Angles settled in the area in the early 5th century. Cemeteries that are identifiably Anglian date from this period. Cremation cemeteries from the 6th century have been excavated close to York on The Mount and at Heworth; there are, however, few objects from inside the city, and whether York was settled at all at this period remains unclear. The fortress's fate after 400 AD is not clear, it is unlikely to have been a base of Romano-British power in opposition to the Anglians. flooded area reclamation would not be initiated until the 7th century under Edwin of Northumbria. After Angle settlement of Northern England, York was the Anglo-capital of Deira and one of the capitals when the kingdom united with Bernicia, later known as Northumbria.
