Federation history

The history of the United Federation of Planets is the tale of an extraordinary interstellar alliance, slowly forged from the convergence of Human, Vulcan, Tellarite, and Andorian histories, and those of its other member species.
== 21st century ==
Rising from the ashes of World War III, the seeds of the Federation were brought forth in 2063, when Doctor Zefram Cochrane created Earth's first warp-capable ship, the Phoenix. Zefram Cochrane's historic flight attracted a passing Vulcan ship, the . This event, known as First Contact, occurred on April 5, 2063, and not only led the Vulcans to assist Humanity to eradicate poverty, disease, and the causes thereof by the 2110s, but also brought the nations of Earth to unite the entire planet under a United Earth Government by 2150. In an alternate timeline created by the Borg traveling back in time, this event occurred slightly differently. Though in this timeline the Borg had traveled back in time to prevent its launch and assimilate Earth, thanks to the efforts of the , Cochrane was able to make his historic flight. (; ; ; )
In several alternate timelines in which Earth history had been changed earlier than 2063, the Federation did not form as it actually occurred. This included a timeline in which Nazi Germany won World War II and another one in which Gabriel Bell did not intervene during the Bell Riots. (; )
==22nd century==
===Humanity enters the galactic stage===
Although Earth's initial warp development progressed slowly, due to the caution of their Vulcan "mentors", the Warp Five program proceeded steadily, with major milestones being the inauguration of the Warp Five Complex in 2119 and achieving warp 2.5 in 2143. Earth's first warp five ship, , commanded by Captain Jonathan Archer, was launched in 2151, heralding a new era defined by encountering numerous new species, like the Andorians, and initiating those friendships which eventually led to the Federation. ()
===Turmoil on Vulcan===
The Vulcan Reformation of 2154 represented another pivotal step towards an interstellar union, prompting a new willingness on 's part to engage in closer collaboration with neighboring species, including Humans and Andorians. When the United Earth Embassy on Vulcan fell victim to a terrorist attack, the Syrrannites, a group of Vulcans who believed their race had lost their interpretation of Surak's teachings, were initially blamed. As Archer learned, however, this was just an elaborate attempt by the Romulan-influenced Vulcan High Command to round up the Syrannites as well as to launch a preemptive strike on Andoria based on falsified intelligence. Archer and the new Syrannite leader, T'Pau, delivered an ancient artifact, the Kir'Shara, to the High Command, initiating a reformation of Vulcan policy and philosophy, not only allowing Humanity to finally stand on its own but creating a new, trustworthy and more supportive Vulcan government, paving the way for the planet's eventual participation in the founding of the Federation. ()
===Babel Crisis===
By late 2154, the Romulan Star Empire perceived the developing partnership between Vulcan, Earth, and its neighbors as a threat. The Romulans' attempts to destabilize the region led to the Babel Crisis. Two Romulan drone ships camouflaged themselves to impersonate various other vessels, spreading distrust and hostility among local powers around Earth and Vulcan. However, Archer made alliances with the Andorians, Tellarites, and Vulcans to find and destroy the drone ships, thereby altering the result of this Romulan mission to the exact opposite of what it was intended to achieve. ()
===The idea of a Coalition of Planets===
With the averted escalation of the Babel Crisis, Earth and many other worlds realized the value of their joint work and were convening a conference in 2155 to discuss the formation of a Coalition of Planets. Yet this was opposed by a xenophobic isolationist group called Terra Prime under John Frederick Paxton, attempting to destroy the Coalition and convince all races that they could never live together. However, Enterprise was able to foil their plan to destroy Starfleet Command and Paxton was detained. As all the races were about to abandon the idea of the Coalition, Archer was able to make a passionate speech to all members in which he forwarded the notion that, as explorers, they should explore the galaxy together. ()
===Earth-Romulan War===
Several governments represented at the conference became welded together in 2156, when the conflict with the Romulan Star Empire escalated into the Earth-Romulan War. A humiliating defeat of the Romulans by an alliance of Earth, Vulcan, Andorian, and Tellarite forces at the Battle of Cheron in 2160 effectively ended the war and led to the establishment of the Romulan Neutral Zone between the two power blocs. (; ; )
===Foundation and early development===
In 2161, the year after the Earth-Romulan War was decided, the old war allies Earth, Vulcan, Andoria, and Tellar founded the United Federation of Planets by signing a treaty in San Francisco on Earth. The day of the official founding was later celebrated as Federation Day. Additionally, a new Federation Starfleet was officially established with a charter "to boldly go where no man has gone before." Starfleet Academy was established shortly after. (; ; ; )
Over the coming decades, vessels like the Archon, Franklin, Horizon, Essex, and the unmanned Quadros-1 probe explored space and expanded the young Federation's sphere of influence. Moreover, the was an important ship design within the fledgling Federation Starfleet until its retirement in 2196. The concept of starbases as logistical hubs for Starfleet's exploratory and defensive tasks also took hold very quickly. Plans to scout potential sites for starbases had already been underway in 2154 and by 2167, Starbase 12 was in operation. (; ; ; ; )
Jonathan Archer's role in these early years was an important one, too, as he became Federation Ambassador to Andoria in 2169 and served as Federation Councillor in 2175. He was eventually elected Federation President in 2184, stepping down eight years later in 2192 at age 80. ()
