조선후기의 新羅正統論과 渤海史의 인식

Abstract

There have been two different ideas to understand the time when Silla and Balhae coexisted. One way has comprehended it as ‘the period of North and South kingdom’, but the other has deemed it ‘the period of unified Silla and Balhae’. The term of ‘unified Silla’ means that Balhae is excluded from Korean history. However, the idea of ‘unified Silla’ is being still supported to emphasize the opportunity to form Korean people. The concept of ‘unified Silla’ has common ground with the theory of Silla’s legitimacy prevailing in Jpseon period and ‘unification of Korean Peninsula’ in modern Manseonsahak(historical studies on Mancuria and Joseon) in the way that it discriminates itself from Silla kingdom during the Three-Kingdoms era. Also, it is the same that Balhae has been ruled out from the view of ‘unified Silla’ which gave the meaning to Silla’s final victory as historical milestone. Therefore, this study exmaines the development in the theory of Silla’s legitimacy and recognition of Balhae’s history to understand the current problem of dual attitude toward Balhae’s history and search for alternative. Most representative history books in Joseon period from Dongguktonggam to Dongsagangmok, which were written in the historical view with the theory of legitimacy, treated Balhae’s hisotry as a maginal country. Goguryeo was rediscovered in the external crisis after the two struggles against Japanese and Manchus. Balhae succeeded to Goguryeo began to receive attention with it. Donsa written by Yi Jong-huee completely denied the theory of Silla’s legitimacy by means of the theory of Dangun and Gija’s legitimacy. Balhaego written by Yu Deuk-gong could raise the idea of North and South kingdom era where Silla and Bahae coexisted on the Donsa’s view. With Dongsa, Dongsaganmok, the history book wrtten in theory of legitimacy, was much helpful for Yu to write Balhaego.
