Which term describes americans who were opposed to immigrants?

Nativism is the political position of supporting a favored status for certain established inhabitants of a nation (i. e. self-identified citizens) as compared to claims of newcomers or immigrants. According to Fetzer, (2000) opposition to immigration is common in many countries because of issues of national, cultural, and religious identity. The phenomenon has been studied especially in Australia, Canada, New Zealand, and the United States, as well as Europe in recent years, where immigration is seen as lowering the wages of the natives.
