Section 31 was an officially nonexistent and uncondoned rogue agency within the Federation Starfleet that claimed to operate in the name of the security of the United Federation of Planets. Little information is available about the activities of the bureau. Those sympathetic to Section 31 assert that it was an elite intelligence and defense bureau dealing with threats to the Federation that official departments, such as the Federation Security Service or Starfleet Intelligence, either were simply not aware of, or were unable to properly confront. More hostile sources, however, claim that it was an organization dedicated merely to its own interests, regardless of whether or not said interests coincided with the interests of Federation security.

In the 22nd century, an ancestral organization within the United Earth Starfleet, also identified as "Section 31", acted covertly in the interests of United Earth. Section 31's actions were autonomous, and therefore not controlled by Starfleet Command or the Federation government.

Section 31 was actually created in advance of the Xindi attack on Earth in 2150 by an autonomous surveillance computer programme, entitled "Uraei", invented by Dresden University of Technology computer scientist, Professor Aaron Ikerson, and his graduate researcher, Lenore McGill. They showed Uraei to representatives of the four major states of Earth in 2140, who agreed to fund the programme, ultimately installing it on all Earth technology and through its activities unifying Earth. The newly-formed Starfleet would then take over funding the project, ensuring Ikerson altered Uraei to justify all actions by state consequentialism. When it learned of the impending Xindi attack on Earth, it "intended to make even such an apparent defeat work to humanity’s benefit and Earth’s eventual victory. It was already making preparations for the expansion of Starfleet, as well as the creation of Earth’s most secretive new defensive entity: Section 31." Through Uraei's installation on all Earth and later Federation technology, it spread through much of the Alpha and Beta Quadrants, forming the "Control" network and authority over Section 31. Although at times Uraei would disband Section 31, it would at times reactivate it to form a means for its extralegal activities throughout the Federation, its allies and its enemies.

The final version of Section 31 was active by the mid-24th century. From 2374, it became embroiled with Doctor Julian Bashir, a genetically engineered medical professional in Starfleet, hoping to recruit him. Ultimately Bashir, who reviled the agency, would, with the help of others including fellow augment, Sarina Douglas, Trill journalist Ozla Graniv, the Soong-type androids Data and Lal, and the free press under the Federation President Kellessar zh'Tarash, expose and prosecute fully the members of Section 31. Uraei itself was deleted by Bashir and Data. "Control", however, would embed itself further into the galactic digital fabric, having orchestrated Uraei's deletion and Section 31's public fall.


As a rogue agency, Section 31 seemed to lack an official name. It was most commonly known as "Section 31," though several agents indicated that this was not its true name; others referred to it simply as the Organization or as the Bureau. It was also known colloquially as "Thirty-One." Its true name, if any, is unknown. The name "Section 31" was first coined by United Earth Starfleet Commander Charles Tucker III in 2155 when the Bureau recruited him for a mission in Romulan space.

A Starfleet conspiracy discovered by the crew of the USS Enterprise-D in 2370 shared many of the objects and ethics of Section 31, however it is not clear whether these individuals were actually affiliated with the section or simply had a lot in common. (TNG - The Space Between comic: "An Inconvenient Truth")


According to Luther Sloan, Section 31 lacked specific headquarters, with key pieces of information being entrusted to individual agents whose knowledge of the bureau's structure remained limited. This suggested a cell-like structure often favored by terrorist groups such as the Bajoran Resistance or by intelligence agencies such as the Cardassian Union's Obsidian Order.

Section 31 was known to have maintained several secure facilities to enable its operations. In the bowels of the Federation Embassy on Qo'noS, Section 31 operated a facility in a sub-basement located beneath Starfleet Intelligence's operations center in the Embassy's basement from which it was able to spy on much of the Empire. The only way into the Thirty-One sub-basement was through special access through a single turboshaft. Klingon Imperial Intelligence was aware of the sub-basement for many years before the Federation Ambassador to the Klingon Empire, Worf used the information from II to enter the facility, exposing II's possible knowledge of the Organization's operations. Shortly thereafter, the sub-basement was completely abandoned.

Note: That Worf had assumed Section 31 director Vasily Zeitsev merely to be the "real" director of Starfleet Intelligence on Qo'noS would seem to imply that such was the extent of II's knowledge, as well.

