6th gigennium BCE

  • c.5 to 6 billion ya: Complex multicellular life first develops in the Milky Way. (TNG Novel: The Buried Age)

5th gigennium BCE

  • c.4.5 billion ya: The first humanoids evolve in the Milky Way, and spread throughout its full extent. Finding themselves to be the first such race by all account, they seed numerous worlds across the galaxy with the building blocks for eventual re-emergence of humanoid life following their own eventual extinction, as well as encoding a message in said building blocks to be discovered upon the eventual cooperation of the resulting species. This message is discovered (likely one of many times) in 2369 by combined efforts of the Federation, the Klingon Empire, the Romulan Star Empire, and the Cardassian Union. (TNG: "The Chase")

2nd gigennium BCE

  • c.2 billion ya: The Imotru reach sentience on Tagus III. By the 23rd century, they are noted as the oldest sentient race in the Milky Way of which there was firm evidence, something only overturned in 2369 upon the discovery of the message of the first humanoids. (TNG Novel: Q-Space, The Buried Age; TNG: "Qpid")
  • Overall progression in the galaxy throughout this gigennium is marked by the ascension of individual intelligent species into galaxy-wide domination, followed by brutal war as new species emerge, continuing until c.600,000,000 ya (TNG Novel: The Buried Age)

1st gigennium BCE

  • c.600 million ya: The Manraloth form the first true interstellar alliance in the galaxy, ushering in nearly 350 million years of peace following millions of years of horrid warfare (TNG Novel: The Buried Age)
  • c.252 million ya: The Manraloth disaster leads to the extinction of all sentient life in the galaxy, as well as the disruption or extinction of lower life forms on multiple worlds. Mass extinction on multiple worlds, including Earth and Alpha Centauri VII, could be partially credited to the fallout of this event. (TNG Novel: The Buried Age)

1st decamegennium BCE

c.5-10 million ya

  • The Organians transition away from the physical plane, becoming beings of energy. (TOS: "Errand of Mercy"; TNG Novel: The Buried Age)

1st megennium BCE

c.600,000 ya

c.500,000 ya

  • The Arret Empire collapses, initiating the Sargonian diaspora. Survivors of the Empire end up becoming the ancestor species of numerous humanoid and vulcanoid species in the Alpha and Beta Quadrant in the years following. (TOS: "Return to Tomorrow"; TNG Novel: The Buried Age)

c.250,000 ya

  • The Talosian civilization nearly destroys itself in nuclear war, rendering the surface of Talos IV uninhabitable. The survivors train their mental abilities to allow for the manifestation of perfectly real illusions, so as to buoy the limited experiences available underground. (TOS: "The Cage", "The Menagerie"; TNG Novel: The Buried Age)

214,000 BCE

  • The Mro civilization dominates much of the Alpha Quadrant, oppressing and exterminating all challengers to their rule. (TNG Novel: The Buried Age; DTI Novel: The Collectors)

212,000 BCE

  • The Mro civilization collapses once, with no other foes to target, the Mro were forced to turn on one another to satisfy their aggressive urges. (DTI Novel: The Collectors)

c.200,000 ya

  • The Iconian civilization rises, granted the technology to form gateways of instantaneous transit across space and, for some, time via a piece of Q technology. The civilization came to dominate much of the galaxy, until an attack from other civilizations neighboring their homeworld, fearing them as "Demons of Air and Darkness", led them to retreat inwards and withdraw from galactic society. (TNG Novel: The Buried Age; TNG: "Contagion"; VOY Short Story: "Into the Queue")

c.50,000 ya

  • The people of Cheron wipe themselves out in a massive war, biochemical agents ending all life on their world to the microscopic level. (TOS: "Let That Be Your Last Battlefield"; TNG Novel: The Buried Age)

28th millennium BCE

  • Bajoran culture in its modern incarnation first begins, as the religion of the Prophets as proselytized by the Bajora, originally one of many subcultures on the planet, spreads across the entirety of the world. The planet gains the name of Bajor at this time, after that subculture. (TNG Novel: The Buried Age; DS9 Short Story: "Horn and Ivory")

23rd millennium BCE

  • The ancestor species of Trill first joins with a symbiont. (DS9 Novel: Trill: Unjoined)
  • The city on which the Bajoran city of B'Hala will be built is abandoned. (DS9: "The Reckoning")

18th millennium BCE

  • The location of the Bajoran city of B'Hala is lost by this time. (DS9: "Rapture")

