The War Doctor
The Time War, more specifically called The Last Great Time War, is a conflict within the fictional universe of the British science fiction television series Doctor Who. The conflict pitted the Time Lords against the Daleks and culminated in the apparent mutual destruction of both races, caused by the Doctor.
In the Doctor Who continuity, the war occurs between the events of the 1996 film and the 2005 revived series. It was frequently mentioned and alluded to from the first series of the show's return, but was not directly seen until the show's 50th anniversary special. The war's events and progression have never been fully explained. Short comments in various episodes act as hints, but the war was not thoroughly talked about until the 2007 series finale; the two-part special The End of Time (2009) provided further information and revealed the Time Lord leaders' sinister endgame. The closing battles and the climax of the Time War were finally depicted in the 50th anniversary special "The Day of the Doctor" which ultimately revealed the Time Lords' fate.

The Last Great Time War
The Last Great Time War pitted the Time Lords of Gallifrey against the Daleks of Skaro. The specific incident that sparked the conflict remains unclear, but according to executive producer Russell T Davies, the origins dated back to the encounters of the Doctor with the Daleks. In Genesis of the Daleks (1975), the Time Lords—having foreseen the possibility of the Daleks conquering the universe—send the Fourth Doctor into the past in an attempt to avert the Daleks' creation, affect their development to make them less aggressive or discover an inherent weakness they could exploit.
In retaliation for this ultimately unsuccessful mission, the Daleks attempt to infiltrate the High Council of the Time Lords with duplicates of the Fifth Doctor in Resurrection of the Daleks (1984), followed by an open declaration of hostilities by one of the Dalek Emperors in Remembrance of the Daleks (1988).
Two specific events led up to the outbreak of the war: a peace treaty was attempted by President Romana under the "Act of Master Restitution" (a possible reference to the otherwise-unexplained trial of the Master on Skaro at the beginning of the 1996 television movie). This attempt was followed by the "Etra Prime Incident" (The Apocalypse Element), which some say "began the escalation of events". Weapons used by the Time Lords included Bowships, Black Hole Carriers and N-Forms (the last from Davies' 1996 New Adventures novel Damaged Goods), while the Daleks wielded "the full might of the Deathsmiths of Goth" (from the comic strip story Black Legacy by Alan Moore and David Lloyd, in Doctor Who Weekly #35–#38 (1980)), and launched a massive fleet into the vortex led by the Emperor (possibly in The Time of the Daleks).
The 'duration' and extent of the War remains unclear. Figures for its length range from at least several years to thirty thousand years, though such numbers are tentative, as time itself was bent and mutilated by the effects of the War. The statement made by Jack Harkness in "The Parting of the Ways" – confirmed by the Doctor – that the Daleks "vanished out of time and space" to fight the War would indicate that it was not waged in normal space-time. At some point, however, the conflict engulfed a sufficient bulk of the cosmos for a character to declare that the Daleks and Time Lords had not yet succeeded in their efforts to destroy it - some of it was "still standing". Several races hostile to the Time Lords, e.g. the Sontarans, wished to participate but were forbidden to do so.
The Doctor claims to have fought on the front lines and was present at the Fall of Arcadia. Arcadia was Gallifrey's second city fortified with four hundred "sky trenches". These were thought to be impregnable until an invading Dalek squadron swept them away (as seen in the 2013 minisode "The Last Day"). The 2013 minisode "The Night of the Doctor" reveals that at first the Doctor (at this point the Eighth Doctor) refused to take part in the war, even as it spiralled out of control and threatened to destroy the universe, instead working to help where he could but refusing to fight. This led him to attempt to save a woman from a spaceship crashing towards the planet Karn, who refused his aid because he was a Time Lord (as she claimed she couldn't "tell the difference" between the two species any more, implying that the Time Lords were just as destructive as the Daleks). The Doctor was killed in the crash, but was restored to life temporarily by the Sisterhood of Karn, who finally convinced him that for the sake of the universe, he had to take a stand and fight. They further offered an elixir that would control his regeneration and allow him to take a form best suited for the task. The Doctor accepted, remarking that there was no need for a Doctor in a universe consumed by war and requested that the Sisterhood make him a "warrior". He drank the elixir and regenerated into the War Doctor, declaring himself "Doctor no more."
