Editing Cadfan ap Iago (section)

== Fictionalization by and after Geoffrey of Monmouth ==
The largely fictional stories of ancient Britain written by [[Geoffrey of Monmouth]] use the names of many historical personages as characters, and the use of these names is a literary convenience made in order to advance the plot of Geoffrey's stories. One of these stories uses the names of Cadfan and other contemporary people, telling of how a certain Edwin spent his exiled youth at the court of King Cadfan, growing up alongside Cadfan's son, the future King Cadwallon. There is no historical basis for this story, as is readily acknowledged in the preface of works on the subject.<ref>{{Citation |last=Menzies |first=Louisa L.

Nevertheless, a "traditional" story arose blending Geoffrey's fiction with known history, implying that the future King [[Edwin of Northumbria]] had actually spent his youth at the court of King Cadfan, growing up alongside Cadfan's son, the future King Cadwallon. In point of fact, Cadwallon and Edwin were enemies with no known youthful connections: King Edwin invaded Gwynedd and drove King Cadwallon into exile, and it would be Cadwallon, in alliance with [[Penda of Mercia]], who would ultimately defeat and kill Edwin in 633 at the [[Battle of Hatfield Chase]] ({{langx|cy|Gwaith Meigen}}). The story that they had spent an idyllic youth together may have had a romantic appeal.

What is known from history is that in 588 King [[Ælla of Deira]] died, and [[Æthelfrith|Æthelfrith of Bernicia]] took the opportunity to invade and conquer [[Deira]], driving Ælla's 3-year old infant son, the future [[Edwin of Northumbria]], into exile. Edwin would eventually ally himself with [[Rædwald of East Anglia]] in 616, defeating and killing Æthelfrith and becoming one of [[Northumbria]]'s most successful kings. Edwin's life in exile is unknown, and there is no historical basis for placing him at the court of King Cadfan.<ref>{{Citation |last=Hunt |first=William |author-link=William Hunt (clergyman) |year=1899 |editor-last=Stephens |editor-first=W.
