金官伽倻
Geumgwan Gaya declined due to the wars with Japan and those tribes in north. Its various constituent city statelets fell one by one to Silla. After Geumgwan Gaya capitulated to Silla in 532 AD, its royal house was accepted into the Sillan aristocracy (probably because by that time, a major house of Silla, of the Gyeongju Kim clan, was related to the Gaya royal house, which was Gimhae Kim clan) and given the rank of "true bone," the second-highest level of the Silla bone rank system. General Kim Yu-shin of Silla (also of the Gimhae Kim clan) was a descendant of the last king of Gaya.
