The nativist movement of the 1840s which gave rise to the Know-Nothing Party of the 1850s supported?

The nativist movement of the 1840s, which led to the formation of the Know-Nothing Party in the 1850s, primarily supported anti-immigrant and anti-Catholic sentiments. The movement was fueled by a growing fear among native-born Americans that immigrants, particularly Irish Catholics, would undermine American values and institutions. The Know-Nothing Party sought to restrict Immigration and promote the interests of American-born citizens, often advocating for policies that would limit the rights of immigrants and increase the power of native-born Protestants.