In the 23rd century of the alternate reality, Section 31 agents, wore imposing blue and black leather outfits. Section 31 and Admiral Alexander Marcus maintained a station in orbit around Io. It was here that they initiated a militarization program for Starfleet to prepare for a inevitable war with the Klingon Empire. Despite the loss of the USS Vengeance and Khan, Section 31 had more Dreadnought-class starships equipped with more advanced cloaking devices than even the Romulans.

Section 31 also operated at least one other secure facility from which it was capable of monitoring internal and external communications from the office of the Federation President, Tezwa, and Starfleet ships. Agents of Section 31 were often observed wearing an imposing black leather outfit of a design that appeared to have been continuous from the mid-22nd century onward.



Section 31 seemed to take its name -- and justify its actions -- from Article 14, Section 31 of United Earth Starfleet's Charter, which allowed certain rules of conduct to be "bent" during times of extraordinary crisis. (ENT episode: "Divergence")

The Federation Starfleet version of the Charter incorporated a similar article which, more specifically, established an independent branch of Starfleet Intelligence that held non-specific discretionary power over non-specific matters. (TOS - Section 31 novel: Cloak)

If the Starfleet conspiracy discovered by the crew of the USS Enterprise-D in 2370 was part of Section 31, the individuals encountered claimed the conspiracy traced its roots back to the threat of alien contact perceived following the Roswell incident in the mid-20th century. (TNG - The Space Between comic: "An Inconvenient Truth")

On November 7, 1996, Brigadier General Daniel Wheeler of the decades-old, secret United States of America government department Majestic 12, vowed to himself that if the people of Earth possessed a single line of defense, then that line would begin where he stood: in Pentagon Sublevel B14, Section 31. (TOS novel: Elusive Salvation)

22nd century[]

Section 31 Agent Harris in 2154

Lieutenant Malcolm Reed of the United Earth ship Enterprise NX-01 served as an operative of Section 31's ancestral United Earth Starfleet agency early in his career under a man named Matthew Harris. Despite Reed's resignation from the bureau, Harris would later attempt to coerce Reed into returning to the organization's service in 2154. Harris ordered Reed to obstruct an investigation into the abduction of the Denobulan chief medical officer of the NX-01, Phlox, whom the organization allowed to be kidnapped and delivered to the Klingon Empire so that Phlox could search for a cure to a disease that threatened the extinction of the Klingon species. Reed was later found out, but Captain Jonathan Archer remained unable to act against the organization, of which he still knew very little. (ENT episodes: "Affliction", "Divergence")

In early 2155, the bureau agreed to provide intelligence on the terrorist agency known as Terra Prime to Reed and the NX-01 crew when Terra Prime hijacked the Verteron Array in an attempt to destroy United Earth Starfleet Headquarters and drive all non-Humans out of the Sol system. Agent Harris made it clear to Reed that this information would come at a price to be exacted later on. (ENT episodes: "Demons", "Terra Prime")

A few weeks later, Reed helped his shipmate, "Trip Tucker", get in touch with Harris when Starfleet Admiral Samuel Gardner refused to act on the threat posed by the Romulan Star Empire. After faking Tucker's death onboard Enterprise, Harris enabled to Tucker and agent Tinh Hoc Phuong to infiltrate the Empire and sabotage the Romulan program to develop a warp-7 stardrive.

Tucker was sent to the world of Adigeon Prime, where he was surgically altered to match the appearance of a Romulan scientist working on their Warp 7 stardrive project. Upon arriving in Romulan space, Tucker replaced a deceased assistant to the Romulan scientist Ehrehin, in hopes of either stealing or sabotaging the Romulan Star Empire's efforts to make a leap forward in warp technology. At the same time, Tucker discovered that the Vulcan Captain Sopek was posing as a Romulan dissident leader named Ch'uihv. During the successful attempt to rescue Dr. Ehrehin from the dissidents, Sopek murdered Tinh Hoc Phuong in cold blood before he could escape with Tucker and the doctor. Shortly afterwards, Tucker warned Starfleet of a pending Romulan attack on the world of Coridan Prime by a suicidal Romulan agent. Unfortunately, the attack succeeded, killing billions of Coridanites by igniting the planet's massive dilithium stockpiles.

