Don't Worry, Nothing important here

[gaelic cowboy]

It is England whose intitutes were established by foreign conquerors, hauling it out of the Dark Ages. As can be testified to by the fact that the heart of England is not out in the middle of Yorkshire, but in London at the southwestern extremity, close to the continent from where Celts, Romans, Normans/French brought conquest, colonisation and culture.

To be fair whoever held Britain would have used London as the capital eventually there was a river useful for both defense and trade plus it was close to rich farmland further south and add in easy access to the North Sea and English Channel. The only other place suitable would be on the Severn but it faces the wrong way for trade from Europe, cities are rarely built purely for administration purposes and when they are they generally are pretty antiseptic.
