Dongbuyeo
Years: 86BCE - 410
Dongbuyeo (86 BCE - 410 CE) is an ancient Korean kingdom that develops from Bukbuyeo, until conquered by the early Goguryeo, which then grows into one of the Three Kingdoms of Korea.
According to the Samguk Sagi, it is established when Buyeo's king Hae Buru moves the capital eastward by the sea.
