“維城作固”與“防閑禁錮”:宗王出鎮與唐代政局

Defending the State or Being Imprisoned:Princes in Local Governance and the Political Situation of Tang Dynasty

唐前期的宗王出鎮受到政治局勢的深刻影響。貞觀初年,唐廷對地方的掌控並不穩固。原隋末羣雄割據的地區,叛亂仍時有發生。唐太宗令宗王出鎮地方,加强中央對地方的控制。這與其他措施一起,確立李唐皇室在國家權力體系中的地位。貞觀後期,宗王在最高權力交接中扮演了重要角色。玄宗時期宗王出鎮政策的變化,是神龍至開元初年政治秩序重建的結果。唐玄宗君臣推崇“公”的政治理念,宗王被排斥在權力結構之外。這一變化也意味着中古皇權統治模式的變革。

In the early Tang Dynasty,princes served as local governors,a role deeply influenced by the political situation of the time.During the early years of the Zhenguan(貞觀)era,the Tang court's control over many regions was unstable.Rebellions frequently erupted in areas previously divided among warlords at the end of the Sui Dynasty.Emperor Tang Taizong responded by appointing princes as local governors to strengthen central control over these regions.This strategy,along with other measures,solidified the Royal Household's position within the national power system.In the later period of the Zhenguan era,princes played an important role in the transition of supreme power.The policy changes regarding princes during Emperor Xuanzong's reign were a result of the political reordering from the Shenlong(神龍)period to the early Kaiyuan(開元)period.Emperor Tang Xuanzong and his courtiers promoted the political concept of‘public interest',leading to the exclusion of princes from the power structure.This shift also signifies a transformation in the mode of medieval imperial governance.
