Qifu Gangui

Qifu Gangui or Qifu Qiangui, also known by his posthumous name as the Prince Wuyuan of Western Qin (西秦武元王), was a prince of the Xianbei-led Chinese Western Qin dynasty. He was a brother of the founding prince, Qifu Guoren, who became prince after Qifu Guoren's death in 388 because Qifu Guoren's son Qifu Gongfu (乞伏公府) was considered too young for leadership. He subsequently expanded the state's power and influence, but only to an extent, and in 400 after military losses to the Later Qin dynasty, his state was annexed by the Later Qin and he himself became a Later Qin general. However, after the Later Qin was weakened by defeats at the hands of its rebel general Helian Bobo's Hu Xia dynasty, Qifu Gangui redeclared independence in 409, but ruled only three more years before he was killed by Qifu Gongfu in a coup. His son Qifu Chipan defeated Qifu Gongfu and succeeded him as the ruling prince.
