England
England is one of the four constituent parts of the United Kingdom (along with Scotland, Northern Ireland and Wales). It appears to be the geographical region of Earth most frequently visited by the Doctor, who has adopted much of its customs, dress, and other cultural elements.
England constitutes the largest, most populous, and the most densely populated country of the United Kingdom. Because London, the capital of England (and the United Kingdom) is one of the largest, most populous, and wealthiest cities in Europe and indeed the world, England, especially the area immediately around London, has attracted the attention of many alien marauders in their bids to invade and conquer the planet.
