Born c.1113 in Morvern, Argyll, Somerled was half-Norse through his mother. His father's lineage was reputedly of royal blood. Forced into exile in Ireland his family convinced the Colla clan to help them reclaim their Argyll lands, but his father was killed in the attempt. Growing up and living as a warrior hermit, Somerled led the inhabitants of Morvern against the Norse and regained his family's lands thus becoming master of large tracts of northern Argyll. Soon after, he took control of the south of Argyll and pronounced himself Thane of Argyll. At the same time, King David I was waging war against the Norwegians and Somerled's stature and currency rose with the king accordingly.
