Emperor Wu of Jin (simplified Chinese: 晋武帝; traditional Chinese: 晉武帝; pinyin: Jìn Wǔ Dì; Wade–Giles: Chin Wu-Ti; 236 – 16 May 290), personal name Sima Yan (Chinese: 司馬炎; pinyin: Sīmǎ Yán), courtesy name Anshi (安世), was the grandson of Sima Yi, nephew of Sima Shi and son of Sima Zhao. He became the first emperor of the Jin dynasty after forcing Cao Huan, last emperor of the state of Cao Wei, to abdicate to him. He reigned from 266 to 290, and after conquering the state of Eastern Wu in 280, was the emperor of a reunified China. Emperor Wu was also known for his extravagance and sensuality, especially after the unification of China; legends boasted of his incredible potency among ten thousand concubines.
