Vitslav I, Prince of Rügen
Wizlaw I (c. 1180 – 7 June 1250), variously called Vislav, Vizlav, Wislaw, Wizlaw and Witslaw in English sources, was a prince of Rügen.
The first surviving mention of Vitslav I dates to 1193. His parents were Jaromar I and Hildegard of Denmark (ca. 1135), the daughter of Canute V of Denmark (ca. 1128–1157) and (Sophie?) Sverkersdotter of Sweden.
In 1219, Vitslav took part in a campaign by his feudal lord, the King of Denmark Valdemar II, to Estonia. Following the resignation of his brother, Barnuta, Vitslav I was mentioned in documents in 1221 as the Prince of Rügen. This year is also first time that there is a record of German settlers in the mainland territories of Rügen. In subsequent years, he again took part in wars on the side of Valdemar II, for example, in 1225 at the Battle of Mölln and in 1227 at the Battle of Bornhöved. Despite the defeat of the Danes, he held firmly to his feudal relation with Denmark. In 1231 he founded the Cistercian monastery of Neuenkamp (now Franzburg). In 1234, he gave Stralsund its town rights and granted the town privileges such as fishing rights and exemption from duty. During his reign, the Principality of Rügen reached its greatest extent.
With his wife Margarete (before 1200 - 5 March 1232), probably a niece of bishop Absalon and possibly a daughter of Sverker II of Sweden and Benedicta Ebbesdotter of Hvide, he had six sons whose names are known:
