Nationalism is an ideology that says that every ethnic group of humans should be free to rule itself. Nationalists think that the best way to make this happen is for every ethnic group to have its own nation or society that they can rule without being controlled or oppressed by anybody else. Many nationalists think that nationalism is the best way to save small and not powerful groups, which are threatened by the mixing of ethnic groups. Nationalists think that the world is better with lots of cultural diversity. They also think that diversity is threatened by worldwide influences and mixing.
Nationalism is the love of one's country and the desire to be free from other countries.