Davros, the creator of the Daleks, also fought during the war after his creations, which had turned against him during Genesis of the Daleks but caused his revival in Destiny of the Daleks, rehabilitated him to a leadership position. In the first year of the War, Davros' command ship was seemingly destroyed at the Gates of Elysium after flying into the jaws of the Nightmare Child. Unbeknownst to the Doctor, who had tried to save him, Davros was rescued by Dalek Caan, who had escaped the events of Evolution of the Daleks (2007) via an emergency temporal shift.
The war resulted in countless millions dying endless deaths, as time travel was used by both sides to reverse battles that caused massive fatalities on both sides. These excesses of temporal warfare eventually led to the whole of the conflict becoming "time-locked", so that no time traveller could go back into it. The Doctor described the final days of the war as "hell", featuring "the Skaro Degradations, the Horde of Travesties, the Nightmare Child, the Could-Have-Been King with his army of Meanwhiles and Never-Weres".
As the war progressed the Time Lords became increasingly aggressive and unscrupulous. Growing in desperation, they accessed a cache of forbidden doomsday weapons fashioned by the ancients of Gallifrey known as the Omega Arsenal. All were wielded against the Dalek menace save one: "the Moment". Moreover, they resurrected the Master, a renegade Time Lord and nemesis to the Doctor, as they believed him to be the "perfect warrior for a time war"; it is implied that they gave him a full new set of regenerations.. However, after the Dalek Emperor gained control of the Cruciform, the Master deserted his post, used the chameleon arch to disguise himself as a human and escaped to a time period shortly before the end of the universe. Genetically a human, he escaped the destruction of all Time Lords as well as detection by the Doctor – who was unaware of his resurrection in the first place. The Master also remained ignorant of the latter phase and outcome of the war until he emerged from hiding, when he was told by the Doctor many years later.
Leadership among the Time Lords remained vague during the earlier phase of the war. Especially the role of the Doctor's former companion, Romana – President of the Time Lords according to later novels, audio dramas and comic series – was avoided. Ultimately, Rassilon, founder of the Time Lord society and its time travel technology who had discovered the secret of immortality, returned to assume leadership as Lord President, a position he was first to hold. Refusing the possibility of his civilization being destroyed by the Daleks, Rassilon prepared a doomsday scenario, the so-called "Ultimate Sanction". This genocidal scheme included sacrificing all of time itself, thereby destroying the Daleks and all life in the universe. The Time Lords themselves would have transcended into a non-corporeal collective consciousness that would be the only sentient form of life in existence. The Time Lords, apparently hardened by the horrors of war, gave near-unanimous support for this plan – only two Time Lords dissented when the issue was put to a full vote. Prior to the vote, when one of the Council, the Partisan, suggested shelving the Ultimate Sanction and that it may be better if Gallifrey were destroyed, Rassilon disintegrated her.
While the High Council continued to lead Time Lord society during the war, a separate War Council was tasked with overseeing the war itself, as well as Gallifrey's defenses. The War Council was led by an unknown Time Lord general. During the last days of the Time War, the War Council apparently became disillusioned with the High Council. 
On the last day of the Time War, the Dalek fleets surrounding Gallifrey launched what was said to be their biggest attack ever on the planet. The ten million Dalek ships subjected Gallifrey to a massive orbital bombardment and deployed numerous Daleks to invade the surface. Dalek forces captured the city of Arcadia, then laid siege to the capital itself. However, they were unable to break through the capital's sky trenches. Upon learning of Rassilon's "Ultimate Sanction", the War Doctor stole an ancient Gallifreyan weapon known as the Moment, or the Galaxy Eater, and intended to reduce Gallifrey into "rocks and dust" with the inferno wiping out the Dalek fleet. By this point, the entire period of war had become "time locked", so that no time traveller could enter or exit it.
