百濟熊津時代의 北方領域

Northern territories of Ungjin Baekje period

Until recently, students of history have believed that the Ungjin(熊津) period of the Baekje(百濟) dynasty was a time of weakness and retreat. History tells us that the Baekje dynasty was seriously damaged by the Koguryo(高句麗) dynasty's southward movement and famous invasion of 475 AD. People have believed that the Baekje dynasty lost its claim to the Han(漢) River area and was forced to move its capital to Ungjin as a result of the Koguryo dynasty's invasion. However, this interpretation of history has recently been shown to be incorrect. By studying " Samguk-saki(三國史記)" carefully, scholars have determined the true story. Baekje did not in fact lose control of the HanRiver valley. Contrary to the idea that Koguryo easily overpowered Baekje, it is now known that Baekje defended itself quite well against Koguryo. In fact, during the battles in the southern part of modern-day Choongcheong (忠淸) and gangwon(江原) provinces, Koguryo was hard-pressed to defend itself against Baekje, Records from Hansan(漢山) Castle, Han (漢) Castle and other places in and around the Han River[such as Soogok(水谷) Castle, Masu(馬首) Castle, Woodoo(牛頭) Castle, Sahyun(沙峴) Castle, Gomok(高木) Castle, Jangryung(長嶺) Castle, Han Castle and Heungak(橫岳)] show that Baekje continued to occupy the Han River valley during this period. Baekje not only retained control of it territories, it also expanded its territory into Shingae(新溪) of Hwanghae(黃海) provinces, including places such as Yeoncheon(漣川), Kimhwa(金化), Chooncheon(春川) and Wonju(原州). Kings Dongsung(東城; 479～501) and Mooryoung(武寧; 501～523) also continued to expand Baekje's power in the period fellowing Koguryo's attack.
