Seems to have taken the throne of Gwynedd on the death of Cadwallon in 634, possibly because Cadwallon's son may have been young. In 655 he campaigned with Penda of Mercia against Oswiu of Northumbria. According to the Northern History, quoted by Nennius, he departed the night before the battle at the Winwaed in which Penda was killed. He was subsequently known as Cadafael Cadomedd (‘the Battle-dodger’).