8th millennium BCE

  • Written Ferengi history begins. (DS9: "Little Green Men")
  • The Kalandan civilization reaches its height. (TOS: "That Which Survives"; TNG Novel: The Buried Age)
  • c.7500 BCE: The Fabrini launch Yonada as a means of preserving some portion of their culture upon the soon-approaching supernova of their home star. (TOS: "For the World is Hollow and I Have Touched the Sky"; TNG Novel: The Buried Age)
  • The Ky'rha civilization reaches its height. (TNG Novel: The Buried Age)

6th millennium BCE

  • A vast plague wipes out the Kalandan civilization, leaving only automated outposts as surviving indicators of their former presence. (TOS: "That Which Survives")

4th millennium BCE

  • The Furies hold a significant presence across local space — including some level of domination of early Human, Andorian, Vulcan, Klingon, and Ferengi cultures, serving as the source of a number of myths and legends. (Novel: "Invasion!" series)
    • Part of this domination may have included genetic experiments upon the natives of Qo'noS to transform them in their own image, including the development of their biological redundancies and the genetic abnormality later known as the JoH'a mu'qaD. Due to this, their place in Klingon mythology otherwise, and the similarities of both them and the victims of the JoH'a mu'qaD to the figure known as Fek'lhr, they may have been the source of the original myths of the Klingon gods as a whole, suggesting that legends of their banishment were distorted over the years to the modern story of the Klingons slaying their gods.

3rd millennium BCE

4th century

  • Those on Vulcan who "marched beneath the raptor's wings", the eventual precursors of the Romulans, depart the planet in the midst of the spread of Surak's philosophy. (ENT: "Awakening")
  • The death of Surak ushers in the Time of Awakening on Vulcan, as more and more Vulcans take to a philosophy of logic and emotional control over the decades and centuries to come. (ENT: "Awakening")

8th century

10th century



  • Jelna astronomer Lovar Dleba develops an accurate enough telescope to identify Zami cities on Rigel IV. (Tower of Babel Annotations)

12th century

  • The Confederacy of Vulcan is established when the planet is finally fully united under the philosophy of Surak. (Presumptive)



  • First contact between Jelna and Zami when Jelna astronauts land on Rigel IV. (Tower of Babel Annotations)

13th century


  • Jelna forcably resettle Kalar on Rigel VII over the course of decades, heavily straining Zami economies and labor. (Tower of Babel Annotations)

Late century

  • Crowded and unsanitary Kalar transport ship conditions lead to viral cross-propogation and mutation, leading to the development of Rigelian fever. The epidemic quickly spreads across both Rigel IV and Rigel V, leading to tens of millions of deaths. (ENT Novel: Tower of Babel; Tower of Babel annotations)

14th century

  • The Hur'q, a domineering and vicious alien species native to the Gamma Quadrant, invades Qo'noS as part of a long-term sweep across the Beta Quadrant, intending to subjugate the Klingons and plunder their homeworld of resources and treasures. While may artifacts are stolen, including the Sword of Kahless, the Klingons manage to repel the invasion, jumping from basic land transport directly to warp travel as a result of captured technology. (DS9: "Sword of Kahless"; TLE Novel: The Art of the Impossible)
    • Following the departure of the Hur'q, the Klingon hero Ch'gran uses captures Hur'q facilities to construct a fleet of seven vessels with which to conquer the heavens, to ensure the invasion could not be repeated. Departing exactly one year following their departure, the fleet is lost shortly after communicating the discovery of the first world to be taken by the burgeoning Klingon Empire, its fate unknown. (TLE Novel: The Art of the Impossible)
      • Wreckage in the Betreka Nebula discovered in the 2290s revealed that Ch'gran in fact planned to conquer worlds purely for his own benefit and use their resources to eventually conquer Qo'noS itself, his plans upended only by the mutiny of his subordinate captains, leading to the destruction of the fleet. This fact was suppressed by Chancellor K'mpec and Imperial Intelligence upon its discovery, so as to preserve the legend. (TLE Novel: The Art of the Impossible)
  • The outpost on Babel is constructed by peacemaking efforts from devastated Menthar and Promellia, hundreds of light years from the territory of either race in neutral territory, in a final attempt to forge a place to negotiate an end to the war before their extinction. Before the outpost can be completed, the surviving fleets of both civilizations met by happenstance at the Orelious system; every surviving ship is recalled to what would be the final battle, including those at Babel. While some survivors may have fled the battle to forge new societies elsewhere, Menthar and Promellia are ended. (ENT Novel: Tower of Babel; TNG: "Booby Trap")


