What term describes a policy of prioritizing native-born citizens over immigrants?

The term that describes a policy of prioritizing native-born citizens over immigrants is nativism. Nativism is rooted in the belief that the interests of native inhabitants should take precedence over those of immigrants. This ideology often promotes the idea that native-born citizens are more entitled to social, political, and economic advantages, leading to discrimination against immigrant populations.

Historically, nativism has manifested during various periods in U.S. history, particularly during decades of significant immigration, where native-born citizens viewed newcomers as threats to their job stability, culture, or safety. This sentiment sparked various movements and policies aimed at limiting or controlling immigration and promoting the interests of existing citizens over those who are newly arrived.

The other terms have different focuses, with nationalism emphasizing pride and allegiance to one's nation; isolationism advocating for avoiding international alliances or conflicts; and expansionism relating to the policy of territorial or economic expansion. Each of these concepts operates in distinct contexts that do not specifically emphasize the prioritization of native-born citizens over immigrants, which is the core of nativism.
