Zhuge Ke (203 – November or December 253), courtesy name Yuanxun (元逊), was a Chinese military general and politician of the state of Eastern Wu during the Three Kingdoms period of China. He was the eldest son of Zhuge Jin, a military general who served under Wu's founding emperor, Sun Quan. After Sun Quan's death in 252, Zhuge Ke served as regent for Sun Quan's son and successor, Sun Liang, but the regency proved to be militarily disastrous due to Zhuge Ke's aggressive foreign policy towards Wu's rival state, Cao Wei. In 253, he was ousted from power in a coup d'état and killed along with his family. Early life and career In 221, when the Wu king Sun Quan designated his son Sun Deng as crown prince, he set up a staff for the crown prince composed of the sons of key officials in his government or other well-known younger members of the administration. The four most prominent ones were Zhuge Ke (Zhuge Jin's son), Zhang Xiu (Zhang Zhao's son), Gu Tan (Gu Yong's grandson) and Chen Biao (Chen Wu's son). Sun Deng treated the four of them as his close friends and they served as his advisers. When he ordered his secretary Hu Zong () to write a commentary on four of his advisers in 229, Hu Zong wrote that Zhuge Ke was the most skillful and intelligent of his generation. While this might have been true, Zhuge Ke was also known for being reckless – a negative trait that his father Zhuge Jin repeatedly chided him for. On one occasion, Zhuge Jin observed, "This child will either bring great honour to my household or destroy it." After Sun Quan declared himself emperor in 229 and again designated Sun Deng as his crown prince, the four attendants were promoted to commandants under various titles; Zhuge Ke continued playing a supporting role to Sun Deng. Among his four attendants, Sun Deng favoured and trusted Zhuge Ke and Gu Tan the most, and he regarded them more highly than others such as Fan Shen (范慎), Xie Jing (謝景) and Yang Hui (羊徽). After Hu Zong made his commentary public, Yang Dao (羊衜) commented to Hu in private on the four's shortcomings; Yang's criticism of Zhuge Ke was that "Yuanxun (Zhuge's courtesy name) is talented but neglectful." Later, Yang's criticism of the four became known to them, estranging them from Yang.
