Before 572 Æthelfrith King Northumbrians was born to Æthelric King Bernicia.
In 572 [his father] Æthelric King Bernicia died.
Anglo-Saxon Chronicle. 603. This year Aeden (age 43), king of the Scots, fought with the Dalreathians, and with Ethelfrith (age 31), king of the Northumbrians, at Theakstone; where he lost almost all his army. Theobald also, brother of Ethelfrith (age 31), with his whole armament, was slain. None of the Scottish kings durst afterwards bring an army against this nation. Hering, the son of Hussa, led the army thither.
In 603 the Battle of Degsastan was fought between Æthelfrith King Northumbrians (age 31) and a combined Irish and Scottish army commanded by Áedán mac Gabráin King of Dál Riata. Æthelfrith's army won a decisive victory although his brother Theobald was killed by Máel Umai mac Báetáin.
[his brother] Theobald Bernicia was killed.
Anglo-Saxon Chronicle. 607. This year Ceolwulf fought with the South-Saxons. And Ethelfrith (age 35) led his army to Chester [Map]; where he slew an innumerable host of the Welsh; and so was fulfilled the prophecy of Augustine, wherein he saith "If the Welsh will not have peace with us, they shall perish at the hands of the Saxons." There were also slain two hundred priests18, who came thither to pray for the army of the Welsh. Their leader was called Brocmail, who with some fifty men escaped thence.
Note 18. It was originally, perhaps, in the MSS. ICC. the abbreviation for 1,200; which is the number of the slain in Bede. The total number of the monks of Bangor is said to have been 2,100; most of whom appear to have been employed in prayer on this occasion, and only fifty escape by flight. Vide Bede, "Hist. Eccles." ii. 2, and the tribe of Latin historians who copy him.
In 617 Raedwald King East Anglia (age 47) and his son Raegenhere Wuffingas fought the Battle of the River Idle which took place at the River Idle Markham Moor Retford which forms the western border of the Isle of Lindsey [Map].
Raegenhere Wuffingas was killed.
Anglo-Saxon Chronicle. 617. This year was Ethelfrith (age 45), king of the Northumbrians, slain by Redwald (age 47), king of the East-Angles; and [his brother-in-law] Edwin (age 31), the son of Ella, having succeeded to the kingdom, subdued all Britain, except the men of Kent alone, and drove out the Ethelings, the sons of Ethelfrith (age 45), namely, [his son] Enfrid (age 27), [his son] Oswald (age 13), [his son] Oswy (age 5), [his son] Oslac, [his son] Oswood, [his son] Oslaf, and [his son] Offa.
Anglo-Saxon Chronicle. 634. This year Osric, whom Paulinus baptized, succeeded to the government of King of Deira. He was the son of Elfric, the uncle of [his brother-in-law] Edwin. And to Bernicia succeeded [his son] Eanfrith (age 44), son of Ethelfrith. This year also Bishop Birinus first preached baptism to the West-Saxons, under King Cynegils. The said Birinus went thither by the command of Pope Honorius; and he was bishop there to the end of his life. [his son] Oswald (age 30) also this year succeeded to the government of the King Northumbrians, and reigned nine winters. The ninth year was assigned to him on account of the heathenism in which those lived who reigned that one year betwixt him and Edwin.
Anglo-Saxon Chronicle. 685. This year King Everth (age 40) commanded Cuthbert (age 51) to be consecrated a bishop; and Archbishop Theodore (age 83), on the first day of Easter, consecrated him at York Bishop of Hexham; for Trumbert had been deprived of that see. The same year Everth (age 40) was slain by the north sea, and a large army with him, on the thirteenth day before the calends of June. He continued king fifteen winters; and his brother Elfrith succeeded him in the government. Everth (age 40) was the son of Oswy. Oswy of Ethelferth, Ethelferth of [his father] Ethelric, Ethelric of Ida, Ida of Eoppa. About this time Ceadwall (age 26) began to struggle for a kingdom. Ceadwall (age 26) was the son of Kenbert, Kenbert of Chad (age 95), Chad of Cutha, Cutha of Ceawlin, Ceawlin of Cynric, Cynric of Cerdic. Mull, who was afterwards consigned to the flames in Kent, was the brother of Ceadwall (age 26). The same year died Lothhere, King of Kent; and John was consecrated Bishop of Hexham, where he remained till Wilferth was restored, when John was translated to York on the death of Bishop Bosa. Wilferth his priest was afterwards consecrated Bishop of York, and John retired to his monastery [Map]21 in the woods of Delta. This year there was in Britain a bloody rain, and milk and butter were turned to blood.
