Which of the following was the main concern of the Know-Nothing Party?

A. Immigrants taking the jobs of American citizens B. Native Americans attacking settlers C. Tariffs being imposed on foreign goods D. Slavery spreading to western territories

The correct answer is A.

The know nothing party of the late 19th century was a political faction that consisted of nativists. Nativists are individuals who think that the wants and needs of native citizens should take priority over those of immigrants. This anti-immigrant stance is rooted in fear that immigrants would take jobs or try to change American culture. This group used violence to scare immigrants. When confronted about their actions, they would say they "know nothing."
