The main concern of this article is with two basic/fundamental topics in nationalism as an identical claim. First it attempt to reject nationalism as an offspring of modernism and enlightment. By means of distinguishing between classic and modern nationalism, in order to incorporate patriotism the whole history of mankind. On the other hand, it denies nationalism as an ideological claim assorting it as a "theoretical-practical" thought which emerges finally dependent on varies orders of alternative in any distinctive paradigm. This type of organizing, besides other alternatives, has led to world wars, with Mussolini and Hitler as their leaders. Nevertheless Mandela, Sokarno, Mosadegh have exploited it to bring about tidings of liberty and freedom. This article, aims to prove that, despite globalization process, not only Nationalism and Nation State have not lost their Credebility, but they are regarded as valid until today. However, we have attempted to follow the particular view point toward Nationalism and Nation- State in apart of 19th c and 20th c social and philosophical theory.
