Great Britain was one of the British Isles.
Great Britain was first united as one nation in 1707, by events set in motion through the Alien Act of 1705. (TV: The Highlanders) Its capital city was London, with Edinburgh and Cardiff serving as the regional capitals of Scotland and Wales respectively. (TV: The War Machines, The Highlanders, The Unquiet Dead) Britain shared its eastern coast with the North Sea. (TV: The Lie of the Land)
The Doctor's long association with the country led them to often be identified as British, typically when they were visiting other parts of Earth. (TV: The Gunfighters, Doctor Who, Demons of the Punjab)
Influence on the Doctor Edit
The Doctor visited Great Britain more than anywhere else on their travels. He developed a great affinity for it and even lived there for some time. (TV: "An Unearthly Child", et al.) The Doctor was well acquainted with the island's historical figures, and was a friend, an antagonist, and even a lover to several of her monarchs. (TV: Voyage of the Damned, The Crusade, Tooth and Claw, The Impossible Astronaut, The Day of the Doctor, The Shakespeare Code, The Beast Below) In 1562, when the Tenth Doctor married Queen Elizabeth I, he was effectively King of England. (TV: The Day of the Doctor) The Doctor sometimes considered themselves to be British and would often refer to themselves as such, (TV: Doctor Who, PROSE: History 101, et al.) though on one occasion the Tenth Doctor said he wasn't English. (TV: The Day of the Doctor) He accepted a British knighthood from Queen Victoria, (TV: Tooth and Claw) and, in his fifth incarnation, an English knighthood from an imposter posing as King John. (TV: The King's Demons)
After several failed attempts, the Roman Empire succeeded in conquering Britain in 43. The Roman occupation of the island lasted until the early 5th century. (AUDIO: The Wrath of the Iceni) One of these failed attempts was led by Julius Caesar in 55 BC. (AUDIO: Living History)
In the 29th century, due to solar flares, the United Kingdom abandoned Earth for Starship UK; Scotland opted for its own starship separate from the rest of the kingdom. (TV: The Beast Below) This continued until at least the 52nd century. (TV: The Pandorica Opens)
