Sima Zhao (onyomi: Shiba Shō) is Sima Yi and Zhang Chunhua's second son, Sima Shi's younger brother, and Wang Yuanji's husband. Using the foundations laid by his predecessors and his ingenuity, he extended the Sima family influence to gain the people's favor by quelling several civil rebellions. When he was in power, Wu's armies failed to penetrate his formations and Shu surrendered. His high esteem in the imperial court helped his son, Sima Yan, later establish the Jin Dynasty.