Soon after, Section 31 learned of the genetic link between the Romulan and the Vulcan people, but kept the information highly classified as they feared that disclosure of this information would shatter the recently established and still-fragile Coalition of Planets. Harris soon sent Tucker back into Romulan space for further intelligence gathering from within the Empire. (ENT novel: The Good That Men Do)

Months later, Dr. Ehrehin was assassinated by the same Romulan dissident group that abducted him the first time. Agent Tucker was taken into custody by Romulan security officers, where Romulan Admiral Valdore suspected that he was actually a Vulcan agent. Believing that Tucker may still have use as an asset, Valdore sent him to the stronghold of the dissident group with Centurion Terix to discover what information the dissidents had about the Romulans' stardrive project. In the course of the mission, Terix was killed by the dissidents, and Tucker was nearly shot by the possible traitor Sopek before United Earth Starfleet officers Malcolm Reed and T'Pol arrived to rescue him. T'Pol and Reed attempted to convince Tucker to return to Coalition space, but he decided to continue his mission instead. Upon returning to Romulus, Tucker's scout ship was nearly destroyed by a Romulan Bird-of-Prey under the command of Sopek. When Tucker confronted Sopek about his true identity as a Vulcan officer, Sopek informed him that they were heading to the Gamma Hydra sector in order to protect a secret Vulcan listening post. However, upon arriving at Gamma Hydra, Tucker discovered that Sopek intended to capture Enterprise with a new Romulan telecapture device. He managed to send the Bird-of-Prey into a collision with an asteroid, foiling Sopek's plans. (ENT novel: Kobayashi Maru)

It was also known that the bureau was aware of the mirror universe at this time. (ENT novel: The Good That Men Do)

When the United Federation of Planets was founded in 2161, and a unified Starfleet was created, Article 14, Section 31 of the Earth Starfleet charter was copied unchanged to the Federation Starfleet charter. The agency continued its activities but now protecting the interests of the entire Federation. (ENT - Rise of the Federation novel: A Choice of Futures)

By the mid 2160s decade, Uraei felt Section 31 was detrimental to its goals of protecting the Federation and allowed it to be exposed. A number of operatives were arrested while Harris and his top lieutenants committed suicide before they could be arrested.

Starfleet and the Federation government decided against identifying the agency as Section 31 lest it gave the public the impression that the agency had been officially sanctioned by either the Federation or Starfleet. The 22nd century version of Section 31 thus entered the history books as "The Harris Conspiracy". Uraei then laid low, waiting for the right moment to reconstitute Section 31. (ENT - Rise of the Federation novel: Patterns of Interference)

23rd century[]

Daedalus Project[]

In the 2230s, Section 31 started Project Daedalus which involved time travel. Section 31 learned that the Klingons were looking into time travel and had one of their agents Leland steal a time crystal from the Orion outpost on Qo'noS. The crystal was sent to the Doctari Alpha. There, Mike and Gabrielle Burnham created a suit which would use the time crystal and waited for a supernova to power it for a test run. Unfortunately, the Klingons were able to track the crystal and raided Doctari Alpha's research facility. During the attack, the Burnhams hid their daughter Michael in a cabinet. Her father was killed quickly and the Klingons supposedly took their time with her mother. Only their daughter survived and the project was believed to have been lost. (DIS episodes: "The Red Angel", "Perpetual Infinity")

In 2257, following a cease fire between the Federation and Klingon Empire after the War of 2256, one of their agents, Leland was sent to Qo'noS. There, he approached former Terran Empress, Philippa Georgiou, now owner of a Orion Cabaret. There, Leland offered her a position with Section 31. Later, Georgiou recruited Ash Tyler after ensuring L'Rell's continuation as the Klingon High Council's Chancellor. (DIS episode: "Will You Take My Hand?" (bonus scene)"; DIS reference: Star Trek: Discovery - The Official Companion)

Control malfunction[]

During this time, Section 31 learned about a entity known as the "Red Angel" was using the Daedalus Project's suit. The USS Discovery under Captain Christopher Pike worked with Section 31 in discovering that the Red Angel was behind the seven Red bursts. (DIS episodes: "Project Daedalus", "The Red Angel")

In the early 2260s, Section 31 recruited twenty-year Starfleet security officer Peter Lawrence into their ranks. Lawrence, who had been dreading the thought of retirement or a desk job, jumped at the chance to continue to serve. Working for Section 31, Lawrence found that he had a talent for investigative matters, but became uncomfortable with the secrecy and paranoia that fueled every action of the agency.

