power became great enough for Bede to recognise him as the successor to the imperium of Æthelberht. Bede also called him Rex Anglorum, the 'King of the Angles', a term that Rædwald's contemporaries would have used for their overlord. It is unclear where his power was centred or even how he established his authority over the Angles of eastern England. By Edwin's debt of allegiance to him, Rædwald became the first foreign king to hold direct influence in Northumbria. He would have been instrumental in Edwin's secure establishment as king of both Deira and Bernicia. The development of Gipeswic During the first quarter of the 7th century, the quayside settlement at Gipeswic (Ipswich) became an important estuarine trading centre, receiving imported goods such as pottery from other trading markets situated around the coasts of the North Sea. Steven Plunkett suggests that the founding of Gipeswic took place under Wuffingas supervision. It took another hundred years for the settlement to develop into a town, but its beginnings can be seen as a reflection of the personal importance of Rædwald during the period of his supremacy. The excavated grave-goods of the Anglo-Saxon cemetery at Gipeswic, including those found in burials under small barrows, were not particularly wealthy or elaborate. They lacked the strong characterization of a neighbouring late 6th century cemetery at a higher crossing of the river. One exception was a furnished grave that has been suggested to be that of a visitor from the Rhineland. Death Rædwald is believed to have died around 624: his death can be located only within a few years. He must have reigned for some time after Æthelberht died, in order for him to have been noted as a bretwalda. Barbara Yorke suggests that he died before Edwin converted to Christianity in 627 and also before Paulinus became bishop of Northumbria in 625. His death is recorded twice by Roger of Wendover, in 599 and in 624, in a history that dates from the 13th century but appears to include earlier annals of unknown origin and reliability. Plunkett notes that the earlier date of 599 is now taken as a mistaken reference to the death of Rædwald's father, Tytila, and the later date is commonly given for the death of Rædwald. He was succeeded by his pagan son Eorpwald, who was later persuaded to adopt Christianity by Edwin of Northumbria. Sutton Hoo Rædwald lived at
