Anglo-Saxon kingdom, Britain. Located in the eastern part of modern Yorkshire, it stretched from the River Humber to the River Tees. Its first recorded king, Aelle, reigned from AD 560. By the last quarter of the 7th century it had been united with its neighbour Bernicia to form the kingdom of Northumbria.

The name of the kingdom is of Brythonic origin, perhaps from Deifr, meaning "waters", or from Daru, meaning "oak", in which case it would mean "the people of the Derwent", a derivation also found in the Latin name for Malton, Derventio.
According to Simeon of Durham it extended from the Humber to the Tyne, but the land was waste north of the Tees. After the Kingdom of Ebrauc was annexed by Edwin, York (Ebrauc) became its capital. Before this it is likely that the capital would have been at or near Pocklington.
The first Anglian king of whom we have any record is Ælla, who flourished in the later 6th century after conquering the realm from the Britons in 581. After his death, Deira was subject to king Æthelfrith of Bernicia, who united the two kingdoms into Northumbria. Æthelfrith ruled until the accession of Ælla's son Edwin, in 616 or 617, who also ruled both kingdoms until 633.
