Geumgwan Gaya

42 CE – 532 CE (approx.) · capital Gimhae

The leading early state of the Gaya confederacy at modern Gimhae, a port kingdom whose iron trade linked Korea, Chinese commanderies and Japan.

Origins

Geumgwan Gaya grew out of Guya-guk, a Byeonhan statelet at the mouth of the Nakdong river. Its founding legend tells of King Suro hatching from a golden egg in 42 CE and marrying Heo Hwang-ok, a princess said to have sailed from a distant land called Ayuta.

Rule and society

Kings at Gimhae controlled iron production and a harbour where traders from Lelang, Daifang and Wa called. The royal cemetery at Daeseong-dong contains iron armour, horse gear and weapons, plus Japanese-style objects. Until about 400 it led the Gaya states, but a Goguryeo campaign that year to aid Silla broke its strength.

Decline and legacy

Weakened and squeezed by Silla, King Guhyeong surrendered to King Beopheung of Silla in 532 and was given rank and land. His great-grandson Kim Yu-sin became the general who helped Silla unify Korea.