In the late 22nd century, the New World Economy took shape on Earth. Material needs and money became obsolete and to improve oneself became the challenge and driving force for most Humans. However, the Federation and its citizens continued to use monetary equivalents like Federation credits and latinum, both internally and externally. (; ; ; ; )
== 23rd century ==
===Constant expansion and setbacks===
The Federation's strive for discovery remained unbroken as exemplified by months-long sleeper ship missions to deep-space destinations, which were being conducted as late as 2210. With such strife as well as steady scientific progress, like the invention of the duotronic computer in 2243 and the commissioning of new powerful exploration vessels of the , like the in 2245, the Federation continued its constant expansion throughout the first half of the 23rd century. By 2267, the Federation was described as being "on a thousand planets and spreading out." (; ; )
In contrast to that, one of the worst crimes in Federation history occurred in 2246, when half of the 8,000 colonists on Tarsus IV were put to death at the orders of Governor Kodos during a food crisis inflicted by an exotic fungus. Incidents such as Kodos' genocide were not isolated, as the vastness of space made it difficult for the Federation to control corruption within their ranks. The crew of the Enterprise uncovered experimentation and torture at the Tantalus Penal Colony and violations of the Prime Directive committed on Ekos and Omega IV. ()
The Federation's constant expansion also meant inevitable tensions with neighboring spacefaring races. 
Intermittent encounters with the Gorn began in the 2230s or 2240s, including attacks on the and Finibus III, but never amounted to an official first contact due to the Gorn's habit of not leaving any survivors of warm-blooded species, who they considered their natural prey. () By 2259, tensions between the Gorn Hegemony and the Federation climaxed as the former deployed a ship near Galdonterre, causing fears of open war but also motivating the Federation to develop improved technology to combat the Gorn and enact the Gorn protocols as guidelines for a potential future conflict. Later that year, the Gorn attacked Parnassus Beta just outside of Federation space and transmitted a new demarcation line that would essentially annex the planet. () By 2267, no open war existed with the Gorn although the latter destroyed the Federation colony on Cestus III as a preemptive strike to annex the planet, which the Hegemony considered dangerously close to their territory. After a brief intervention by the Metrons, further hostilities were averted and Cestus III would remain a Federation planet in the long-term. (; )
An inadvertent trespass into Tholian territory in 2268 led to initial hostilities, but an escalation could be prevented. ()
At some point between the 23rd century and The Burn, Kaminar joined the Federation. ()
===Uneasy Federation-Romulan relations===
In 2266, the Romulan Star Empire emerged from seclusion to test the strength of its old enemy, the Federation. The Romulan Praetor ordered his finest flagship, a Bird-of-Prey that was equipped with a cloak as well as a powerful new plasma torpedo system and was under the leadership of an experienced commander, to violate the Romulan Neutral Zone and attack the Federation's observation outposts that lined the border in Sector Z-6. Finally, the marauding Romulan vessel was intercepted and defeated by the USS Enterprise before success could be reported, thereby marking the first confirmed visual observation of the Romulans' Vulcan-like appearance and proving the Federation's strength. ()
After this, the Romulans vigorously patrolled their side of the Neutral Zone and further encounters with trespassing Starfleet vessels were countered by the Star Empire by simply outnumbering their opponent. In 2268, despite this fact, the Enterprise managed to steal a cloaking device from a patrolling Romulan cruiser in order to assess the threat it posed to the Federation. ()
Despite these hostile encounters, the Federation managed to maintain a certain level of diplomatic interaction with the Romulans. In 2267, the Federation, the Romulan Star Empire, and the Klingon Empire jointly established a colony on Nimbus III, declaring it the "planet of galactic peace". The project however, quickly became an embarrassing failure for all three governments, although regular meetings between representatives did take place there for at least the next twenty years. The following year, the Polaric Test Ban Treaty was signed, banning research into polaric ion energy. (; )
The alternate reality diverged in 2233 following the incursion of the Narada from 2387 of the prime reality. The 's encounter with this formidable ship prematurely exposed the Romulans' appearance to the Federation, whose officers became aware of their history with the Vulcans and trained to become fluent in all three of their dialects by 2258. The Narada resurfaced that year with red matter seized from the which was used to destroy , but the crew were stopped from destroying the rest of the Federation. As was informed the Narada was not affiliated with the Empire, the attacks did not raise tensions between the Federation and the contemporary Romulans. ()
===Federation-Klingon wars and the way to peace===
:See also: Federation-Klingon Cold War, Federation-Klingon War (2256-57) and Federation-Klingon War (2267)
The most notable conflict in the 23rd century, however, was with the Klingon Empire, as the Federation was quickly expanding, and its territory began to approach the Empire's borders. Although tensions had existed between the Klingons and the Federation since the latter's founding, a tense cold war developed in 2223. While communication between both sides since the mid-22nd century was so rare that barely any Federation citizens have ever seen a Klingon, territorial disputes arose, e.g., over the Archanis sector. By the 2230s, an arms race took place that included Klingon research into time travel to which Section 31, a clandestine intelligence agency dating back to the original chartering of Starfleet, responded with its own time travel project. However, the project got halted after a critical component was thought lost due to a Klingon raid on a Section 31 research group on Doctari Alpha in 2236. This raid, as well as the inconclusive Battle of Donatu V in 2245, remained violent exceptions, however, as both sides refrained from committing to open warfare for the time being. (; ; ; )
