Ethnic nationalism is a form of nationalism where a group of people identifies primarily with a specific ethnic group. This ideology emphasizes shared cultural traits, language, and history, often leading to a desire for self-determination or political sovereignty. Ethnic nationalists believe that the nation should be defined by its ethnic composition rather than by citizenship or political boundaries. This concept can lead to the formation of nation-states that prioritize the interests of a particular ethnic group, sometimes resulting in tensions with other groups. Examples of ethnic nationalism can be seen in various regions, such as the Balkans and Kurdistan, where ethnic identities play a significant role in political movements and conflicts.
