Dalek Wars

The "Dalek Wars" were the series of conflicts that involved forces of the universe, primarily humans, battling the Daleks.

Thal-Dalek War
The first war to involve the Daleks was the Thousand Year War fought on Skaro. Davros unleashed the newly-created Daleks into the Thal Dome at the wars' end. (TV: Genesis of the Daleks) Over the centuries, the Thals and the Daleks remained largely isolated from each other until one Thal tribe ventured into the petrified jungle, near the Dalek City, in search of food. The Daleks attempted to wipe the Thals out by bombarding Skaro's surface with radiation, on which the Daleks had become dependent. However, with the help of the First Doctor and his companions, the Thals raided the Dalek City and severed their power supply. (TV: The Daleks)

Fifty cycles later, surviving Daleks attacked the new Thal City but, once again with the First Doctor's assistance, the Thals drove them back. The Dalek City was largely devastated, although the Thals resolved to remain alert to any other potential Dalek settlements elsewhere on Skaro. (AUDIO: Return to Skaro)

The Thals later remembered this period as "the Dalek war", which Vaber recalled took place generations prior to 2540. (TV: Planet of the Daleks) It was also known to them as the "First Dalek War". (PROSE: Doctor Who and the Planet of the Daleks) The Thals' wars against the Daleks continued for many centuries after this period. (PROSE: War of the Daleks, The Evil of the Daleks)

First Dalek War
The first full-scale conflict between the Daleks and humanity was the Dalek invasion of Earth during the 22nd century, also known to the latter as the First Dalek War. (PROSE: Prelude Deceit) The war resulted from various Dalek encounters with human culture as the fledgling Dalek Empire expanded. The Dalek Emperor declared human characteristics a dangerous incompatibility with the Dalek way of life and began mobilising the Empire for "all-out war on all human beings... everywhere." (COMIC: Shadow of Humanity, The Emissaries of Jevo)

After the emergency landing of the Earth ship, the Starmaker, on Skaro, the Daleks discovered the coordinates of Earth. (COMIC: The Road to Conflict) Although the Dalek Fleet was initially repelled after first venturing into the solar system, (COMIC: Return of the Elders) the Daleks returned after bombarding the Earth with meteorites and began a ten-year occupation of the planet and others in the star system in 2157. Seeking to transform the planet into a massive spaceship, the whole invasion fleet was blown apart in the explosion which resulted from their bomb being jammed in place below their base. (TV: The Dalek Invasion of Earth)

In the 2180s, the Dalek Time Controller led a second invasion, but it was ultimately halted by the interference of the Eighth Doctor. (AUDIO: Lucie Miller, To the Death)

The Daleks remained bitter about the failed conquest of the Earth, and even identified the Doctor as an enemy responsible for their defeat. (TV: The Chase)

Second Dalek War
In 2520, the brief but destructive Human-Draconian War broke out as the Earth Empire and Draconian Empire. (TV: Frontier in Space) Although it did not involve the Daleks, it was used as the launch pad for their next invasion (AUDIO: The Dalek Conquests) and it formed part of the numerous wars of the period. (PROSE: The Chase)

In 2540, with the aid of the Master and the Ogrons, the Daleks attempted to drive the two empires into another war, planning to invade in the aftermath. The Third Doctor exposed the deception and the humans and Draconians united to face a common enemy. (TV: Frontier in Space) With Time Lord intervention, the Doctor was diverted to Spiridon to delay the awakening of the Dalek Army with the aid of the Thals. However, the Dalek Supreme considered the setback a delay, not a defeat. (TV: Planet of the Daleks)

Eventually, the Second Dalek War began. After the First Dalek Incursion, which destroyed many planets, the the war lasted around another forty years. (PROSE: Prisoner of the Daleks) During the period, refugees fleeing the Dalek Wars were resettled on planets such as Axista Four, although one stated date indicated this took place in 2539, one year before the Second Dalek War began, unless different dating systems were used. (PROSE: The Colony of Lies)

Towards its end, the Daleks sought to exploit the Arkheon Threshold to change human history. The Tenth Doctor and a team of bounty hunters led by Jon Bowman destroyed the flagship of Dalek X, the Dalek Inquisitor General, and Earth forces attacked the Dalek base on Arkheon, after which the Doctor closed the rift. The Supreme Dalek's war machine was thrown into chaos, leading to the end of the war. (PROSE: Prisoner of the Daleks)

