The 22nd century Dalek invasion, sometimes known as the First Dalek War (PROSE: Prelude Deceit) was a conflict between humanity and the Daleks, consisting of Dalek attacks on human colonies followed by a decade long occupation of Earth in the 2150s and 60s. (TV: The Dalek Invasion of Earth, etc.) To the Daleks, the invasion was a means for Project Degravitate. (PROSE: Doctor Who and the Dalek Invasion of Earth, AUDIO: The Dalek Conquests) Twenty years later, in the late 2180s, early 2190s, they reprised and updated their plan with the aid of the Dalek Time Controller, a Dalek from the future. (AUDIO: Lucie Miller / To the Death) According to some other accounts, the Dalek invasion took place in the 21st century. (TV: Genesis of the Daleks, PROSE: Doctor Who and the Crusaders)



In 1903, after receiving a wealth of information from the future, Grigori Rasputin foresaw, among other things, the First Doctor, Ian Chesterton, Barbara Wright and Susan Foreman battling "strange beings" who had invaded Earth in the future. (AUDIO: The Wanderer)


According to one account, the early Daleks knew of the existence of other planets even though a lack of space travel confined them to Skaro. When Kest, a Krattorian slave trader, landed on the planet, the Daleks were able to acquire from him the plans to create their own spacecrafts. (COMIC: Power Play) Going with a flying saucer design, the Daleks invaded Alvega, (COMIC: The Amaryll Challenge) Solturis, (COMIC: The Penta Ray Factor) and Phryne, (COMIC: The Archives of Phryne) with plans for other planets such as Oric. (COMIC: Eve of War) According to another account, the Daleks first learned about life existing on other worlds due to the First Doctor's visit to Skaro. (AUDIO: The Lights of Skaro)

The existence of Earth, however, managed to elude the Daleks for a time, the planet long being their blind spot. (COMIC: Legacy of Yesteryear, The Road to Conflict) Nevertheless, they did know of the existence of humans and tensions began to rise. In one instance, a Dalek created with human-like quailities seized control from the Dalek Emperor and began to teach the Daleks that beauty was a strength. To solve the problem, the Emperor likened the strength of beauty to flowers, which withered and died. Beauty therefore did not last which meant it could not be a source of strength and was for human beings. The Emperor had the rebel Dalek destroyed and issued a new Dalek order, stating that humans were to be destroyed. (COMIC: Shadow of Humanity) The Daleks also faced what they called the human spirit in the humanoid species from the planet Jevo. Although they were destroyed, the Emperor wondered how the Daleks would fare against such a resilient spirit in "the all-out war on all human beings... everywhere." (COMIC: The Emissaries of Jevo)

Humanity remained unaware the Daleks were plotting against them. By the late 21st century, humans had experienced the Break-out and possessed a number of colonies beyond Earth. (PROSE: Prelude Deceit) Years prior to the invasion, (PROSE: The Power of the Daleks) the human colonists on Vulcan were threatened by a smaller-scale Dalek attack. (TV: The Power of the Daleks) However, by 2136, both Vulcan and the Daleks were considered little more than legends. (PROSE: The Murder Game)

An Earth-made ship, the Starmaker, was pounded by a meteor storm and forced to land on Skaro. The Daleks destroyed the ship. The only survivors were Captain Flint Fleet and two children, siblings Tom and Jennie, who escaped in a Dalek saucer to warn Earth of the danger posed by the Daleks. Among the wreckage of the Starmaker, the Daleks found the remains of a piece of paper which revealed to them the existence and location of Earth. The Emperor declared that the Daleks would search for Earth and conquer it. (COMIC: The Road to Conflict) When the Daleks first ventured into the Sol System, their fleet was initially repelled by Earth forces led by Commander Trent with the help of the Elders. The Emperor, the Black Dalek and the Red Dalek escaped and resolved to return. (COMIC: Return of the Elders)

Colony attacks[]

The Dalek Emperor on Skaro formulated the plan for the invasion of Earth and its subsequent transformation into a planet-sized spaceship, choosing Bedfordshire as the area for the primary mining operations meant to drill into the Earth's core and replace it with an interstellar engine. Once the plan was complete, he gave the order to begin the invasion of Earth. (AUDIO: The Mutant Phase)

