武德年间李世民秦王府址的变动

Location Changes of Li Shimin's Palace during the Wude Period of Tang Dynasty

武德年间李世民秦王府的方位因徐松《唐两京城坊考》的误读而模糊不清。借助吕大防《长安图》碑拓残片和《阁本太极宫图》传本等文献,可以确认武德初年至五年七月,李世民居于太极宫内西侧的承乾殿,武德五年七月之后迁至太极宫外西北方向的弘义宫。弘义宫亦为李世民发展势力、预谋政变提供了一些便利。承乾殿、弘义宫相对太子东宫都位于西方,衍生出了“西宫“”西府”等指称秦王府的概念。

The location of Li Shimin's Palace(Qinwang fu,秦王府)during the Wude period of the Tang dynasty was unknown because of the misunderstanding in Tang Liangjing Chengfang Kao(《唐两京城坊考》)written by Xu Song(徐松).After analyzing Lu Dafang's Chang'an map(《长安图》)and Tai Chi Palace Map(《太极宫图》),this paper finds that Li Shimin had lived in the Chengqian Palace in the west side of Tai Chi Palace from the early Wude period.In the July of fifth year of Wude period,Li Shimin moved to live in Hongyi Palace in the northwest side of Tai Chi Palace,which provided convenient for Li Shimin to enhance forc‐es and stage a coup.Chengqian Palace and Hongyi Palace were located in the west side of prince's Palace(Dong gong,东宫),which produced the concept of"West Palace"(Xi fu,西府)referred to Li Shimin's Palace.
