The "House of Knýtlinga" refers to a royal dynasty in medieval Europe, particularly associated with the descendants of King Knut the Great. This house emerged in the early 11th century and included rulers from Denmark, England, and Norway. The dynasty is notable for its influence on the political landscape of Northern Europe during the Viking Age. Members of the House of Knýtlinga played significant roles in the unification of Scandinavia and the spread of Christianity in the region. The lineage is often linked to various historical figures, including Harald Hardrada and Cnut's sons, who continued the legacy of their father across multiple kingdoms.
