Having united the Khitan, Abaoji invaded Balhae late in 925, took Buyeo-bu and in the first month of 926 besieged the Upper Capital. Weakened by strife among its nobles, Balhae could not hold out, and Dae In-seon surrendered. The Khitan set up the puppet state of Dongdan in its place.

Balhae refugees tried to revive the kingdom in states such as Jeongan, and in 934 Crown Prince Dae Gwang-hyeon brought tens of thousands of followers to Goryeo, where Wang Geon gave him the royal surname. With Balhae gone, Manchuria passed out of Korean history. In his Balhae-go (1784) the Joseon scholar Yu Deuk-gong called Silla and Balhae the “Northern and Southern States”.
