the designated heir. Upon Huhai's ascension, both Fusu and the popular general Meng Tian were killed on the orders of Li and Zhao, with Qin Er Shi's role in the assassinations remaining uncertain and controversial. A weak ruler, Qin Er Shi's reign was completely dominated by Zhao Gao, who eventually forced him to commit suicide.[3][4] By the time of his death, the Qin Empire's power had lessened so much that his successor Ziying ruled as a king, not emperor.[5]
^Vol.8 of Zizhi Tongjian indicate that Zhao Gao intended to make Ziying emperor in the 9th month of the 3rd year of Huhai's reign. The month corresponds to 16 Oct to 13 Nov 207 BCE in the proleptic Julian calendar. Since Huhai committed suicide just before this event, his death date should be in c. October 207 BCE.
