Wales
Wales (Cymru)
Covering an area of 8000 square miles, Wales has 3 million inhabitants, 20% of whom can speak Cymraeg (Welsh).
Wales has been a principality of England since the Act of Union in 1536, although the "Welsh Assembly" sitting in Cardiff is elected by the Welsh people.
Not to be confused with Jimbo Wales, or with whales, which are both considerably smaller than Wales and not Celtic, as far as we know.
