Nationalism

1. The belief by a number of people that they constitute a nation, and behaviour in accord with this; for example, defence of sovereignty or revolution to attain self-determination, or self-governing status. Perception of historic nationhood may be based on homogeneity or continuity of geographical tenure, or claims or history of linguistic or ethnic homogeneity. Claimed uniqueness of religion has also been a factor.

2. Nationalist movements of a revolutionary nature, possibly motivated by Marxist ideology.
