The West Saxons, by conquest, extended their rule westward and northward, and missionary enterprise followed the course of military success and subsequent civil protection. The original British occupiers of the land withdrew to Wales, or else became subject to the conquerors. Similar had been the course of events which followed the taking of Kent by the Jutes. So when Augustine arrived he was welcomed by Aethelberht, whose wife Bertha, a Frankish princess, was already a Christian. Augustine having founded the see of Canterbury, was soon enabled, by the help of political and social influence, to effect the establishment of other sees. Rochester, London, and York were soon centres of activity; but these neighbour principalities had not, ecclesiastically, affected the territories that were close to their respective domains; for the kingdom of the South Saxons remained, nearly two centuries after Aelle's conquest, in the same heathen condition as prevailed in his day. Bede relates that at Bosham, Dicul had founded a monastery where, "surrounded by woods and water, lived five or six brethren, serving the Lord in humility and poverty." But "no one cared to emulate their life, or listen to their teaching." Dicul came from Ireland, and it is supposed that he had been educated in the monastic centre of missionary life which in the sixth century had been founded there. It is not, however, known how these few men found their way to the South Saxon shores, and their presence there had no influence upon the minds of those invaders who had possessed themselves of the adjacent lands. A quarrel in the Northumbrian kingdom was the cause which sent a missionary to Sussex in 680 A.D.
