Following their victory the Vikings would initially set up a puppet king named Ecgberht, before later creating the Kingdom of Jórvík centred on York.

[8] In the spring of 867 Ælla and Osberht put aside their differences and united in an attempt to push the invaders out of Northumbria, leading to the battle of York on the 21 March.

[7] Norse tradition holds that the victorious Ivar and Ubba were brothers and that they captured Ælla and subsequently blood eagled him.

[12] In York, Viking leaders established a puppet king named Ecgberht,[13] who remained until 872, when a revolt drove him into exile in Mercia.

Halfdan Ragnarsson of the Vikings ended the revolt in 876 and directly occupied York and the rest of Deira (south-east Northumbria), partitioning it among his followers.

[15] Before the area was integrated into Wessex, the surviving Anglo-Saxon lords ruled Northumberland north of the river Tees from Bamburgh.
