6. =The Archbishopric of Canterbury.=--After a short stay Augustine revisited Gaul and came back as Archbishop of the English. AEthelberht gave to him a ruined church at Canterbury, and that poor church was named Christ Church, and became the mother church of England. From that day the Archbishop's See has been fixed at Canterbury. If Augustine in his character of monk led men by example, in his character of Archbishop he had to organise the Church. With AEthelberht's help he set up a bishopric at Rochester and another in London. London was now again an important trading city, which, though not in AEthelberht's own kingdom of Kent, formed part of the kingdom of Essex, which was dependent on Kent. More than these three Sees Augustine was unable to establish. An attempt to obtain the friendly co-operation of the Welsh bishops broke down because Augustine insisted on their adoption of Roman customs; and Lawrence, who succeeded to the archbishopric after Augustine's death, could do no more than his predecessor had done. 7. =Death of AEthelberht. 616.=--In =616= AEthelberht died. The over-lordship of the kings of Kent ended with him, and Augustine's church, which had largely depended upon his influence, very nearly ended as well. Essex relapsed into heathenism, and it was only by terrifying AEthelberht's son with the vengeance of St. Peter that Lawrence kept him from relapsing also. On the other hand, Raedwald, king of the East Anglians, who succeeded to much of AEthelberht's authority, so far accepted Christianity as to worship Christ amongst his other gods.