Following Vulcan's destruction in the year 2258 of the alternate reality, began seeking ways to better defend the Federation, particularly against the Klingon Empire with which he believed war was inevitable. After finding the , he forcibly recruited , but Khan turned on him a year later and fled to Qo'noS. The crew of the came to apprehend him, but their confrontation with the Klingons there did nothing to improve Federation-Klingon relations. ()
In 2256, a brief but fierce was provoked by the actions of T'Kuvma, a Klingon noble who sought to reunite the disparate Klingon Houses by portraying the Federation as a mortal, encroaching enemy. T'Kuvma was martyred at the opening battle, the escalation of which was also made possible by the aggressive posture of Starfleet Commander Michael Burnham. The war concluded in 2257, when Starfleet desperately resorted to a direct assault on Qo'noS after it had lost tens of thousands of lifes, one third of its ships, and 20% of Federation territory, including Starbase 1, were under Klingon control. Without official orders, the planted a hydro bomb on the Klingon homeworld, whose detonator Burnham handed to L'Rell, an early follower of T'Kuvma, who used it to seize power over the Empire, end the war, and continue her former mentor's work of uniting the disparate Great Houses. Commander Burnham was subsequently exonerated for her failings at the beginning of the war and honored for her actions during its course. ()
In the months after the war that had cost one third of its ships, the number of active vessels maintained by the Federation Starfleet was about 7,000. Starfleet's Section 31 also intervened in Klingon politics to stabilize L'Rell's chancellorship, thereby preventing renewed Klingon hostilities. ()
In 2267, ongoing negotiations between the two sides were in danger of breaking down, and renewed open warfare was becoming an unwelcome likelihood. After the Federation refused the demands of the Empire to withdraw from all disputed regions along their mutual border, the Klingons launched an immediate offensive, seizing several planets including the strategically important Organia. Not willing to accept the bloodshed, the powerful incorporeal inhabitants of Organia brought about an abrupt end to by rendering the weapons of both sides nonfunctional and with the chairman of the Organian Council of Elders appearing to both the Federation Council and the Klingon High Council announcing the unilateral imposition of the Treaty of Organia. Establishing ground rules for further interaction between the two powers, the treaty helped to regulate disputes like that over Sherman's Planet some months after its signing. Besides, the aforementioned founding of the Nimbus III colony by the Federation, the Klingon Empire and the Romulan Star Empire took place in the same year. In addition to the failure of Nimbus III, however, a number of skirmishes and proxy wars continued to occur between the Federation and the Klingons over the next decade, including encounters at Capella IV, Neural, the Tellun system, and Beta XII-A. In 2285, further distrust arose when the Empire lost a ship which, by itself, became responsible for the destruction of two Starfleet vessels during its attempt to acquire a new Federation technology called the Genesis Device. (, ; ; ; )
With further meetings remaining without substantial results, like that at Korvat colony in 2289, the tense relationship with the Klingons stagnated. The situation abruptly changed in 2293, after the disastrous explosion of the Klingon moon Praxis caused severe economic problems for the Klingon Empire. The Klingons quickly approached the Federation, seeking a full peace treaty, leading to the Khitomer Conference and the Khitomer Accords in the very same year. In the face of this fundamental shift of power, the Romulans attempted diplomatic subterfuge through Ambassador Nanclus' role in the Khitomer conspiracy, albeit without success. (; ) It would become a defining Romulan motive of the coming decades to re-shift the balance of power by perturbing the peace brought by the Khitomer Accords. (; )
===Inexplicable threats===
Aside from these conflicts, the Federation faced more serious menaces during the second half of the 23rd century from genuinely alien threats. The Enterprise discovered sites of mass destruction and death caused by the probe Nomad, a gigantic space amoeba, and a weapon of destruction dubbed the planet killer, and put a stop to them. The Enterprise also faced off against the internal threat of the M-5 multitronic unit, which had turned on its creators. ()
Earth, the capital world, was nearly devastated on two occasions. The first occurred in the 2270s, when a massive machine lifeform called V'ger threatened to destroy all biological life on Earth, which it saw as a planetary infestation. Fortunately, the attack was narrowly averted by the USS Enterprise, which was able to reprogram V'ger. In 2286, an alien probe of unknown origin wreaked ecological havoc while trying to contact an extinct species of Humpback whale by transmitting massive amounts of energy into Earth's oceans. Again, the crew of the late Enterprise was able to rescue a pair of these whales from the past, which then, after being released to the Pacific Ocean of the year 2286, replied to the probe. (; )
== 24th century ==
=== Federation-Klingon détente, minor conflicts, and parasite infiltration ===
