The secret organization of the nativists became known as the party?

The secret organization of the nativists became known as the Know-Nothing Party in the 1850s. This group emerged in response to the increasing Immigration, particularly from Ireland and Germany, and advocated for anti-immigrant and anti-Catholic policies. Members often responded with "I know nothing" when asked about their activities, which contributed to the party's name and secrecy. The Know-Nothing Party sought to influence politics by promoting nativist sentiments and limiting the rights of immigrants.
