- Iago ap Idwal
Iago ap Idwal (ruled 950 - 979) was a King of Gwynedd and possibly Powys, also called
King of the Britons by theAnnals of Ulster .Iago was the son of
Idwal Foel , and on his father's death in battle in 942 would have expected to succeed to the rule of Gwynedd together with his brotherIeuaf ab Idwal . HoweverHywel Dda King ofDeheubarth took the opportunity to invade Gwynedd and dispossess the young princes.On Hywel's death in 950 Iago and Ieuaf were able to claim the throne of Gwynedd, driving out the sons of Hywel. Fighting continued between the two dynasties, with Iago and Ieuaf raiding as far south as
Dyfed in 952 and the sons of Howell raiding as far north as the Conwy valley in 954 before being defeated in battle atLlanrwst and chased back toCeredigion .The sons of Idwal quarrelled and Iago took Ieuaf prisoner in 969. Despite a temporary defeat in 974 Iago ruled Gwynedd until 979 when he in turn was taken prisoner by Ieuaf's son,
Hywel ab Ieuaf , who took over his kingdom. There appears to be no record of Iago's fate.Iago was the father of
Cynan ab Iago .References
