Great Britain

Great Britain was the largest of the British Isles. It was governed by the United Kingdom. It consisted of England, Scotland and Wales.

Geography
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 it's eastern coast with the North Sea. (TV: The Lie of the Land)

Nationality
People from Great Britain were variously self-identified as "English", "Scottish" or "Welsh" — although members of any of these identities were also more generally considered "British" internationally. The Doctor's long association with the country led him to often be identified as British, typically when he was visiting other parts of Earth. (TV: The Gunfighters, Doctor Who)

Influence on the Doctor
The Doctor visited Great Britain more than anywhere else on his travels. He developed a great affinity for it and even lived there for some time. (TV: "An Unearthly Child", et al.) He was well acquainted with the island's historical figures, and was both a friend, and antagonist, to several of her monarchs. (TV: Voyage of the Damned, The Crusade, Tooth and Claw, The Impossible Astronaut, The Shakespeare Code) 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 himself to be British and would often refer to himself as such, (TV: Doctor Who, PROSE: History 101, et al) though on one occasion his tenth incarnation said he wasn't English. (TV: The Day of the Doctor) He accepted a British knighthood from Queen Victoria (TV: Tooth and Claw) and an English knighthood from an imposter posing as King John. (TV: The King's Demons)

History
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)
