Cao Shuang vs Wu Zixu

Cao Shuang was appointed co-regent alongside Sima Yi for the young Emperor Cao Fang. He quickly marginalized Sima Yi, concentrating power in his own hands. His faction promoted Confucian reforms and centralized authority, but alienated many officials.

Sima Yi launched a coup while Cao Shuang accompanied Emperor Cao Fang to the Gaoping Tombs. Sima Yi seized control of Luoyang, accusing Cao Shuang of usurping power. Cao Shuang surrendered in exchange for promises of safety, but was later executed.

After surrendering, Cao Shuang and his entire faction were executed by Sima Yi on charges of treason. This purge eliminated the Cao family's political influence and solidified Sima Yi's control over Wei, paving the way for the Sima clan's eventual usurpation.

Wu Zixu orchestrated the assassination of King Liao of Wu, placing Prince Guang on the throne as King Helu. This event allowed Helu to become king and Wu Zixu to serve as a key strategist, setting the stage for Wu's rise.

Wu Zixu, as strategist for King Helu, led the Wu army in a successful invasion of Chu. The Wu forces captured the Chu capital Ying, forcing King Zhao of Chu to flee. This victory was a major achievement for Wu.

After capturing the Chu capital, Wu Zixu exhumed the corpse of King Ping of Chu, who had killed his father and brother, and flogged it. This act of personal vengeance was widely condemned and damaged Wu's reputation.

King Fuchai of Wu, suspicious of Wu Zixu's loyalty, ordered him to commit suicide. Wu Zixu complied, but prophesied that Wu would fall. His death weakened Wu's leadership, and Wu was later conquered by Yue.