Lawrence left Section 31 after he investigated attorney Samuel T. Cogley at their behest. The bureau believed that Cogley had an agenda that ran counter to the security needs of the Federation, and Lawrence was assigned to discover this agenda. He discovered, however, that Cogley had no agenda, simply a firm conviction that all beings were entitled to the best possible defense in a court of law. Lawrence, believing Cogley to be the single most honorable man that he had ever met, resigned from Starfleet to work for Cogley.

Section 31 attempted to coerce Lawrence into reconsidering, and returning to duty. He refused vehemently, leaving the Bureau for good, with both his life and reputation intact. (TOS novel: "The Case of the Colonist's Corpse")

The Omega Molecule and the Lantaru Disaster[]

In 2268, Captain James T. Kirk of the USS Enterprise was assigned by Rear Admiral Lance Cartwright to retrieve a Romulan cloaking device at all costs. The mission was successful. Following that mission, Captain Kirk was then given the assignment to test the cloaking device on the Enterprise.

Several months later, evidence linking the "liberated" cloaking device to the destruction of the USS Sphinx with all hands was uncovered by the crew of the Enterprise. Inquiries to Cartwright proved a dead-end, and Captain Kirk decided to investigate further, uncovering both the existence of Section 31 itself and of a cabal of rogue scientists supported by the Organization that was trying to create a stable Omega molecule. The scientists' unsuccessful attempt at creating a stable Omega molecule resulted in the destruction of the subspace layer for several cubic lightyears throughout the Lantaru sector, rendering warp travel impossible in that area. This event led Starfleet to impose the Omega Directive, barring all Omega research.

Two months later on a remote planet, Kirk met with Captains Phil Waterson and Nick Silver, and Commodores Aaron Stone and José Mendez to inform them of his discoveries and suspicions. They formed a secret cabal whose purpose was to oppose Section 31 wherever it reared its head.

The Kirk Cabal took in new members in the years that followed, and still existed in 2376 when Commander Elias Vaughn recruited Dr. Julian Bashir into its ranks. In 2377 on stardate 54973.4, Typhuss James Halliwell joined the Kirk Cabal.

In 2270, Section 31 sent an operative, Moore and another man to get a security disk for Archenar IV's High Administrator's chamber from his son. They promised the High Administrator's son that they would eliminate the High Administrator so that his people would not join the Federation. However, Section 31 wanted their world to join the Federation. Moored and compatriot then murdered the High Administrator's son and his guard. Moore then killed his compatriot. He was then assigned to the Enterprise. On board the Enterprise, Moore then secretly contacted Orion Syndicate leader Marikk Botar and gave him Archenar IV's coordinates to him. The Orion Syndicate hoped to obtain the weapon and power of Archenar IV for their use. Moore's message was discovered by Lt. Uhura. Commander Scott and Lt. Sulu found and took him to the ship's brig.

Admiral Cartwright

In 2293, Admiral Cartwright was part of a conspiracy to assassinate Klingon Chancellor Gorkon, Son of Toq, and Federation President Ra-ghoratreii in collusion with Klingon General Chang, Romulan Ambassador Nanclus, Federation Starfleet Colonel Patrick West, Lieutenant Valeris, Yeomen Burke and Samno, the commandant of Rura Penthe and a prisoner there named Martia. The conspiracy's goal was to undermine the peace process and ignite a war between the Empire and the Federation that each side's members in the conspiracy believed their nation destined to win.

Given Cartwright's prior history with Section 31, some have speculated that this was also a Section 31 operation, although no evidence has surfaced to confirm this.

One of Cartwright's co-conspirators was future Starfleet Commander-in-Chief Admiral Androvar Drake. It remains unclear, however, whether or not Drake had any knowledge of Cartwright's deeper ties to Section 31.

Kelvin timeline[]

From 2239 until 2259 of the Kelvin timeline, Section 31 agents covertly supplied Captain Robert April with Starfleet arms and technology through the trader Mudd to help the Phaedan rebellion. The plan was for April to distract the Klingon Empire. Section 31 associate Admiral Alexander Marcus, also ensured that his control program would be installed in the new USS Enterprise and gave the orders for Captain James T. Kirk to do a survey of Phaedus IV so that April could take it and give it to the Klingons to make him governor of Phaedus.

During this time, Section 31 attempted to recruit Hikaru Sulu into ranks but he refused in favor of serving aboard the USS Enterprise. However, they were able to recruit his sister, Yuki Sulu after she lost her friend, T'Pan when Vulcan was destroyed.

