Athelfrith of Bernicia

Athelfrith (died 616), in 593 became King of Bernicia. In 604 he conquered Deira and became the first King of Northumbria. Athelfrith was the first great leader among the Angles north of the River Humber. Bede called him an ambitious and powerful king who cruelly ravaged the Britons more than any other English leader. He was killed in battle against the East Angles.

 King of Bernicia 

Athelfrith was the son of Athelric of Bernicia and grandson of Ida of Bernicia.Mike Ashley, The Mammoth Book of British Kings and Queens (New York: Carroll & Graf, 1999), p. 275 In 593 Athelfrith became King of Bernicia. According to Frank Stenton "The continuous history of Northumbria, and indeed of England, begins with the reign of Athelfrith..." Among the northern Angles, Athelfrith was the first great leader.Frank Stenton, Anglo-Saxon England (Oxford: Oxford University Press, 1971), pp. 76–77 He gained more territory from the Britons than any other English leader.Steven Fanning, 'Bede, Imperium, and the Bretwaldas', Speculum, Vol. 66, No. 1 (Jan., 1991), p. 19

In 595 a large force of Britons, Gaels and Picts came together at Din Eydin (Edinburgh).Celtic Culture: A Historical Encyclopedia, ed. John T. Koch (Santa Barbara, CA: ABC-CLIO, 2006), p. 354 They attacked the Angles of Bernicia at a place identified as Catterick.Frank Stenton, Anglo-Saxon England (Oxford: Oxford University Press, 1971), p. 77 Among those killed at this battle called Catraeth, was Owen of Rheged, Athelfrith's enemy. Owen had killed Athelfrith's father, Athelric. The remaining force of Britons, Gaels and Picts was completely defeated, most of them being killed. In 603 Athelfrith fought another great battle at a place called Degsastan. Dál Riatan Scots, under their king Aedan mac Gabrain came against the English and were completely defeated.Peter Hunter Blair, Roman Britain and Early England; 55 B.C.–A.D. 871 (New York; London: W. W. Norton & Company, 1966), pp. 190-91 Athelfrith's victory eliminated the Scots as a threat for a long period of time in northern Britain. Bede, writing in 731, wrote that up to his day no king of the Scots had attempted to wage war against the northern English again. The only remaining enemy to cause Athelfrith any concern was the Britons of Strathclyde.

 King of Northumbria 

In 604 Athelfrith attacked Deira to his south. King Athelric of Deira was killed. Athelfrith also tried to kill Edwin of Deira, Athelric's brother, but Edwin escaped. He took Edwin's sister, Achaas, as his second wife. In 605 Athelfrith united the two kingdoms, Bernicia and Deira, into a single kingdom called Northumbria.C. W. Previté-Orton, Outlines of Medieval History (Cambridge: Cambridge University Press, 2013), p. 95 He must have spent the next few years setting up ways to govern such a large territory. He almost certainly set up fortifications as well. By 613 Athelfrith began trying to capture Edwin who had since been in exile in Gwnedd and Powys. He moved his army across the Pennines to Chester. When several monks were sent by the Britons to negotiate with Athelfrith they were killed.Mike Ashley, The Mammoth Book of British Kings and Queens (New York: Carroll & Graf, 1999), p. 276 Between 613 and 616 Athelfrith defeated the Britons in battle at Chester.Frank Stenton, Anglo-Saxon England (Oxford: Oxford University Press, 1971), p. 78 Edwin escaped again this time to Mercia, then to East Anglia. Athelfrith wanted the king, Raedwald of East Anglia, to murder Edwin, but he would not. Concerned that Athelfrith might attack East Anglia, Raedwald took his army and attacked Athelfrith. The two armies met at the River Idle near Doncaster. Not seeing the East Angles as a major threat, Athelfrith brought a smaller army. Athelfrith was killed after he was separated from his bodyguards. Edwin returned to Northumbria to become the king. At Athelfrith's death his family fled north to find safety. Eanfrith, the eldest son, found safety with the Picts.John Marsden, Northanhymbre Saga; the History of the Anglo-Saxon Kings of Northumbria (London: Kyle Cathie Limited, 1992), p. 61 He married the sister of Gartnait, King of the Picts. His half-brothers Oswald and Oswiu found safety with the Scots in Argyll.
