Taejo of Goryeo
Though Balhae fell, it left a further legacy. After most population of Balhae was moved to Khitan by Liao Dynasty, the last princes of Balhae quickly gathered the Balhae Aristocracy and retreated to Goryeo for sanctuary. Taejo of Goryeo gladly took them in and the Dae family continued on and still survives to this day as the Hyeop-gye Tae clan (협계 태씨).
