Wartislaw I died between 1134 and 1148. His brother Ratibor I, duke in the Lands of Schlawe and Stolp, ruled in place of Wartislaw's sons, Bogislaw I and Casimir I until his death in about 1155. Then the duchy was split into Pomerania-Demmin, ruled by Casimir, including the upper Peene, Tollense, Dievenow and Rega areas, and Pomerania-Stettin, ruled by Bogislaw, including the lower Peene, Uecker, Oder, and Ihna areas. The Kolberg area was ruled in common as a codominion.