  • Zami develop a ryetalyn-based cure for Rigelian fever, saving millions of lives. (Tower of Babel Annotations)

16th century

  • First contact between Chelons and Jelna. (Tower of Babel Annotations)



  • The Rigelian Trade Commission is founded, leading to the establishment of the United Worlds and Colonies of Rigel. Initially, the board consists of only Jelna and Zami, with token Chelon representation. (ENT Novel: Tower of Babel; Tower of Babel Annotations)

17th century

  • Rigel II terraformed and colonized (Tower of Babel Annotations)

18th century

  • Chelon rebellion against the Rigelian Trade Commission leads to improved and equalized representation for Rigel III. (Tower of Babel Annotations)
  • Babel is first used as a diplomatic meeting ground, as the site for the Ramatis Choral Debates, the event at which Ramatis first solidified its reputation as a home of great diplomats. (ENT Novel: Tower of Babel)


  • The Rigelian Trade Commission has essentially become a de facto interplanetary government for the planets of the Raij'hl system. (Tower of Babel Annotations)

19th century

Early century

  • The Confederacy of Vulcan becomes an interstellar power with the discovery of warp drive. (ENT: "The Forge")
    • As the Confederacy expands its sphere of influence, it serves as a mediating force preventing the various aggressive nations and criminal organizations in the core territories from impacting pre-warp civilizations within their reach, including Earth. As a result, extraterrestrial contact with Earth drops significantly from the late 19th century onwards.
  • The Cardassian Union is founded (DS9: "Defiant")


  • First contact (of a sort) occurs between Vulcans and the Romulan Star Empire, leading to the century-long Vulcan-Romulan War. (ENT Novel: To Brave the Storm, Uncertain Logic)
    • c.1905 described as "about midway" through the war by Uncertain Logic


  • The Antaran-Denobulan War ends. (ENT: "The Breach"; ENT Novel: Uncertain Logic)
    • By the end of the war, the Antaran death toll has reached 20 million. (ENT: "The Breach")
  • The Andorian Empire forms with the unification of Andor's warring clans by Thalisar the Last (DS9 Novel: Andor: Paradigm)
  • An illicit Skagaran slave trade begins, abducting Humans from Earth's North American continent for forced labor. This slave trade is quickly halted through the intervention of an interplanetary organization of anthropologists known as the Preservers. (TNG Novel: The Buried Age; Buried Age annotations)



20th century

Early 20th century

  • First contact between Vulcans and Andorians; though initially peaceful, what is seen as paternalistic oversight from the Vulcan emissaries leads to the Andorian Empire expelling them from the Kuy'va system. (ENT Novel: Uncertain Logic)



  • First interstellar contact for the Raij'hl system, when a Coridanite warp cruiser arrives in-system, opening trade. (Tower of Babel Annotations)


  • The Vulcan-Romulan War ends as Praetor Sartorix decides to instead infiltrate and redirect Vulcan society, so as to lead them to eventual reunification with Romulus (ENT Novel: Uncertain Logic)
    • The reduction of Romulan aggression coupled with the increasing militarization of the Vulcan High Command leads to tighter control over Nevasa-local space, drastically reducing the rate of alien infiltration on Earth as a side-effect.

Mid 20th century

  • The Andorian Empire becomes spacefaring beyond the confines of its home system, when advances in their theoretical sciences gained via inspection of Vulcan technology lead to the development of warp drive. (ENT Novel: Uncertain Logic)

Late 1960s

  • Dr. Sarina Kaur, a brilliant geneticist, founds the Chrysalis Project, a gathering of other leading geneticists, biochemists, and microbiologists in an attempt to breed superhumans through eugenics and genetic engineering techniques. Her plan (unbeknownst to most participating in the Project) consists of eventually wiping out baseline humanity through the targeted release of a genetically-modified strain of necrotizing fasciitis designed to be even more virulent, to clear the planet for her Chrysalis children (later known as Augments).



  • May 19: The Chrysalis Project is ended through the intervention of Gary Seven and Roberta Lincoln, but not before dozens of children have already been bred over the four years prior. These children are placed in homes around the world, and though not informed of their heritage, they eventually discover their true lineage.