In The Return of the Archons story, it was suspected that Section 31 and it's associate, Alexander Marcus kept the experiment secret. It is unclear if Section 31 was behind the cover-up.

Following the destruction of Vulcan , Section 31 sought ways to militarize Starfleet to defend the Federation as its associates such as Admiral Alexander Marcus foresaw war with the Klingon Empire. Section 31 began exploring more direct means of defense and explored unknown regions of space. During this time, one of their ships, the USS Vanguard, found the SS Botany Bay and thawed out Khan Noonien Singh. They then did facial reconstruction on him to give him a Northern European look, altered his vocal cords and recruited him under the name John Harrison, a Starfleet London Archive researcher. In that capacity, Khan designed weapons and ships such as the USS Vengeance. He was also sent on missions, such as to destroy the Klingon moon of Praxis. During this time Section 31 had a secret facility in London, officially known as the Kelvin Memorial Archive. When Khan's memory returned to him, he tried to force Marcus to give him his crew. Marcus refused and threatened to eliminate them. Khan then disappeared. Khan, believing Marcus had his crew killed, coerced Thomas Harewood into a suicide bombing of the London Archive.

Following the apprehension of "John Harrison" and Robert April, Starfleet began an comprehensive effort to remove all elements of Section 31 that Admiral Marcus operated. Despite Starfleet's efforts, Section 31 continued to secretly plot to ignite war between the Romulans and Klingons using contingency plans devised by Marcus before his death. However, a few of their agents believed that Marcus's actions had set the section's work for years.Section 31 sent a few of their operatives to Romulus to speak to the Romulan Senate. Section 31 promised they would help them in wiping the Klingon Empire from the stars. They told the senate that Starfleet may have abdicated its responsibility to protect Earth and the Federation but Section 31 has not. However the Romulans were suspicious of section 31 if they could deliver the technology to help them with Klingons, knowing that they wanted the red matter. Despite that, Section 31 were able to arrange a rendezvous near Khitomer in anticipation of the Klingon's new fleet heading towards Orion. However, Section 31 decided to wait till the time was right to reveal everything. Section 31 also carried Khan Noonien Singh and his 72 other augments on one of their ships.

The Khitomer Conflict[]

"Spear 31" team assaulting Qo'nos in 2261

Section 31 were also able to provide the Romulan's attack force under L'Nar with advanced weaponry used on the Vengeance that were more than a match against the Klingons when they attacked their colony on Khitomer. L'Nar was then contacted by a human Section 31 operative, who assured them that the Klingon would have no choice but to retaliate against the Romulans with the bulk of their fleet. He also said that they would crush the klingons together. He then ordered L'Nar to rejoin the Romulan fleet at the Hectori system while they drew Klingons to Khitomer. He assured L'Nar that after the Klingon Empire falls, it would benefit both their species.

Section 31 then met up with Commander L'Nar near the Klingon/Romulan border where their ships were able to to move in on them undetected. Together, both Section 31's and L'Nar's forces decided to attack Qo'nos to "permanently" stop the threat of the Klingon's aggression. When they arrived, theirs and L'Nar's ships opened fired on all of Qo'nos's main cities. Section 31 then sent their "Spear 31" assault team to kill anyone who they saw as a threat. Section 31 then made sure L'nar would keep his word not harm Captain Kirk or his landing party. Kirk and his crew were then returned to the Enterprise. However, Kirk and his landing party then returned to stop Section 31 from using the Romulan's red matter in wiping the Klingons out. Though Kirk and his party were able to subdue most of the agents, they were then held at gunpoint by Yuki Sulu, who revealed herself as a agent of Section 31.

Section 31 and the Romulans then held the Chancellor, and High Council as they prepared to detonate the red matter to destroy the First City. However, Section 31 was double-crossed the Romulans and took the red matter. Unbeknown to L'Nar, Section 31 also installed a self-destruct program onto the modified warbirds, which they destroyed. Section 31 had accomplished their goals; they had the Klingon and Romulan fleet cut to pieces, the red matter in their possession, and assurances that the Klingons would retaliate against the Romulans, all to the Federation's's advantage. The Section 31 operative in charge then allowed Kirk and his party to return to the Enterprise. Yuki Sulu, the other agents and their ships then disappeared without a trace on any sensors.

