2150s Dalek invasion of Earth

The Daleks invaded Earth in 2157, first bombarding the planet with meteorites bearing plague. The whole populations of Africa, Asia and North America died before humans could find a cure.

After six months, the Daleks landed saucers with the command saucer led by a Black Dalek. The Daleks subdugated the humans and converted the most intelligent into controlled slaves knwon as Robomen. The Daleks commenced a mining operation in Bedfordshire in order to reach the Earth's magnetic core, replace the core, and turn the whole planet into a massive spacecraft.

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


 * 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, definately after 2164, the Doctor, his companions and resistance fighters centered out of London who included David Campbell. 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. The temporal paradox that enabled the nuclear war to occur, however, did get resolved and the timeline anulled. (DW: Day of the Daleks)
