Early Baekje’s succession to the throneand political change

The early royal family of Baekje was a dual structure of Buyeo clan Onjo-Chogo and Woo clan Biryu-Goi. They caused a political upheaval with the powerful forces around them over the succession to the throne, and as a result, they even carried out a change of royal family. King Chogo consolidated the Woo clan of the Daebang-Michuhol region and took the position of head of the federation for the first time. Afterwards, King Goi deposed King Saban, the grandson of King Chogo, and established the Biryu royal lineage. In this process, King Goi used the military power of the Jin clan, and tried to overcome the problems in the succession process and strengthen the royal authority. However, after King Goi, the failure of China's foreign policy with the county government began to shake the royal power of the Goi dynasty. King Biryu took advantage of this opportunity to lead a political upheaval with the Hae clan and restore the super-ancient kingship. However, as a result of not being able to completely control the Goi power, he had no choice but to hand over the throne to the King of Goi. Afterwards, King Geunchogo completely expelled the Goi forces through political change and established the power of the Chogo kingship. Such a series of historical facts were recorded in the Onjo-Chogo in order to secure the legitimacy of the succession to the throne in the process of compiling the 『Seogi』 during the reign of King Geunchogo. In this process, the throne was arranged in the form of succession in the Biryu-Goi lineage and blood ties, especially the father-son relationship. As a result, the founders of the two lineages, Onjo and Biryu, became brotherly brothers, and the founding tradition was created, which became the source material for the early records of the Baekjebongi.
