Missionaria Protectiva

The Missionaria Protectiva was a fictional organisation in the Dune universe created by Frank Herbert. The Missonaria Protectiva was a division of the Bene Gesserit detailed to spread certain types of religious myth and superstition among the population of the Imperium, so that the Bene Gesserit could manipulate the populance to achieve their ends.

Paul Atreides and Jessica Atreides were able to make use of these carefully planted myths among the Fremen in order to find safety after the fall of House Atreides on Arrakis. Paul Atreides indeed managed to use these myths to achieve religious leadership of the Fremen exploiting the vacuum left by the death of Liet-Kynes and used the Fremen to overthrow the Emperor of the Imperium.
