Organizations of the Dune universe information

Multiple organizations of the Dune universe dominate the political, religious, and social arena of the setting of Frank Herbert's Dune series of science fiction novels, and derivative works. Set tens of thousands of years in the future, the saga chronicles a civilization which has banned computers but has also developed advanced technology and mental and physical abilities through physical training, eugenics and the use of the drug melange. Specialized groups of individuals have aligned themselves in organizations focusing on specific abilities, technology and goals. Herbert's concepts of human evolution and technology have been analyzed and deconstructed in at least one book, The Science of Dune (2008).^[1][2][3] His originating 1965 novel Dune is popularly considered one of the greatest science fiction novels of all time,^[4] and is frequently cited as the best-selling science fiction novel in history.^[4][5] Dune and its five sequels by Herbert explore the complex and multilayered interactions of politics, religion, ecology and technology, among other themes.

We've a three-point civilization: the Imperial Household balanced against the Federated Great Houses of the Landsraad, and between them, the Guild with its damnable monopoly on interstellar transport.

— Reverend Mother Gaius Helen Mohiam, Dune

As Frank Herbert's Dune (1965) begins, the known universe is ruled by Shaddam IV, the 81st Padishah Emperor of House Corrino, whose power is secured by his control of the Sardaukar, his brutally efficient military force. Imperial power is balanced by the assembly of noble houses called the Landsraad, which enforces the Great Convention's ban on the use of atomics against human targets. Though the power of House Corrino is unrivaled by any other individual House, they are in constant competition with each other for political power and stakes in the omnipresent CHOAM company, a directorship which controls the wealth of the entire Empire. The third primary power in the universe is the Spacing Guild, which monopolizes interstellar travel and banking through its proprietary use of melange-mutated Guild Navigators who perform the necessary computations to safely navigate "folded space".^[6][7]

The matriarchal Bene Gesserit possess almost superhuman physical, sensory, and deductive powers developed through years of physical and mental conditioning. While positioning themselves to serve mankind, the Bene Gesserit pursue their goal to better the human race by subtly and secretly guiding and manipulating human bloodlines and the affairs of others to serve their own purposes. "Human computers" known as Mentats have been developed and perfected to replace the capacity for logical analysis lost through the prohibition of computers. The Bene Tleilax are amoral merchants who traffic in biological and genetically engineered products such as artificial eyes, "twisted" Mentats and a type of clone called a ghola. Finally, the Ixians produce cutting-edge technology that seemingly complies with (but sometimes pushes the boundaries of) the prohibitions against computers, thinking machines and conscious robots put in place 10,000 years before as a result of the Butlerian Jihad. The doctors of the Suk School are the universe's most competent and trusted; those who have received the "Suk Imperial Conditioning" are incapable of inflicting harm. The Swordmasters of Ginaz are an elite group of master swordsmen whose fighting skills are prized and unmatched. Equally fierce in battle are the native Fremen of the desert planet Arrakis, known as Dune. Naturally honed to excellence in harsh conditions rivaling the planet on which the Imperial Sardaukar are trained, the Fremen are misunderstood and underestimated by the other powers in the universe.^[6]

Arrakis is the only natural source of the all-important spice melange, and by leading the Fremen to seize control of the planet in Dune, Paul Atreides is able to depose Shaddam and become ruler of the known universe.^[6] With a bloody jihad subsequently unleashed across the universe in Paul's name but out of his control, the Bene Gesserit, Tleilaxu, Spacing Guild and House Corrino plot to dethrone him in Dune Messiah (1969).^[8] Seeing the eventual extinction of mankind through prescient vision, in Children of Dune (1976) Paul's son Leto II devises a plan to save humanity but becomes a symbiote with the sandworm of Arrakis to gain the extended lifespan needed to see this plan to its end.^[9]

Thirty-five hundred years later in God Emperor of Dune (1981), Leto still rules the universe as a benevolent tyrant, with the help of his all-female army, the Fish Speakers. He denies any spiritual outlets other than his own compulsory religion, and maintains a tight monopoly on melange and space travel. Through his own selective breeding program among the descendants of his twin sister Ghanima, Leto finally achieves Siona, whose actions are hidden from prescient vision. He engineers his own assassination, knowing it will result in rebellion and revolt but also in an explosion in travel and colonization.^[10] The resultant chaos and severe famine on many worlds cause trillions of humans to set off into the freedom of unknown space and spread out across the universe in a diaspora later called the Scattering.

Fifteen hundred years later, as Heretics of Dune (1984) begins, the balance of power in the Empire rests among the Ixians, the Bene Gesserit and the Tleilaxu. The Spacing Guild has been forever weakened by the development of Ixian machines capable of navigation in foldspace, practically replacing Guild Navigators. Ixians are at their apex with their alliance with the Fish Speakers; but Bene Gesserit analysts see them as a failing power, because Ixian society has become a bureaucracy and no great inventions have come out of the workshops of Ix for centuries. The Bene Gesserit control the sandworms and their planet, now called Rakis, through their influence over the Rakian Priesthood that worships the sandworms as the Divided God, Leto II, and now actively participate on interstellar politics and even have their own standing armies. But the Tleilaxu have also discovered how to synthetically produce melange, and they are preparing to subjugate the rest of humanity. As a large influx of people begin to return from the Scattering, the Bene Gesserit find their match in a violent and corrupt matriarchal society known as the Honored Matres.^[11] A bitter and bloody war erupts between the orders, but in Chapterhouse: Dune (1985) it ultimately becomes clear that joining the two organizations into a single New Sisterhood with shared abilities is their best chance at survival against the approaching enemy who had driven the Honored Matres into the Old Empire.^[12]
