馬克思主義對民族問題的理解是一套邏輯嚴密的理論體系,它不是僵化的理論,而是立足於具體的革命階段、用歷史的和發展的眼光來看待民族和民族主義。馬克思和恩格斯對波蘭和南方斯拉夫人的區別對待,充分表明馬克思和恩格斯對具體的民族主義運動的評判標準是它是否有利於社會進步和無產階級革命的實現。

Marxism’s understanding of national question forms a systematic theory. It is not a rigid theory,rather,it is based on specific revolutionary stages and it sees nationalism by a historical and developmental view. Poland and South Slavs were treated differently by Karl Marx and Friedrich Engels,which fully shows that Marxism’s evaluation criterion of concrete national movement is whether it is beneficial to social development and proletarian revolution.
