The Know-Nothing Party was founded in 1849 by nativist Americans.

Explanation:

The Know Nothing movement was a predominantly Nativist American political movement of the 1840s and 1850s. It emerged inspired by the fear of Irish-Catholic immigrants, whose number was growing in the main cities of United States, considering them as hostile to American values, thinking that they were controlled by the Pope. It was a movement of short duration, active mainly between 1854-56. It demanded legal reforms but few were accepted. Among its members were few relevant political figures, and its members were mostly middle class and Protestant. Apparently it was absorbed by the Northern Republican Party.
