British Empire

The British Empire was the name used by the United Kingdom during its time as a colonial power.

Josiah Samuel Smith hoped to take over the British Empire by having Redvers Fenn-Cooper assassinate Queen Victoria. (DW: Ghost Light)

Yvonne Hartman of Torchwood One hoped to use alien artefacts to rebuild the British Empire, much to the Doctor's confusion and displeasure. This plan was abandoned after the battle of Canary Wharf, nor was it recommenced even after Torchwood's resurrection. (DW: Army of Ghosts)

However, the British or English Empire monicker was also used to denominate several alternate variants of the United Kingdom; for the most part, these were usually more extreme versions of the British government, totalitarian states subject to xenophobia. One of these parallels was seen exploiting and torturing a crippled version of the Sixth Doctor (BFA: Jubilee) and another one was briefly created by Sabbath in which the Empire was murdering key personnel essential to the development of the computer. (EDA: The Domino Effect) These timelines, for obvious reasons, were seen by the Doctor as mockeries and were destroyed or the events leading to their creation undone.
