唐代渤海国王族族属抉微

A Study on the Nationality Origin of the Bohai Royal Family in the Tang Dynasty

渤海国(698-926)是唐代东北重要的民族政权,作为唐朝边疆的羁縻州"忽汗州",同时也是其重要的藩属国,在东北亚发展进程中发挥了重要的历史作用,有着"海东盛国"的美誉[1].围绕渤海国王族的族属问题衍生出对渤海国研究的诸多分歧,这些分歧的核心所在便是渤海建国者大祚荣家族族属未能明确.2013年,苗威先生提出渤海国建国者大祚荣族属契丹的新说之后[2],由此引发了学界的巨大争议,使得许多问题有必要重新加以审视和辨析.本文本着考镜源流、辨章学术的精神,为述清渤海王族之渊源,就大祚荣之族属问题欲继续予以探讨,以就教于诸位方家.

Bohai State(698-926)was an important Jimi(羁縻)and vassal state in northeast of the Tang Dynasty.Under the background of many controversy about the issue of the Bohai royal family,based on Mr.Miao Wei’s theory that Da Zuorong’s family originated from the"Khitan",this paper continued the research and led to three conclusions.Firstly,the surname"da shi"("大氏")of royal family was actually a simplification of the name of the Khitan nobility"Dahe shi"("大贺氏").Secondly,the essence of the"natives"("土人")in the Japanese historical materials Lei Ju Guo Shi(A National History of Gathering Groups,《类聚国史》)was neither Mohe people nor Goguryeo people,it was the Yingzhou people who formed the state with the Khitan as the main group.Thirdly,according to the Xing Tang Shu(《新唐书》),the folk custom of the Bohai is basically the same as the Khitan,because the Bohai royal family was originally Khitan instead of Bohai bordered to the Khitan in west.
