An alliance of marriage was established between Silla and Goryeong Gaya in 522. For this reason, Goryeong Gaya did not participate in the Baekje-Daegaya offensive against Silla in 538. However, it does not appear that this alliance was of any lasting benefit to the kingdom. According to both the Samguk Sagi and the Japanese chronicle Nihonshoki, Goryeong Gaya fell to Silla in 562. This was the same year that Daegaya was overrun in the south.
The members of today's Hamchang Kim lineage trace their origins to the kings of Goryeong Gaya.
