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.
Gwanggaeto begins his conquest of Dongbuyeo in 410 with a massive army, against whom the Dongbuyeo army is no match, and it suffers a series of defeats, finally surrendering to Goguryeo after King Gwanggaeto has conquered sixty-four walled cities and more than fourteen hundred villages.
Gwanggaeto also has attacked several Malgal and Ainu tribes further north, bringing them under Goguryeo domination.
