Godred Olafsson

Guðrøðr Óláfsson (died 10 November 1187), also known in Old Norse as Guðrøðr Ólafsson and Guðröðr Óláfsson, and in Gaelic as Gofhraidh mac Amhlaíbh,Gofraidh mac Amhlaoibh and Gofraid mac Amlaíb, and in English as Godred Olafsson, was a twelfth-century ruler of the kingdoms of Dublin and the Isles. Guðrøðr was a son of Óláfr Guðrøðarson, King of the Isles and Affraic, daughter of Fergus, Lord of Galloway. Throughout his career, Guðrøðr battled rival claimants to the throne, permanently losing about half of his realm to a rival dynasty in the process. Although dethroned for nearly a decade, Guðrøðr clawed his way back to regain control of a partitioned kingdom, and proceeded to project power into Ireland. Although originally opposed to the English invasion of Ireland, Guðrøðr adeptly recognised the English ascendancy in the Irish Sea region and aligned himself with the English. All later kings of the Crovan dynasty descended from Guðrøðr.

In the last year of his father's reign, Guðrøðr was absent at the court of Ingi Haraldsson, King of Norway, forging closer ties with the Kingdom of Norway. When Óláfr was assassinated by rival members of the Crovan dynasty in 1153, Guðrøðr returned to the Isles, overthrew his usurping cousins, and seized the throne for himself. Guðrøðr evidently pursued a more aggressive policy than his father, and the following year appears to have lent military assistance to Muirchertach Mac Lochlainn, King of Cenél nEógain in the latter's bid for the high-kingship of Ireland. Not long afterwards, Guðrøðr faced a dynastic challenge from his brother-in-law, Somairle mac Gilla Brigte, Lord of Argyll, whose son, as a grandson of Óláfr, possessed a claim to the throne. Late in 1156, Guðrøðr and Somaile fought an inconclusive sea-battle and partitioned the kingdom of the Isles between them. Two years later Somairle stuck again and forced Guðrøðr from the Isles altogether.
