魏晋南北朝的天下三分之局试析

A Tentative Analysis of the Triangular Balance of Powers During the Wei,Jin and the Northern and Southern Dynasties

天下三分的政治设计并不始于三国时代,魏晋南北朝的天下三分之局也不止于三国时代,还应包括东晋十六国的东晋、前秦、前燕之鼎立,南北朝后期的梁陈、东魏北齐、西魏北周之鼎立。北宋以前的分裂形式,体现出从东西二元到三方鼎峙到南北分立的变化趋势。

The political design of a triangular balance of powers did not start from the period of the Three Kingdoms,neither was it the only case during the Wei,Jin and the Northern and Southern Dynasties.It should include also a balance among the Eastern Jin,the Former Qin and the Former Yan,as well as that among the post Three Kingdoms of the late Northern and Southern Dynasties.The state division before the Northern Song Dynasty displayed a tendency from one between the east and the west,one among three powers,to one between the north and the south.
