Nationalism is a way of thinking that says that some groups of humans, such as ethnic groups, should be free to rule themselves. Nationalists think that the best way to make this happen and avoid control or oppression by others is for each group to have their own nation. Some nationalists think this is the best way to save small and weak groups threatened by the mixing of ethnic groups. The other definition of nationalism is the 'identification with one's own nation and support for its interests, especially to the exclusion or detriment of the interests of other nations.'.Nationalism may refer to a state of the mind in respect of socio political phenomenon arising from it's consciousness shared by people (national)of a particular country or territory
