Later Balhae (927 - 935?, 1003?, 1007?, 1114?) was short-lived state established in 927, by the Dae Royal family. It was the first of the immediate successor states to Balhae after its fall to the Khitan in 926. Later Balhae was ruled by the Dae clan, but was eventually taken by Yeol Manhwa in 936 and assimilated into Jeongan, another successor state.
Later Balhae started out as an attempt by the remaining former Balhae Aristocracy to seat a new king onto the Balhae throne and revive the nation. The conquered people of Balhae immediately began rebelling against the Khitan and this matter began to swerve out of control for the Dongdan Kingdom.
Starting in 927, the Khitan had begun to hunt down and execute all members of the royal family in order to destroy any chances of a new king or queen to rise to the throne of Balhae. However, several members of the royal family survived. Among them was Crown Prince Dae Gwang-hyeon. Crown Prince took Balhae 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. Dae clan, however, united the western Amnok River resistance groups and established "Later Balhae" at Holhan Fortress, in 927.