Third Dalek War
The Third Dalek War broke out in the same period as its predecessor and the Human-Draconian war. It supposedly occurred prior to Steven Taylor's native time period, although this was in itself an inconsistent marker. (PROSE: The Chase)

During the war, the Lucifer star system was of paramount strategic importance but it was denied to both sides (PROSE: Lucifer Rising) the Daleks launched plague missiles at the Outer Worlds of the Earth Empire, sparking a devastating outbreak of space plague. In response, Earth forces travelled to Exxilon to acquire the only known cure, parrinium. The Daleks followed them to prevent this leading to the Exxilon Gambit. (PROSE: The Secret Lives of Monsters)

On Exxilon, the Marine Space Corps and the Daleks were stranded by the Great City of the Exxilons and agreed on a temporary truce. After the city was brought down, the Daleks left the planet with the mineral. However, their supplies had been replaced by bags of sand and the ship was blow up by Dan Galloway, who stowed away on board. The human survivors returned the parrinium to the Outer Worlds, saving millions of lives. The father of Peter Hamilton, one of the Marines on the mission, had been a casualty of "the last Dalek war." (TV: Death to the Daleks)

The Exxilon Gambit marked the last act of the Third Dalek War. (PROSE: The Secret Lives of Monsters) The high casualty rate among the Earth Empire, compounded with those suffered in the previous Dalek Wars of the period, put a stop to Earth's expansionist era. (PROSE: The Chase) A highly fictionalised account of the war served as the premise for the low-budget holovid series EarthDoom XV. (PROSE: Sky Pirates!)

Great War
During the 36th century, the Daleks disappeared from human space and pursued conflicts elsewhere. (TV: Mission to the Unknown) In the 40th century, they returned and attacked some human targets (AUDIO: The Destroyers) but these incursions remained top secret. (TV: The Daleks' Master Plan, AUDIO: The Guardian of the Solar System) The Space Security Service became involved in other conflicts, with species like the Sontarans. (AUDIO: The Sontarans) A non-aggression pact was signed in 3975, (TV: The Daleks' Master Plan) but in 3984, the Seventh Doctor told Bernice Summerfield that a "massive Dalek war" was to start in "about thirty years time". (PROSE: Legacy)

In 3999, Mavic Chen, the Guardian of the Solar System, secretly struck a deal with the Daleks in a bid to defend Earth's influence. (AUDIO: The Guardian of the Solar System) The Daleks amassed the Great Alliance, planning a huge assault on the solar system using a time-manipulating doomsday weapon, the Time Destructor. Chen sought to usurp the weapon for himself and turn on the Daleks, but he became power-mad and was eventually killed by the Daleks. The First Doctor was able to steal the Time Destructor and turned it against the Daleks, wiping out the invasion force on Kembel. (TV: The Daleks' Master Plan)

When the plans were discovered by Earth forces, (PROSE: The Mutation of Time) the Great War began against the Daleks. Humanity, the Thals, the Draconians and the Terran Federation all became involved in the millennium-long conflict. (PROSE: The Evil of the Daleks) The war resulted in the Galactic Federation being torn apart and forced to re-evaluate itself in the aftermath. As the planet Peladon was not a member of the Federation, they avoided Dalek attack. (PROSE: Legacy)

Eventually, facing total defeat, (PROSE: The Evil of the Daleks) the Dalek Emperor devised a plan to infect humanity with the Dalek factor, turning them mentally into obedient Daleks. The Second Doctor was blackmailed into aiding with the operation (TV: The Evil of the Daleks)

After the Last Great Time War from the Daleks' perspective, they engaged in another war between humans during the 40th century, battling the SSS. It raged for a hundred years, into the 41st century, (COMIC: The Only Good Dalek) overlapping with the original start of the Great War. (TV: The Daleks' Master Plan, PROSE: The Evil of the Daleks)

In an alternate timeline in which the Doctor never interfered with the Kembel operations, the Daleks developed the Time Destructor and embarked an uncontested series of conquests. The campaign ended with the attack on Urbinia, after which the timeline was averted by the Second Doctor. (AUDIO: Daughter of the Gods)

