Nationalism is a term that refers to a doctrine or
political movement that holds that a
nation—usually defined in terms of
ethnicity or culture—has the right to constitute an independent or autonomous political community based on a shared history and common destiny. Most nationalists believe the borders of the state should be congruent with the borders of the nation. Extreme forms of nationalism, such as those propagated by
fascist movements in the twentieth century, hold that
nationality is the most important aspect of one's identity and attempt to define the nation in terms of
race or
genetics.
