The House of Knýtlinga refers to a royal dynasty that originated from the descendants of King Knut the Great, who ruled over England, Denmark, Norway, and parts of what is now Sweden in the early 11th century. This house is significant in the history of Northern Europe, as it played a crucial role in the unification of these regions under a single monarch. Members of the House of Knýtlinga were known for their influence and power during the Viking Age and the early medieval period. The dynasty's legacy includes the spread of Christianity and the establishment of strong political ties between the Scandinavian countries and England.