The 24th century[]

The Tzenkethi[]

During the conflict with the Tzenkethi Coalition, Section 31 gave the location of the USS Leonov to the Tzenkethi when they discovered that the Leonov was about to receive orders to attack a civilian target based on bad intelligence. The Leonov was destroyed, and over half of her crew lost. Section 31 believed that the loss of the Leonov was justified if it kept the Tzenkethi from escalating the conflict.

The agent that leaked the information to the Tzenkethi was eventually tracked down by the Leonov's former second officer, William Ross. The agent told Ross his side of the story, and Section 31's belief that what they had done was for the good of the Federation. Ross made the decision not to turn the man over to the authorities, and Ross would work with Section 31 at various points in his career.

Chiaros IV[]

In early 2373, Section 31 agents Ambassador Aubin Tabor and Starfleet officer Commander Cortin Zweller were given the task of making sure that the people of the world of Chiaro voted to join the Romulan Star Empire rather than the United Federation of Planets. Chiaros was the only inhabited planet in the vast expanse of space known as the Geminus Gulf. Section 31 felt that the Federation would waste too much time and resources defending a strategically worthless planet, so they agreed to give the planet to Romulus in exchange for a list of Tal Shiar spies working inside the Federation.

What Section 31 did not realize was that the Romulans had discovered a sub-space singularity, a potential source of tremendous energy, near the Chiaros system - an energy source that Section 31 had inadvertently handed to the Romulans. Starfleet Vice Admiral Marta Batanides, a major leader in Starfleet Intelligence, Captain Jean-Luc Picard, and Lieutenant Sean Hawk (both of the USS Enterprise-E discovered Thirty-One's existence, the details of its plan, and the existence of the sub-space singularity. Batanides and Picard allowed Zweller to complete his mission, but took him into custody thereafter. At the same time, Picard, Commander Data, and Lieutenant Sean Hawk embarked on a successful mission in a stolen scout ship to destroy the singularity, and rob the Romulans of their prize.

Zweller was cleared of all charges and released on the order of Admiral Connaught Rossa, despite the objections of Batanides and Picard. Batanides swore to use all of the resources at her disposal to bring down Section 31.

Typhuss James Halliwell[]

In 2371, Agent Sloan attempted to recruit Lieutenant Typhuss James Halliwell into the ranks of the bureau shortly before Voyager's mission to the Badlands. Sloan revealed the truth of Thirty-One to Typhuss. Typhuss was horrified to learn of the existence of an organization within Starfleet that made their own agenda and answered to nobody, and refused Sloan's offer. (Star Trek: Intrepid episode: "Section 31")

USS Voyager[]

In 2371, Section 31 agent Luther Sloan assigned operative Roberta Luke to the sciences division of the USS Voyager shortly before its mission to the Badlands in order to gain intelligence on the Maquis.

Luke was onboard when Voyager was transported to the Delta Quadrant by the Nacene known as the Caretaker. Luke maintained her cover and kept a log of events for her superiors in Section 31.

When Captain Kathryn Janeway took in the disconnected Borg drone known as Seven of Nine as a member of the crew in early 2374, Luke decided to take action. Believing Seven's presence to be a tremendous mistake on Janeway's part, Luke reprogrammed one of the ship's spare bio-neural gel packs with instructions for the ship's computer to kill Seven and make it appear to be an accident.

She nearly finished programming the pack, but was killed before she could install it. Eighteen months later, ship's chief engineer B'Elanna Torres swapped out a defective pack with Luke's tainted one, and the ship's computer commenced with its attempts to kill the former Borg drone.

When the re-programming was discovered, Seven recognized the coding as one used only by the covert agency. Seven had gained knowledge of Section 31 when she was in the Collective and an operative of the bureau had been assimilated, granting all of his knowledge to the Borg Collective. The reprogramming was reversed when the ship's Emergency Medical Hologram, known as the Doctor, developed a bio-neural "vaccine" that re-programmed the ship's computer to resume its normal function.

Julian Bashir[]

Luther Sloan in 2374

In 2374, Agent Sloan attempted to recruit Dr. Julian Bashir, the genetically enhanced chief medical officer of Starbase Deep Space 9, into the ranks of the bureau. He had Bashir abducted prior to a trip to attend a medical conference and transported aboard the holodeck of an unknown Intrepid class starship, which then recreated his life on DS9. Posing within the holoprogram as the Deputy Director of Starfleet Internal Affairs, Sloan tested Bashir's loyalty to the Federation by accusing him of treason, arguing Bashir to be a Dominion sleeper agent. When Bashir proved that his loyalty to the Federation was above reproach, Sloan revealed the truth of Thirty-One to the doctor.

