Goguryeo

Goguryeo (Hangul: 고구려; hanja: 高句麗; RR: Goguryeo; MR: Koguryŏ, Korean pronunciation: [koɡuɾjʌ], 37 BCE–668 CE), or Goryeo (Hangul: 고려; hanja: 高麗; RR: Goryeo; MR: Koryŏ, Korean pronunciation: [koɾjʌ]), was one of the ancient Three Kingdoms of Korea, located in the northern and central parts of the Korean Peninsula and the southern and central parts of inner and outer Manchuria. Goguryeo was an active participant in the power struggle for control of the Korean peninsula and was also associated with the foreign affairs of neighboring polities in China and Japan.

The Samguk Sagi, a 12th-century text from Goryeo, indicates that Goguryeo was founded in 37 BCE by Jumong (hanja: 朱蒙 ), a prince from the Buyeo kingdom, who was enthroned as Dongmyeong of Goguryeo. There is archaeological and textual evidence from Chinese geographic monographs that suggests that Goguryeo may have been in existence since the second century BCEm around the fall of Gojoseon, an earlier kingdom which also occupied southern Manchuria and the northern Korean Peninsula.