The invasion began in 2157 with mysterious attacks on Sifranos in the Arcturus sector (a moon of Sifranos was destroyed, one billion settlers being massacred), Azure, Qartopholos, (PROSE: Lucifer Rising) and Mars. (TV: Genesis of the Daleks) These were followed by the plague attacks directly on Earth while the Dalek Fleet massed near Epsilon Eridani. With the colonies destroyed, Earth could expect no assistance from them when the Daleks invaded Earth in 2158. (PROSE: Lucifer Rising) The Daleks operated a blockade of the Solar system to prevent Earth's colonies from attempting to liberate their homeworld. The colonies experienced many problems from the occupation, as they were dependent, to a degree, on communication with and support from Earth. (PROSE: GodEngine, Lucifer Rising) Later in 2157, the Daleks attempted to invade Mars. However, the inhabitants developed a genetically engineered virus that attacked their spacecrafts wiring, meaning that this invasion attempt had failed. (TV: Genesis of the Daleks, PROSE: GodEngine)

Earth's invasion[]

The first incident of the invasion came in 2157, (PROSE: Lucifer Rising) when Earth was bombarded with meteorites. At first this was thought the result of a cosmic storm, but shortly after things had returned to normal, people started dying of a new plague sent by the Daleks via the meteorites. The majority of the population of Africa, Asia and South America died before humans could find a cure. (TV: The Dalek Invasion of Earth)

Some humans were immune to the plague, because the Seventh Doctor had given to Piper O'Rourke a counter-virus that conferred immunity to make sure that there would be humans left to help his first incarnation defeat the invasion. (PROSE: Lucifer Rising)

The Terran Security Forces were easily defeated by the Daleks. (PROSE: The Final Sanction)

Iris Wildthyme visited Putney Common during the invasion. A Dalek saucer landed on the Common, Iris and her friends were among the first to throw homemade bombs at it. (PROSE: From Wildthyme with Love)

The Twelfth Doctor and Clara Oswald wound up during the events of the invasion after they jumped into a portal created by a Time fly at the hands of Ethel. They were chased by time flies and Daleks alike but were able to explode them using a bomb his first incarnation had previously disarmed. (COMIC: A Stitch in Time)

At some point, New York City was completely destroyed. London, on the other hand, though one of the locations where the Daleks landed, was merely occupied and remained relatively intact (TV: The Dalek Invasion of Earth) although the city suffered some of the worst attacks since the Blitz and the 1944 V1 and V2 attacks by the Nazis during World War II, with the Daleks reducing many areas to gravel. (PROSE: Illegal Alien) Some areas of the city became infested with wolves, with a "danger zone" being identified wherein it was unsafe to live. (PROSE: When the Wolves Came) St Paul's Cathedral survived the invasion as well as the first four world wars. (AUDIO: Frostfire)

The Daleks held the Earth for about ten years. During the occupation period, small groups of human resistance fighters continued to exist. (TV: The Dalek Invasion of Earth)

The Sixth Doctor and Peri Brown landed in 2163. The Daleks were unfamiliar with the Doctor, thinking he was a human. The Doctor was interrogated by a Black Dalek. He foiled the Daleks' plan to unleash a Varga plant virus. The Doctor and Peri also defeated the Roboman Elite and erased any record of his involvement afterwards but the invasion continued to ensure the First Doctor finally put an end to it. (AUDIO: Masters of Earth)

The Daleks commenced a mining operation in Bedfordshire in order to reach the Earth's magnetic core, replace it with a propulsion system, and turn the whole planet into a massive spacecraft to conquer the galaxy. (TV: The Dalek Invasion of Earth)


In 2167, (AUDIO: The Mutant Phase) the First Doctor and his companions arrived in occupied London. Shortly afterward, the Daleks announced that they would destroy London. A freedom fighter named Dortmun, who had been developing explosives, initiated an attack on the Daleks' saucer at the London helipad. Although the attack liberated several prisoners of the Daleks, the bombs did not work effectively against the Daleks, leading to several casualties. Ian Chesterton, who had accompanied the freedom fighters, remained on the saucer as it travelled to Bedfordshire.

Following the saucer attack, the Dalek Supreme Command issued an order for the destruction of what remained of London using firebombs. One of these firebombs was placed near one of the resistance base entrances, which the Doctor, Susan and David Campbell were hiding beside. David spotted the bomb soon after, and was able to disable it by using acid from Dortmum's bombs to burn through the casing and remove the internal mechanism of the firebomb.

