Partition of 1532: Pomerania-Stettin and Pomerania-Wolgast
After Bogislaw X's death, his sons initially ruled in common. Yet, after Georg's death, the duchy was partitioned again between Barnim IX, who resided in Stettin, and Phillip I, who resided in Wolgast. The border ran roughly along the Oder and Swine rivers, with Pomerania-Wolgast now consisting of Hither or Western Pomerania (Vorpommern, yet without Stettin and Gartz (Oder) on the Oder river's left bank, and with Greifenberg on its right bank), and Pomerania-Stettin consisting of Farther Pomerania. The secular possessions of the Diocese of Cammin around Kolberg (Kolobrzeg) subsequently came controlled by the dukes, when members of the ducal family were made titular bishops of Cammin since 1556.
Despite the division, the duchy maintained one central government.