Section 31 operatives in 2374

Bashir was horrified to learn of the existence of an organization within Starfleet that made their own agenda and answered to nobody, and refused Sloan's offer. Despite Bashir's refusal, Sloan continued to consider Bashir as an asset. Bashir, meanwhile, reported his experience to his commanding officer, Captain Benjamin Sisko, and to the rest of the station's senior staff (including two members of the allied Republic of Bajor's Militia, Kira Nerys and Odo). Sisko ordered Bashir to agree to join Thirty-One the next time he had the chance.

Luther Sloan in 2375

In 2375, Agent Sloan contacted Bashir for a mission during an upcoming conference on Romulus between the Federation and Romulan Star Empire. Sloan manipulated Bashir into believing that he intended to assassinate Koval, Chair of the Tal Shiar, the feared Romulan secret police. Bashir, acting on this belief, convinced Romulan Senator Kimara Cretak to access Koval's personal database in order to discover who would be acting to aide Sloan; Cretak was then arrested and tried before the Romulan Continuing Committee, and found guilty of treason. During the trial, Bashir was also interrogated, and Koval and Sloan conspired to provide false evidence to the Committee that Thirty-One did not exist and had been created by Sloan to manipulate Bashir. In actuality, the goal of Section 31 was to ruin the career of Senator Cretak, who had previously proven herself willing to risk the stability of the alliance against the Dominion in the perceived interests of the Empire, and install Koval, who had become a mole for Section 31, onto the Continuing Committee in Cretak's place. Their plan succeeded.

In 2375, Dr. Bashir deduced that Section 31 had engineered a virus that threatened to wipe out the entire species of the shape-shifting Founders. Bashir, along with DS9's Chief of Operations Miles O'Brien, set a trap for Sloan in order to find a cure for the virus. Sloan chose suicide over capture, and Bashir was forced to resort to extreme measures to get the information directly from Sloan's brain before he died.

The Son'a[]

Admiral Matthew Dougherty

In mid-2375, Admiral Matthew Dougherty worked with the Son'a on a project on a world located within the area of space known as the Briar Patch, despite the fact that the Son'a had been supplying Ketracel white to the Dominion. This alliance was attempting to forcibly relocate the local population of Bak'u from the world in order to transform it into a source of regenerative energy.

The operation was brought to a halt by Jean-Luc Picard and the Enterprise-E. Admiral Dougherty, who was killed by his Son'a "allies," took the fall and was branded as a rogue. Though Section 31 was never implicated, however, the cloaking-capable ship with a holographic interior, known as the Holoship, created to facilitate the plot came into the hands of the Kirk Cabal, who would come to suspect the organization's involvement in the matter.


In April of 2376, Bashir was again contacted by Section 31, this time in form of a man named Cole. Cole informed Bashir of a failed Section 31 operation on the world of Sindorin in the Badlands designed to breed a new strain of Jem'Hadar soldiers that would be loyal to the Organization. The project went awry when Section 31's chief scientist on the project, a genetically enhanced doctor named Ethan Locken, betrayed his benefactors and used the project for his own plans of conquest. Cole believed that Bashir, due to his genetically enhanced nature, was the best choice to bring Locken in. Bashir accepted the assignment.

Bashir, along with Lieutenants Ezri Dax and Ro Laren and the Jem'Hadar observer, Taran'atar, journeyed to Sindorin and confronted Locken and his loyal Jem'Hadar. In the end, Locken's own flawed Jem'Hadar turned against him, killing him. Bashir also theorized that Section 31, in an attempt to drive Locken to the heights of desperation and rage it felt would be necessary for him to agree to join the bureau, may have intentionally leaked information to the Dominion during the war, arranging for the New Beijing Massacre that claimed thousands of civilian lives. This theory was based purely on circumstantial evidence, involving Bashir's discovery that Cole had gone undercover as Locken's friend and mentor on New Beijing, as well as Bashir's general contempt for Section 31.

