Fu Deng
Yao Chang died around the new year 394 and was succeeded by his son Yao Xing. While Yao Xing tried to keep news of Yao Chang's death a secret, the news still got to Fu Deng. Fu Deng, extremely glad to hear about Yao Chang's death, prepared to launch a major assault against Later Qin—he had his brother Fu Guang (苻廣) defend the base of Yongcheng (雍城, in modern Baoji, Shaanxi) and Fu Chong defend the base of Hu Kong Castle, and, in his anxiety, did not make sure that his army had sufficient water supply. Yao Xing set up his army at Mawei (馬嵬, in modern Xianyang, Shaanxi) to prevent Former Qin forces from reaching the river near Mawei, and Former Qin forces collapsed in thirst. Upon hearing the defeat, Fu Guang and Fu Chong abandoned the two bases that they were holding, and Fu Deng was unable to recapture them. He instead fled to Pingliang and then into the mountains. He sent his son Fu Zong the Prince of Ruyin to Qifu Gangui and married his sister the Princess Dongping to Qifu Gangui as his princess, seeking aid from Qifu Gangui. Qifu Gangui sent his general Qifu Yizhou (乞伏益州) to aid Fu Deng, but as Fu Deng came out of the mountains to join Qifu Yizhou's forces, Yao Xing ambushed and captured him, and then executed him. He disbanded Fu Deng's troops and gave Fu Deng's Empress Li to his general Yao Huang (姚晃).