Fearing that the Doctor would use the Moment, Rassilon and his fellow councilors attempted to escape the Lock by retroactively planting a four-note drumbeat (the rhythm of a Time Lord's heartbeats) into the Master's brain as a child and cause his descent into madness. From there, once the signal is made tangible enough, a Whitepoint Star, a diamond only found on Gallifrey, is used to create a link between the final day of the Time War and Earth in 2009 so the Master could release Gallifrey from the Time Lock. The plan ultimately failed, as the Doctor destroyed the diamond link and the Master apparently sacrificed his life to take revenge on Rassilon, sending the Time Lords back to their apparent doom. Unknown to almost everyone involved however, this was not the final end of the Time Lords. As "the Moment" had a will of its own, it showed the War Doctor an alternate solution and ultimately enabled all incarnations of the Doctor to gather to save Gallifrey by freezing it in time and removing it from the universe. The sudden disappearance of Gallifrey left the Daleks firing upon and subsequently annihilating themselves, while the Time Lords remained, albeit powerless and forgotten.
As the War Doctor's regeneration into the Ninth Doctor wiped out the memory of him saving Gallifrey as a means for his timeline to correct itself, the Doctor was haunted with the false knowledge of his home planet's demise with even some of his enemies like the beast of the Pit using that guilt against him. The Doctor's later incarnations even displayed a self-loathing towards their War Doctor incarnation before the Eleventh Doctor and Tenth Doctor learned the truth and accepted him as a legitimate Doctor incarnation. Though the destruction of both races marked the end of the war, the Ninth Doctor learns of the Dalek Emperor's survival with Rose wiping both him and his fleet in "The Parting of the Ways" as Bad Wolf while proclaiming the final end of the War. This is affirmed by the Tenth Doctor, who describes to Jack Harkness in "Utopia" that his resurrection by Rose was part of the final act of the War.
Removal of the Time Lords
Following what was for all intents and purposes the removal of the Time Lords, the Doctor believed himself to be the last of his race. The removal of the Time Lords also had a profound impact on time travel. In the 2006 episode "Rise of the Cybermen" when the Doctor, Rose Tyler and Mickey Smith are trapped in an alternative reality, the Doctor explains that, when the Time Lords were around, travel between parallel universes was less difficult but, with their demise, the paths between worlds are now closed. The Time Lords could also prevent or repair paradoxes such as the one created by Rose in an attempt to save her father's life in a traffic accident. After the Time Lords' demise, such a paradox summons the terrifying Reapers, who descended to "sterilise the wound" in time by devouring everything in sight, and are only stopped by Pete Tyler killing himself.
Because of the Time Lock, along with the danger of creating a paradox, the Doctor is prevented from going back in time and saving the Time Lords. He warns another character against trying to alter his own timeline as such meddling would "destroy two-thirds of the universe" and resists an offer by Krillitane Headmaster Finch, using the Skasis Paradigm, which would have given the Doctor the ability to reorder the universe and allowed him to stop the war. The Doctor would only change his decision and assure his race's survival after contributing to it as the Eleventh Doctor during the events of "The Day of the Doctor".
Throughout Series 5, the Eleventh Doctor encounters cracks in "the skin of the universe". The Doctor learns that the cracks, which erase those they consume from history, are a result of the Silence causing the Doctor's TARDIS to explode on 26 June 2010. During the events of "The Big Bang", the Doctor manages to close all the cracks using the TARDIS explosion and the Pandorica to produce a second Big Bang that restores the universe. During the events of "The Time of the Doctor", the Doctor discovers one remaining crack on the planet Trenzalore, through which the Time Lords transmit a "truth field" that ensures that all inhabitants speak the truth, along with the First Question: "Doctor Who?". The intention is for the Doctor to give his true name, which will verify to the Time Lords it is safe for them to return to the universe. Fleets of former War participants have gathered in Trenzalore's orbit to either prevent the Doctor from speaking his name, or resume the War if the Time Lords return. The Church of the Papal Mainframe becomes the Silence as a dedication to keeping the peace, and a chapter of the Silence (led by Madame Kovarian) are discovered to be responsible for the TARDIS's explosion (paradoxically creating the cracks in the first place) and the attempted murder of the Doctor at Lake Silencio in Utah, 2011 (The Impossible Astronaut, The Wedding of River Song). In the end, the Time Lords remain in exile and close the remaining crack, but not before heeding Clara's plea for them to save the Doctor, old and weary from his years protecting Trenzalore, granting him a new cycle of regenerations, which allow him to destroy the Dalek fleet surrounding the planet.
