苻生
Fu Sheng's reign was one filled with violence, caprice, and cruelty. As he killed official after official in his administration, all of the nobles and officials became fearful of being the next target. A number of officials tried to persuade Fu Jian to overthrow Fu Sheng, and it was in the planning stages that Fu Jian, under the introduction of the official Lü Polou (), met Wang Meng, with whom he immediately developed a friendship. Fu Jian planned to act against Fu Sheng but hesitated, since Fu Sheng was a powerful warrior. However, after news leaked that Fu Sheng had planned to kill Fu Jian and his brother Fu Fa, Fu Jian and Fu Fa took immediate action and attacked the palace while Fu Sheng was in a drunken stupor. Fu Sheng's guards surrendered without a fight, and Fu Jian put Fu Sheng to death and took over the throne. He did not, however, take imperial title as Fu Sheng had, but claimed the title "Heavenly King" ("Tian Wang"). He posthumously honored his father Fu Xiong as an emperor, and he honored his mother Lady Gou as an empress dowager. His wife Lady Gou was created empress.
