Cadwallon ap Cadfan ab Iago
Alex Woolf (2004) argues that the Cadwallon who fought the Northumbrians was the son of Guitcon, son of Sawyl Penuchel, and was mistakenly inserted by later genealogists into the pedigree of the kings of Gwynedd. Nicholas Evans (2011) describes this theory as “plausible”.
The history of the Cadwallon who fought in Northumbria seems to be roughly this: Edwin, king of Northumbria chased Cadwallon to Priestholm, a small island off Anglesey, and beseiged him there, probably in 632. Cadwallon seems to have escaped and sought refuge in Ireland. Cadwallon returned, and in alliance with Penda, king of Mercia, fought and killed Edwin at Hatfield Chase in 633. Northumbria then split up into the kingdoms of Deira and Bernicia. The king of Deira, Osric, attacked Cadwallon, but Cadwallon defeated and killed him. Cadwallon also killed the king of Bernicia, Eanfrith, who had been attempting to negotiate peace with him. Cadwallon ruled Northumbria for a year; his reign was remembered by Northumbrians for its cruelty and destruction. Eanfrith’s brother, Oswald, defeated and killed Cadwallon in the Battle of Heavenfield.
The outcome of the battle ended any serious hope the Britons had of retaking Britain from the Saxons.
Cadwallon is a prominent figure in later Welsh literature.
Events
Date of Birth: born about 586.
This estimated date is given by Bartrum (EVWG [3]).
(possible) Date of Death: 635.
The date is given by Kirby (p. 91). Plummer (2:121) argues that Bede’s account should be interpreted as giving the date as 634. Annales Cambriæ (Williams p. 7) records the death under the year 631. If Woolf (2004) is correct, these dates are for a different Cadwallon.
(possible) Place of Death: “Riuus Denisi”, Northumbria. (The Rowley Burn)
Bede (Lib. III, Cap. I) describes Cadwallon’s place of death as “riuus Denisi”, which is said to be the stream now known as the Rowley Burn.
Relationships
Father: Cadfan ab Iago.
This relationship is shown by Bartrum (EVWG [3]). One of the Welsh triads (Bromwich 29), in one version, refers to Cadwallon as Cadfan’s adopted son.
(possible) Mother: Tandreg Ddu ferch Cynan Garwyn.
This relationship is shown by Bartrum (EVWG [3]). Baldwin (LaI) states that it is difficult to trust the late source for this, as it contains much mythological material, but the relationship is chronologically possible. He regards it as unproven.
Spouse: uncertain.
Bartrum (EVWG [3]) shows Cadwaladr’s wife as a daughter of Pybba, and sister of Penda, king of Mercia. Baldwin (LaI) notes that the source for this, Geoffrey of Monmouth, is too unreliable to be accepted as an authority.
