Biography
Dae Gwang-hyeon was probably the first son of King Dae Inseon, and the last crown prince of Balhae.

After several months of oppressing Balhae, the Khitan-led Liao dynasty army swept through Balhae and reached Shangjing Longquanfu (Sanggyeong), the capital city. The last king of Balhae surrendered to the Liao forces and the capital was captured. The king was captured, but the Crown Prince managed to gather an army and escape to Goryeo in hopes of gathering strength to avenge the humiliating defeat and downfall of his dynasty. Dae Gwang-hyeon arrived with his fellow Balhae people during the 1st month of 937, the 17th year of King Taejo's reign. He was warmly welcomed and included into the ruling family of Goryeo by Wang Geon, bringing a unification of the two successor states to Goguryeo.

He had at least one son, Dae Do-su, who later led Goryeo to victory against the Liao dynasty at the Battle of Anyung Fortress. He was also the ancestor of the Hyeopgye and Yeongsun Tae clan and the Miryang Dae clan, most of whose members currently reside in South Korea.