In 2311, a terrible confrontation between the Federation and the Romulan Star Empire, costing thousands of lives, occurred. This so-called Tomed Incident led to the signing of the Treaty of Algeron, which redefined the Romulan Neutral Zone and additionally banned Federation research into developing a cloaking device as well as use of any such device. It also was the last official contact between the Federation and the Romulans for the next fifty-three years. Still, the Federation maintained a number of outposts along the Romulan Neutral Zone and, in one instance, dispatched two starships to an outpost which had detected seven Romulan battle cruisers nearby. (; 
During the first half of the 24th century, the peace brought by the Khitomer Accords became somewhat rocky again and, by the 2340s, another war seemed to be on the horizon. However, the courageous sacrifice by the crew of the , who gave their lives in defense of a Klingon outpost under attack by the Romulans at the Battle of Narendra III in 2344, changed the setting. Being regarded as an honorable act, the incident enormously improved the Federation's image with the Klingon Empire. Although relations between the Klingon Empire and the Federation were still described as "not too cordial" around 2349, the Treaty of Alliance was signed by 2353, establishing a firm alliance between both powers. (; )
In the 2340s, 2350s, and 2360s, the Federation had to face several threats by various opposing parties.
The Federation-Cardassian War was one of the earliest and most severe of these conflicts. The war raged in a series of conflicts of various sizes, as the two powers struggled to protect their individual interests, with a major incident being the Setlik III massacre in 2347. The conflict was finally settled with the Jankata Accord and the Federation-Cardassian Treaty of 2370, creating a Demilitarized Zone between the two powers. This treaty, however, also changed the Cardassian border, placing some previous Federation worlds under Cardassian jurisdiction. Although the Cardassians agreed to allow Federation colonists to remain on some of these planets such as Dorvan V, resistance soon formed among the settlers. They quickly organized themselves into the militant Maquis, which continuously conducted terror attacks against both the Cardassian Union and the Federation almost until the outbreak of the Dominion War. (; )
Another incident occurred in 2353, when the Federation was in a conflict with the Tholians, who attacked a starbase resulting in the death of the entire base crew except for one one survivor. ()
In the late 2350s, the Galen border conflict was another series of skirmishes between the Federation and the Talarian government, fought over a three-year period. Although technologically inferior to the Federation, the Talarians compensated by a willingness to fight to the death and the employment of unconventional guerrilla tactics. The conflict took place over several border planets, including Castal I and Galen IV, which was overrun and destroyed by Talarian forces in 2357. Eventually, a peace agreement was signed between the two powers, which included the return of all prisoners of war. ()
During the early 2360s, the Federation was embroiled in a war with the Tzenkethi. ()
In 2364, the Federation faced a serious menace, when alien parasitic beings tried to infiltrate Starfleet Command. After the parasites managed to acquire high-ranking Starfleet admirals as hosts, they started to pave the way for an invasion of the Federation by subtly ordering the replacement of the command staffs of numerous outposts and colonies. The new staffs consisted of persons who had been in recent physical contact with Starfleet Command and thus were likely also infected. Admirals Gregory Quinn and Norah Satie proved instrumental in uncovering the alien plot and, with help from the crew of the , a cure against the parasitic infestation was found. However, although the parasite's mother was successfully destroyed, it managed to transmit a homing message before its death. ()
=== The Borg threat ===
The worst threat to the Federation came, however, when it made first contact with the Borg in 2365. It was on that occasion that it was discovered that the Borg were responsible for the mysterious destruction of several Federation and Romulan outposts on the edge of the Neutral Zone a year earlier. The Borg were an advanced race of hybrid cybernetic and biological beings who possessed a level of military technology far beyond that of anything known to the Federation. One year later, at the Battle of Wolf 359, the Federation's confidence came crashing down when a single Borg cube effortlessly sliced through an armada of forty starships. Although the Borg invasion was ultimately defeated, the effect on Federation morale was incalculable. After Wolf 359, Starfleet started to put more effort into defensive technology, which became apparent in new ship classes like the , , and , which were more combat-focused than the traditional research vessels that Starfleet employed. The availability of these new ships ultimately proved to be pivotal in the Dominion War. (; ; )
Another skirmish with the Borg took place in 2373, when another Borg cube attacked Earth. After Deep Space 5 reported the destruction of the Federation colony on Ivor Prime by the Borg, the first battle took place in the Typhon sector. Since the Federation fleet, under the command of Admiral , was not able to stop the Borg, the final battle was fought in Sector 001, in Earth's orbit, where the cube was eventually destroyed. Shortly before its destruction, however, the cube launched a sphere with a queen aboard, which subsequently traveled to the year 2063 in order to prevent first contact and assimilate Earth. The was able to follow the sphere, kill the queen, and assured that history transpired as it should. (, )
=== Destabilization of the Alpha Quadrant ===
:See also: Dominion cold war
In 2370, between the two attacks of the Borg, the Federation came in contact with the Dominion, a hegemonic major power from the Gamma Quadrant led by the Founders and first encountered through the Bajoran wormhole. ()
Ultimately, the Dominion planned to bring its version of "order" to the, in their view, "chaotic" Alpha Quadrant, starting a cold war covering a three year period of Dominion-orchestrated successes at destabilizing the Alpha and Beta Quadrants.
