Imperial-Renegade Dalek Civil War

The Imperial-Renegade Dalek Civil War was a civil war across the Dalek Empire between two factions - Davros's Imperials and the Dalek Supreme's Renegades in the aftermath of the Dalek-Movellan War and was one of the causes of the Last Great Time War.

Origins
The Daleks broke into two factions shortly after the creation of the Daleks and the destruction of the Kaled City. The Daleks realised that Davros was impure as he was not 100% Dalek and was not their leader, so they turned against him and exterminated him. (TV: Genesis of the Daleks) The Dalek who fired on him was the Dalek Prime, who later became the Dalek Emperor. (PROSE: The Evil of the Daleks, War of the Daleks)

However, Davros survived and his body remained hidden beneath the ruins of the Kaled City. A group of Daleks decided that they needed Davros' help once again when the Daleks faced battle with the Movellans and the two sides found themselves at an impasse. The Daleks allied with Davros shortly after he was awoken by the Fourth Doctor.

Davros, incensed to learn that the Daleks were led by a "Supreme Dalek", vowed to "dispute [ the title] most vigorously" and claim the position of Supreme Commander, and ultimately Emperor, (WC: Risen) of his creations for himself. This created a faction of Daleks who recognised the legitimacy of Davros' claim to leadership and professed their loyalty to him. Nonetheless, the Doctor defeated most of the Daleks and had Davros frozen in suspended animation. (TV: Destiny of the Daleks) Davros was taken to a prison station, the Vipod Mor, where he remained frozen for 90 year s. (TV: Resurrection of the Daleks)

During Davros' imprisonment, the Movellans broke the impasse by releasing a virus which devastated the Dalek Empire, leading to its collapse across Mutter's Spiral. In the aftermath, several remaining Dalek commanders tried to reorganise what was left of their own isolated sectors. The result exacerbated the existing factionalism. (PROSE: Remembrance of the Daleks)

Rescue of Davros
In a bid to restore the Daleks to power, the Supreme Dalek concocted an ambitious plan to enact revenge on several of the Daleks' enemies. The three main objectives were:


 * Rescue Davros and manipulate him into finding a cure for the Movellan virus.
 * Infiltrate Earth using duplicates to destabilise the planet in preparation for another invasion.
 * Send duplicates of the Doctor and his companion s to Gallifrey to assassinate the High Council of the Time Lord s.

Davros was released by Gustave Lytton and his mercenaries recruited by the Supreme Dalek. Learning of the Daleks' defeat by a Movellan a bio-weapon, Davros used his virus research as a means to secretly convert humans and Daleks to his cause, eventually building up a small army. He sought to release the virus against the Supreme Dalek's forces and create a new race of Daleks loyal to him in its place. He claimed to the Fifth Doctor that he had made mistakes in making the Daleks completely ruthless and unable to think illogically, and he decided to make them understand emotion, but only in order to make them better killers.

Soon, Davros's converted army came into conflict with the Supreme Dalek. Both sides nearly wiped each other out, and were ravaged by the virus. Davros himself was also infected by the virus (TV: Resurrection of the Daleks) but survived and fled in an escape pod before his space station blew up. (TV: Revelation of the Daleks) The Supreme Dalek had also fled the station and survived the explosion. (PROSE: Resurrection of the Daleks)

Necros
Davros escaped to the planet Necros, where he began creating a new army of Daleks from human tissue. The Daleks led by the Supreme Dalek were alerted to Davros' presence by Takis and Lilt, two employees at Tranquil Repose. The Dalek Supreme's forces considered Davros a criminal. When they arrived, a short engagement between Davros' and the Supreme Dalek's forces ensued. Following his capture, Davros attempted to reveal the identity of the Sixth Doctor to the Daleks, but he was not recognised by the Supreme Dalek's forces (who had encountered his previous incarnation). Davros was taken to be transported to the Dalek homeworld of Skaro to stand trial. (TV: Revelation of the Daleks)

Journey to Skaro
En route to Skaro, the ship carrying Davros crashed on the planet Lethe. Davros was rescued and set himself up as "Professor Vaso", altering the perceptions of the humans on the colony so they would not recognise him as the "Great Healer". He attempted to create a new machine, a Juggernaut based on a Mechanoid design.

