Gwanggaeto the Great (374–413)
Born 374 CE, died 413 CE.
Gwanggaeto the Great (374–412, r. 391–412) was the nineteenth monarch of Goguryeo. His full posthumous name means "Entombed in Gukgangsang, Broad Expander of Domain, Peacemaker, Supreme King", sometimes abbreviated to Hotaewang. His era name is Yeongnak and he is occasionally recorded as Yeongnak Taewang ("Great King" or "Emperor" Yeongnak). Gwanggaeto's imperial reign title meant that Goguryeo was on equal standing as an empire with the imperial dynasties in China. Under Gwanggaeto, Goguryeo began a golden age, becoming a powerful empire and one of the great powers in East Asia. Gwanggaeto made enormous advances and conquests into: Western Manchuria against Khitan tribes; Inner Mongolia and the Maritime Province of Russia against numerous nations and tribes; and the Han River valley in central Korea to control over two-thirds of the Korean peninsula. In regard to the Korean Peninsula, Gwanggaeto defeated Baekje, the then most powerful of the Three Kingdoms of Korea, in 396, capturing the capital city of Wiryeseong in present-day Seoul.
