Feelings of resentment toward those who were not native citizens rose during world war i. this was known as nationalism.

This is known as Nativism.

Explanation:

Nativism for anthropology is every action that tries to value the culture of a place, in reaction to the imposition of an external, generally dominant culture. Nativism is especially felt in the history of peoples who have been colonized by others, often through revolts and riots, culminating later in their own emancipation - or in complete acculturation.
