Deira

Deira (Old English: Derenrice or Dere) was a kingdom (559–664 AD) in Northern England that probably emerged when Anglian warriors conquered the Derwent Valley in the third quarter of the fifth century. It extended from the Humber to the Tees, and from the sea to the western edge of the Vale of York. It later merged with the kingdom of Bernicia, its northern neighbour, to form the kingdom of Northumbria. Bede wrote of Deira in his Historia Ecclesiastica (completed in 731).
