Jiang Ji 蔣濟

Jiang Ji 蔣濟 (d. 249 CE), courtesy name Zitong 子通, was a high official of the Wei period 曹魏 (220-265).

He hailed from Ping'a 平阿 in the princedom of Chu 楚 (modern Huaiyuan 懷遠, Anhui) and served the Later Han dynasty 後漢 (25-220 CE) as a local official, the last post being that of governor (taishou 太守) of the commandery of Danyang 丹陽. He then decided to serve the warlord Cao Cao 曹操 and became one of his most trusted advisors. When Cao Cao's son Cao Pi 曹丕 (Emperor Wen of Wei 魏文帝, r. 220-226) assumed the title of emperor, Jiang Ji was appointed eastern leader of the court gentlemen (dong zhonglangjiang 東中郎將), but soon thereafter was made cavalier attendant-in-ordinary (sanji changshi 散騎常侍).

Emperor Ming 魏明帝 (r. 226－239 CE) bestowed upon him the title of Marquis within the Passes (guanneihou 關內侯) and appointed him Capital Protector (zhonghujun 中護軍). Under the next ruler, the Prince of Qi 齊 (r. 239-254), Jiang Ji was made General of the Palace Guard (lingjun jiangjun 領軍將軍), was given the title of Neighbourhood Marquis of Changling 昌陵亭侯, and given the title of Defender-in-chief (taiwei 太尉).

In the fight between the two regents Cao Shuang 曹爽 and Sima Yi 司馬懿, Jiang Ji sided with the latter, and carried out the extermination of Cao Shuang. He was offered the title of Township Marquis of Duxiang 都鄉侯, yet Jiang declined. He died of an illness. His posthumous title was Marquis Jing 昌陵亭景侯.

Jiang Ji is known as the autor of the political treatise Jiangzi wanjilun 蔣子萬機論 (short Wanjilun 萬機論).
