The House of Estridsen[1][2] 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 Jarl. The dynasty also provided three medieval rulers of Sweden and one of Norway. Their family coat of arms became the coat of arms of Denmark and thereby influenced the coat of arms of Tallinn and the coat of arms of Estonia.
The Royal Court of Denmark does not differentiate between different royal houses among the early Danish kings, but uses the term "the descent of Gorm the Old" about all the pre-Oldenburg monarchs.[3]
