Fergus Mór

Fergus Mór mac Eirc (Scottish Gaelic: Fearghas Mòr Mac Earca; English: Fergus the Great) was a possible king of Dál Riata. He was the son of Erc of Dalriada.

While his historicity may be debatable, his posthumous importance as the founder of Scotland in the national myth of medieval and Renaissance Scotland is not in doubt. Rulers of Scotland from Cináed mac Ailpín until the present time claim descent from Fergus Mór.
