proditomania (uncountable)

(rare) A phobia that others are conspiring against one.
- 1897, The American Monthly Review of Reviews, The Zola Trial, page 470:
  The greedy public policy of colonizing whole continents abroad, the egotistic private practice of limiting families at home to two or three children, the prevalent politico-ritual theology, the apotheosis of the army and the infallibility of its chiefs, the defilement of literature, the prostitution of the drama and of pictorial art to the passions of the human beast, the total negation of science, the universal conviction that the nation is invincible by land and by sea, and the concomitant proditomania, combined with the cheerful certitude that France is still the light and life of the world, are inevitable consequences of the four conditions enumerated above and unerring symptoms of the dire disease which has eaten into the vitals of the citizens of the third republic.
