element in the evolution of humanity and many of the major plot developments.


The origins of the Bene Gesserit are not widely known. What is clear is that the Bene Gesserit arose in the political turmoil that followed the Butlerian Jihad, and quickly established themselves as an influential political force. However, during the Butlerian Jihad, the Bene Gesserit already had a Mother Superior, which seems to show that their hierarchical structure had already formed.[1]

The other memories that are made available to Reverend Mothers of the Bene Gesserit provided a wealth of knowledge that reaches far back into Humanity's past, to the days when Humans were bound to Earth. Some physical remnants, such as a surviving painting by Van Gogh, also support this connection and provide an anchor point to the distant past.

Objectives of the Bene Gesserit

The primary objective of the Bene Gesserit was to attain further power and influence and help to direct humanity along a path of insight and stability. Up until the emergence of Leto Atreides II, the anticipated means of reaching this goal was through the Kwisatz Haderach - the one who can be all places at once (a male Bene Gesserit "Mother Superior", a "super-being", and ultimately a messiah figure to serve the Missionaria Protectiva), and the ultimate objective of their age-old breeding program. The triumph of their plan was supposed to occur when the daughter of Leto Atreides I bred with Feyd Rautha Harkonnen.

However, their plans were thrown into turmoil by Jessica Atreides, when she consciously gave Leto Atreides I a son (Paul Atreides) instead of a daughter. Paul was assumed the Kwisatz Haderach, and, much to the dismay of the Bene Gesserit, arrived a generation too soon. Whether the order could have fully controlled the Kwisatz Haderach as they hoped remains debatable.

The Bene Gesserit’s plans are further disrupted when Paul bred with Chani, the Fremen daughter of Liet Kynes, stirring up rogue and unpredictable genetic traits. Their son, Leto Atreides II, and his actions as the God-Emperor, radically altered the long-term destiny of the Bene Gesserit: their primary goal became the re-establishment of their power-base, an intention that was severely tested by the emergence of the Honored Matres.

This objective was largely met, thanks to the merger of the Bene Gesserit and the Honored Matres but it remained clear that their fate is still very much out of their own hands.

Structure of the Bene Gesserit

Women unquestionably ruled the Bene Gesserit, and while men did maintain some important roles, they were always answerable to at least one woman - the Bene Gesserit Mother Superior.

The Mother Superior: maintained ultimate control of the entire order, and invoked almost unquestioned loyalty among the subordinate Reverend Mothers. A Reverend Mother chooses her successor prior to her death, and imparts her memories and personality to her. The inheritance of the Mother Superiors, at times, diverged among multiple Reverend Mothers, usually for strategic reasons.

Kwisatz Mother: possessed the strongest tie to the other voices, in charge of the program to breed the Kwisatz Haderach; She solely directed the breeding program.

The subordinate Reverend Mothers of the Bene Gesserit fulfilled many diverse roles, including intelligence gathering, diplomacy, and breeding to continue the objectives of the breeding program. They also pursued more menial roles, with their occupation determined by the quality of their genetic make-up.

  • Reverend Mothers: Have undergone the Spice Agony and survived. They fill the role of advisors, faculty, historians, geneticists. General authority of the Order for most members and the outside populace.
Proctor Superiors: In charge of a chapter house, each chapter house has a Proctor Superior.
Truthsayer: taught the ways to invoke the truth trance.
Sister: agents, concubines, potential wives.

Powers and Abilities

The Bene Gesserit schools were designed to maximise the physical and mental potential of humanity, especially females. As a result, Bene Gesserit adepts possessed abilities that could not be rivalled by anyone else in the known universe.

Physically, a Bene Gesserit could control every muscle and nerve in their body, right down to the individual fibers. They were supreme in the disciplines of prana and bindu. The results of this training were numerous abilities, including:

  • Oral Analysis: Upon tasting an item, a Bene Gesserit can break down the food into its ingredients, right down to its chemical composition;
  • Internal Organic-Chemical Control: Alteration of metabolism to render poisons harmless. This ability was used when potential Reverend Mothers took the Water of Life;
  • Prana Bindu: Alteration of blood flow, body temperature, heart rate, and level of consciousness, for the purposes of survival in harsh environments, or escaping from bonds;
  • Weirding Way: Superior hand-to-hand combat abilities; martial arts. Bene Gesserit trained men and women unrivalled in their fighting abilities. Only Imperial Sardaukar and the Fremen of Arrakis could approach the abilities of a Bene Gesserit in regards to combat techniques, attack speed, and resourcefulness. Later, in the Age of The Tyrant, and even later, in the times after The Scattering, new abilities were developed in humans by means of genetic breeding, in extremis situations (see Miles Teg, a Bene Gesserit Bashar), or designed into ghola abilities (see "Heretics Of Dune" era Duncan Idaho).
  • The Voice: Ability to influence people directly by giving them orders with a certain sound frequency. When a person is ordered to do something by the use of Voice it is almost irresistable not to comply. A Bene Gesserit is trained to resist the Voice. The downside of it is the phenomenon of entire population becoming immune to it if The Voice is being overly used upon a population. Mentats can especially become immune to the Voice if he understands how it works.
  • Sensing the Truth: Truthsayer is trained to sense if someone is telling the truth or not, but the other Bene Gesserit can also spot if someone is holding something back. Example: When Dr.Yueh was supposed to betray the Duke Leto of the Atreides, he felt guilty and anxious about it. Jessica had conversations with him and sensed that he is holding something back. Being informend that Bene Gesserit can sense his guilt about what he was about to do he exploited/manipulated his own emotions (remembering his wife in the grasp of baron Harkonnen) and mentioning her every time he thought Jessica was studying him and searching for more reasons why he felt so disturbed.

