Aedan of Dalriada

Aedan mac Gabhran was a king of the Dalriada Scots. He reigned from about 574 to 606 or 608 and was allegedly over 70 at his death. He was the son of Gabhran, king of Dalriada, and became king after the death of his kinsman, King Conall, when he was crowned at Iona by Saint Columba. He refused to allow his kingdom to remain dependent on the Irish Dalriada, but coming into collision with his southern neighbours he led a large force against Æthelfrith, king of the Northumbrians, and was defeated at a place called Daegsanstane, probably in Liddesdale.
