978/981 - after 1017
House: Piast
Titles: Queen consort of Sweden, Queen consort of Denmark
Daughter of Mieszko I was a Polish princess, sister to Bolesław I of Poland, and is associated with the name Świętosława by some historians. She was purportedly married to two Scandinavian kings, although modern research suggests she was only the wife of Sweyn Forkbeard. Chroniclers mention her as the mother of Cnut the Great and Harald II of Denmark, and possibly Olof Skötkonung.
Her identity is often confused with Sigrid the Haughty, a figure in Icelandic sagas, but this account is considered less reliable. Some scholars speculate she might be the same as Gunhild of Wenden, mentioned by Snorre Sturlasson. Polish genealogist Rafał Prinke suggests that the chroniclers combined the roles of two wives of Sweyn Forkbeard, with the Polish princess being the mother of Cnut, Harold, and a daughter named Świętosława.
She died after 1017, with no specific cause of death or burial place recorded. Her succession details remain unclear.
