Earl of Northumbria is a title in the Anglo-Danish, late Anglo-Saxon, and early Anglo-Norman period sin England. The earldom of Northumbria was the successor of the ealdormanry of Bamburgh, itself the successor of an independent Bernicia. Under the Norse kingdom of Jorvik, there were earls of Deira. Eventually all Northumbria was united under the Bernician dynasty. This dynasty held onto Bernicia until 1041, but from 1016 there were other earls in Jorvik who were appointed by Canute the Great over all Northumbria. It was itself broken up in the early Norman period and dissolved into the earldoms of York and Northumberland, with much land going to the prince-bishopric of Durham.