Upon returning to the station, Commander Elias Vaughn, who had long struggled against Section 31 during his lengthy Starfleet career, recruited Bashir into the elite, secret cabal created by Captain Kirk to counteract the organization.

Min Zife and Tezwa[]

In 2379, Section 31's chief agent on Qo'noS, Vasily Zeitsev, assisted Ambassador Worf in obtaining command codes for the Klingon fleet threatening to invade Tezwa. Tezwa had become a flashpoint of galactic events when the mad Tezwan leader Kinchawn attacked the Klingon Empire with Nadion-pulse cannons obtained illegally through the office of Federation President Min Zife. Zife had assigned Jean-Luc Picard of the USS Enterprise to bring the planet under Federation jurisdiction in order to hide the origins of the cannons from the Klingons, not informing Picard or Starfleet of the cannons' origins. Picard asked Ambassador Worf to obtain the fleets command codes, and in order to prevent war with the Klingon Empire. Zeitsev, not correcting the ambassador's mistaken belief that he was a high-ranking officer in Starfleet Intelligence, assisted Worf in obtaining them. Unbeknownst to all involved, Zeitsev and his colleagues at the Organization had every intention of remotely triggering a number of high-yield bombs capable of destroying the entire planet if Picard's crew failed in their mission. Section 31 then intervened when Koll Azernal, Zife's chief of staff, attempted to plant evidence framing the Tholian Assembly for the cannons' origins, alerting Starfleet to the deception and ordering a sleeper agent to kill the crew of an Orion Syndicate merchantman. Zife's actions had brought the Federation to the brink of war with the Klingons, and Section 31 felt that Zife could not be allowed to ever speak of the events of Tezwa.

Section 31 contacted Admiral William Ross, and detailed their plans for Zife and his staff. Ross had come to an agreement with Captain Picard, Federation Ambassador to Tezwa Lagan Serra, and Admirals Alynna Nechayev, Mamoru Nakamura, Owen Paris, and Edward Jellico, to force Zife, Azernal, and Federation Secretary of Military Intelligence Nelino Quafina (who had facilitated the cannons' transportation) out of office prior to his contact with Thirty-One; the plan was simply to have the trio placed in protective custody, but the bureau had other plans for them.

Ross, Nechayev, and Nakamura, using their authority over Starfleet Security (the agency charged with protecting the President and the Palais de la Concorde), forced Zife, Azernal, and Quafina to join them in the Palais de la Concorde Monet Room and had the building cleared of security personnel. There, the admirals confronted Zife and forced them to resign. Upon agreeing, a Vulcan Section 31 agent named L'Haan entered the Monet Room with three other operatives; claiming to be Starfleet officers who would transport the President to protective custody, L'Haan was instantly recognized as an agent of the Bureau by the admirals, Azernal, and Quafina; only President Zife, it seems, had never heard of the rogue organization. L'Haan had Zife read a prepared statement announcing his resignation on live telecommunications from the Presidential Office.

After the speech, L'Haan and her agents executed President Zife, Chief of Staff Azernal, and Secretary Quafina. Eventually, reporter Ozla Graniv of the Trill news magazine Seeker discovered the that the Federation had given Tezwa the pulse-cannons and that Admiral Ross had forced President Zife, Azernal, and Quafina to resign. In exchange for not publishing this information, Graniv demanded that Ross step down. Only President Nanietta Bacco was able to deduce that Zife had been killed rather than simply forced to resign -- however, she mistakenly believed Ross to have been the assassin. Ross did not inform President Bacco or anyone else of the true identity of President Zife's killers, believing that the bureau would kill her just as ruthlessly as it had Zife if she were to discover the truth.

25th century[]

The existence and activities of Section 31 were exposed to the general public by the early 25th century, and its agents were forced to stand trial for their actions. It was believed that the public release of Section 31's files and records ended over 300 years of the bureau's unsanctioned black-ops and infiltration programs. Despite this, it was uncertain if the agency's existence ended completely.

The events illustrated above appear to be contradicted by the Star Trek Online timeline, as Section 31 continues to exist well into 2410. And despite some transparency among the upper echelons of Starfleet, much of Section 31's operations remain unknown to the majority of the general public. Section 31 tests player characters on a mission in a fashion similar to that of Dr. Julian Bashir. A Section 31 agent, Franklin Drake, also enlists the player's aid in several other missions. When Devidians start haunting the Klingon Neutral Zone, Section 31 assists the player in stopping them.
