Jaromar II, Prince of Rügen

During the early years of his reign, he tried to maintain peaceful relations with his neighbours, the Dukes of Pomerania, especially with the princes of Gützkow, who were vassals of Barnim I.

Jaromar II donated land to the three Cistercian monasteries in his territory, in Bergen auf Rügen, Neuenkamp, and Hilda.

In April of the same year, Jaromar II and Peder Bang landed on the main Danish island of Zealand and took the city of Copenhagen.

His widow, Margaret Sambiria, took up the regency for her underage son Eric V. She raised a peasant army, which was defeated by Jaromar II at Næstved.

After devastating Zealand, Scania and Lolland,[1] he landed with his army on Bornholm, where he destroyed the royal fortress at Lilleborg.
