In 926, Parhae was annexed by the
Khitan-led Liao dynasty, incorporated into the Liao vassal
Dongdan Kingdom. The conquered people of Parhae immediately began rebelling against the Liao dynasty. Starting in 927, the Khitans had begun to hunt down and execute all members of the royal family in order to destroy any chance of a new ruler to take the throne. However, several members of the royal family survived. Among them were Crown Prince
Dae Gwang-hyeon. The Crown Prince took Parhae refugees, mostly former
Goguryeo people, and escaped down to their southern neighbor,
Goryeo, where the newly-risen King
Taejo of Goryeo accepted them with generosity. ==See also==
