Timelines of the Battlestar Galactica series


This article attempts to plot the events illustrated or mentioned in the history and prehistory of the Twelve Colonies in the Re-imagined Series.

All dates use the day of the Fall of the Twelve Colonies as the central time marker for all events in the series. Items that occur before the Fall are marked as "BCH", or "Before Cylon holocaust".

Ancient History[edit]

  • Over 17,000 years BCH: A supernova creates the Ionian nebula
  • ca. 4,000 years BCH: The Thirteenth Tribe reportedly leaves Kobol and builds the Temple of Five on another planet [1]
  • ca. 3,000 years BCH: A beacon is left at the Lion's Head Nebula, later marking the way to Earth. At some undated point, someone travels from Earth to Kobol, passing on information about Earth, including a map of its night sky [2]
  • ca. 3,600 years BCH: Pythia records her prophecies
  • ca. 2,000 years BCH: The remaining Twelve Tribes leave Kobol [1]
  • 2,000 years to 52 years BCH: The Twelve Colonies grow and prosper. Each colony acts as a sovereign nation, complete with inter-colonial wars

  1. 1.0 1.1 In "The Eye of Jupiter", Tyrol says that the temple is at least 4,000 years old. This is the oldest date noted in the series's timeline, but also conflicts with the prior date of Pythia and her works as described by Elosha in "Kobol's Last Gleaming, Part I", where she notes that the exodus of all 13 tribes occurred approximately 2,000 years ago.
  2. Doctor Cottle notes that the virus is identical to one recorded 3,000 years ago. While this makes the dating uncertain, it is the only clue to the beacon's age. That someone traveled back to Kobol is speculation, but an explanation for how Earth's sky could be displayed there. If true, it is still unknown on which of these two voyages the beacon was left behind.
  3. Doctor Cottle notes the time as "a couple hundred years ago", which is a indeterminate amount of time, but likely less than four or five hundred years.
  4. At the time of the Cylon attack, Tyrol has "ten years experience" (Miniseries), and has "served on battlestars since I was 18" (Resistance). This puts his birth in approximately 28 BCH, allowing for a few years leeway with the first comment.
  5. The podcast for "Scattered" places their meeting "twenty years ago". In "Torn", Adama states that he has known Tigh for 30 years. Furthermore, Adama's dossier places his reinstatement into the Colonial Fleet at 23 BCH. Battlestar Wiki choses to use the more consistent dates.
  6. 6.0 6.1 6.2 This date is assumed as follows: Zak died 2 BCH. Since he graduated from some kind of military academy, he would at least 22 years old, following real world models. On a photograph of William Adama with his sons, Lee seems to be about two years older than Zak. Adama and his wife probably met not long before Lee's birth.
  7. The time between Adama's and Tigh's reinstatement is not specified on screen. The February/March issue of Battlestar Galactica: The Official Magazine gives it as two years: "Adama reenlisted with the service and Tigh spent two years drinking before Adama pulled strings to get him back into service."
  8. While dialogue from "Hero" places these events at 1 BCH, this contradicts previously established dates about the time Adama and others served on Galactica. See Hero#Analysis for a detailed explanation why Battlestar Wiki chooses to treat this as a continuity error and change the date.
  9. Since Adama states that Tyrol has been under his commander for "over five years", this might also be one year earlier.