A primary tool of manipulation for the Dominion was the replacement of key persons by Founder-Changelings. In that manner, the neutralization of the Romulan Tal Shiar and the Cardassian Obsidian Order was accomplished by luring their fleets into a trap at the Battle of the Omarion Nebula in 2371. Secretly hoping for their success at destroying the , Starfleet chose not to interfere with the Romulan-Cardassian attack plans. () Also in 2371, a Founder, who had replaced Federation Ambassador Krajensky, almost managed to instigate a new conflict between the Federation and the Tzenkethi. (. In 2372, a Changeling bombed the Antwerp Conference between the Federation and the Romulans on Earth, giving rise to massive paranoia within the Federation government as well as Starfleet Headquarters. Since Federation President Jaresh-Inyo initially blocked any extended security measures to preserve the "Paradise Earth", Starfleet Admiral Leyton tried to take advantage of the situation by staging a coup d'état. However, after it was learned that only four Changelings were currently operating on Earth, the coup failed, showing to the Federation the urgent need to resolve its inner conflicts so it could stand its ground against the Dominion. ()
Besides these manipulations, the Dominion was able to trigger a war between the Klingons and the Cardassians in early 2372 (see Klingon-Cardassian War). Being the first major strain on its alliance with the Klingon Empire, the Federation condemned this war, which led Klingon Chancellor Gowron to withdraw from the Khitomer Accords. In early 2373, the Dominion managed to deteriorate Klingon-Federation relations further into open war, ultimately breaking out about their old dispute over the Archanis sector, with battles fought on Archanis IV and Ganalda IV amongst others. (see: Federation-Klingon War (2372-73)). When it was discovered that Klingon warmonger General had actually been replaced by a Founder too, the Federation-Klingon war was ended and a cease fire signed. However, relations remained strained, with the Klingons at least once breaking the ceasefire and invading Ajilon Prime. ()
With the Dominion gaining a physical foothold in the Alpha Quadrant through the joining of the Cardassian Union, several months later in mid-2373, the Khitomer Accords were put back into effect, since war seemed inevitable and only a Federation-Klingon alliance could hope to stand against the forces of the Dominion. ()
=== The Dominion War ===
:See also: Dominion War
====Outbreak of the War and retreat of the Federation====
After settling the hostilities with the Klingon Empire and facing considerable losses from the recent Borg attack, the Federation had depleted its means of preventing an all-out conflict with the Dominion. The ensuing Dominion War was the bloodiest conflict that the Federation had ever been drawn into, up until then, and caused major changes on the political stage of the Alpha and Beta Quadrants.
The fortification of the Cardassian Union, combined with the securing of non-aggression treaties with notable powers such as the Miradorn, Tholians, Bajorans, and, most importantly, with the Romulans, made Dominion intentions clear. The Federation was forced to act, but could not present the aggressive stance of something so bold as a preemptive strike. Instead, the decision was made to mine the Bajoran wormhole, to prevent further Dominion reinforcements from arriving. ()
The maneuver was sure to provoke the Dominion into attack and this end was achieved. Despite a seemingly successful negotiation between Weyoun and Captain Sisko (which, if put into action, would have limited Dominion vessels from the Gamma Quadrant to medical and economic supplies, to help the Cardassian Union rebuild), the Dominion prepared to attack Deep Space 9. Although the Dominion forces arrived too late to prevent the minefield from being successfully deployed and activated, thus preventing reinforcements from arriving in the Alpha Quadrant, the Dominion continued its assault on Deep Space 9, eventually forcing all Federation forces aboard to evacuate in late 2373, and took over the station immediately after its abandonment by the Federation.
