Fu Jian, Chinese emperor (born 337)
Fu Jian (337–385)
Fu Jian, courtesy name Yonggu (永固) or Wenyu (文玉), also known by his posthumous name as the Emperor Xuanzhao of Former Qin (前秦宣昭帝), was the third monarch of the Di-led Chinese Former Qin dynasty, ruling as Heavenly King. Under his reign, the Former Qin unified Northern China by conquering the Former Yan, Chouchi, Former Liang, and Dai, as well as the Eastern Jin's Yi Province, until he was repelled at the Battle of Fei River in 383. Following this defeat, the Former Qin state disintegrated and Fu was assassinated in 385 by Yao Chang, his former subordinate who then founded the Later Qin dynasty. He was considered by traditional histories to be a virtuous and just ruler, who, ironically, by sparing too many of his enemies after defeating them, led to his own downfall.
