唐玄宗政治合法性建構研究（712-756）

國家權力合法性問題是古代中國連結血緣、文化與社會道德，同時貫穿上層統治階級與下層民心社教的政治思想核心。歷經武周革唐、韋武集團與安樂、太平公主篡權亂政後，甫建之始的玄宗朝即遍含多方政治勢力的博弈，亟待建立正規化、制度化的中央權力體制，為此，李唐統治者結合世俗與宗教的政策手段，構建了服務於政權、君權合法性的意識形態管控體系。唐玄宗通過讖緯、五德運轉說與二王三恪制的傳播與運用，以立論其執政初期的政治合法性又以封禪泰山、儒釋道之教化與“天子之孝”等思想文化政策，對其合法性統治加以鞏固，終實現了“政治倫理化”“倫理政治化”等常態化政治運作、建立並維繫朝代政權的根本目的。

並列摘要

The issue of the legitimacy of state power was the core of political thought in ancient China that linked blood ties, culture, and social morality, and ran through the upper ruling class and the lower public's social and moral education. After the upheaval of the Tang Dynasty during the Wu Zhou regime, the power struggle of the Wei and Wu groups, and the usurpation and misrule by Princess Anle and Princess Taiping, the newly established Xuanzong reign was rife with power games from various political forces and was in urgent need of establishing a regularized and institutionalized central power system. Consequently, the Li Tang rulers constructed an ideological control system serving the legitimacy of the regime and the monarch's power. Emperor Xuanzong, by combining secular and religious thought means, employed divination, the theory of the Five Virtues' Cycle, and the erwangsankezhi, among others, to establish the initial political legitimacy argument. He conducted the Fengshan Sacrifice on Mount Tai and connected the legitimacy and authority of the state with the ethical and cultural psychological domains such as Confucianism, Buddhism, Daoism, and "he filial piety of the emperor" to consolidate his political legitimacy. Eventually, he achieved the normalization of "political ethicization" and "ethical politicization" in political thought operation, and accomplished the fundamental goal of establishing and maintaining the regime of the dynasty.