Some of the resistance fighters, including the Doctor, Susan and David, from London to the site of the Daleks' mining operation at Bedfordshire. Barbara Wright and Jenny also (independently) made their way towards Bedfordshire, but were captured. They all, however, assisted in the final destruction of the centre of Dalek operations on Earth. In the aftermath, the Daleks withdrew from the planet. Susan decided to remain in this time period with David. (TV: The Dalek Invasion of Earth)

Iris Wildthyme once claimed she had ended the invasion with her companion Jeremy. (PROSE: The Scarlet Empress)

Aftermath of the first invasion[]

One Dalek survived the invasion and bargained with former collaborator Marcus Bray to deliver it to a Dalek flying saucer so it could escape only for him to publicly execute it to win favour with the humans. Bray then led a witch hunt against Susan Foreman only for her and her allies to trick him into revealing his working for the Daleks. Following Bray's death, Susan set the saucer to self-destruct. On a broad scale, it was estimated that the invasion had sent Earth's technological development back 200 years. (AUDIO: After the Daleks)

The invasion killed about two-thirds of Earth's population. The Moonbase was cut off from the planet and the moon colonists were trapped on the satellite. About twenty years later the liberation, humans had grown xenophobic about aliens, rejecting Dalek technology in public burnings and regressing the level of the planet's technology by about two centuries. An Earth Council was in charge, handling the reconstruction. (AUDIO: An Earthly Child)

In 2169, Homunculette and Marie visited the ruins of the House of Commons to buy the Relic from the Black Man, who was selling remnants from the Toy Store. (PROSE: Alien Bodies)

P.J. Ring became a Revelator and later a saint after being exposed to the Source during the end of the invasion. (PROSE: A Star's View of Caroline)

During the invasion, humans dumped a lot of their dead into the River Thames, leaving the corpses as food for the blackwater parasites. Two years after the end of the invasion, the river was still filled with chemical sludge (PROSE: Alien Bodies) and sticky red algae that the Invaders fed to their aquatic pets. Even decades later, the Thames was still completely abandoned. (PROSE: A Star's View of Caroline)

Survival became increasingly difficult due to wild animals roaming the streets. Simon encountered a pack of wolves on the streets when scavenging for food, but survived by finding the TARDIS and using its telepathic circuits to seek help from the Twelfth Doctor and Clara. (PROSE: When the Wolves Came)


In the late 2180s, the Dalek Time Controller organised a second invasion of the planet. The Daleks were helped by the Time Lord known as the Monk, who brought on Earth a plague that killed and affected a number of people. The Monk was promised to be allowed to plunder the art treasures of the planet in return for his technical expertise. The Monk made three major contributions to the invasion; firstly, he repaired the Dalek Time Controller when it was blasted back through the Time Vortex, and was in a state of decay beyond the Daleks ability to repair. Secondly, the Monk was personally responsible for unleashing a virus into Earth's atmosphere which was beyond the humans' ability to stop it, killing millions and weakening the planet ready for the upcoming invasion. Lastly, the Monk provided the resistance with the technical ability to hack into Dalek transmissions during a final attempt to end the invasion, but he betrayed them to the Daleks.

The master plan was to pilot the Earth with a time warp engine, which would have become a plague planet teeming with the Amethyst viruses, through time and space, infecting entire planets. The invasion was stopped by the Eighth Doctor, thanks to the sacrifice of Lucie Miller and Alex Campbell. (AUDIO: Lucie Miller / To the Death)


The events of this invasion were recounted in the book, The Rise and Fall of Earth's Empire, by Layten Halkovich. (PROSE: The Secret Lives of Monsters)

News of the Daleks' repulsion from Earth quickly spread across the Dalek Empire, leading other subjected races to rise up against the Daleks. (PROSE: Dalek: The Astounding Untold History of the Greatest Enemies of the Universe)

The Daleks eventually identified the First Doctor and his companions and discovered their key role in "delay[ing]" the conquest of Earth. A squad of Daleks embarked from Skaro in a time machine on a mission to assassinate them. (TV: The Chase)

