一《蒙古秘史》及其他中华民族的历史发展一再证明:多民族历史的演进,反映在史学上是史学之民族内容的不断丰富。元朝统治者固然重视本民族的历史以及元皇朝政治统治的历史,同时也重视辽、金、宋三朝的历史,显示出了政治上的博大胸怀和对多民族历史的新认识。元朝统治者的现实民族政策同他们对于多民族国家历史的认识存在着并不完全一致的地方, The History of the Mongolian Mysteries and other historical developments in the Chinese nation have repeatedly proved that the evolution of the multi-ethnic history is reflected in the historical enrichment of the historiography of the nation’s content. Although the Yuan Dynasty rulers attached great importance to the history of their own nation and the history of the Yuan dynasty’s political rule, they also attached importance to the history of the Liao, Jin and Song dynasties and displayed a broad political ambition and a new understanding of the history of many ethnic groups. The actual ethnic policies of the rulers of the Yuan Dynasty did not exactly agree with their understanding of the history of the multi-ethnic country.