Human perspective of the Last Great Time War
From the perspective of humanity, the Daleks suddenly disappeared from time and space after the Tenth Dalek Occupation, (PROSE: A Brief History of Time Lords) during which the Daleks were "the greatest threat in the universe," as recalled by Jack Harkness, a former Time Agent from the 51st century. The Occupation occurred "thousands of years" prior to the Battle of the Game Station in 200,100. As the Ninth Doctor recalled, they had left to fight the Last Great Time War against the Time Lords. (TV: The Parting of the Ways)

Groups of humans became involved in the Time War after the Daleks occupied the Tantalus Spiral, and invaded the planet Moldox. They were aware the war had lasted, from a linear perspective at least, around 400 years. Towards the war's end, the War Doctor erased the Dalek occupation through massive time manipulation. The humans involved all lost their memories of the war, although the Doctor claimed these memories would eventually resurface. In honour of one of them, Cinder, the Doctor vowed to end the war. (PROSE: Engines of War)

According to the Gelth ambassador, the Time War was devastating to "higher forms" but invisible to "smaller species". (TV: The Unquiet Dead) Jack Harkness originally believed the Time War was just a legend. (TV: The Parting of the Ways)

Other Dalek wars
A war was fought between the Daleks and humanity in which the latter led the Combined Galactic Resistance. (TV: Into the Dalek)

The Daleks engaged in a war against the robot Movellans, leading to a stalemate, (TV: Destiny of the Daleks) until the Movellans released the Movellan virus, (TV: Resurrection of the Daleks) an act of biological warfare which devastated the Dalek Empire. The resulting factionalism led to the civil war between the Imperial and Renegade factions, (PROSE: Remembrance of the Daleks) although according to the Dalek Prime, the Movellan War was a staged hoax. (PROSE: War of the Daleks)

Daleks which were engaged in a conflict against humanity travelled back through Earth's history where they conducted the Dalek Project to understand how humans fought. After arriving in the period of the First World War, they were defeated on the Western Front in 1917. The survivors were defeated in 2017. (COMIC: The Dalek Project)

Final Dalek War and beyond
The Final Dalek War was a hypothesised future conflict, supposedly sparked by "the penultimate destruction of Skaro". (PROSE: The Infinity Doctors)

By the far future, circa 10,000,000, the Daleks were considered a part of the First Segment of Time. (TV: The Ark)

According to the Daleks themselves, the "creatures" of 500,000,000 knew nothing of them. (PROSE: I Am a Dalek)

Remembrance
A Velyshaan museum contained an exhibit on the wars after the Second Great Dalek Occupation. (PROSE: Museum Peace)

By the time of humanity's war against the Wall of Noise, the Great War against the Daleks to be ancient history. (AUDIO: The Anachronauts)

Behind the scenes

 * According to Lance Parkin's Whoniverse: An Unofficial Planet-By-Planet Guide to the Universe of the Doctor, from Gallifrey to Skaro, the script for Into the Dalek specifies that the story takes place in the 31st century.
 * According to A History of the Universe and aHistory, the events of Death to the Daleks (the Exxilon Gambit of the Third Dalek War) took place in 2600. Likewise, The Dalek Handbook dates the conflict as taking place in the 27th century. This is reasonably consistent with the known dates of the Second Dalek War.
 * In a cut scene from Lance Parkin's earlier novel The Dying Days, the 42nd Doctor described the events of the Final Dalek War to Jason Kane and Iphegenia. During the Final Dalek War, the Children of Kasterborous teamed up with humanity to fight the Daleks in their own territory. Tens of trillions died, and entire galaxies were destroyed, but after countless years of fighting the Daleks were driven to extinction. In their wake, the people of the universe were left united in universal peace.
 * Doctor Who: Battles in Time magazine regularly featured double-page spreads of various Dalek conflicts in a series entitled Dalek Wars. Each bi-weekly instalment was accompanied by a short source dealing the events.
 * According to #55, a conflict known as the Third Dalek War was fought between the Daleks and the Second Great and Bountiful Human Empire. According to the source, the retreating Daleks attack the planet JT227, the source of the element Promethium 62, utilised by humans are using to break Dalek forcefields. The human' Spindroid mining machines fight back and overpower the Daleks, which are subsequently pushed out of human space. As this involved the Second Great and Bountiful Human Empire and not the Earth Empire, it is at odds with in-universe mentions of the Third Dalek War.
