* In a distant galaxy, a race of humans called the [[Alterans]] experience a fundamental split in cultural governance. The majority push for a religious focus, while a smaller group push for a scientific one. Fearing extreme persecution, the small Alteran group choose against using technology which could brainwash their brothers and depart in a ship for a galaxy to call their own. The scientific Alterans will henceforth be known as [[Ancients]].

* In a distant galaxy, a race of humans called the [[Alterans]] experience a fundamental split in cultural governance. The majority push for a religious focus, while a smaller group push for their people to follow a scientific path. Fearing extreme persecution, the small Alteran group chooses against using technology to effectively brainwash their brothers -- instead departing in a ship for a galaxy to call their own. The scientific Alterans will henceforth be known as [[Ancients]], and the religious zealots they left behind, the [[Ori]].

PRE-HISTORY

  • In a distant galaxy, a race of humans called the Alterans experience a fundamental split in cultural governance. The majority push for a religious focus, while a smaller group push for their people to follow a scientific path. Fearing extreme persecution, the small Alteran group chooses against using technology to effectively brainwash their brothers -- instead departing in a ship for a galaxy to call their own. The scientific Alterans will henceforth be known as Ancients, and the religious zealots they left behind, the Ori. ("Avalon, Part 2;" "The Fourth Horseman, Part 1;" The Ark of Truth)
  • At the time of their departure from their home galaxy, the Ancient Amelius begins to develop Stargate technology. (The Ark of Truth)
  • The Ancients make the Milky Way Galaxy their new home. They seed numerous worlds with Stargates as well as human life, and settle on a planet they name "Terra": Earth. ("Avalon, Part 2")
  • Some time later the Ori will eventually discover how to ascend, establishing the Origin religion and creating planets full of human worshipers to feed their need for energy.


3-50 MILLION YEARS AGO

  • The Ancients form an alliance with three other races in the galaxy including the Asgard, the Nox, and the Furlings. They establish a meeting planet on Heliopolis as a sort of galactic "United Nations." ("The Torment of Tantalus")
  • Proclarush Taonas is abandoned by the Ancients. ("The Pegasus Project")
  • A terrible plague cripples the peoples of the Milky Way, decimating Ancient colonies across space as well as on Earth. ("Window of Opportunity," et al)
  • The Ancients of P4X-639 engineer a time machine to go back before the plague to reverse it, but discover the flawed technology only goes backwards by 10 hours. They eventually deactivate the device and accept their fate. ("Window of Opportunity")
  • The Ancients create a device on Dakara to repair the damage caused by the plague. ("Threads")
  • The Ancients of Earth abandon their interests in the Milky Way and set course for the nearby Pegasus Galaxy in Atlantis. Ayiana, a carrier of the plague, is left behind. ("Rising")
  • The Dakara device activates to relaunch the Milky Way's evolution process. (Conjecture in relation to other events)
  • The Ancients arrive in the Pegasus Galaxy. As before, they create a network of Stargates and seed human life on numerous planets. Atlantis makes its home on the planet Lantea. ("Rising")
  • The Ancients establish a network of defense satellites in the Lantean System. ("The Defiant One")


HUNDREDS OF THOUSANDS OF YEARS AGO

  • The Ancients dispatch the Destiny into the far reaches of the universe to discover a signal they have located buried in the fabric of space-time since the dawn of creation. ("Air, Part 2")


c. 100,000 YEARS AGO


c. 30,000 YEARS AGO

  • A crew of Asgard depart their planet in suspended animation. At this stage in their development they are still capable of sexual reproduction. ("Revelations")


c. 15,000 YEARS AGO


c. 11,000 YEARS AGO

  • The Altairan (not to be confused with the Ancients) Hubbald establishes an underground complex on Altair to take the place of the planet's failing biosphere. ("Tin Man")


MORE THAN 10,000 YEARS AGO

  • Iratus bugs sample human blood in the Pegasus Galaxy and, mixing human DNA with their own, eventually evolve into the Wraith.
  • The Wraith develop as a sentient society, constructing ships and weapons to feed their hunger for human life essence.
  • The Ancients engage the Wraith in battle. Though they are superior in technology, the Wraith are superior in number. A 100-year war ensues. ("Before I Sleep")
  • The Ancients construct the Replicators as a weapon in the conflict with the Wraith, but the artificial life forms evolve rapidly. The Ancients eventually abandon the project and bomb the Replicator homeworld of Asuras -- but the "Asurans" survive, and begin to rebuild their civilization in the absence of their makers. ("Progeny")


10,000 YEARS AGO (8000 BC)

