Icelanders
Icelanders are the predominant ethnic group in Iceland, numbering around 390,000 within the country, with origins tracing to Norse Viking settlers from Scandinavia and Celtic women primarily from Ireland and Scotland during the late 9th and early 10th centuries.[1][2] Genetic studies reveal a founder effect leading to exceptional homogeneity, with paternal lineages largely Norse (75-80%) and maternal lineages showing 60-75% Gaelic ancestry, facilitating unique population-level research due to comprehensive genealogical records spanning over a millennium.[1][2] They speak Icelandic, a North Germanic language evolved minimally from Old Norse, enabling contemporary readers to comprehend medieval texts like the sagas with minimal adaptation.[3] This linguistic continuity underscores a rich literary heritage, including the Eddas and family sagas composed in the 12th-14th centuries, which form a cornerstone of their cultural identity.[3] Icelanders exhibit traits such as direct communication, high trust in social institutions, and a pragmatic adaptation to their harsh subarctic environment, historically reliant on fishing, farming, and now geothermal and renewable energy.[4] A diaspora of tens of thousands, concentrated in Canada, the United States, and Nordic neighbors, preserves these ties through festivals and heritage societies, though emigration rates remain elevated relative to population size.[5]