  • The Great Khanate rises in the remote deserts of Chandigarh, India, Earth, led by the self-proclaimed Khan, Noonien Singh. Despite the efforts of India to suppress his rule, immense popular support prevents the Indian government from taking direct action. Still, little attention is given to him outside the country, seen as nothing but a trivial local warlord. Across the world, other powerful, charismatic, and somewhat unbalanced figures begin to draw followers to themselves in various nations, including Randall "Hawkeye" Morrison, leader of the Army of Eternal Vigilance, an anti-government militia based in Arizona; Chen Tiejun, founder of a separatist matriarchal colony off the coast of New Zealand; Elijah Amin, one of the most influential warlords in Somalia; Vasily Hunyadi, a highly-placed figure in the Yugoslavic civil wars; Alberto Gomez, leader of a Peruvian rebel army seeking the reformation of the Incan Empire as a Marxist state; and Brother Arcturus, founder of the suicide cult known as the Panspermic Church of First Contact. To the international community, these figures seem disconnected and unrelated, mere blips amidst the worldwide chaos of the late 20th century.



  • Following the failure of uniting his brethren in the name of world conquest, Khan Singh instead decides to seek war against them. Thus begin the Eugenics Wars, a series of shadow wars fought through third-parties and proxies via the manipulation of other brewing conflicts by the Chrysalis Augments to their own benefit.


  • The Eugenics Wars end following the revelation to the world’s nations of their existence. Most Augments are thought killed in the aftermath, though a number of partially-developed augmented embryos that survive the various bombing campaigns in a state of medical stasis are captured by the nations of the world, unsure what fate they deserve. Ultimately, these embryos are consigned to a number of secure cryonics stations dotting near-Earth space. Following the revelation of the Eugenics Wars and the chaos the Augments brewed across the world in their deigns for conquest, the nations of Earth ban genetic augmentation and genetic engineering of humankind.
  • The first DY-100, the first model of the DY series of sleeper ships, is launched, with many more to follow. It is later supplanted by the DY-500; both lead to Earth’s first wave of interplanetary exploration, though these ships are not likely to reach their destinations for decades, if not centuries.

21st century



  • Jan 01: The Millennium Gate, Earth’s first self-contained and self-sustaining biosphere, begins construction outside Portage Creek, Indiana in the United States, intended to serve as a model for the first Martian colony. When completed in 2012, it spans 3.2 kilometers wide, with a height of nearly one kilometer, totally covered in reflective solar panels that render it easily visible from orbit. (VOY: "11:59")


  • NASA launches the first true interstellar probe, the Nomad MK-15c. Designed by Dr. Jackson Roykirk, it was also Earth’s closest approximation of true AI to date, intended to function without contact from Earth or other vessels for prolonged periods in order to seek out and communicate with extraterrestrial lifeforms. Earth eventually loses contact with Nomad, as expected. (TOS: "The Changeling")


Late 2010s

  • Even as the technological developments of the human species seem to continue unceasingly, the nations of Earth fall into further chaos, possibly still suffering the aftermath of the international manipulations of the long-since defeated Augments. Civil unrest broils worldwide as a result of global economic and environmental turmoil and growing poverty and unemployment, concentrated especially in western Europe and the United States. The United Nations collapse under the weight of the growing global crises. (TNG: "Encounter at Farpoint")
  • In the United States, poverty had grown to such a degree that the Employment Act of 1946 was repealed, the Federal government abandoning any claim towards ensuring the employment and economic stability of its citizens. As an alternative, most major American cities instituted “Sanctuary Districts”; intended to be neighborhoods devoted specifically to providing homes to those without the means to obtain them otherwise, these districts soon degenerated into nothing more than massive outdoor debtors’ prisons. Similar measures were seen in other nations as well, with many governments choosing to hide their poverty-stricken citizens away rather than address the underlying issues responsible for their state. (DS9: "Past Tense")
  • To help stave off the growing economic troubles, the Eastern Coalition (ECON) is formed, an alliance of various Asian states largely dominated by the People’s Republic of China, but also including India, Pakistan, Iran, Kazakhstan, Vietnam, and Singapore as members. As a demonstration of dominance, the ECON’s space agency manages a successful manned return to the moon before any of the more dominant space agencies can accomplish such. (TLE Novel: "The Sundered"; TOS Novel: "The Rings of Time")


  • First contact occurs between the Vulcans and Klingons, leading to decades of war following. (ENT Novel: A Choice of Futures; DIS: "The Vulcan Hello"; TNG: "First Contact")


  • Due to the discovery of internally metered pulse drive technology (also known colloquially as "impulse drive"), allowing travel time to nearby planets to be cut from years to months, sleeper ships are slowly phased out of Earth production. Many DY series ships are still en route to their destinations, overtaken by newer vessels.



