遼代 ‘渤海人’ 정치체로서의 兀惹部 연구

Abstract

Examined in this article is how the Balhae faction Yeonpa broke free from Khitan Liao, surrendered to Jeong'an-guk(定安國), and then sought refuge in the Olya-seong(兀惹城) castle, and continued its allied relationship with Olya-bu(兀惹部) to fight Liao. What is explicitly argued here is that Jeong'an-guk and Olya-bu, although both related to the late Balhae, were clearly separate entities. There have been numerous studies focusing on the lives and actions of the Balhae refugees and descendants after Balhae fell, but lack of materials and records always plagued efforts to expand the scope of discussion concerning relevant issues, and the nature of Olya-bu was one of such topics that had never been sufficiently discussed. Recently some scholars came out arguing that Olya-bu and Jeong'an-guk were not two different entities but merely two different names referring to a single entity, but such assessment seems to be in need of reconsideration, as a concrete evidence to support the argument that Olya-bu was simply another name for Jeong'an-guk or vice-versa has never been suggested.
