Editing Timeline (TOS)

{{timeline series}}

The '''timeline''' below chronicles the events depicted in the [[Original Series]].

This timeline excludes the [[spin-off]] series ''[[Galactica 1980]]'' and does not include any information from [[separate continuity]] works such as novels and comics. The inaccurate ''[[Encyclopedia Galactica]]'' reference released in 1979 is noted here, but in a separate section for reference; it should not be used in articles unless properly compartmentalized.

The timeline is given in [[yahren]]s, the Colonial term for "years."  The date around which the timeline revolves is 7322, the only date given in the series, and one from the Colonial calendar. This was the yahren when the [[Cylons (TOS)|Cylons]] [[Thousand Yahren War|attacked]] [[Umbra]] on [[Caprica (TOS)|Caprica]], as mentioned during [[Starbuck (TOS)|Starbuck]]'s interview with [[Zara]] {{OS|The Man with Nine Lives}}.

==Ancient history==

* '''Before 1:''' The [[Beings of Light]] intervene at the beginning of human development on the planet that would come to be known as {{TOS|Kobol}}. {{TOS|Adama}} refers to these beings as the "Mother Race" {{OS|War of the Gods, Part I}}.
* '''1:''' The beginning of the Colonial calendar.
* '''~1342:''' The beginning of recorded human history on Kobol; 6,000 yahrens before "[[Saga of a Star World]]".

* '''~5432:''' [[The Twelve Colonies of Man|The Twelve Colonies]] begin to re-establish their space travel capabilities. At this time, the Colonials were using [[Propulsion (TOS)|sublight]] craft reminiscent of the early space vehicles launched from Earth in the 1960s and 70s {{OS|The Hand of God}}. According to Adama, "It took them hundreds of yahrens to revive even the most primitive crafts" <sup>([[Lost Planet of the Gods, Part II]], telemovie only)</sup>.
* '''~6342:''' 
** The [[Cylons (TOS)|Cylons]], a humanoid race, are taken over by their robot slaves. A machine ruler, known as the [[Imperious Leader]], comes to rule the [[Cylon Empire]] {{OS|War of the Gods, Part II}}.

* {{inlineref|7322}}: The [[w:epoch (reference date)|epoch]] of this timeline. After one of the first Cylon attacks on Caprica, the people of the farm village of [[Umbra]] are scattered. Chameleon is separated from Starbuck, who is later found alone at the edge of the [[Thorn forest]]; Chameleon notes that his wife was killed in the raid and his "baby son"<ref>It is entirely possible that this is an exaggeration, as [[Chameleon]]'s proclivities as a con artist make him an [[w:Unreliable_narrator|unreliable narrator]].</ref> (Starbuck) went missing  {{OS|The Man with Nine Lives}}.
* {{inlineref|7340}}: 
** The [[Fifth Fleet]] engages the Cylons at the [[Battle of Molecay]]. Battlestar ''{{TOS|Pegasus}}'' is the only Colonial vessel to survive. Commander [[Cain (TOS)|Cain]], realizing there will be Cylons lying in wait along the entire route back to the Colonies, orders ''Pegasus'' out into deep space 2 yahrens before "[[The Living Legend, Part I]]".
* '''7340-7342:''' ''{{TOS|Pegasus}}'' heads out into deep space, eventually winding up in the [[Delphian Empire]], which is in the process of falling to the Cylons {{OS|The Living Legend, Part I}}.

{{mainarticle|Timeline (1980)}}

The period between the [[Original Series]] and ''[[Galactica 1980]]'', and the episodes and events of the ''Galactica 1980'' happened in this period. Of course, as Battlestar Wiki treats ''1980'' as a divergent continuity, and thus a [[Timeline (1980)|separate timeline page is available]].
