Interracial marriage in Korea dates back to at least the Three Kingdoms period. Records about the period, in particular the section in the "Samguk Yusa" about the Gaya kingdom (it was absorbed by the kingdom of Silla later), indicate that in 48 AD, King Kim Suro of Gaya (the progenitor of the Gimhae Kim clan) took a princess (Heo Hwang-ok) from the "Ayuta nation" as his bride and queen. "Ayuta" is the Korean name for the city of Ayodhya in India. Two major Korean clans today claim descent from this union.
