Osric, King of Deiri, and Eanfrid, of Bernicia, returned to paganism, and the whole people seem to have returned with them; since Paullinus, who was the first Archbishop of York, and who had converted them, thought proper to retire with Ethelburga, the queen dowager, into Kent. Both these Northumbrian kings perished soon after, the first in battle against Caedwalla, the Briton; the second by the treachery of that prince. Oswald, the brother of Eanfrid, of the race of Bernicia, united again the kingdom of Northumberland in the year 634, and restored the Christian religion in his dominions. He gained a bloody and well-disputed battle against Caedwalla; the last vigorous effort which the Britons made against the Saxons. Oswald is much celebrated for his sanctity and charity by the monkish historians, and they pretend that his relics wrought miracles, particularly the curing of a sick horse, which had approached the place of his interment [a]. [FN [a] Ibid. lib. 3. cap. 9.] He died in battle against Penda, King of Mercia, and was succeeded by his brother Oswy, who established himself in the government of the whole Northumbrian kingdom, by putting to death Oswin, the son of Osric, the last king of the race of Deiri. His son Egfrid succeeded him; who perishing in battle against the Picts, without leaving any children, because Adelthrid, his wife, refused to violate her vow of chastity, Alfred, his natural brother, acquired possession of the kingdom, which he governed for nineteen years, and he left it to Osred, his son, a boy of eight years of age. This prince, after a reign of eleven years, was murdered by Kenred, his kinsman, who, after enjoying the crown only a year, perished by a like fate. Osric, and after him Celwulph, the son of Kenred, next mounted the throne, which the latter relinquished in the year 735, in favour of Eadbert, his cousin-german, who, imitating his predecessor, abdicated the crown, and retired into a monastery. Oswolf, son of Eadbert, was slain in a sedition, a year after his accession to the crown; and Mollo, who was not of the royal family, seized the crown. He perished by the treachery of Ailred, a prince of the blood; and Ailred, having succeeded in his design upon the throne, was soon after expelled by his subjects. Ethelred, his successor, the son of Mollo, underwent a like fate. Celwold, the next king, the brother of Ailred, was deposed and slain by the people, and his place was filled by Osred, his nephew, who, after a short reign of a year, made way for Ethelbert, another son of Mollo, whose death was equally tragical with that of almost all his predecessors. After Ethelbert's death an universal anarchy prevailed in Northumberland, and the people having, by so many fatal revolutions, lost all attachment to their government and princes, were well prepared for subjection to a foreign yoke, which Egbert, King of Wessex, finally imposed upon them.
