Ethnic nationalism is a form of nationalism where the nation is defined primarily by shared ethnicity, culture, language, or heritage. It emphasizes the importance of a common identity among people who belong to the same ethnic group, often leading to a desire for self-determination or political autonomy. This ideology can manifest in various ways, including the promotion of cultural traditions and the pursuit of political rights for specific ethnic communities. In contrast to civic nationalism, which focuses on shared citizenship and values, ethnic nationalism can sometimes lead to exclusionary practices. It may foster a sense of belonging among members of the ethnic group while marginalizing those who do not share the same background. Historical examples include the rise of nationalist movements in Eastern Europe and the Balkans, where ethnic identity played a significant role in political conflicts.