  • The first successful manned mission to another planet in the solar system is completed, with NASA astronauts Christopher, Fontana, and O’Herlihy arriving at Saturn in the UNSS Lewis & Clark in a mere three months thanks to recently-developed impulse drive technology. This mission is intended largely to recover face lost by the ECON’s moon launch, but also to analyze the recent odd deterioration of Saturn’s rings and increasing activity of its renown hexagonal polar storm. (TOS: "Tomorrow is Yesterday"; TOS Novel: "The Rings of Time")


  • September 1-7: The Bell Riots in San Francisco's Sanctuary District A in the United States kick off a wave of violent civil disturbances throughout that nation's Sanctuary Districts, eventually leading to an end to the Sanctuary District system as internal conditions are revealed to the general populace. (DS9: "Past Tense")


  • The global destabilization of numerous nations leads numerous bands of eco-terrorists upset at the mismanaging of Earth’s biosphere to strike out at the weakened nations, leading to the deaths of 37 million people across the globe. In response to these attacks, the New United Nations (NUN) are formed, seeking progress towards a true United Earth. The ECON refuses to pursue membership in the NUN, seeing it as merely further attempts at re-asserting Western dominance. (ENT: "In a Mirror, Darkly, Part II")



  • The first successful manned mission to Mars — the Ares I, a joint NASA/ESA ship — arrives at the planet and makes landfall.


  • 6 Earth-crossing asteroids are prevented from colliding with the Earth by the joint efforts of the United States, the European Union, the Pan-African Alliance, the Muslim Bloc nations, and ECON, a rare moment of international cooperation. These asteroids are moved to Earth’s L5 point and hollowed out to serve as the shells for permanently-inhabited O’Neill colonies. (TLE Novel: The Sundered)
  • Lee Kuan becomes leader of the ECON, reorienting it onto a more militaristic footing and making no attempt at hiding his desires to wipe out the “Western imperialists” of the NUN and assert ECON as the dominant global power of Earth. (TLE Novel: The Sundered)


  • August: The Ares IV under the auspices of the International Space Agency - a joint multinational agency formed in the aftermath of the 2031 incident - reaches Mars, the fourth manned mission to that planet. While the two mission specialists land successfully, the orbital module disappears and is thought destroyed by a phenomenon detected as passing dangerously near Mars at the time, described by mission commander Lieutenant John Kelly in his last transmission prior to the capsule’s destruction as an unknown object over a kilometer wide but later identified as a graviton ellipse, Earth's first encounter with a spatial anomaly. The Ares V is rushed to launch to rescue the stranded astronauts, arriving within weeks and recovering them safely. (VOY: "One Small Step")


  • July 23: NASA launches the ESS Charybdis, the third attempt to explore beyond the solar system in an active manned vessel. (TNG: "The Royale")


  • Early 2038: Earth loses contact with the Charybdis. The ESS Jacob was later launched to discover its fate, to no avail. (TNG: "The Royale")


  • Inspired by the success of the L5 O’Neill colonies as proving that self-sufficient colonies are possible, the Luna colonies are founded, a growing interest in spaceflight and increasingly poor conditions on Earth encouraging many to seek out a better life elsewhere.


  • Despite efforts on both sides and continued cooperation in some endeavors, relations between the NUN (dominated by the US and EU) and the ECON continue to degenerate at frightening speed.


  • The final World Series game, featuring the New York Yankees against the London Kings, is played on Earth, to 300 attendees. (DS9: "If Wishes Were Horses"; Novel: Articles of the Federation)


  • The Hermosa Earthquake hits the western coast of North America; a devastating natural disaster, it wipes out much of Los Angeles, weakening an already-unsteady United States.



  • Early 2053: Recently-discovered oil fields in Antarctica and the Taklamakan Desert lead to a flare-up of hostilities between the NUN and the ECON.
  • May 1, 0230 UTC: The beginning of Earth's World War III, a global nuclear war that lasts for mere months, but ends in 600 million dead worldwide.


