Edred was a mere youth when he succeeded to the crown, a circumstance which the Northumbrians were not slow to take advantage of, and instantly attempted to throw off their allegiance; but after a variety of contests they were ultimately subdued, and Earl Oswulf appointed to govern them. The last-mentioned personage, who was an Englishman, appears to have acted with no less vigour than prudence, erecting many strongholds, and placing efficient garrisons within them, to keep the natives of the newly-conquered province in subjection. These methods were so efficacious that Northumbria remained, for a long time tranquil, and the descendants of Oswulf were earls there for quite a hundred years.
The young king, perfectly master of his own kingdom, and respected by the Scots, had now time to direct his attention to religious affairs, and during his brief reign contributed largely to churches and monasteries. To this course of action he was led by the powerful influence of Dunstan, one of the most remarkable personages in old English history, and the first of those great ecclesiastical statesmen who have played a leading part in the annals of Britain.
Dunstan was born in the year 925, and being of aristocratic family, rapidly obtained advancement in the Church. By the age of eighteen he had become abbot of Glastonbury, and from the first proved an extremely able administrator, restoring the discipline of the monastery, and rebuilding the great church. His personal character appears to have been morbid and eccentric, but the stories told concerning him come for the most part from his enemies, and it is extremely difficult to know what to make of them. He had been an old playmate of Edred's, and the weak and sickly king was entirely in his hands. Dunstan by no means confined his activity to ecclesiastical matters, but took an active part in the war against the Northumbrian Danes. It was probably on his advice that the country was bestowed as an earldom on Oswulf. His object here, as elsewhere, was to allow the smaller kingdoms to maintain their individuality, their own laws and customs, subject to the leadership of Wessex. Such a policy was naturally not popular in Wessex, and when Edred, "the Chosen," as he was called, died in 955, Dunstan was doomed to a period of eclipse.
