Nationalism and Populism
Two powerful political ideas that shape identity, representation, sovereignty, and foreign policy
Nationalism emphasizes the identity, interests, and sovereignty of the nation, while populism frames politics as a struggle between ordinary people and a corrupt or detached elite.

Definition
Nationalism is a political idea that places the nation, its identity, its sovereignty, and its perceived interests at the center of political life. It can emphasize shared history, language, culture, citizenship, territory, institutions, or national self-determination.
Populism is a political style or ideology that frames society as divided between ordinary people and a corrupt, distant, or self-serving elite. Populist movements often claim to represent the true will of the people against established parties, courts, media, experts, bureaucracies, or international institutions.
The two concepts often overlap, but they are not the same. Nationalism can be civic, ethnic, defensive, anti-colonial, liberal, conservative, or expansionist. Populism can appear on the left or right, and may attach itself to nationalism, socialism, anti-corruption politics, religious identity, or anti-globalization movements.
Why It Matters
Nationalism and populism matter because they influence how governments define sovereignty, citizenship, borders, trade, migration, alliances, and national interest. They can strengthen democratic participation and collective identity, but they can also intensify exclusion, polarization, and distrust of institutions.
In foreign policy, nationalist and populist politics can challenge multilateral institutions, reshape alliance commitments, increase skepticism toward globalization, and prioritize domestic political mandates over international cooperation. Brexit is a major example of how sovereignty-focused and anti-elite narratives can reshape state strategy.
For political analysis, the key is to separate the two concepts carefully. A nationalist movement is not automatically populist, and a populist movement is not always nationalist. Their effects depend on institutions, leadership, minority protections, media systems, economic conditions, and historical context.
Nationalism and populism are key GPS concepts for analyzing domestic political forces that reshape foreign policy, alliances, trade, migration, regional integration, democratic institutions, and public trust. GPS should track how leaders invoke national sovereignty, anti-elite narratives, border control, cultural identity, economic grievance, and democratic legitimacy to justify policy change.
