The '''Thousand-[[Yahren]] War''' is the primary conflict between the [[Cylon Empire]] and an intergalactic federation including the [[The Twelve Colonies of Man|Twelve Colonies of Man]]. 

[[Battle of Hasari|This conflict]] began when the Colonies aided the [[Hasari]] in taking back "their nation" from the Cylons.<ref>See [[#In the separate continuity|the separate continuity section]] of this article for differences between the novelization and the actual canon versions.</ref>  The exact nature of the Hasari and their relationship to the Colonies remains unknown {{OS|Saga of a Star World}}.

== Battles of the War ==

The following were known events during this conflict, in chronological order:

* [[Battle of Cosmora Archipelago]]: This is the earliest known conflict, with Commander [[Kronus]] and the [[Fourth Fleet]] victorious against the Cylons {{OS|Take the Celestra}}
* [[Battle of Caprica]]: This occurred during [[Leda]]'s lifetime {{OS|The Gun on Ice Planet Zero, Part I}}
* [[Attack on Umbra]]: A Cylon attack on Caprica, presumably on Caprican agricultural resources, which leaves [[Starbuck (TOS)|Starbuck]] and several hundred children orphaned {{OS|The Man with Nine Lives}}
* [[Battle of Molecay]]: This is the last known major battle with the Cylons. The [[Fifth Fleet]], lead by the "legendary Commander [[Cain]]," is destroyed here, save Cain's battlestar, ''{{TOS|Pegasus}}'' {{OS|The Living Legend, Part I}}
* [[Battle of Cimtar]]: The final coup de grâce, resulting in the fall of the Twelve Colonies {{OS|Saga of a Star World}}.

== Effects of the War ==

Given the war's duration, it appears that efforts normally occurring during peacetime were curtailed. [[Apollo (TOS)|Apollo]] mentions to [[Zac]] that they would be able to resume deep space exploration should there be peace with the Cylons {{OS|Saga of a Star World}}. The ''[[Rising Star (TOS)|Rising Star]]''&#39;s [[maitre d']] states that the festivities during the departure from their [[Cyrannus (TOS)|home galaxy]] remind him of a "time before the war" {{OS|The Long Patrol}}. This might suggest that there were lulls between major battles of reasonable length, or he might very well have been speaking of the time before the exodus from the Colonies.

In addition, the Colonials set up numerous colony worlds far outside their galaxy, which included the prison planet of [[Proteus]] {{OS|The Long Patrol}} and agricultural settlements such as [[Sectar (planet)|Sectar]] {{OS|The Magnificent Warriors}}. These planets became cut-off from the Twelve Colonies, resulting in a loss of technological advancement, even regression; Proteus, for instance, uses [[Sixth-millennium starfighter]]s that predates the mainstay seventh millennium Colonial {{TOS|Viper}} {{OS|The Long Patrol}}, heavily suggesting that the war took its toll on the supply and transportation lines between the main colonies and their smaller intergalactic interests to the point where whole worlds and outposts were forgotten about.

== Conclusion ==

The Thousand-Yahren War ends at the [[Battle of Cimtar]]. Lord {{TOS|Baltar}}, a Colonial double-agent for the Cylons, tricks President [[Adar (TOS)|Adar]] into believing the Cylons wished to negotiate a truce. The peace conference is a ruse, allowing a force of one thousand {{TOS|Raider}}s to destroy four of the five battlestars, including Adar's ''[[Atlantia (TOS)|Atlantia]]'', while a [[Basestar (TOS)|basestar]] fleet (and additional Raiders) destroy the [[The Twelve Colonies of Man|Twelve Colonies]] {{OS|Saga of a Star World}}.

With Baltar's agent, [[Karibdis]], neutralizing the Colonial defense systems on Caprica, the Cylons are able to attack the planet without planetary resistance {{OS|Murder on the Rising Star}}. Strafing runs and [[pluton poisoning|pluton bombs]] are used to devastating effect by the Cylon assault forces.

The final attack takes several [[centares]]. Reports transmitted from [[The Twelve Colonies of Man|Sagitaria]] indicate that it was "in flames," which is likely the same situation echoed throughout the Colonies.

As an end result, countless<ref>On page 16 of ''[[Encyclopedia Galactica]]'', a [[non-canon]]ical publication issued in 1979, gives the number of 70 billion. No exact number is provided in the series.</ref> humans are killed and the Colonies are neutralized as a home for the Colonials.

From the ruins of the Colonies, surviving Colonials are gathered into a motley fleet of [[The Fleet (TOS)|220 civilian ships]] and are escorted to safety by the last surviving battlestar, ''{{TOS|Galactica}}'' {{OS|Saga of a Star World}}.

== In the separate continuity ==

In the Berkley novelizations, {{alt|Adama|TOS}} states in his journal that the conflict began when the Cylons attacked Colonial merchant ships (destroying them by the thousands) and, later on, sent an attack fleet to the [[The Twelve Colonies of Man|Twelve Colonies]].
