Dalek Civil War

The Dalek Civil War was a civil war fought on Skaro between the Daleks loyal to the Dalek Emperor and the humanised Daleks, who had been implanted with the Human Factor.

The war was instigated when the Second Doctor implanted the Human Factor into a group of Daleks who became friendly to the Doctor and whom the Time Lord named Alpha, Beta and Omega. The Doctor tricked the Emperor into believing he would implant the Dalek Factor into these Daleks and eliminate the threat. Instead, the Doctor rigged an archway in the Dalek city, causing it to instil the Human Factor in every Dalek that passed through it. Those Daleks who passed through the archway turned on the Emperor and a battle broke out.

The fighting spread to the throne room amid the Emperor's protests and declarations. The Emperor himself was probably destroyed, although a blinking light on his casing may have indicated his survival.

The Dalek City was devastated by the conflict and began to explode. The Doctor believed this battle to be the Daleks' finish. (TV: The Evil of the Daleks)

Alpha was one of the last survivors of the short-lived "civil-war." (COMIC: Children of the Revolution)

Behind the scenes

 * The name "Great Civil War" was used to refer to the conflict in REF: Doctor Who: Aliens and Enemies, which also referred to the Last Great Time War as the "Great Time War", so the book's accuracy is questionable.
 * In GAME: City of the Daleks, the Eleventh Doctor tells Amy that the last time he visited Kaalann, it was in ruins and the Daleks had fled, suggesting the civil war took place on Kaalann, although he may also have been talking about the Time War. The Dalek Handbook also states that the Dalek City was named Kalaann.

The Dalek Handbook
According to the non-narrative material REF: Doctor Who: The Dalek Handbook, the Dalek Emperor survived. The humanised Daleks were defeated by the Emperor's Daleks, and the race began to rebuild.

Doctor Who: Battles in Time
According to non-narrative information in DWBIT 35, the war was fought around the same time as the defeat of the Seventh Dalek Armada at the battle of Gurnian. An account of the conflict was taken by a Dokktor Whit-Arkker in his document entitled 'The End of the Daleks'. These Daleks were depicted in the magazine as being of the 2005-2010 design.
