Fu Pi
Later in 386, Fu Pi died in battle against Jin, and the territory under his direct control (modern Shanxi), as well as his officials, fell into the hands of the Western Yan emperor Murong Yong. His official Kou Qian (寇遣) escorted his sons Fu Yi (苻懿) the Prince of Bohai and Fu Chang (苻昶, note different character than Fu Deng's father) the Prince of Jibei to Fu Deng's domain. Fu Deng, after mourning for Fu Pi, proposed to have Fu Yi declared emperor, but his subordinates all opined that given the state Former Qin was in (down to holding not much more than the territory under Fu Deng's control), the state needed an older emperor; at their suggestion, Fu Deng himself took the throne. He made Fu Yi his crown prince.
