It is mentioned in Dune Messiah that Muad'Dib's jihad resulted in the "sterilization" of a number of planets.

“Very good, Stil.” Paul glanced at the reels in Korba’s hands. Korba stood with them as though he wished he could drop them and flee. “Statistics: at a conservative estimate, I’ve killed sixty-one billion, sterilized ninety planets, completely demoralized five hundred others. I’ve wiped out the followers of forty religions which had existed since—”

The question of why his followers felt the need to wage a Jihad is addressed here but I'd like to know how this particular feat (sterlising planets) was accomplished and what these poor souls did to deserve such treatment.

  • It is difficult even in the Dune Universe to "sterilize" an entire world, much less 90 worlds. I am curious if anyone has any insight into the methods used such as biological or atomics that I am not aware of, similar to the methods used in the Butlerian Jihad. Specifically this one segment of the Jihad doesn't seem to be addressed anywhere else. Perhaps its in an upcoming book? Nov 17, 2016 at 19:24

    @WilliamLedbetter it would probably be a good idea to completely change your question to reflect that you are asking HOW rather than WHY.

The how is addressed in Paul of Dune. When Muad'dib wishes to destroy a world utterly, he waves his ringed hand and his armies make it happen using all the tools at their disposal. This would appear to include conventional explosives, chemical and biological weapons , but not nuclear weapons.

A Heighliner carried one hundred of the largest and most powerful Atreides vessels, each loaded to capacity with weapons, explosives, highly toxic chemical bombs, defoliants, and wide-dispersal incendiaries.

Paul had never given such a frightening command before: Sterilize the world. Memnon Thorvald's people had to be more than defeated, more than exterminated. They must be... gone.

The Atreides ships gave no warning, engaged in no negotiations, gave no quarter to the people of Ipyr. They switched off all but their battle communications systems, so no one would hear the wails of terror, the cries for mercy or, afterward, the resounding silence. The heavily armed vessels circled down, calling up charts of every single planetary settlement, and the annihilation began.

  • @SQB - I prefer to put my book quotes in italics

  • Ah, okay, sorry about that. Since the book uses italics for the word gone, I thought to highlight that by removing them from the rest. Feel free to "crush the rollback button".

  • Thank you I had forgotten about that, I was wondering if it would be worthwhile to read Winds of Dune for clarification if it was mentioned but I'll probably stop now at least for the time being. Everything escalated so quickly in the later books its becoming hard to handle! Nov 18, 2016 at 19:13

    @Hydra119 - Killing them is insufficient. He wants to make all evidence of their existence disappear

Valorum's answer based on the non-Frank Herbert novels is certainly correct. However, I would suggest that it points out one of the many flaws in those sequel/prequels: they take things mentioned in the core books way too literally.

I doubt FH imagined Paul literally giving the order to sterilize a planet (this would be out of character even for Leto, who is much more bloody-minded). I take the passage mentioning sterilized planets to refer to Paul reflecting ruefully that the damage done by his Fremen legions pushed these planets into ecological collapse so complete they became sterile (imagine the destruction of critical terraforming equipment, or the global winter resulting from continent-wide uncontrolled fires). This would be in keeping with FH's overarching concern for ecological themes-- but admittedly does not have other textual support in the books.
