At some point, the young Óláfr was entrusted to the care of Henry I, King of England, and like the contemporaneous Scottish monarchs, Alexander I and David I, Óláfr appears to have been a protégé of the English king. As King of the Isles, Óláfr contracted marital alliances with neighbouring maritime rulers. Although he appears to have overseen successful military operations to reclaim the northernmost territories once controlled by his father, he may have witnessed the loss of authority in Galloway as well. Like his counterpart David I, Óláfr was a reformer and moderniser of his realm. However, his four-decade reign ended in abrupt disaster when he was assassinated by three nephews in 1153. Following the ensuing power struggle, Óláfr's son Guðrøðr overcame the kin-slayers, and assumed the kingship of the Kingdom of the Isles.