Remnants of the Daleks
Despite the Doctor's efforts, not all Daleks perished in the war. The Ninth Doctor encounters a single, dysfunctional Dalek in a museum on Earth in 2012, which had apparently been on Earth for 50 years. It is eventually convinced to commit suicide after gaining human feelings via Rose Tyler touching it. The Doctor later discovers that the Dalek Emperor itself had also survived, and had gone on to build a whole new Dalek race, using the organic material of human cadavers by completely rewriting their DNA. The destruction of the Emperor and its fleet in the year 200,100 during an attack on Earth at the conclusion of the 2005 series by a time vortex-augmented Rose Tyler is accompanied by her declaration that "the Time War ends".
The elite Cult of Skaro also survived by fleeing into the Void between dimensions and survived the original end of the Time War, taking with them the Genesis Ark, a Time Lord prison ship containing millions of Daleks. The new Dalek army released from the Ark on Earth 2006 – after the Ark is touched by a time-traveler, Mickey Smith – is eventually sucked back into the Void due to the actions of the Tenth Doctor, but the specially-equipped cult members use an "emergency temporal shift" to escape that fate. They reappear in 1930 in New York where they try to use humans to create a new race of Daleks. While three members of the Cult of Skaro are killed, the fourth – Dalek Caan – escapes through another emergency temporal shift. It returns to the Time War and, at the cost of its sanity, rescues the Daleks' creator, Davros. Davros subsequently uses cells from his own body to create a new Dalek Empire and keeps Caan close at his side because of the latter's prophetic abilities. The Daleks attempt to destroy all reality with a 'Reality Bomb' powered by 27 stolen Worlds, leaving themselves the only creatures. However, Caan manipulated Davros to help the Doctor and Donna Noble defeat the Daleks after seeing the damage the Daleks had caused throughout time. The Daleks are destroyed by a clone of the Tenth Doctor, while Davros and Caan are left behind on the Dalek flagship as it is destroyed.
One ship containing three Daleks escaped that defeat after accidentally falling through time, where it then picked up a trace of a Progenitor device that contained pure Dalek DNA. However, because these Daleks had been created from the DNA of Davros, the Progenitor did not accept them as true "Daleks"; in order to restart the Progenitor, the Daleks trick the Eleventh Doctor into activating it for them during World War II. Once activated, the Progenitor device created a new "Paradigm" of Daleks that destroyed the previous Daleks and escaped through time, forming a new race of Daleks. Eventually learning of the Time Lords' survival alongside various other races during the events of The Time of the Doctor, the Daleks laid siege on the planet Trenzalore for centuries to either resume the Time War or kill the Doctor before he could release the Time Lords back into the universe. In the end, the Dalek fleet was wiped out by the Eleventh Doctor during the first phase of his regeneration.
