고구려 영류왕 후기 대외정책의 변화와 연개소문의 정변

Abstract

In the end of King Yeongryu’s reign(629~642), the primary concerns of Goguryeo’s foreign policy were Tang and Silla. A turning point was Goguryeo’s defeats by Silla in the Battle of Nangbi fortress in 629 and in the Battle of Chiljung fortress in 638. These incidents caused foreign policy change of Goguryeo’s king who sought a new relationship with the Tang Dynasty. In addition, the relationship between Goguryeo and Tang was mainly influenced by changes in international situations of East Asia and by internal political affairs in China.<BR> At the request of Chinese emperor, King Yeongryu of Goguryeo sent his crown prince to the imperial court in 640. He also asked to allow sons of ruling aristocrats to enter the Imperial Academy(Guoxue ). Instead, the king sought to ensure the safety of Goguryeo. His new foreign policy caused political conflicts: Yeongaesomoon and his followers perceived the king’s foreign policy as a threat which denied the restoration of their country’s power and authority. Moreover, it was considered as treating Goguryeo and Silla as equal vassal states. Therefore, one of the reasons of Yeongaesomoon’s coup was his opposition to the king’s foreign policy.
