Nationalism influences political behavior in different countries by shaping citizens' identities and their perceptions of state and culture. In some contexts, nationalism fosters unity and pride in national achievements, while in others, it can lead to exclusionary practices and conflict with minorities or other nations. This influence often affects voting patterns, as nationalistic sentiments can drive support for specific political parties or policies that promote national interests. Furthermore, nationalism can impact foreign relations, prompting policies aimed at protecting national sovereignty or cultural heritage, which can create tensions on the global stage.
