King Dongcheon of Goguryeo (209–248, r. 227–248) was the 11th monarch of Goguryeo, the northernmost of the Three Kingdoms of Korea.
He was the grandson of Goguryeo's eighth ruler, Sindae and the son of the tenth ruler, Sansang. His mother was King Sansang's royal concubine, from the Jutong-chon of Gwanno-bu. He was made crown prince in 213, and rose to the throne upon Sansang's death.
In 238, Dongcheon was able to ally with the Wei, one of the three Chinese kingdoms in northernwest area, in order to destroy the Gongsun family and erase its influence over Liaodong Peninsula and other areas bordering Goguryeo. The war on the Gongsun was a victory, but Goguryeo's ally, Wei, eventually became a new threat.
As Gogeryeo consolidated its power, it proceeded to act to conquer the territories on the Korean peninsula which were under Chinese rule. Goguryeo initiated the Goguryeo–Wei Wars in 242, trying to cut off Chinese access to its territories in Korea by attempting to take a Chinese fort. However, the Chinese Wei state responded by invading and defeated Goguryeo. Hwando was destroyed in revenge by the Chinese Wei forces in 244.
Dongcheon sent an army to attack Wei's Yodong fortress in 242 to expand Goguryeo territory, but Wei retaliated in a most violent fashion two years later. In 244, Wei sent an invasion force of 10,000 to Goguryeo and took and burnt the capital city of Hwando, forcing Dongcheon to flee the capital. Staying in Okjeo, his forces managed to return long-standing capital of which structures were severely destroyed only to move its capital to current Pyeongyang in 246. The exact location of the new capital has been still disputed.
Then, according to the Korean book, the Samguk Sagi, a Goguryeo general named Yu Yu (유유, 紐由) approached the Wei encampment and fooled the Wei commander into thinking that Goguryeo had come to surrender. Yu Yu took this chance to murder the commander and then committed suicide, causing great confusion and discord in the Wei army. King Dongcheon received news of Yu Yu's death and ordered that a memorial be made for Yu Yu the Patriot. Then, he led his armies in the attack to push the Wei forces out of Goguryeo territory. General Mil U (밀우, 密友) and Yu Okgu (유옥구, 劉屋句) also repulsed the Wei forces. The Goguryeo forces won this battle, and regained all of the territory that had been lost from defeats against the Wei. This passage was not paralleled in Chinese records, and Hiroshi Ikeuchi points out its errors: the author of this passage in Samguk Sagi regarded the region of South Okjeo and Lelang as identical, while in fact they are on opposite sides of the peninsula; also, the references to the "Eastern Department" for Yu Yu and Mil U are anachronistic, since Goguryeo did not divide the country into departments until the middle of the Goguryeo dynasty — that is, after Dongcheon's reign. As such, Ikeuchi considered the Samguk Sagi stories of the Wei invasion unreliable.
