Áedán MacGabran King of Scotland, Aidan The Treacherous,
Áedán (Aidan) mac Gabráin was a king of Dál Riata from about 574 until his death in 606, 608 or 609.
Aedan was established as king by Columba upon the death of his cousin, Conall. King Aidan secured the independence of Dalriada in about 575. He was ordained King of Dalriada by Saint Columba. He was succeeded by his son Eochodius or Eocha Buidhe. 
The kingdom of Dál Riata reached its height under Áedán mac Gabráin (r. 574–608). Known from Adomnán of Iona's Life of Saint Columba and from many entries in the Annals.
The story of Aedán's birth as the twin of Brandub, both sons of Eochu and of his being fostered by Gabrán is told in the Gein Branduib maic Echach ocus Aedáin maic Gabráin
