Question

What contributed to the growth of the Know-Nothing movement in the mid-1850s?

A. The growing native-born population
B. The growing Protestant population
C. The growing immigrant population
D. The growing slave population

Answer 1

The answer is C.) The growing immigrant population.

In the 1850's, the Irish started immigrating to America due to the potato famine. Irish people were mostly catholic at the time, and well, The Know-Nothing Party's ideals were pretty anti-immigrant & anti-catholic. This is what grew the movement, since now they had a large presence to hate.
