A Study on Baekje's Political Coups in the Nihon shoki

This article is to study on the records of Baekje's political coup in the Nihon shoki and to examine them through mutual comparison and review with historical records of the Samguksagi . First of all, at the end of the 4th century, we can look at the circumstances of King Jinsa's accession by the usurpation of throne and the situation in which King Asin was enthroned due to the death of King Jinsa by political coup. However, the record of the Nihon shoki, written as if Yamato Wa intervened in the death of King Jinsa and the accession of King Asin, is difficult to be seen as true because it was embellished by the later writers, and rather, it is likely to be a coup caused by the involvement of Baekje people, including Mok clan. In the early 5th century, the Baekje's political coup can be examined through the death of King Guisin and the ascension of King Biyu. According to the record that King Guisin, who had been in office for only eight years, was at a young age when he ascended the throne, King Biyu can be seen not the son of King Guisin, but rather the son of King Jeonji, as shown in the footnotes of the Samguksagi. Moreover, it is possible to assume a political coup caused by King Biyu through the circumstances in which King Guisin suddenly died after eight years of his reign and the situation in which Mokmanchi and Jugun moved to Yamato Wa. As the political coup of Baekje in the 6th century, there are records related to the death of King Dongseong and the accession of King Muryeong to the throne. In the Samguksagi, it is recorded that Baekga killed King Dongseong with a grudge and in the Nihon shoki, it is stated that King Dongseong was killed by political coup because he was cruel and violent toward the people. Moreover, it is highly likely that King Muryeong was involved behind the murder of King Dongseong because of the circumstances in which King Muryeong immediately ascended the throne after the murder of King Dongseong by Baekga. In the early 7th century, Baekje's political coup can be examined through records related to Gyogi in the Nihon shoki. As it is judged that Gyogi was a person who was deported to the island by King Uija and then fled to Yamato Wa, it can be confirmed that there was a palace coup in order to establish the absolute monarchy in the early days of King Uija. As described above, among the records shown in the Nihon shoki, King Jinsa's accession by the usurpation of throne, the coup by King Biyu, and King Uija's palace coup could not be confirmed through Samguksagi. As it is presumed that the Nihon shoki was formed through Baekje's historical records handed down by Baekje immigrants after the destruction of Baekje, a close review of Baekje-related historical records from the Nihon shoki is necessary.
