Northumbria - Ealdormanships and Earldoms in Northumbria (954–1217)

Ealdormanships and Earldoms in Northumbria (954–1217)

After the English regained the territory of the former kingdom, Scots invasions reduced Northumbria to an earldom stretching from the Humber to the Tweed. Northumbria was disputed between the emerging kingdoms of England and Scotland. The land north of the Tweed was finally ceded to Scotland in 1018 as a result of the battle of Carham. Yorkshire and Northumberland were first mentioned as separate in the Anglo-Saxon Chronicle in 1065.