Survival of the Master
After the Time War, the Doctor is convinced that he is the only surviving Time Lord, saying that he would know of any others if they had survived. The last words of the Face of Boe were "You are not alone". The cryptic statement is explained when the Doctor encounters a Professor Yana who is revealed to be the Master. The Master had been hiding in human form at the end of the universe using a Chameleon Arch, having escaped the destruction of both the Time Lords and the Daleks. By taking human form, he avoided detection by the Doctor, who was unaware of his nemesis' resurrection during the Time War in the first place. He recovers his memories and Time Lord nature after the Doctor re-triggers memories. He escapes in the Doctor's TARDIS to early-21st Century Earth and makes himself Prime Minister of Great Britain, going by the name Harold Saxon. He converts the TARDIS into a Paradox Machine, enabling an army of Future Humans who have turned into the Toclafane to invade Earth. However a year later the Paradox Machine is destroyed, erasing the Master's rule. The Master is resurrected in "The End of Time" by figures loyal to Harold Saxon, but the process goes wrong and he is trapped in a dying body that is burning up his life force, so although he is able to project electricity from his hands, he is left with an insatiable hunger, which leads him to drain the energy of several humans. He manages to copy himself onto the whole of humanity using alien technology, amplifying the sound of drums inside his head, and allowing the Time Lords trapped at the end of the Time War to escape the Time-Lock with Gallifrey, so it will materialise above the Earth. The Master then tries to copy himself onto the Time Lords as well, but this fails, and humanity is restored. Finally the Doctor breaks the connection between Earth and Gallifrey, and the Master saves the Doctor to avenge himself on the Time Lords, who he learns planted the sound of drums inside his head which drove him insane. The Master disappears along with Gallifrey, his fate unknown.
Impact on other species
The timelines of other races and planets shifted without the inhabitants of the worlds affected being aware of the changes in history, as they were a part of them. Most affected were the Greater Animus, which died; the Nestene consciousness and the Zygons, who lost their home worlds and attempted to conquer Earth for its resources; the Eternals, who apparently fled this reality in despair; and the Gelth, who lost their physical form and were reduced to gaseous beings, who attempted to possess human corpses in 1869 using a Time Rift in Cardiff. The Gelth described the war's impact as "invisible to lower species but devastating to higher forms", such as the Forest of Cheem, which was distraught at the bloodshed. It is also said to have destroyed the unnamed race that Eve originated from.
The Time War and continuity
The Time War provides a convenient in-story explanation for any contradictions in series continuity: for example, writer Paul Cornell has suggested that Earth's destruction by an expanding sun in The End of the World five billion years hence, as opposed to the original depiction of its demise around the year 10,000,000 AD in The Ark (1966), can be attributed to changes in history due to the War. Steven Moffat, writer and later executive producer for Doctor Who, has gone further, arguing that "a television series which embraces both the ideas of parallel universes and the concept of changing time can't have a continuity error—it's impossible for Doctor Who to get it wrong, because we can just say 'he changed time—it's a time ripple from the Time War'".
Time Wars in spin-off media
The Last Great Time War and previous time wars also feature in various Doctor Who spin-off media.
Gallifrey audio series
Gallifrey is the umbrella title of a series of audio plays by Big Finish Productions, set on Gallifrey during Romana's tenure as President. In Gallifrey: Panacea, the final chapter of the third series, the Time Lord Irving Braxiatel speaks of "rumours out there in the big wide universe—more than rumours, in fact—that something's coming to Gallifrey, something worse than you could possibly imagine." Because of these rumours, Braxiatel engineers the removal of the Time Lord biodata archive from Gallifrey, in order that the Time Lords might someday be restored after their planet meets its doom. Former Big Finish producer Gary Russell indicated in a forum posting on Outpost Gallifrey that this was a reference to the television series' Time War.
The Sixth and final series of Gallifrey, will feature the Daleks invading Gallifrey.
The later Companion Chronicles audio story, The Catalyst, implies that Leela survived the Time War; she mentions that her adopted homeworld no longer exists and she ages rapidly due to the Time Lords no longer being able to keep her young.
