10th-century Danish women

Thyra or Thyri (Old Norse: Þyri or Þyre) was the wife of King Gorm the Old of Denmark, and one of the first queens of Denmark believed by scholars to be historical rather than legendary. She is presented in medieval sources as a wise and powerful woman who ordered the building or fortification of the Danevirke, consistent with her commemoration on multiple Viking Age runestones. These include those at Jelling which was the seat of power for her dynasty.

"Świętosława" is a name that was used in the past by historians to refer to a Polish princess who was the daughter of Mieszko I of Poland, sister to Bolesław I of Poland, and purported wife of two Scandinavian kings. Modern research suggests it was likely not her name, and that she was only a wife to one of aforementioned kings, Sweyn Forkbeard.
