What was an island that Guðrøðr Óláfsson ruled over?
Guðrøðr Óláfsson Guðrøðr Óláfsson (died 10 November 1187) 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.
Brattahlíð Brattahlíð, often anglicised as Brattahlid, was Erik the Red's estate in the Eastern Settlement Viking colony he established in south-western Greenland toward the end of the 10th century. The present settlement of Qassiarsuk, approximately 5 km southwest from the Narsarsuaq settlement, is now located in its place. The site is located about 96 km from the ocean, at the head of the Tunulliarfik Fjord, and hence sheltered from ocean storms. Erik and his descendants lived there until about the mid-15th century. The name "Brattahlíð" means "the steep slope".
