Áed of Scotland
Áed mac Cináeda (Anglicized Hugh, c. 840–878), son of Kenneth MacAlpin, became king of the Picts in 877 after the death of his brother Causantín. A later Gaelic poem, the Duan Albanach, gave him the epithet Fhionnscothach, ‘of the White Flowers’.
He ruled barely a year: the sources record him slain by kinsmen in 878, and later chroniclers blamed his successor Giric. His son Causantín reigned as Constantine II from 900.
