How can immigration create disagreements about national identity in a nation-state?

Immigration can create significant disagreements regarding national identity within a nation-state by challenging established cultural, religious, and ideological norms. These tensions often arise when immigrant populations maintain strong ties to their countries of origin—a phenomenon known as transnationalism—rather than assimilating into the host society.12

Disagreements typically manifest in the following ways:

• Fragmentation of Identity: When immigrants do not assimilate and instead form concentrated ethnic enclaves, majority groups may perceive this as a threat to the nation’s core ideology and collective identity. This often leads to internal political struggles over how to define national interests and values.1
• Competing Allegiances: Because modern technology and global mobility allow immigrants to maintain continuous contact with their culture of origin, their primary loyalty may remain with their religion or heritage rather than the host state. This creates friction in nations where citizenship is traditionally tied to a specific national or ethnic identity.2
• Nativist Backlash: Nativism often emerges as a political response, where some citizens advocate for exclusionary policies to protect what they view as the "native" cultural or religious character of the state. This discourse can lead to the marginalization of immigrant groups and the promotion of harmful ideologies, such as replacement theory, which frame immigration as a deliberate threat to the nation's survival.3

Ultimately, these tensions force states to grapple with the need to redefine concepts of citizenship and nationality to accommodate increasingly diverse populations while managing the political pressure to preserve traditional national boundaries.2
