Wartislaw III

Son of Casimir II of Pomerania-Demmin and Ingardis of Denmark, he was married to a Sophia of an unknown house.

1236 was a harsh year for Pomerania-Demmin, as Wartislaw lost a great part of his possessions to his rivaling neighbors Mecklenburg and the Margraviate of Brandenburg.

Yet, in the North, Wartislaw was able to expand his sphere of influence up to the Ryck river into the territory of Hilda, now Eldena Abbey set up there by the princes of Rügen.

Besides his struggles with his neighbors, Wartislaw enforced the Ostsiedlung in his duchy like his cousin and Pomeranian co-ruler Barnim I of Pomerania-Stettin.

He invited German nobles to join his court and settlers to develop the countryside, also, he granted German town law in its Lübeck law specification to the growing towns of Greifswald (1250), Demmin (~ 1250), Kolberg (now Kołobrzeg) (1255, along with Cammin bishop Hermann von Gleichen), Greifenberg (now Gryfice) (1262), also, together with Barnim I of Pomerania-Stettin, Wolgast (1257), Wollin (now Wolin) (1262) and Stavenhagen (1252).