  • The Goa'uld Ra discovers the planet Earth via mothership and takes a host from the North African desert. He proceeds to abduct humans from across the planet to spread among the stars as slaves.("Stargate" the Movie)
  • The Ancient warship Aurora is sent to the outer rim of the Pegasus Galaxy to gather information concerning a weakness in Wraith defenses. Life support fails before they can return to Atlantis with the information they have obtained. The crew survive in stasis pods. ("Aurora")
  • An Ancient entrusts the Quindosim with a Zero Point Module. The Quindosim would eventually be culled by the Wraith. ("The Brotherhood")
  • Chaya Sar ascends and takes on the guise of Athar, goddess protector of Proculus. She lashes out with her ascended powers against the Wraith. Ascended beings in the Pegasus Galaxy punish her by forcing her to protect Proculus for all time. ("Sanctuary")
  • Unable to survive the overwhelming assault of the Wraith, the Ancients forfeit the 100-year war. They recall their forces to Atlantis for a final stand and create a window for Lantean refugees to return to Earth through the Stargate. Numerous ships reach the Lantean System but are destroyed. ("Before I Sleep")
  • Having narrowly escaped a catastrophic power failure in 2004, John Sheppard, Radek Zelenka, and Elizabeth Weir unwittingly trigger a time jump in a Puddle Jumper to this time period. After a fatal crash, Weir is the only survivor, recovered by the Ancients. ("Before I Sleep")
  • Having lost the war with the Wraith, the Ancients sink Atlantis deep beneath the Lantean oceans. Janus, the inventor of the time-traveling Puddle Jumper, disobeys the orders of the Council and leaves Elizabeth Weir in the city. She goes into stasis for 10,000 years, waking at intervals to regulate the city's power systems so that she may avert Atlantis's future power failure. ("Before I Sleep")
  • Realizing they have missed the evacuation of Atlantis, the crew of the Ancient warship Tria set a course for the Milky Way at light speed. ("The Return, Part 1")
  • The Lantean survivors, now on Earth, attempt to avoid influencing the primitive human tribes who now live there. Moros, Ganos Lal, and numerous other Ancients seclude themselves and learn to ascend, while over time the rest die out. ("The Pegasus Project")


6,700 YEARS AGO (4700 BC)


5,000 YEARS AGO (3000 BC)

  • Ishkur's elite force of Jaffa commanders rebel against him. He orders their deaths, but they flee in search of the mythical world of Kheb. The traitors find a secluded planet of their own and become the Sodan. ("Babylon")
  • SG-1 travels back in time and unwittingly participates in the uprising against Ra in Ancient Egypt, driving the Goa'uld System Lord from the planet. The rebels bury the Stargate at Giza so that it may be found in the future. SG-1's presence in the past is hidden from history. ("Moebius, Part 2")
  • After the human rebellion Ra loses interest in Earth. To prevent another uprising elsewhere, he outlaws reading and writing in Abydonian culture. ("Stargate" the Movie)

  • Sensing the growing threat of the Ori, the Ancient Moros abandons ascension to retake human form. Now known as Myrddin, he establishes an enclave of noblemen including Arthur and the Knights of the Round Table. During this period Myrddin, who retains his knowledge as an Ancient, is the most powerful human being on the planet. The other ascended beings order Ganos Lal to monitor him. She takes on the name of Morgan Le Fay. ("The Quest, Part 2")
  • Aware of the ongoing threat of the Ori in another galaxy, Myrddin creates phase-shifting technology to aid him in secretly developing a weapon capable of destroying ascended beings -- keeping it hidden from the Ancients. Realizing his intention to one day destroy the Ori, Morgan destroys the device and traps Myrddin within an isolated Stargate network. ("Arthur's Mantle," "The Quest, Part 2")


c. 750


c. 1000

  • The inhabitants of P7J-989 advance their technology too rapidly, and a chemical disaster renders the planet uninhabitable. Several citizens are placed in suspended animation within a bio-dome, their minds kept active by computer. ("The Gamekeeper")
  • Sokar visits Earth and captures a group of medieval Christians. ("Demons")
  • The alien race of PXY-887 end the oppression of the Goa'uld on their planet and take the guise of Spirits to live in harmony with the transplanted Salish tribe. ("Spirits")
  • Anubis is banished by the Goa'uld System Lords. Though they believe him to be dead, in fact he departs for Kheb, where the ascended being Oma Desala teaches him to ascend. The ascended collective witnesses Anubis's treachery and attempts to force him back to the mortal plane -- but they only succeed halfway. Now part ascended, Anubis departs the Milky Way Galaxy with the Ancient knowledge he has learned -- and Oma is punished for her actions. ("Last Stand;" "Threads")
  • The Asgard lose their ability to sexually reproduce, and adopt a "quick-fix" with cloning technologies. Though their scientists continue to work on the problem, genetic degradation is inevitable. ("Revelations")
