“肇构神京”与“缔我宋宇”:刘宋的王畿设置与疆域界定

Define Territory and Construct Capital:The Legitimate Appeal and Its Operation of Emperor XiaoWu's Succession of the Throne in LiuSong Dynasty

大明三年为刘宋孝武帝朝政治的转折点。此前,孝武帝将统治合法性建立在"孝建缔孝业"上,即以平定太子刘劭之乱、为宋文帝"涤社稷之仇"为其入继大统之由。刘义宣之乱及竟陵王刘诞的潜在威胁,使孝武帝对其资望信心不足,这成为孝武帝增加典签权势以控制方镇宗王和州刺史、以寒人恩倖操纵大政等诸多政治举措的心理因素。大明三年诛杀竟陵王前后,孝武帝转而以受命于天来论证其统治合法性,故而重星变、设王畿、移郊坛、造五路、立明堂。孝武帝的合法性诉求使其更在意北魏对其统治的认可。大明四年至七年,宋、魏交聘常规化,孝武帝通过与北魏互相承认来维系既有疆土。孝武帝崩殂后,其改制即被废除,其原因之一便是在分扬州、设王畿等改制中,造成东诸郡"物情不说,容亏化本"。
