He was succeeded by his son Eorpwald, who was converted by missionaries sent by Edwin king of Northumbria. His reign, however, was short, and at his death the people again relapsed into heathenism. Christianity was finally established among the East Angles by Sigeberht, Eorpwald's brother, and it was due to him and through his influence that Felix, a missionary from Burgundy, was enabled to fix his see at Dunwich, A.D. 630. #Felix# (630-47) must needs have been a man strong in his Faith; he christianised the whole of that district which now includes Norfolk, Suffolk, and Cambridgeshire. He died on the 8th of March, and was canonized after death. Felixstowe, where he is said to have founded schools, keeps his memory green in the East Country; but Dunwich, where he fixed his see, has long since been covered by the encroaching waves. Sigeberht resigned the crown to his kinsman Egric, and had entered a monastery to finish his days in peace. But the kingdom was invaded by the Mercians under Penda, and the peaceful old king was compelled to appear in the field to give heart and courage to the East Angles. He, however, declined to employ carnal weapons, and went out against his enemies armed with nothing more formidable than a wand. He was killed in the ensuing engagement, and his successor, Egric, shared the same fate. The administration of the two successors to Felix lasted twenty-two years, from A.D. 647-69. The East Anglian see was then divided by Theodore, Archbishop of Canterbury, into two separate administrations, #Acci#, the fourth successor to Felix, taking Dunwich, while #Beadwin# was consecrated to the see of Elham. From this date there were two lines of East Anglian Bishops; ten diocesans followed after Acci at Dunwich, and nine after Beadwin at Elmham. #St. Humbert# (828-78) was the last of the Bishops of Elmham; he crowned St. Edmund king of the East Angles, and both were murdered by the Danes under Hinguar in 870. After Humbert's death the two sees were again united under #Wildred#, who at this time was Bishop of Dunwich; he, however, preferred Humbert's see at Elham, and removed there, and so the bishopric of Dunwich became extinct. During the next two hundred years (870-1070), there were thirteen bishops of Elmham, and then Elmham shared a similar fate to Dunwich, and the see was moved to Thetford by #Herfast#, a chaplain of William the Conqueror. William of Malmesbury records that Herfast had decided to go down to posterity as a man _who had done something_, and fixed on this removal as an easy solution of the difficulty. #William Galsagus# (1086-91) or de Beaufeu succeeded Herfast, and he in turn was succeeded by Herbert de Losinga, who became first Bishop of Norwich.
