In Britain, a king called Vortigern (but note that ‘vortigern’ means ‘king’ in Brittonic, the ancient Britons’ language, so I worry someone might have got confused, but maybe there really was this King King) was beset by raids from the Picts, who came from what is now Scotland, and from the Scots from what is now Ireland. I know that sounds wilfully confusing but there’s nothing I can do about it.
