탐라국의 대외교섭과 항로

Abstract

The purpose of this paper is to review the sea routes used by Tamla during negotiations with neighboring countries in the context of Tamla. In the days of Tamla, there were “The Northern Coastal Route”(北部沿岸航路), “The Middle Transversal Route”(中部橫斷航路), and “The Southern Slant Route”(南部斜斷航路) in Yellow Sea(黃海). The northern coastal route was the route used from the Neolithic period, the middle transversal route was developed in the 5th to the 7th century, and the southern slant route was newly developed in the first half of the 9th century. In the late 5th century, Tamla first interacted with Baekje for about 200 years. Immediately after the fall of Baekje in 660, Tamla sought to establish a new diplomatic line with neighboring countries such as Tang, Silla, Japan and the government of Baekje Restoration Movement. In the end, Tamla decided to establish a subordination relationship with Silla in 679, and maintained this relationship until the fall of Silla. The relationship between Tamla and Goryeo continued until 1105 when Goryeo unified Tamla into its own county. In order to negotiate with the countries located on the Korean Peninsula including the Baekje, Silla, and Goryeo, Tamla used a route ‘North part of Jeju Island-Chuja Island(楸子島)-Southwest of the Korean Peninsula’. In the middle of the 7th century, when one ensvoy was dispatched to Tang, he crossed the southwestern part of the Korean peninsula using the ‘North part of Jeju Island-Chuja Island-Southwest of the Korean Peninsula’, then went northward along the western coast of the Korean peninsula, and crossed the middle transversal route. In negotiations with Japan, it crossed the southern coast of the Korean peninsula through the ‘North part of Jeju Island-Chuja Island-Southwest of the Korean Peninsula’, and then used the coastal route through the Tsushima(對馬島) and Iki Islands(壱岐島) to the northern part of Kyushu.
