Overview
Zhuge Jin (174 – July or August 241), courtesy name Ziyu, was a Chinese military general and politician of the state of Eastern Wu during the Three Kingdoms period of China. Born in the late Eastern Han dynasty, Zhuge Jin started his career in the 200s as an official under the warlord Sun Quan, who later became the founding emperor of Eastern Wu in the Three Kingdoms period. In 215, he served as Sun Quan's representative in a territorial dispute over southern Jing Province between Sun Quan and his ally, Liu Bei. In 219, he joined Sun Quan's general Lü Meng in an invasion of Liu Bei's territories in Jing Province after Sun Quan broke the Sun–Liu alliance. He was subsequently appointed as a general and commandery administrator. Before the Battle of Xiaoting of 221–222, Zhuge Jin attempted to dissuade Liu Bei from going to war with Sun Quan but was unsuccessful. The battle ultimately concluded with victory for Sun Quan's side; both sides made peace later and reestablished an alliance between the Eastern Wu and Shu Han states against their rival state, Cao Wei. From 222 until his death in 241, despite being rather incompetent in military affairs, Zhuge Jin served as one of Eastern Wu's top generals and participated in some battles against Cao Wei forces.
Although Zhuge Jin was not as brilliant in statecraft and military strategy as his more famous brother Zhuge Liang, he was known throughout his life for his virtuous character. He had a reputation for conducting himself with grace and decorum, and for being thoughtful, magnanimous and tactful. In return, he gained Sun Quan's trust, and Sun Quan never questioned his loyalty towards him. Zhuge Jin was also known for helping to mediate conflicts between Sun Quan and his subjects, including Zhu Zhi and Yu Fan.
Family background
Zhuge Jin's ancestral home (and probably birthplace too) was in Yangdu County, Langya Commandery, which is located in present-day Yinan County or Yishui County, Shandong. There are two other accounts of his ancestral origins in the Wu Shu and Fengsu Tong.
The Wu Shu recorded that his ancestral family name was actually Ge and his ancestors were originally from Zhu County (諸縣; southwest of present-day Zhucheng, Shandong) before they settled in Yangdu County. As there was already another Ge family in Yangdu County before they came, the locals referred to the newcomers as the Zhuge – combining Zhu (County) and Ge – to distinguish them from the other Ge family.
