Ecgberht I of Northumbria
Historians presume that Ecgberht ruled as the Great Army's tax collector and that he belonged to one of the several competing royal families in Northumbria.
The next report of Ecgberht is in 872: "The Northumbrians expelled their king Egbert, and their Archbishop Wulfhere". Finally, Ecgberht's death is reported in 873, and it is said that Ricsige succeeded him.