Forced by Davros to reveal to him the Daleks' future defeats, the Fourth Doctor recounted an invasion of Earth, possibly an inaccurate version of these events. He stated that the invasion occurred in the year 2000 and that the magnetic properties of Earth's core itself helped to defeat the Daleks, as well as the determination of human resistance fighters. (TV: Genesis of the Daleks)

In 2199, a Dalek research facility, DA-17, remained intact. The Eighth Doctor and his granddaughter Susan were trapped along with the Master and new Daleks were produced by the hatchery. They attempted to conquer England but were destroyed when DA-17 exploded. (PROSE: Legacy of the Daleks)

Following the second invasion, Susan made her home in a block of flats which had once been Coal Hill School. Despite the Doctor's efforts to distract her, Susan found that she had been sent Hypercube messages from the Time Lords, whom were engaged in a time war against the Daleks. Citing her participation in the resistance against the two Dalek invasions on Earth as well as reasoning that the Daleks would ultimately return should the Time Lords fall, Susan decided to accept their request and join the war despite the Doctor's protest, summoning a TARDIS to collect her. (AUDIO: All Hands on Deck)

By the beginning of the 23rd century, the invasion remained a source of much anxiety on Earth as governments tried to rebuild. With government approval, a powerful cartel of Earth conglomerates offered to rebuild and invest in the Terran Security Forces which grew into a huge army within five years. This army was used to combat the Selachians when their expanding power on the galactic market threatened that of Earth, and by 2204, they had all but destroyed the last outposts of the Selachian Empire. (PROSE: The Final Sanction)

Vicki Pallister learned about the invasion from the history books in her native time period of the 25th century. (TV: The Space Museum, The Chase)

By Steven Taylor's native time period, New York City had yet to be rebuilt in its entirety. (PROSE: Salvation; AUDIO: Return of the Rocket Men)

In the year 4000, when the Dalek Empire sought to strike from Kembel and destroy the Solar System, the First Doctor urged Bret Vyon to contact Earth and tell them to look into the invasion of 2157, hopeful that history would show them the way to defeat the Daleks again. (TV: The Daleks' Master Plan)

Alternate timelines[]

In a divergent timeline, a Dalek in Kansas in 2158, severely damaged by resistance forces, was stung by a parasitic wasp and implanted with eggs. The Daleks adjusted with a minor genetic change to counteract the eggs. Thousands of years later the genetic change resulted in the Mutant Phase, transforming the Daleks into nearly indestructible interstellar insects. The timeline was destroyed when the Fifth Doctor stopped the Dalek Emperor from implementing an ineffective pesticide. (AUDIO: The Mutant Phase)

In a timeline created in which the Decayed Master used a conceptual bomb to prevent the Doctor from leaving Gallifrey, the Dalek occupation was never repelled. (AUDIO: The Light at the End)

Behind the scenes[]

  • Masters of Earth dates the invasion between the years 2154 and 2164 (with the initial meteor bombardment occurring circa 2152) based on the calendar the Doctor and Ian find in The Dalek Invasion of Earth. Additionally, Ben remembers the Doctor mentioning the invasion of 2164 in the audio story The Forbidden Time. This is at odds with the dating in Lucifer Rising of the invasion in the ten years between 2157 and 2167, and with the title of the Peter Cushing version of the story, Daleks' Invasion Earth 2150 A.D., which evidently posited that the invasion took place in the year 2150 (although this latter source is not a valid source on this Wiki).
  • According to non-narrative material in DWBIT 1, six months after the initial incident, in 2158, the Daleks landed saucers on Earth. The Black Dalek led from the Command Saucer. One of these saucers attacked London. The British government put all their best defences into battle against the Daleks, sending the Air Force's helicopters and fighters to attack the Dalek ship. Tanks fought across the streets, and the Navy fought with gunboats. The humans were persistent, destroying many Daleks, but in a matter of days the Daleks subjugated the humans and converted the most intelligent into Robomen. It also stated that the Doctor’s involvement had led to the Daleks retreating.
  • As recounted by Susan Foreman in NOTVALID: Whatever Happened to Susan Foreman?, the invasion was waged by Daleks who had travelled back from the distant future using a TARDIS of their own. Having been defeated on Skaro by the Thals led by Ian Chesterton, their intent was to wreck revenge on Ian's people or, better still, prevent Ian himself from being born by going into the past. However, they were unable to go any further back than 2164 due to a leak in their fluid link.