Bene Gesserit mental abilities included supreme levels of discipline. A Bene Gesserit mind could alter its level of consciousness, for the sake of relaxation, and hyper-alertness in times of potential danger. Moreover, a Bene Gesserit trained individual could:

  • Petit Perception: monitor minutiae in others to detect concealed emotions, motivations, agendas, or even physical things such as concealed weapons, a false accent, surgery, or deception in general. This particular skill was useful in detecting face dancers.

Emergence as a Universal Power

"She nodded. "We have two chief survivors of those ancient schools: the Bene Gesserit and the Spacing Guild. The Guild, so we think, emphasizes almost pure mathematics. Bene Gesserit performs another function." "Politics!" he said. "
Reverend Mother Gaius Helen Mohiam[src]

For millennia, the Bene Gesserit Sisterhood chose to exercise its power by acting in the background of imperial politics. Through their breeding program, their placement of agents in the imperial court and Great Houses, and their provision of services such as the training of noble females, mediation in disputes, and overseers of negotiations, the Bene Gesserit carved out a significant niche in the structure of the Imperium. They were also silent partners in CHOAM along with the Bene Tleilax.

This all changed when House Atreides wrested the imperial throne from House Corrino. After the reign of Paul Atreides and his son Leto Atreides II, there came into existence a power vacuum. This vacuum was filled by both the Bene Gesserit and Bene Tleilax, who sought to maintain control over the remnants of the empire after humanity exploded across the universe in The Scattering. The Bene Gesserit came to believe that if they were to avoid coming under another tyrant, they would have to take a more active role in politics and universal events.

The Honored Matres

It came to the point where the Bene Gesserit came to open conflict with both the Bene Tleilax and the Honored Matres, a bastardisation of Bene Gesserit + Fish Speakers that returned from The Scattering. Indeed, the Sisterhood found themselves in a position of champion of the Old Order when the Honored Matres began attacking planets of the Old Imperium.

During the Return of the Honored Matres, the Gesserit Mother Superior Darwi Odrade, a descendant of Paul, realized only through the Sisterhood combining with the Matres could both organizations survive into the future. First, Odrade trained her captive Murbella, a captured Matre, in the ways of the sisters. Then she and a ghola of Miles Teg, set up a plan to attack the Honored Matre base on the Guild-world of Junction. As Odrade was killed in the ensuing battle, Murbella also killed the Honored Matre leader, Logno. Murbella then decided to unite both groups into the New Sisterhood.

Sheeana Escapes

There was immediate resistance to the concept of the merger, as Sheeana, a rebel Reverend Mother, escaped from Chapterhouse in a No-ship, with a hundred of her fellow sisters; taking a few sandworms with them. They escaped with Miles Teg and Duncan Idaho, who had their own reasons for leaving; but Sheeana's group's intention was one to set up a "pure" Gesserit outpost, far away from civilization. As the no-ship fold-spaced throughout the cosmos in an attempt to escape the tachyon net of the mysterious elderly couple, Daniel and Marty, the sisters aboard the no-ship held true to their training and structure.

Behind the Scenes

Frank Herbert may have chosen the name "Bene Gesserit" with a very concrete meaning in mind, but the name is at least somewhat ambiguous, perhaps intentionally.

On one level, "Bene Gesserit" is an unadulterated Latin sentence (or motto). Yet because of the way Latin works, it is difficult to translate without more context. The verb gero, gerere (of which gesserit is a form) can mean a wide variety of seemingly unconnected things: bear, manage, wear. Translations of the whole expression can mean "[he/she/it] will have born/managed/worn [something] well," or then also more idiomatically it can mean thigs like "[he/she/it] shall have behaved well." An interpretation having something to do with bearing children would suitably match the breeding mission of the Bene Gesserit, but the phrase could suggest many other things as well.

The name can also be interpreted as a Hebrew derivative. "B'nei" (בני) means 'children of' (e.g. Bene Tleilax) and "Gesher" (גשר) means 'bridge.' Another interpretation could be "Gesserit" as derived from "jesherun," or "just," meaning "Chidren of the Just."

Brian Herbert speculates that "Gesserit" is most likely a derivative of the word "Jesuit", an order of priests still active today. "Jesuit" also has the connotation of someone given to intrigue or mystique. Therefore the name "Bene Gesserit" can be rationally surmised to mean a society of religious peoples who, while being secretive or clandestine, also function for the good of the society they inhabit.
