The so-called Know-Nothing Party produced virulent anti-immigrant rhetoric. Its supporters believed German and Irish immigrants were disrupting American democracy, as depicted in this ca. 1850s political cartoon, likely penned by political cartoonist John H. Goater. Original held at the New York Public Library. The author thanks Tyler Anbinder for providing the location of the original cartoon, and Jason Stacy for help in tracing the cartoon’s origins, particularly in identifying its hitherto unknown artist.
