ethnic nationalism

Ethnic nationalism, also known as ethnonationalism, is a form of nationalism in which the nation and nationality are defined in terms of ethnicity, with emphasis on an ethnocentric (and in some cases an ethnostate/ethnocratic) approach to various political issues related to national affirmation of a particular ethnic group.

The central tenet of ethnic nationalists is that "nations are defined by a shared heritage, which usually includes a common language, a common faith, and a common ethnic ancestry". Those of other ethnicities may be classified as second-class citizens. Because of these attributes, ethnic nationalism is closely related to nativism, and is associated with the radical right.
