唐大中三年宣宗收复三州七关事发微

Research on Tang Xuanzong ’s Territory Recovery of Three-States and Seven-Passes in the Third Year of Dazhong Period

由于宣宗得位不正,为了转移内部矛盾,宣宗利用论恐热以陇右诸州内附的机会,试图经营河陇失地。在遭遇朝臣的反对后,宣宗将具体经营的区域限定在了三州七关,以对应元和年间宪宗意欲通过谈判收回的三州地区。通过收复三州七关,宣宗赢得了足以稳定局势的声望,同时还为其继绍宪宗之政提供了新的素材。与此同时,宣宗君臣通过"河湟"这一媒介,进一步强化了收复三州七关的举动与继承宪宗统治之间的联系。

Owing to the unorthodox inheritance to the throne,Xuanzong tried to transfer the internal contradictions by recovering the lost land in Helong(河陇)taking advantage of Lunkongre’s(论恐热)surrender of land in Longyou(陇右).After encountering the opposition of the courtiers,Xuanzong limited the area to three-states and seven-passes(三州七关),corresponding to the three-states that Xianzong(宪宗)intended to recover through negotiation in the reign of Yuanhe.By recovering the three-states and seven-passes,Xuanzong gained great reputation to stabilize the situation,and also gathered new materials to inherit Xianzong’s policy.Meanwhile,Xuanzong and his courtiers strengthened the connection between the recovery of the three-states and seven-passes and the inheritance of Xianzong policy by the medium of Hehuang(河湟).
