Áedán mac Gabráin

Áedán mac Gabráin (pronounced [ˈaiðaːn mak ˈɡavɾaːnʲ] in Old Irish) was a king of Dál Riata from c. 574 until c. 609. The kingdom of Dál Riata was situated in modern Argyll and Bute, Scotland, and parts of County Antrim, Ireland. Genealogies record that Áedán was a son of Gabrán mac Domangairt.

He was a contemporary of Saint Columba, and much that is recorded of his life and career comes from hagiography such as Adomnán of Iona's Life of Saint Columba. Áedán appears as a character in Old Irish and Middle Irish language works of prose and verse, some now lost.

The Irish annals record Áedán's campaigns against his neighbours, in Ireland, and in northern Britain, including expeditions to the Orkney Islands, the Isle of Man, and the east coast of Scotland. As recorded by Bede, Áedán was decisively defeated by Æthelfrith of Bernicia at the Battle of Degsastan. Áedán may have been deposed, or have abdicated, following this defeat. His date of death is recorded by one source as 17 April 609.

The sources for Áedán's life include Bede's Historia ecclesiastica gentis Anglorum; Irish annals, principally the Annals of Ulster and the Annals of Tigernach; and Adomnán's Life of Saint Columba. The Senchus fer n-Alban, a census and genealogy of Dál Riata, purports to record his ancestry and that of his immediate descendants. None of these sources are contemporary. Adomnán's work was written in the very late 7th century, probably to mark the centenary of Columba's death. It incorporates elements from a lost earlier life of Columba, De virtutibus sancti Columbae, by Cumméne Find. This may have been written as early as 640; neither the elements incorporated from Cumméne's work nor Adomnán's own writings can be treated as simple history. Bede's history was written 30 years after Adomnán's. The surviving Irish annals contain elements of a chronicle kept at Iona from the middle of the 7th century onwards, so that these too are retrospective when dealing with Áedán's time.