Countering the attack on Deep Space 9, the Federation-Klingon alliance dispatched a successful task force to attack the Dominion shipyards at Torros III, setting back Dominion ship production for months. ()
During the first few months of 2374, the Dominion was leading an extremely successful campaign against the allies, forcing them to retreat on nearly every front. In an attempt to stop the Dominion's advance into their territory, the Federation dispatched its Seventh Fleet to the Tyra system; a force composed of 112 vessels of which a mere fourteen ships were able to make it back to their lines - a disastrous defeat for the Federation. ().
====Counter-offensive, stalemate, and the Ba'ku-incident====
By the second quarter of that year, it was revealed to the Federation that the Dominion was close to deactivating the minefield blocking the wormhole, and Captain Sisko told Starfleet that the station's recapture had to be seen as the top priority of the war. Admiral Cobum objected to the plan, fearing that too many ships would be diverted away from Earth, allowing the Dominion to attack it, but Sisko was able to convince him otherwise. With only three days before the minefield could be deactivated, however, the Federation was forced to launch what ships they had been able to gather to attack Deep Space 9 and start Operation Return. A Federation fleet of over six hundred vessels, eventually aided by Klingon forces, enabled the to break through the Dominion's lines, consisting of 1,254 ships, and reach Deep Space 9, where Captain Sisko was able to convince the Prophets to entirely wipe out the Dominion reinforcements while they were traveling through the wormhole. With no reinforcements on their way, and the fleet battle in favor of the Federation-Klingon forces, the Dominion was forced to withdraw from the station. ()
Despite their successful retaking of Deep Space 9, the Dominion was able to occupy Betazed during the Battle of Betazed in late 2374, although the Federation's Tenth Fleet had been assigned to defend the planet but was caught out of position on a training exercise. With the capture of this system, the Dominion was in a position to invade Vulcan, Andor, Tellar, and Alpha Centauri. Furthermore, the Federation was suffering a manpower shortage after sustaining massive casualties up to this point, and many of their shipyards were still being rebuilt. The Dominion's shipyards, on the other hand, were producing at 100% capacity and legions of Jem'Hadar were being bred at an incredible rate. In order to turn the tide by bringing the Romulan Star Empire into the war, Captain Sisko undertook a successful ploy and the Romulans joined the Federation Alliance. ()
With Romulan reinforcement, the Federation Alliance somewhat regained the initiative, quickly recapturing important Federation worlds like Benzar, and in late 2374 for the first time managed to take Dominion territory in the victorious First Battle of Chin'toka. ( The first half of 2375 was spent with neither side offering a firm push forward into the other. One very important event that changed the shape of the war was occurring behind the front lines: a debilitating disease was attacking the Founders. It was later claimed that Section 31 had a hand in the infection. The Founders' abilities as leaders were being compromised just as their military was taking severe punishment from the emboldened alliance. ()
Nevertheless, the war and the attacks of the Borg had already caused enormous losses. Seeking new strength and momentum, the Federation Council's policy changed and the admission of new members was accelerated, like with the Evora, whose homeworld was declared a protectorate the year after they achieved warp drive. First and foremost, however, the Council's ethic decisions became more questionable, even compromising the principles upon which the Federation had been founded. This posture led to the decision to allow the secret relocation of some six hundred Ba'ku in order to harness the life-prolonging metaphasic radiation of their planet's ring system. This, however, could only be accomplished by using technology from the dubious Son'a who were also collaborating with the Dominion. Eventually and thanks to the actions of the USS Enterprise-E and her crew, the relocation could be delayed and the Federation Council finally halted the plan to start a top-level investigation. (; )
====Raid on San Francisco, turning of the tide and victory====
Some months later, the tide of the Dominion War turned against the Federation Alliance again, as the Breen Confederacy entered the war on the Dominion's side. The Breen even staged an attack on Earth, dealing a heavy blow to Federation morale. Starfleet and Romulan vessels were annihilated by the Breen's energy dampening weapons, forcing the Klingons – whose ships could be modified to be immune to the weapon - to hold the front lines on their own, until a countermeasure could be found. To compensate, Martok had his fleet operate in small battle groups, remaining cloaked until they engaged the enemy, in an attempt to keep them off balance. ()
With the emergence of a Cardassian Rebellion movement, the Federation Alliance was able to capture a Jem'Hadar attack ship fitted with one of the Breen's energy dampening weapons, so a counter measure was able to be produced for both Federation and Romulan ships, thus returning the tactical advantage into the Allies' favor. ()
