Jaromar I, Prince of Rügen
Jaromar I was a Prince of Rügen between 1170 and 1218.
Background
Jaromar was a Ranish nobleman, who was a native of the island of Rügen. Jaromar rose to be ruler of the Principality of Rügen as result of the Danish conquest of Rügen in 1168. His predecessor was Tetzlav, who in 1168 had submitted to the Danish.
Danish conquest
The Danish organized a war to Christianize the formerly pagan islanders and to destroy the pagan strongholds and cult places. This action also served to have their piracy and raids to Danish lands ended. The Danish navy, led by among other militaries, Archbishop Absalon, conquered and destroyed the fortress of Cape Arkona. The temple fortress of Arkona (Jaromarsburg) had been the religious centre of the Slavic Rani. The island of Rügen was incorporated into the Danish Archdiocese of Roskilde.
The Danish set up Rügen as their vassal. Jaromar, who was not committed to hitherto pagan rulers of the island, accepted Christianity and promised loyalty to King Valdemar I of Denmark.
