6세기 동아시아 정세와 무령왕의 대고구려전략 = The Situation in East Asia during the 6th Century and King Muryeong's Strategy for Goguryeo

다국어 초록 (Multilingual Abstract)

In this article, I tried to understand the diplomacy with Liang(梁) that Baekje developed during the King Muryeong’s reign in connection with the situation of the Chinese continent at that time, and examine the influence of Baekje on expanding its influence on the Yeongsan River and Seomjin River basins and the situation on the Korean Peninsula by linking foreign relations for Goguryeo and diplomacy with Silla.
The situation of the Chinese continent changed to the inferiority of Southern Dynasty from the second half of the 5th century, and in the first half of the 6th century, the internal conflict of Beiwei(北魏) created a favorable situation for Liang. Baekje developed diplomacy in response to the situation of the Chinese continent, which was the growth of the Southern Dynasty and the decline of the Northern Dynasty, but failed to send envoys frequently due to internal situations and transportation routes. During the King Muryeong’s reign, Baekje strengthened its control over the Yeongsan River and Seomjin River basins, which led to the foreign strategy to completely territorialize the Yeongsan River and Seomjin River basins and expand its influence in the Gaya region during the King Seong’s reign.
The Baekje’s strategy for Goguryeo during the King Muryeong's reign was an offensive shift, and its strategic goal, the Han River basin, was continuously targeted, resulting in tangible results during King Seong's reign. The strategy of offensive shift for Goguryeo was a preemptive attempt to extend the royal authority and secure the legitimacy. Baekje had a discriminatory perception while maintaining friendly relations with Silla. Since the discriminatory perception that contradicts the reality of Silla's rapid growth did not disappear even during the King Seong’s reign, in result Silla plunder the Han River basin due to cracks in friendly relations.