  • After ordering the euthanasia of hundreds of thousands of radiation-sickened people in an effort at “purifying” the human species, Colonel Phillip Green, one of the worst eco-terrorists of the 2026 attacks and the last holdout of the independent armies, is captured and placed on trial. While many considered him a genocidal madman, others saw him as a pragmatist seeking the best interests of humanity in purging likely-deadly mutations from the species’ gene pool and ending the suffering of the radiation-afflicted.


  • August 9: While taking part in an experiment that may potentially lead to an FTL breakthrough in conjunction with Earth Station Bozeman, all six L5 asteroid habitats vanish, presumed destroyed. (TLE Novel: The Sundered)



  • April 5: The launch of the first successful human warp-capable vessel, the Phoenix, designed and piloted by the brilliant physicist and engineer Zefram Cochrane from Earth Station Bozeman, leading shortly after to Earth’s first official contact with other intelligent life: a Vulcan scout vessel, the DFC T'Plana-Hath, that had detected the Phoenix’s warp signature while passing through the system. Earth is declared a protectorate of the Confederacy of Vulcan and soon begins to receive Vulcan aid, both humanitarian and ecological, which slowly reverses the worst of the damage suffered by the planet since WW3. The governments of Earth work to reconstruct themselves as news of First Contact spreads, a light of hope in the darkness and pessimism that’s settled on Earth since the revelation of the Eugenics Wars. (Movie: "First Contact")


  • Humanity begins work on a fleet of warp-capable ships with which to explore space.


  • The United Earth Space Probe Agency (UESPA) (an agency cobbled together by the weakened NUN from the remains of the International Space Agency and Project Phoenix) launches Friendship One, Earth’s first warp-capable probe. (VOY: "Friendship One")


  • Eta Cassiopeia III is chosen as the site for the first Human extrasolar colony. The SS Conestoga is launched; at warp speeds available at the time (below warp 1.5), the 19.43 ly journey takes 9 years to complete. (ENT: "Terra Nova")


  • Trill first emerges from isolationism and joins interstellar society, including first contact with Vulcans. (DS9 Short Story: "First Steps")


  • June 23: Terra Nova, Earth’s first extrasolar colony, is founded on Eta Cassiopeia III, the nearest uninhabited temperate world to Earth yet detected. Over the next few years, relations between Earth and the Novans grow strained as Earth attempts to gain an increasing hold over its extraterrestrial colonies and send a second ship to the Terra Nova colony, but these plans end when contact with Terra Nova is lost without explanation in 2083. The fate of the colony is not discovered for another 73 years. (ENT: "Terra Nova")


  • Despite Vulcan aid, the still-weak New United Nations collapse due to the chaos of the post-atomic horror and the anarchy that still ravages much of the planet, for now ending all thoughts of a United Earth; UESPA, however, manages to survive independently as an agency, largely due to the increasing presence of Earth in local space.


  • The Earth Cargo Service is established, a largely-independent body of long-haul cargo vessels governed by Earth Cargo Authority. These ships spend years at a time hauling cargo along trade routes, leading to an independent, frontier culture among its crews.


  • The SS Valiant, a civilian endeavor by UESPA led by ship's captain Carlos Tarasco, sets out in a planned multi-year exploration of distant space. (SGR Novel: The Valiant)


  • Defying UESPA’s colonization board, a large group of would-be colonists (including Zefram Cochrane) lead an attempt at settling Earth’s second extrasolar colony following the seeming disappearance of Terra Nova, selecting a more nearby location for their attempt: Alpha Centauri III, a borderline-habitable planet in orbit of Alpha Centauri A, suffering the aftereffects of an impact winter from a collision centuries prior, previously rejected by UESPA for just that reason. This attempt succeeds two years after launch in spite of the planet’s harsh conditions, marking the start of the Alpha Centauri Concordium. It is soon followed by colonies on a number of other worlds in the Alpha Centauri system, including Centaurus and Proxima Colony. A colonization boom followed soon after, leading to the founding of colonies on such worlds as Vega IX, Deneva, Tau Ceti IV, Eristas, and Gault.


  • December 30: The SS Valiant is caught in a magnetic storm and somehow swept beyond the galactic barrier, the first human ship to encounter that phenomenon. The ship ends up destroyed by Captain Tarasco two days later to end the threat of Geirrod Agnarsson, at the time undergoing accelerated barrier mutation. (SGR Novel: The Valiant)



  • July: The survivors of the SS Valiant, having drifted in a loose convoy near the galactic barrier since the ship's destruction, reach the planet on which they settle the city of Magnia, humanity's second extragalactic colony. (SGR Novel: The Valiant)

22nd century



  • The first Martian colonies are established.


