Fú Jiān, emperor of the Chinese Di state Former Qin (b. 337)
Fu Jian (Chinese: 苻堅/苻坚; 337–385), courtesy name Yonggu (永固) or Wenyu (文玉), formally Emperor Xuanzhao of (Former) Qin ((前)秦宣昭帝), was an emperor (who, however, used the title "Heavenly King" (Tian Wang) during his reign) of the Di-led Chinese Former Qin dynasty, under whose rule (assisted by his able prime minister Wang Meng) the Former Qin state reached its greatest glory—destroying Former Yan, Former Liang, and Dai and seizing Jin's Yi Province (modern Sichuan and Chongqing), posturing to destroy Jin as well to unite China, until he was repelled at the Battle of Fei River in 383. For a variety of reasons, the Former Qin state soon collapsed after that defeat, and Fu Jian himself was killed by his former subordinate, Yao Chang the founding emperor of Later Qin, in 385.
