Evidence

During the Dreyfus crisis each was able to exploit this popular notion by hurling at the other charges of conspiring to world domination. The slogan, “secret Judah,” is due, no doubt, to the inventiveness of certain Jesuits, who chose to see in the first Zionist Congress (1897) the core of a Jewish world conspiracy. Similarly, the concept of “secret Rome” is due to the anticlerical Freemasons and perhaps to the indiscriminate slanders of some Jews as well. — Hannah Arendt, The Origins of Totalitarianism, 311