Although the Cardassian Rebellion was crushed soon afterwards, the Dominion made the decision to withdraw from Klingon, Federation, and Romulan territory and fortify essential Cardassian territories with a new defense perimeter behind which it could rearm and prepare for a new assault on the Alpha Quadrant. The Allied commanders determined that the best hope for success was an immediate invasion, before the Dominion was allowed to strengthen itself any further. A three-pronged attack into Cardassia was organized and authorized by Admiral William Ross, now-Chancellor Martok and Romulan General Velal. After the Alliance captured Cardassia Prime in the Battle of Cardassia, the war was officially ended with the signing of the Treaty of Bajor and all Dominion forces returned to the Gamma Quadrant, with the exception of the head Founder who was to stand trial for war crimes. Eight hundred million Cardassian civilians were dead; the entire Cardassian Union had totally collapsed. The Alpha Quadrant had lost a major power and the effects on galactic politics continued to be seen for many years to come. ()
===The Pathfinder Project and the return of the USS Voyager===
During the late 2370s, the Federation was able to achieve a moral success as well as a breakthrough in extreme long-range communication, after the had gone missing in the Badlands in 2371. After it was discovered that the ship had actually been transported to the Delta Quadrant, the Starfleet Communications Research Center launched the so-called Pathfinder Project, which was able to establish two way communication with Voyager in 2376. With its return to Earth in 2378, Voyager not only brought with it a tremendous amount of information on the previously unexplored Delta Quadrant, including an immense amount of tactical data on the Borg, but also destroyed one of only six Borg transwarp hubs, defining a strategic blow to their infrastructure. ()
=== Reman coup d'état and changing relations with Romulus ===
In 2379, one year after Voyagers return home, the Federation was confronted with a tempting peace offer by the Romulan Star Empire, which, however, turned out to be one of the gravest threats Earth had to face during this century. After an apparent Reman uprising in the Star Empire and the assassination of the Romulan Senate, the new Praetor, Shinzon, was making an appeal for peace with the Federation. After Starfleet sent their flagship, the USS Enterprise-E under Captain Jean-Luc Picard, to Romulus, Shinzon's actual plan to install the Romulan Empire as the major power in the Alpha and Beta Quadrants by kidnapping Picard and eradicating all life on Earth by the use of a thalaron radiation weapon became clear. Fortunately, with the help of a few disillusioned Romulan ships, the Enterprise was able to destroy Shinzon's flagship, thwarting his plans and saving Earth from a devastating attack.
After the death of Shinzon, the initial approaches between the Federation and the Star Empire were continued and a new task force led by the was dispatched to the Romulan Neutral Zone in order to begin talks with the Romulans. ()
In the 2380s, the Federation was asked for help in evacuating Romulus due to an impending supernova. Now-Admiral Picard lobbied on the Romulans' behalf and the Federation began constructing a rescue armada of ten-thousand warp-capable ferries. However, the move was very controversial, and fourteen species within the Federation threatened to pull out if the Romulans were not cut loose. After rogue synths attacked Mars in 2385, which cost over 90,000 lives and destroyed the Utopia Planitia Fleet Yards along with the rescue armada, the Federation not only banned all synthetic life but also withdrew its offer of assistance to the Romulans. Whilst unknown at the time, the attack had actually been orchestrated by the Zhat Vash, an ancient and secret cabal operating under the guise of the Tal Shiar, who wanted to push the Federation towards anti-synth legislation. ()
In 2387, despite a desperate last-minute attempt by Ambassador Spock to stop the supernova with red matter, the supernova destroyed Romulus. The Romulan miner Nero subsequently blamed the Federation for the disaster and the death of his family. He and Spock subsequently went missing when their ships disappeared in the singularity created by the red matter. ()
=== Ban of artificial lifeforms ===
Because it could not be determined how or why the synths went rogue that led to the attack on Mars, the Federation Council placed a ban on the creation of synthetic lifeforms. Since then, there were multiple cases against artificial lifeforms, namely the incident of the , happened in 2389, when Beautiful Flower and Jana were killed. It was not until 2399 when the ban on synthetics was lifted upon the discovery that the Zhat Vash was behind the attack on Mars. ()
== 25th century and beyond ==
In 2401, a reformed Borg Collective led by a partially assimilated Agnes Jurati, requested provisional membership in the Federation in order to monitor a mysterious transwarp conduit whose creators were believed by the Borg to constitute a threat. ()
Later, in the same year, during the Frontier Day celebration, Earth was attacked by a Starfleet whose ships' youngest crewmembers had been assimilated by the Borg through genetic reprogramming implanted into their transporter systems by rogue Changeling infiltrators. Shortly thereafter, a Borg cube was discovered in the atmosphere of Jupiter transmitting what little remained of the Borg collective's signal. Although Earth Spacedock was destroyed, and Earth's planetary shields fell, the cube was subsequently destroyed, freeing the ship's crews before they could begin Orbital bombardment. (); ()
By 2402, Earth's defenses had been rebuilt and a brand-new technological solution had been implemented to screen for Changeling infiltrators. ()
At some point in the 25th century, Barzan II joined the Federation. ()
