In Kent, Earconbert succeeds Eadbald in 640 A.D., and takes vigorous measures for the suppression of idolatry. His daughter, Earcongota, and many other high-born English ladies enter the religious life in Gaul, for convents are still scarce in England.
In Chapter 9, reverting to the history of Northumbria, Bede tells us of the death of Oswald at Maserfelth in 642, and relates at length various miracles wrought by his relics. Oswald is succeeded by Oswy in Bernicia and in Deira by Oswin. The latter is treacherously murdered by Oswy; his character is described. The death of Aidan (in 651) immediately follows that of his beloved king; Aidan's miracles are related, and a warm tribute is paid to his character, in spite of the inevitable error with regard to Easter, which is severely condemned.
In Chapter 18, passing again to East Anglian history, we hear of King Sigbert's services to education, and of his retirement to a monastery from which he was forcibly drawn to fall in battle against the Mercians. (The chronology is here very vague.) A vision of the Irish St. Fursa, who founded the monastery of Cnobheresburg in East Anglia is told in detail. Changes in the episcopate in East Anglia and elsewhere are mentioned. Deusdedit succeeds Honorius as Archbishop of Canterbury in 654.
Again, a Northumbrian prince gives a fresh impulse to the spread of Christianity. In 653 the Middle Angles (who occupied a part of Mercia) are converted, their prince, Peada, being persuaded chiefly by his brother-in-law, Alchfrid, a son of Oswy. Four priests are sent to them to preach and baptize, Cedd, Adda, Betti, and Diuma, and Diuma becomes bishop of the Middle Angles and Mercians. Similarly, at this time, King Sigbert of Essex listens to the exhortations of his friend, King Oswy, and, at the preaching of Cedd, the East Saxons receive the faith a second time. Cedd becomes their bishop. Sigbert's tragic death is related. His successor, Suidhelm, receives baptism at the hands of Cedd. The foundation of Lastingham by Ethelwald of Deira and its consecration by Cedd are described. Cedd dies of the plague of 664.
Meanwhile, important political changes have taken place in the north: the defeat and death of Penda at the Winwaed in 655 are followed by Oswy's rule, which established Christianity in Mercia, in spite of a successful rebellion after three years, when the Mercians threw off the yoke of Northumbria and set up Penda's son, Wulfhere, as their king.
