Wei regent whose ambition was transparent to all who saw him.
Compare Sima Zhao with another historical figure:
The Wei general Zhuge Dan rebelled in Shouchun against Sima Zhao's regency. Sima Zhao led a massive army to besiege the city. After a year-long siege, Shouchun fell, and Zhuge Dan was executed, solidifying Sima Zhao's control over Wei.
The Wei emperor Cao Mao attempted a coup against Sima Zhao but was killed by Sima Zhao's subordinate Jia Chong. Sima Zhao then installed Cao Huan as a puppet emperor, further demonstrating his control over the imperial court.
Sima Zhao ordered a three-pronged invasion of Shu Han, led by Deng Ai, Zhong Hui, and Zhuge Xu. Deng Ai's surprise march through the Yinping mountains forced the surrender of Shu. This conquest eliminated the last major rival state and paved the way for the Jin dynasty.
Sima Zhao died in 265 without formally usurping the throne. His son Sima Yan forced the abdication of Cao Huan and founded the Jin dynasty. Sima Zhao was posthumously honored as Emperor Wen of Jin, recognizing his role as the dynasty's founder.