By the 26th century, races such as the Klingons, Ithenites, and Xindi had joined the Federation. In an alternate version of the 2550s, the Federation won the Battle of Procyon V against the Sphere-Builders and proved instrumental in reversing their invasion of the Milky Way Galaxy. ()
===Time travel and the Temporal Cold War===
By the 26th century, time travel technology became an established factor in the Federation, enabling it to explore historical events, in part by the use of timeships. A Temporal Integrity Commission was soon formed as well as Temporal Accords, dedicated to prevent any temporal incursions, intentional or unintentional, from occurring or the timeline from collapsing and ensuring that the exploration of time could be performed without interferences. However, from various sides, there rose massive opposition to these restrictions to time travel and the Federation was soon drawn into a Temporal Cold War that spread across history, involving numerous factions, some of whom even tried to alter history in order to prevent the Federation from forming. (; ; )
In the 29th century, Starfleet Captain Braxton located the starship Voyager in the Delta Quadrant of the year 2373, claiming that, in his century, it had been unwillingly responsible for the destruction of the Federation's entire capital system around Sol by a temporal explosion. Trying to restore the timeline, Braxton tried to destroy Voyager, which was able to disrupt Braxton's ship, however, pulling both ships into different decades of the 20th century. There, temporal contamination by the advanced technology of Braxton's ship turned out to be the very reason for the temporal explosion in the first place. Fortunately, Voyagers crew was able to prevent this contamination, so an alternate version of Braxton who never experienced these events was able to return Voyager to the Delta Quadrant of the 24th century, ending this temporal incursion. ()
In order to intentionally thwart the foundation of the Federation, the historical events surrounding Captain Jonathan Archer of the Enterprise posed a tempting target. A temporal agent from the 31st century posing as crewman on the Enterprise assisted Captain Archer and his crew numerous times in order to take their roles in history and maintain the timeline. In 2152, however, Daniels inadvertently averted the Federation from ever coming into being by taking Archer some nine hundred years into the future. Thanks to his crew and a Suliban's misunderstanding, he returned to his own time period, resetting the timeline. ()
Another instance that nearly prevented the Federation from being founded was when a weapon created by the Xindi attacked Earth, killing seven million people. A race of transdimensional aliens, called Sphere-Builders, were defeated by the Federation in the 26th century so they deceived the Xindi into thinking Earth would attack them in the future, convincing them that they should preemptively attack Earth and annihilate Humanity, thereby eradicating the future Federation. With more help from Daniels, Archer and his crew were ultimately able to destroy the weapon as well as the sphere network, ending the Sphere-Builders influence in normal space. ()
Enterprise and its crew were not yet finished with the Cold War, however, as they were subsequently brought to an alternate 1944, where a dangerous time traveling faction known as the Na'kuhl from the 29th century were assisting Nazi Germany in conquering America, thereby altering history and again preventing the formation of the Federation some two hundred years later. Enterprise destroyed the temporal conduit of the Na'kuhl which, in turn, prevented the crew's return to their century. As a result, many temporal incursions were erased; the Temporal Cold War was coming to an end and the timeline ultimately reset itself, paving the way for the historical events leading to the birth of the Federation. (, et al.)
====32nd century====
By the 32nd century the United Federation of Planets had mostly dissolved after The Burn sometime during the 31st century. The Federation and Starfleet had relocated their headquarters to a space station with a distortion field to mask their location. ()
By 3189, approximately 120 years after the galaxy wide event known as "The Burn", which decimated warp faring civilization, the Federation was reduced to only 38 formal member worlds, from a high of 350. () By 3190 this had increased to 58, () then 59 after Earth rejoined the Federation. (DIS: )
Following the hijacking of the , the Federation was able to start rebuilding itself when rejoined. Other worlds, such as Ni'Var, followed suit, returning to the Federation in late-3190. ()

=== Background information ===
Based on Deanna Troi's line in "this alliance will give birth to the Federation", the signing ceremony shown could well be the signing of the Coalition of Planets' charter or for some other precursory alliance to the actual Federation. While that is a legitimate interpretation, the line itself is ambiguous and could easily refer to the present state of the Federation as its own nation rather than an alliance. Further, exactly the same scene was observed in , wherein it was explicitly identified as the signing of the Federation Charter.
The clipping It's Federation Day!, from the Picard family album created for , gives additional details about the founding of the Federation, including the names of the signatories, the exact date (October 11) and that the Human-settled Alpha Centauri system was the fifth founding member. However, that particular item did not appear on-screen. 
Various other non-canon sources have given the exact date of the founding as May 8 (Last Full Measure), June 30 (Star Trek: Star Charts), and August 12 (Star Trek Online).
