Nationalism is a political, social, and cultural ideology that emphasizes the interests, identity, and unity of a particular nation or ethnic group. It is characterized by a strong sense of pride in and loyalty to one’s country or people, often accompanied by the belief that the nation should govern itself independently and prioritize its interests over those of other nations.

Nationalism can manifest in the promotion of national sovereignty, culture, language, and history, and it can range from peaceful patriotism to more aggressive or exclusionary forms.

Nationalism has played significant roles in the formation of nation-states, independence movements, and sometimes in conflict when it fuels competition or hostility between nations.
