Around 874 CE, Norwegian chieftain Ingolfur Arnarson established the first permanent Norse settlement in Iceland at Reykjavik, named for the geothermal steam rising from the land. The subsequent Age of Settlement (874-930) brought an estimated 10,000-20,000 Norse settlers, many fleeing the consolidation of power under King Harald Fairhair of Norway. These settlers established a pastoral society of independent farmsteads that culminated in the founding of the Althing parliament in 930.
