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, and continued to remain so even after Torchwood's resurrection. (DW: Army of Ghosts)

However, the British or English Empire moniker has also been used to denominate several alternate variants of the United Kingdom; for the most part, these are usually more extreme versions of the British government, exalting xenophobia and totalitarian states. 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, are seen by the Doctor as mockeries and are destroyed or the events leading to their creation are undone.
