This article plots the events which were shown or mentioned in the history of the Twelve Colonies from the Re-imagined Series and Caprica.

By convention, all dates are relative to the Fall of the Twelve Colonies. Events before the Fall are marked as "BCH", or "Before Cylon holocaust". Given the few and somewhat contradictory dates about the Colonials' ancient history and the exodus from Kobol, that part of the timeline is speculative.

The Cylon holocaust occurs more than 150,000 years ago.

Ancient History

See also: History of the Twelve Colonies, Sacred Scrolls

• Unspecified time period: Humans on the planet Kobol organize themselves into twelve tribes (TRS: "Miniseries"). According to at least one scripture, they "live in utopia with the gods." The humans become sufficiently advanced to establish viable space travel and artificial, robotic life. Artificial life-forms, machines similar in nature to the later day Cylons, are created by the humans. A war against the machines occurs. At one point the machines evolve and take humanoid form, either before, during or after the war. This group of humanoid Cylons are later referred to in the Sacred Scrolls as the "Thirteenth Tribe," although said text does not specify that they were a tribe of Cylons (TRS: "Sometimes a Great Notion").
• 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 Hopes on another planet This contradicts Ellen Tigh's statement that the temple was built 3,000 years ago (TRS: "No Exit"). They pray for guidance and are shown the way to Earth, the planet they colonize.
• ca. 3,600 years BCH: Pythia records her prophecies. Aside from reports of the landing on Earth and drawings of temples there, this book describes "the exile and rebirth of the human race" and a "dying leader" not making it to a "promised land," though how long before her writings that such events took place is not revealed.
• 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
• ca. 3,000 years to 2,000 years BCH: The humanoid Cylons of the Thirteenth Tribe prosper and begin to reproduce sexually. The technology of "organic memory transfer," or downloading, is abandoned.
  • The Thirteenth Tribe produce their own mechanical Centurions to act as laborers for their civilization.
• ca. 2,000 years BCH: (The order of events on Kobol and Earth is uncertain.)
  • Samuel Anders, Tory Foster, Ellen Tigh, Saul Tigh, and Galen Tyrol, later collectively known as the "Final Five," are born on Earth.
  • The Final Five work together in a research lab attempting to re-develop downloading technology. The effort is spearheaded by Galen Tyrol and Ellen Tigh.
  • All five Cylons receive visions of beings nobody else can see warning them of an impending rebellion by Earth's Centurion population. The Final Five prepare a resurrection ship and leave it in orbit.
  • The remaining Twelve Tribes leave Kobol and settle the Twelve Colonies.
  • Lord of Kobol "Athena" kills herself in despair over this. A tomb is built for her containing a 3-D projection showing Earth and its Zodiac. The projection is activated by the Arrow of Apollo, which travels with the twelve tribes.
  • The Centurion uprising occurs and the Thirteenth Tribe exterminates itself in a nuclear holocaust. Earth is left a nuclear wasteland. The Final Five die in the attack, and are resurrected on board their orbiting ship.
  • The Final Five begin a journey back to Kobol to find the other twelve tribes and inform them of Earth's fate. They are aware of the cyclical nature of history and believe that the twelve tribes will create Cylons again. They want to warn them to treat them right. However, their ship is not equipped with a conventional FTL drive and journeys at relativistic sublight speeds.
• 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.
  • The Final Five stop at the Temple of Hopes as they retrace their tribe's path.
  • The Final Five arrive at Kobol, finding the planet abandoned. They continue on in pursuit of the twelve tribes, heading toward the colonies.

Recent Colonial History

The most recent history could also be dated using the calendar from Caprica, but the method was not used in the re-imagined series and remained in the background even on the new show. Furthermore, it is not known whether the calendar is specific to the planet Caprica or common to the twelve worlds.

• At least 200 years BCH: Humans develop an immunity to the virus causing Lymphocytic encephalitis (TRS: "A Measure of Salvation").
• ca. 93 BCH: Tauron Civil War causes emigration of Joseph and Sam Adama to Caprica to live in an orphanage. Joseph later becomes a lawyer thanks to the education funded by the Ha'la'tha crime syndicate; Sam becomes an assassin for Ha'la'tha (CAP: "Pilot").
