Sima Yi

Sima Yi (179 – September 7, 251) was a general and politician of the state of Cao Wei during the Three Kingdoms era of Chinese history. He is perhaps best known for defending Wei from Zhuge Liang's Northern Expeditions. His success and subsequent rise in prominence paved the way for his grandson Sima Yan's founding of the Jin Dynasty, which would eventually bring an end to the Three Kingdoms era. In 265 after the Jin Dynasty was established, Sima Yi was posthumously honored as Emperor Xuan of Jin with the temple name of Gaozu.
