Kingdom of Bernicia

Bernicia (Old English: Bernica rice, Beornica rice) was an Anglo-Saxon kingdom established by Anglian settlers of the 6th century in what is now southeastern Scotland and North East England.

The Anglian territory of Bernicia was approximately equivalent to the modern English counties of Northumberland, Tyne and Wear, and Durham, as well as the Scottish counties of Berwickshire and East Lothian, stretching from the Forth to the Tees. In the early 7th century, it merged with its southern neighbour, Deira, to form the kingdom of Northumbria, and its borders subsequently expanded considerably.
