Balhae at its greatest
territorial extent
Balhae (698 – 926) was a
Korean kingdom established after the fall of Goguryeo that existed
during the North South states period of Korea along with Unified
Silla. After Goguryeo's capital and southern territories fell to
Unified Silla, Dae Jo-yeong, a former Goguryeo general, whose
father was Dae Jung-sang, established Jin, later called Balhae. It
was a successor state to Goguryeo.
Balhae occupied southern parts of Manchuria (Northeast China) and
Primorsky Krai, and the northern part of the Korean peninsula. It
was defeated by the Khitans in 926, and most of its northern
territories were absorbed into the Liao Dynasty while the southern
parts were absorbed into Goryeo.
