唐の建国と匈奴の費也頭

抄録

Raising an army and founding T'ang Dynasty by Li Yuan (李淵) have been understood from the viewpoint of the group of Kuan-lung (関隴) rulers since Hsi-wei (西魏) period, through the analysis of the leading members of Li Yuan group by now. However, I should like to pay attention to the Pi-yeh-t'ou of Hsiung-nu in Ordus for the following reasons. (1)Preceeding the raise of his army, Li Yuan appointed his three sons as feudal lords of the far wesl lands, they are Lung-hsi (隴西), Tun-huang (敦煌), and Ku-tsang (姑臧). Soon after he entered Ch'ang-an (長安), he drew back these appointments, So these seemed to have been his strategic preparations to aim Ch'ang-an from Tai-yuan (太原). The clue to understand this relationship between Li Yuan and these three lands, is found in the genealogy of Tou (竇), Li Yuan's empress reported in "Genealogical Tree of Prime Ministers (宰相世系表)" in "Hsin T'anbg-shu (新唐書)". (2)Tou's original family name was He-tou-ling (〓豆陵), in "Genealogical Tree". This Tou was connected with famous Tou family in Han (漢) period, accordig to the legend of the founder of the T'o-pa tribe (拓抜部) known in the preface to "Wei-shu (魏書)". At this occasion, they invented the story that the father of Tou family of Han period came from the land of Lung-hsi, Tun-huang and Ku-tsang. As a result, we can assume the intervention by He-tou-ling family behind Li Yuan's feudal appointments of his three sons in these lands. (3)He-tou-ling family originated from the Pi-yeh-t'ou tribe of Hsiungnu and belonged to He-lien Hsia Dynasty (赫連夏国) originally. They lived nomadic life in the province of Pei-he (北河) even after the downfall of Hsia (夏) Dynasty and possessed enough power to revolt against Pei-wei (北魏) in the reign of Emperor Hsiao-wen (孝文). As the influence of Pei-wei decreased after the disturbance of Liu-chen (六鎮之乱), they spread widely over Ordus and He-hsi-t'ung-lang (河西通廊). Because of their great power, Kao Huan (高歓) and Yu-wen T'ai (宇文泰) even quarrelled over Pi-yeh-t'ou in the province of Ordus. (4)In the meantime, it is evident from many examples that the strategic point of North China in order to take possession of Ch'ang-an lies in Tai-yuan and Ling-chou (霊州). Therefore, Li Yuan obtained Ling-chou under control through the alliance with the Pi-yeh-t'ou, and He-hsi (河西) route by feudal appointments of his three sons in Lung-hsi, Tun-huang and Ku-tsang. He also controled Turk (突厥), the menacing power in the north, and Hsueh Chu (薛拳), the most powerful warlord in the west, and managed to build up a scheme to enter Ch'ang-an. During T'an period, Tou family's fame had no equal, because they had not only a genealogical relation to Kao-Tsu (高祖), but also they played important parts to found the dynasty. In the result of this discusson, it can be said that Hsiung-nu did not disappear simply after the downfall of He-lien Hsia Dynasty (赫連氏夏国) in the history, but they actually parti cipated in founding T'an Dynasty.