Eighth Doctor Adventures
In a story arc stretching through several of the Eighth Doctor Adventures, sometime in the Doctor's future, a war is fought between the Time Lords and an unnamed Enemy, the Eighth Doctor becoming involved in the events of the war during the events of Alien Bodies, when he unintentionally becomes involved in an auction for the body of his future self due to his biodata codes being the only means of accessing dangerous Time Lord secrets, and The Taking of Planet 5, where he must stop a group of future Time Lords from releasing the monstrous Fendahl in an attempt to use it as a weapon. In this story arc, Gallifrey is also destroyed as a result of the Eighth Doctor attempting to prevent the war from beginning as the Enemy begin their first assault in- having learned that he unintentionally provoked the War-, believing that it would be better for the Time Lords to die now rather than experience a war that would dehumanise them to the point of becoming monsters which all evidence suggests they could not win (The Ancestor Cell, 2000). This cataclysm also creates an event horizon in time that prevents anyone from entering Gallifrey's relative past or travelling from it to the present or future. The last Eighth Doctor Adventures novel, The Gallifrey Chronicles, establishes that the Doctor has the ability to restore the planet and its inhabitants, having downloaded the contents of the Matrix into his subconscious mind in the minutes before Gallifrey's destruction, albeit at the cost of his own memories. The novel ends without revealing if he does indeed do this.
Russell T Davies, executive producer of the series, commented that there is no connection between the War of the books and the Time War of the television series, comparing Gallifrey being destroyed twice with Earth's two World Wars. He also said that he was "usually happy for old and new fans to invent the Complete History of the Doctor in their heads, completely free of the production team's hot and heavy hands".
Despite this unequivocal statement, writer Lance Parkin speculated in an essay that the two destructions of Gallifrey may be the same event seen from two different perspectives, with the Eighth Doctor present twice (and both times responsible for the planet's destruction). This is supported due to the novels' destruction of Gallifrey involving an evil future version of the Eighth Doctor as the leader of the invading force, with the events leading to Gallifrey's destruction being triggered by the Doctor's attempt to prevent that future from coming to pass.
Doctor Who comic strip
In three comic strip stories written by Alan Moore in 1979, the Time Lords, assisted by The Special Executive, fight a time war early in their history against the "Order of the Black Sun", based some thirty thousand years in their future. The first strike of the war, from the Time Lords' point of view, is when a Black Sun agent travels back in time, and attacks the Time Lords just as they are about to turn the star Qqaba into a power source for their time experiments. This also causes the apparent demise of the stellar engineer Omega. The Time Lords do not know why the Black Sun (whom they had never encountered before the attack) should have wanted to strike at them, and surmise that it was for something they had yet to do. Years later, at a diplomatic conference, a representative of the Order is murdered by the Sontarans, and the murder is blamed on the Time Lords. This provides the motivation for the war's beginnings, as from the Order's point of view, the Time Lords are the ones who strike first.
Doctor Who Adventures
In this comic book series an insectoid race called the Skrawn appeared, whose planet Kolox the Doctor claims was destroyed in the Time War.
In the IDW comic miniseries The Forgotten, the Tenth Doctor recounts to Martha Jones a story from the Eighth Doctor's participation in the Time War. The Eighth Doctor was imprisoned by a race of robots for several weeks on a planet in the middle of the war, before teaming up with a Malmooth fellow prisoner and faking his death in order to escape. It is revealed his capture was staged by him so that he could acquire the Great Key he needed to arm a modified De-Mat Gun that could be used to seal the Medusa Cascade. The Tenth Doctor further implies that the Eighth Doctor died, alone and companionless, at the end of the Time War.
The Sarah Jane Adventures
In the episode The Mad Woman in the Attic Eve speaks about the Time War, stating that her people could see timelines and this made them a target and they were exterminated.
Engines of War
In July 2014, the BBC released the novel Engines of War by George Mann, which features the War Doctor in a novel set in the Time War itself. During the novel, the War Doctor and his new companion Cinder- a human resistance fighter on the Dalek-occupied world of Moldox- discover that the Daleks intend to use the temporal anomalies of the Tantalus Eye, a rift in time in the Moldox system, to develop a weapon that could completely erase Gallifrey and the Time Lords from history, with Rassilon's plan to stop the Dalek plot involving the destruction of the Eye and all inhabited planets around it. Refusing to accept this, the Doctor is able to sabotage Rassilon's plan and use the energy of the Tantalus Eye to erase the Daleks' scheme, but the actions of a Time Lord agent result in Cinder's death, leaving the War Doctor resolved to end the war once and for all as he recognizes how far his people have fallen in the name of victory.
