In that same year, Hae Buru founded another Buyeo, which he named Dongbuyeo, due to its position east of Bukbuyeo.
According to the Samguk Yusa,[1] Aranbul, a minister of the Buyeo court, had a dream in which the Heavenly Emperor told him that Buyeo was to make way for the descendants of Heaven, and believing that the dream was a sort of omen, he advised his king Buru to move the capital.
Buru later moved his capital to Gaseopwon [ko] (迦葉原), and named his country Dongbuyeo.
Hae Buru eventually got a son, Geumwa, of whom he trained and grew into his successor.
When Hae Buru died in 48 BCE, Geumwa rose to the throne by proclaiming himself "King of Dongbuyeo."
