Nationalism is a complex set of beliefs, political ideas, and social movements that express a strong sense of identification with a given national community and pursue the interests, unity, and sovereignty of that community, often prioritizing national interests above all other considerations. Nationalism typically involves a belief in the unique character and destiny of one's nation, a sense of pride and loyalty to the nation, and a desire to promote its culture, interests, and well-being. It can be a powerful force in shaping political landscapes, driving movements for national independence, unification, or expansion, and influencing international relations. While nationalism can foster social cohesion and a sense of collective identity, it can also lead to exclusionary attitudes towards other nations and minority groups, as well as to conflict and rivalry between nations.
