The House of Estridsen was a dynasty that provided the kings of Denmark from 1047 to 1412. The dynasty is named after its ancestor Estrid Svendsdatter. The dynasty is sometimes called the Ulfinger, after Estrid's husband, Ulf the Earl. The dynasty also provided three of the rulers of Sweden in the years 1125–1412.

The Norsemen were a North Germanic ethnolinguistic group of the Early Middle Ages, during which they spoke the Old Norse language. The language belongs to the North Germanic branch of the Indo-European languages and is the predecessor of the modern Germanic languages of Scandinavia. During the late 8th century, Norsemen embarked on a large-scale expansion in all directions, giving rise to the Viking Age. In English-language scholarship since the 19th century, Norse seafaring traders, settlers and warriors have commonly been referred to as Vikings. The identity of Norsemen derived into their modern descendants, the Danes, Icelanders, Faroe Islanders, Norwegians, and Swedes, who are now generally referred to as 'Scandinavians' rather than Norsemen.
