Kenneth McAlpin

The Danes, already well-established through the Hebrides and on the mainland and supported with on-going North Sea crossings, battled with Alba’s Picts in 839 and utterly defeated them. The North of Scotland experienced a gradual population migration, under the Norse pressure, with the Scots of the west encroaching on the Picts of the east.

Four years later in 843 Kenneth MacAlpin, (Cináed mac Ailpín) son of Alpin, 34th King of Dalriada, asserted himself as the first King of the Picts and Scots.
