Overview
Yao Hong (; 388–417), courtesy name Yuanzi, was the last emperor of the Qiang-led Later Qin dynasty of China. He was the oldest son and heir of Yao Xing (Emperor Wenzhao), who was already regarded as kind but weak during his father's reign, and after his father's death, with the state already weakened by attacks by the rebel Xia state and with his brothers and cousins repeatedly rebelling, the Jin general Liu Yu took advantage of Yao Hong's weaknesses to conquer Later Qin. After he surrendered, Liu Yu had him delivered to the Jin capital Jiankang and executed.
Under Yao Xing's reign
Yao Hong was born in 388, during the reign of his grandfather Yao Chang (Emperor Wuzhao), two years after Yao Chang took Chang'an as his capital and created Yao Hong's father Yao Xing as his crown prince. He was Yao Xing's oldest son. The first historical reference to Yao Hong was in 402, when Yao Xing, who became emperor in 394, created him crown prince, after much hesitation, as Yao Hong was described as loving and kind, but weak in his personality and often ill. Yao Hong was also described as favoring arts and literature. Later in 402, when Yao Xing battled Emperor Daowu of Northern Wei, Yao Hong was in charge at the capital. In 407, Yao Xing transferred some imperial authorities to him. In 409, when Yao Xing was battling the rebel general Liu Bobo, who had established Xia, Yao Hong was again in charge of the capital when Liu Jue rebelled, and Yao Hong defeated his rebellion. When his subordinates suggested that the victory be commemorated on an open bulletin, written on cloth, Yao Hong declined, reasoning that it was his responsibility to make sure that no rebellion occurred, and that such a victory over a rebel was nothing to be proud of.
By 411, Yao Hong's brother Yao Bi the Duke of Guangping, who was much favored by Yao Xing for his talents, was conspiring with his associates to seize the crown prince position from Yao Hong. For the next several years, Yao Bi tried to undermine Yao Hong's authority whenever he could, and in 414, Yao Bi falsely accused Yao Hong's associate Yao Wenzong of crimes, causing Yao Xing to force Yao Wenzong to commit suicide. This caused many imperial officials to fear Yao Bi's power, and many joined his conspiracy. As Yao Xing grew ill that year, Yao Bi secretly planned a coup, causing his brothers Yao Yi, Yao Huang, and Yao Chen to mobilize their forces to prepare to act against him.
