Nationalism has been called as the religion of 19th and 20th century. As a way of thinking about the world, Nationalism emphasizes the importance of nations in explaining historical developments and analyzing contemporary politics and also claims that ‘national character’ id s pervasive factor differentiating human beings.
We must keep certain things in mind before studying the concept of Nationalism before studying it such as ;
1.Nationalism is a sentiment that has to do with attachment to a homeland, a common language, ideals, values and traditions, identifying a particular group which symbols such as flag, songs which defines it as ‘different from other countries. This type of attachment creates an identity and the appeal to that identity has a past and the power to mobilize the people.
2.How a sentiment of attachment to a homeland and common culture can be transferred into a political demand to create a proper state; how is it possible to make this transition ?A theory of Nationalism has to deal questions such as :how does Nationalism use and legitimize the use of violence in its quest for the creation of state ?
3.The most important feature of Nationalism is its capacity to bring together people from different social and cultural levels. Nationalism is not merely an invention of ruling classes to maintain the unconditional loyalty of the masses but also making them believe that they have much in common that is more important than we separates them. This is the one of the basic factors in trying to understand the persistence of Nationalism.
