How can nationalism become ultranationalism?

Nationalism can become ultranationalism when the focus shifts from a sense of pride in one’s nation to an exclusionary and often aggressive ideology that prioritizes the interests of one nation above all others. This transformation is often fueled by perceptions of external threats, economic instability, or social division, leading to an intense belief in national superiority. Ultranaționalism can manifest in xenophobia, militarism, and the suppression of dissenting voices within the nation. Ultimately, it fosters an environment where unity is achieved through division and hostility towards perceived outsiders.
