本书由王朝海编著。正统问题是关于政权合法性的问题，是中国传统文化中一个重要的史学观念，同时也是一重要的政治观念。北魏政权为了同南朝宋、齐等政权争夺华夏正统，历代帝王及士人都付出了巨大努力。北魏王朝从政权合法性的论证、政权合法性的保持、政权合法性的巩固等方面入手，通过"天命王权"、"五德始终"、"国号议定"、"通三统"、"改正朔""华夏文化认同"以及太和期间的迁都、改制等具体措施，向南朝宋、齐等政权展开了全面争夺正统的战争。北魏政权的正统之争在促进中国古代民族融合的进程，影响中国古代疆域的确立，以及中华民族多元一体格局形成的方面都产生了深远的影响。 (The book is edited by Wang Chaohai.Legitimacy is about regime legitimacy, which is not only an important historical concept in Chinese traditional culture, but it is also an important political concept.For contending Chinese orthodoxy from the Song, Qi and other regimes of Southern Dynasty, emperors and literati have paid a tremendous effort.
