高句麗와 투르크계 北方勢力의 관계 - 이해의 방향과 연구방법에 대한 모색 -

Abstract

One of the noteworthy issues in the international relations in the 6th-7th century is that Koguryeo sought for solidarity with the Turkic northern power to confront the threats from the Sui and Tang Dynasties. However, the existing researches on the issue only emphasized the fact that the diplomacy of Koguryeo was developed to the grassland in the northern region so that there were lacking efforts to review the stance of the Turkic northern power, the other negotiation paryt. In this regard, there were also lacking researches on the responses taken by the Sui and Tang Dynasties, which might be linked to the situation. Due to the emphasis on the diplomacy of Koguryeo, the trend in the changing international politics was often ignored. The encounter between Emperor Yang of Sui and the ambassador of Koguryeo at Yami Qaghan(啓民可汗)’s army tent in Turkic Khaganate in 607 showed that the connection between Koguryeo and Turkic Khaganate became definitely tangible. However, what is the most important among other meanings in this incident is regarded that the background of the incident originated from the efforts of Yami Qaghan to get out of the influence of Sui and that Emperor Yang made Turkic Khaganate surrender by having a large-scale visit to Turkic Khaganate out of concerns about such move. While the foreign strategy of Koguryeo to have solidarity with Turkic Khaganate was failed due to the unexpected visit by Emperor Yang, the diplomacy of Koguryeo extended to the far Yulin(楡林), was timely due to the move of Turkic Khaganate. It is understood as an extension of such move that Turkic Khaganate stayed out of a war waged by Sui to invade Koguryeon i 612. The trend to put too many meanings on the diplomacy of Koguryeo for the Turkic northern power is found in the research on the confrontation between Koguryeo and the Tang Dynasty. It was understood that the Tang army withdrew from the war in 645 because of the invasion of Seyanto(薛延陀), which was regarded as an achievement of the diplomacy of Koguryeo. However, it is deemed a misunderstanding by overlooking the fact that Tang left the commanders and soldiers of Turkic Khaganate to prevent Seyanto and underestimating the outcome of the Battle in Ansi fortress(安市城 戰鬪). Meanwhile, the fact that the entire Tiele (鐵勒, a confederation of nine Turkic peoples) community including Seyanto confronted the Tang Dynasty indicates that it is required to focus on the changes in the power relation in the northern world and the trend in the leading influence, and to review then foreign strategy of Tang and the development process of the Koguryeo-Tang war. From the perspective, it is thought to be necessary to pay attention to the epitaph in theS ui and Tang Dynasties poured out in China and the resources left by the Turkic northren powers.
