Part of the kingdom of Ebrauc, Deywr's original territorial boundaries are probably mirrored in the modern county boundaries of East Yorkshire, and it is likely that the region regarded Petuaria (modern Brough) as its local capital, until this lost its importance in the mid-fourth century, perhaps because the harbour had silted up. The main military post moved to Malton. From at least the early fifth century laeti were hired and settled locally in order to protect the north eastern shoreline of Britain.

The traditional pedigree of the Anglian royal family which later ruled the area suggests that these laeti settled on the coast under their own leaders on lands allotted to them by their British paymasters, and often within the structure of existing estates. In one version of the Anglian pedigree there is a note against the name of one Soemil to the effect that 'he first separated Deira from Bernicia'. A direct ancestor of Edwin (612-632), Soemil could have been a prominent figure among the Yorkshire laeti in the fifth century. It looks as if he was remembered for the leading part he played in making his people independent (at least nominally) from the regional British authority.

In 559 or 560, the long-lived king of Ebrauc died, and the Angles under their leader, Aelli, seem to have taken total control with very little Descent of the Kingdoms of Northern Britainfuss. In their  northern Teutonic tongue, they pronounced Deywr as Deira. They quickly overwhelmed Ebrauc.
