Loyalty to one’s nation and the belief that national interests should take priority shape nationalism as a political force. It can fuel liberation movements against empire and also drive exclusionary or expansionist policies.

Nationalism mobilizes around shared language, culture, history, or ethnicity. Civic versions emphasize shared political values and institutions; ethnic versions stress ancestry and cultural homogeneity. Both have inspired state-building and both have justified discrimination or violence against those defined as outsiders.

In contemporary politics nationalism appears in debates over immigration, trade, sovereignty, and international institutions. Supporters argue it protects self-determination and cultural continuity. Critics warn that it can slide into xenophobia and undermine cooperation on common problems. The intensity of nationalist sentiment fluctuates with economic anxiety, demographic change, and elite cues.
