Middle Ages

The Middle Ages were an era in human history following the Dark Ages.

At some point during the Middle Ages, the planet Strepto vanished. (TWN: Something in the Water)

Compared to the 21st century, Britain was on average three degrees colder in the Middle Ages. (K9TV: The Last Oak Tree)

Behind the scenes

 * The non-narrative source REF: Doctor Who: The Time Traveller's Almanac stated the Daleks had stolen Strepto, making it one of the twenty-seven planets they needed to activate the reality bomb. This is contradicted by DW: The Stolen Earth, which counts twenty-four planets being taken from 2009 and the other three from other eras named by the Tenth Doctor and Donna as the Lost Moon of Poosh, Pyrovillia and Adipose 3.