  • The War of Martian Independence (also known as the Martian Revolution) begins with the Gundersdottir's Dome Rebellion. Following the rebellion was a protracted but bloody conflict that rocks Earth’s slowly-recovering global economy by disrupting sorely-needed interplanetary trade, and soon leads to the political independence of Mars from the nations of Earth. The War ends with the drafting of the Fundamental Declarations of the Martian Colonies, resulting in the formation of the Confederated Martian Colonies. (ENT Novel: Beneath the Raptor's Wing; TOS: "Court Martial"; TNG Novel: Rogue)



  • The Warp Five Complex is founded on Earth by Drs. Zefram Cochrane and Henry Archer, an institute devoted to the development of a M/AM warp drive capable of reaching Warp 5, in hopes that such a tremendous leap forward would unlock even more avenues of exploration and discovery in spite of what is seen by many on Earth as Vulcan reticence to, over the last 50 years, either stand alongside humanity as equals or allow humanity to stand on its own. Shortly after, Zefram Cochrane disappears, flying alone into the great unknown in a one-man warp ship. (ENT)
  • As a competing effort to Dr. Archer's Warp Five Complex, Dr. Victor Brodesser begins research into an alternate means of propulsion, the engine eventually termed the cascading ion drive. The two physicists have a long-term rivalry as each pursues their own divergent path into FTL propulsion. (ENT Novel: "Daedalus")





  • The government of United Earth is officially formed with the signing of the Traité d'Unification at the Place de la Concorde in Paris, France. (Novel: Articles of the Federation)
  • Along with United Earth, Earth Starfleet is established as an organization parallel to and working alongside the officially-unaligned UESPA, the branch of United Earth devoted to exploration of space.


  • The population of Theta Cygni XII is wiped out upon the arrival of blastoneuron parasites from Levinius V, their wave of insanity resulting in global war and chaos. A small number of survivors are coerced by the invading parasites to evacuate the planet in nuclear-powered sleeper ships, eventually arriving at Ingraham B some 130 years later. (ENT Novel: Live by the Code; TOS: "Operation: Annihilate!")



  • The cascading ion drive prototype Daedalus is launched, projected to have a top speed upwards of warp 7. Unfortunately, the cascading ion drive proves itself unstable, and the ship is lost with all hands. However, the design of the ship itself proves quite feasible, and after a redesign to support conventional M/AM warp drive, becomes the basis of the Daedalus class, the cornerstone of Earth Starfleet for decades to follow. (ENT Novel: Daedalus)


  • Starfleet’s NX program, an experimental program developed out of the Warp Five complex, first produces a prototype engine capable of breaking the Warp 2 barrier. (ENT: "First Flight")


  • The NX program achieves Warp 3. (ENT: "First Flight")


  • Deneva Colony is established on Kappa Fornacis III as a base for local asteroid miners; at the time, the most distant Earth settlement yet established. (ENT Novel: Beneath the Raptor's Wing)



  • July 14: The last three holdout nations of Earth — the United States of America, China, and Australia — sign the Traité d'Unification, making United Earth a true world government. (S31 Novel: Control)


  • April 12: Starfleet’s first Warp 5 vessel is launched, the Enterprise NX-01. (ENT: "Broken Bow")


  • February 25: The Paraagan II colony is destroyed by Suliban Cabal actions in an attempt at killing the ancestor of a temporal researcher of the 24th century, as a strike in the Temporal Cold War. (ENT: "Shockwave"; DTI Novel: Watching the Clock)
  • Vulcan/Andorian tensions begin to resolve as a result of mediation by the burgeoning interstellar nation of United Earth, via the diplomatic efforts of Captain Jonathan Archer. The conflicts are essentially resolved by the Babel negotiations of the 2154 that lead to the formation of the Coalition, though tension doesn't entirely cool until the late-22nd century. (ENT: "Cease Fire", "Babel")


  • March 22: Earth is attacked by a Xindi probe in the most devastating loss of life to the planet since World War 3; a prototype particle weapon strikes the Florida peninsula and carves a swath south, cutting through Cuba, Jamaica, Colombia, and Venezuela, with total casualties estimated at seven million. This attack leads to Earth Starfleet's Xindi mission within the Delphic Expanse, and is widely considered the first demonstration of United Earth's ability to stand alone as an interstellar power.
