Answer:
The central plank of the Know Nothing Party in the 1856 election was anti-foreign and anti-Catholic.
Explanation:
The Know Nothing Party was a right-wing populist party in the United States from 1844 to 1860 that sought to combat immigration, especially Catholic immigration from Ireland and Germany.
Catholic Irish colonists were considered anti-American and under papal authority. The party was at its most active from 1854 to 1856. However, the party's importance remained low, with no strong leader and supporters divided over ending slavery.
