2150s Dalek invasion of Earth

One of the major events relating to Daleks and Humans was the 22nd century Dalek invasion of Earth.

History
The Daleks invaded Earth in 2157, first bombarding the planet with plague-bearing meteorites. The majority of the population of Africa, Asia and South America died before humans could find a cure, despite the fact that a counter-virus providing limited immunity had already been released into the population (DW: The Dalek Invasion of Earth, NA: Lucifer Rising). At some point, New York City also would also fall. (DW: The Chase)

After six months, the Daleks landed saucers with the command saucer led by a Black Dalek. The Daleks subjugated the humans and converted the most intelligent into cybernetically-controlled slaves known as Robomen. 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. (DW: The Dalek Invasion of Earth)

These events would cause difficulties for human colonists, who were dependent, to a degree, on communication with and support from Earth. (NA: Lucifer Rising)

Throughout this period the Daleks operated a blockade of the Solar system in order to prevent Earth's colonies from attempting to liberate their homeworld. (NA: GodEngine)


 * The invasion possibly ocurred during an earlier period of Dalek history as the Daleks, at that point had receiver dishes built into their casings to receive broadcast power for their survival. Earlier Daleks had had to rely on static electricity in the floors of the Dalek City.

In the late 2160s, most probably 2167, definitely after 2164, the Doctor, his companions and resistance fighters based in London (who included David Campbell) were able to sabotage the Dalek mine workings and destroy the centre of Dalek operations on Earth. In the aftermath of this the Daleks withdrew from the planet. The Doctor's grand-daughter, Susan Foreman decided to remain in this time period with David. (DW: The Dalek Invasion of Earth).

Tortured by Davros to reveal to him the Daleks' past defeats, the Doctor recounted this invasion, with some inaccurate information, saying that the invasion happened in the year 2000 and that the magnetic properties of the Earth's core itself helped to defeat the Daleks, as well as the determination of human resistance fighters. (DW: Genesis of the Daleks.)


 * In a separate timeline, the Daleks also invaded Earth from the future after World War III, nuclear war involving many nations, which happened in the late 20th century. However, the temporal paradox that enabled the nuclear war to occur was resolved and the timeline anulled. (DW: Day of the Daleks)

Behind the Scenes
The non-canonical film Daleks' Invasion Earth 2150 A.D gives a somewhat different account of these events.
