Dál Riata in Depth

History

The 11th-century Duan Albanach (Song of the Scots) tells that the three sons of Erc—Fergus Mór, Loarn and Óengus—conquered Alba (Scotland) in around 500. The 8th-century writer Bede offers another, and probably older, account wherein Dál Riata was conquered by Irish Gaels led by a certain Reuda. Old Irish dál means 'portion' or 'share', and is usually followed by the name of an eponymous founder. Bede's tale may come from the same root as the Irish tales of Cairpre Riata and his brothers, the Síl Conairi (sons/descendants of Conaire Cóem and Conaire Mór). The story of Dál Riata moves from foundation myth to something nearer to history with the reports of the death of Comgall mac Domangairt around 540 and of his brother Gabrán around 560.
