Information about King Donald MacAlpin of Scotland

Domnall mac Ailpín (Modern Gaelic: Dòmhnall mac Ailpein, anglicised sometimes as Donald MacAlpin, known in most modern regnal lists as Donald I) was King of the Picts from 858 to 862. He followed his brother Kenneth I to the Pictish throne.

The Chronicle of the Kings of Alba says that Domnall reigned for four years, matching the notices in the Annals of Ulster of his brother's death in February 858 and his own in April 862.
