Jia Chong vs Shang Yang

Jia Chong married a daughter of Sima Zhao, strengthening his ties to the Sima clan. This marriage aligned him with the future Jin dynasty and ensured his political survival after the Cao Wei collapse. It also gave him influence over succession matters.

Jia Chong ordered the assassination of Emperor Cao Mao after the emperor led a coup against Sima Zhao. When Cao Mao attacked Sima Zhao's residence, Jia Chong's troops killed him. This act eliminated the last Cao emperor who resisted Sima control.

Jia Chong was appointed Minister of Works under the Jin dynasty, becoming one of its highest-ranking officials. He played a key role in consolidating Sima Yan's rule and was instrumental in the conquest of Wu, serving as a strategist and administrator.

Shang Yang implemented his first set of Legalist reforms in the Qin state, including the abolition of aristocratic privileges, promotion of agriculture and military merit, and the introduction of a strict legal code. These reforms centralized power and increased state efficiency.

Shang Yang introduced further reforms, including the reorganization of the state into administrative counties, standardization of weights and measures, and the promotion of collective responsibility. These measures strengthened Qin's military and bureaucratic capacity.

Shang Yang led a Qin army to victory against the Wei state at the Battle of Anyi. The victory captured the Wei capital and forced Wei to cede territory, significantly expanding Qin's power and demonstrating the effectiveness of his military reforms.

After the death of Duke Xiao of Qin, Shang Yang was accused of treason by the new ruler, King Huiwen. He attempted to flee but was captured and executed by dismemberment (chariot tearing). His family was also executed, ending his influence.
