or Kenneth MacAlpin
died с 858, Forteviot, Scot.
First king of the united Scots of Dalriada and the Pict s.
He inherited (834?) the Scottish kingdom of Dalriada from his father, Alpin, who is thought to have been killed by the Picts. He also gained control over Pictavia, and from 843 the two kingdoms were gradually joined, an important step in the making of a unified Scotland . The union was probably accomplished both by intermarriage and by conquest.