Lethe's atmosphere prevented the Supreme Dalek retrieving Davros directly, but its forces intercepted the Sixth Doctor's TARDIS and forced him to serve as an agent of the Daleks to stop Davros' research and manipulations. The Doctor discovered two of Davros' Necros Daleks had survived the crash, but were destroyed following Davros' final gambit on the colony and the Supreme Dalek's intervention. (AUDIO: The Juggernauts)

The New Emperor
While on Skaro, the Sixth Doctor rescued Davros just before the Daleks carried out their sentence of death and spoke to him of his future destiny as Emperor Dalek. (COMIC: Emperor of the Daleks!, Above the Gods) The Doctor took Davros to Spiridon, where he could lick his wounds and bide his time. The Doctor intended to lay the groundwork for a Dalek civil war and spoke to Davros of his future destiny as Dalek Emperor.

When the grey Renegades led by the Supreme Dalek landed on Spiridon with the next incarnation of the Doctor, Davros set his army of white and gold Daleks (later known as the Imperial Daleks) against them, along with a Special Weapons Dalek. The Supreme Dalek died and in the aftermath of the battle, Davros found his wheelchair damaged. He suffered amnesia, remembering only his ambition to make himself the new Emperor. (COMIC: Emperor of the Daleks!)

Conflict on Earth
By the Shoreditch Incident, the Renegade Daleks were fragmented, with certain factions not engaged in the conflict with the Imperium; (PROSE: Remembrance of the Daleks) indeed, some of the Dalek Prime's Daleks, even after the war, were sympathetic to Davros's side. (PROSE: War of the Daleks) The Supreme Dalek at the time hoped to rally them by killing the Seventh Doctor. (PROSE: Remembrance of the Daleks)

The war ended after a final battle on Earth in 1963. Davros' Imperial Daleks defeated the Renegades with the aid of the Special Weapons Dalek. Further pursuing the plan he had already developed, the Seventh Doctor destroyed the Imperial Dalek mothership, and Skaro itself, using the Hand of Omega. The Doctor convinced the last of the Renegades on Earth to destroy itself by telling the Dalek that it no longer had a purpose. (TV: Remembrance of the Daleks)

The Civil War had briefly become part of the Last Great Time War when, after being manipulated by a Dalek duplicate, Susan Foreman arrived in the Shoreditch Incident to take the Hand of Omega. Though she was confronted by the renegade faction, she was saved by the Eighth Doctor. The incident played out as it was supposed to, and he returned her to Time War-era Kasterborous. (AUDIO: The Shoreditch Intervention)

Conclusion of hostilities
The Daleks ultimately survived the Shoreditch Incident. Accounts disagreed, however, on which side could be said to have emerged victorious from the Civil War.

According to some accounts, the Imperial Dalek fleet was destroyed alongside Skaro and the mothership, (PROSE: War of the Daleks, AUDIO: Terror Firma) but another suggested that only Davros had been lost. Hence, the Imperial Daleks had simply elected a new Emperor before moving forward with Davros's long-held plan of moving against Gallifrey — thus beginning the Last Great Time War. (PROSE: Dalek: The Astounding Untold History of the Greatest Enemies of the Universe) Yet a different account of the post-Shoreditch-Incident history of the Daleks suggested that Davros, sole survivor of the Incident, had created a new race of Imperial Daleks loyal to him, with him once more their Dalek Emperor, on Earth. (AUDIO: Terror Firma)

Another account, however, held that Davros awoke from stasis in his escape pod to find that Skaro was still whole and under the control of the Daleks of the Dalek Prime — those who had been designated Renegade Daleks during the Civil War, although, now that the "illegitimate" Emperor Davros was believed dead, they had reverted to calling themselves the true Imperial Daleks. The Dalek Prime further succeeded in weeding out those of his Daleks who, while genetically pure, were swayed by Davros's side politically. With Davros even seemingly being executed by the Prime's Daleks, the once-Renegades emerged the clear victors of the Civil War. (PROSE: War of the Daleks)

According to the events leading up to the Battle of Mordeela, after this Civil War was lost by both sides, one member of the Dalek Supreme Council exterminated all of the other members and elevated himself to the position of Emperor Dalek. This Emperor would then forge the Restoration Empire. Coming across a warning from a future Dalek unit regarding the Time Lord Victorious, the Emperor Dalek would enter into an uneasy alliance with the Eighth Doctor and enter the Dark Times, where they would enter a war with the Tenth Doctor's Victis Fleet in an attempt to stop him from changing history. (PROSE: The Restoration Empire, The Knight, The Fool and The Dead et al)

During the Last Great Time War, the Time Lords investigated using the split in the Dalek hierarchy to their advantage, considering an alliance with a single Dalek faction. They were dismayed to learn from their tactical team that the Daleks were once more united and that there was no possibility of engineering division within their ranks.
