Review on the Relationship Between Mahan and Baekje: The Same Entities with Different Names

Currently, in Northeast Asia, where Korea, China, and Japan are located, there is still a fierce debate over the extent of the territories in ancient history. This research aimed to prove that Mahan and Baekje, ancient Korean states, were essentially the same entitty only with different names employing new methodologies including comparative analysis of ancient Historical records from Korea, China and Japan, analysis of clans and place names, as well as examination of various inscriptions, stele texts, and genealogical data. The research results revealed that Baekje, referred to as Dongyi tribes in China and as Gudara in Japan was confirmed to be another name of Mahan. Baekje was established as a tributary of Mahan in the ancient land of Daebang and Mahan and Baekje coexisted peacefully for over 460 years, and they even engaged in a division of roles in diplomatic activities. In Tang Dynasty, when Baekje was conquered, King Kim Chun-chu of Silla was appointed as the general secretary of the Yuyi Clan Conquest. The titles of Yuyi and Mahan also appear in the positions of Su Dingfang, which refers to the Mahan forces that existed around the Yeongsan River basin as Yue Zhi. All these facts confirm that Mahan and Baekje were indeed the same entities, merely known by different names in historical Records. The aforementioned research results demonstrate that Mahan-Baekje was a very Powerful political entity spanning the Korean Peninsula, the northeastern region of China, and the Japanese Archipelago. This serves as strong evidence against the claims of China’s Northeast Project and Japan’s theory of the Imna Japan Province, highlighting the historical inaccuracies in these assertions.
