What is a key characteristic of nationalism?

Nationalism is fundamentally centered around the notion of a shared identity among a group of people, often tied to common cultural, historical, linguistic, or ethnic traits. This identity fosters a sense of belonging and pride among members of the nation, as they recognize their shared attributes and experiences. The idea of identity based on shared national pride captures this essence, as it emphasizes not just the existence of a national identity, but also the emotional connection that individuals feel toward their nation.

In contrast, while global trade agreements can influence nations, they do not define nationalism itself. Cultural homogenization refers to the process by which cultures become more similar, which might dilute distinct national identities rather than enhance them. Economic isolationism, while it can arise from nationalist policies, is more a strategy of closing off from the global economy than a defining aspect of nationalism. Thus, the strongest and most distinctive characteristic of nationalism is indeed the identity based on shared national pride.
