The sudden implosion of the Know Nothings should also serve as a warning to Republicans that the forces that have propelled them to the apex of American politics, helping Donald Trump win the White House, can also tear them apart, leaving barely a trace. The Know Nothings today are a barely remembered footnote to American history; if it continues on its current path, today’s version could end much the same.

Much like QAnon, the Know Nothings started life as a secretive cabal convinced that the country was being controlled by an even more secretive cabal — and much like Trump-era Republicans, their anxieties were rooted in a country that seemed to be changing around them.

In the late 1840s, the United States was being flooded with immigrants, in this case from Ireland. The arrival of hundreds of thousands of poor Irish Catholics led to a rise of political groups in New York, Boston, Baltimore and Philadelphia convinced that these immigrants could form a fifth column taking direction from the Pope. Under orders from Rome, the theory went, these immigrants would undo American democracy and steal jobs from hard-working native citizens whose economic prospects were hardly secure even in the best of times.

Though these groups had actual names, such as the Order of the Star Spangled Banner, their membership at first was guarded and secretive. Asked about their views and political plans, members would reply only: “I know nothing.” The nickname was born.

Fringe movements need both oxygen and fuel. The panic over an influx of Irish-Catholics was the oxygen, and the fuel was provided by the break-up of one of the two major American political parties, the Whigs, after 1850. The Whig Party was never a coherent coalition, and when it finally cracked under the weight of North-South division over slavery, the Know Nothings suddenly emerged from the shadows to become a viable political force. 

Given that there were both Northern and Southern contingents, the Know Nothing movement avoided the issue of slavery, instead directing the passions of its supporters toward laws against drinking (the Irish were seen as overly fond of drink; they were Catholics; they were in thrall to the Pope; hence alcohol was evil); laws against immigration; laws in cities such as Chicago banning any new immigrants from municipal jobs; laws to prevent immigrants from attaining citizenship.
