... A manifesto signed in 1895 by a number of leaders of the Populist party:
As early as 1865–66 a conspiracy was entered into between the gold gamblers of Europe and America. . . .
For nearly thirty years these conspirators have kept the people quarreling over less important matters while they have pursued with unrelenting zeal their one central purpose. . . .
Every device of treachery, every resource of statecraft, and every artifice known to the secret cabals of the international gold ring are being used to deal a blow to the prosperity of the people and the financial and commercial independence of the country.
Next, a Texas newspaper article of 1855:
. . . It is a notorious fact that the Monarchs of Europe and the Pope of Rome are at this very moment plotting our destruction and threatening the extinction of our political, civil, and religious institutions. We have the best reasons for believing that corruption has found its way into our Executive Chamber, and that our Executive head is tainted with the infectious venom of Catholicism. . . .
The Pope has recently sent his ambassador of state to this country on a secret commission, the effect of which is an extraordinary boldness of the Catholic church throughout the United States. . . .
These minions of the Pope are boldly insulting our Senators; reprimanding our Statesmen; propagating the adulterous union of Church and State; abusing with foul calumny all governments but Catholic, and spewing out the bitterest execrations on all Protestantism.
The Catholics in the United States receive from abroad more than $200,000 annually for the propagation of their creed. Add to this the vast revenues collected here. . . .
These quotations give the keynote of the style.
In the history of the United States one find it, for example, in the anti-Masonic movement, the nativist and anti-Catholic movement, in certain spokesmen of abolitionism who regarded the United States as being in the grip of a slaveholders’ conspiracy, in many alarmists about the Mormons, in some Greenback and Populist writers who constructed a great conspiracy of international bankers, in the exposure of a munitions makers’ conspiracy of World War I, in the popular left-wing press, in the contemporary American right wing, and on both sides of the race controversy today, among White Citizens’ Councils and Black Muslims.
I do not propose to try to trace the variations of the paranoid style that can be found in all these movements, but will confine myself to a few leading episodes in our past history in which the style emerged in full and archetypal splendor. ... http://harpers.org/archive/1964/11/the-paranoid-style-in-american-politics
