branch duchies, Pomerania-Wolgast and Pomerania-Stettin, each appointed its own spiritual leader (called general superintendent as of 1563), seated in Greifswald for Pomerania-Wolgast and in Stettin for western Pomerania-Stettin, and, however, subordinate to Stettin, in Stolp (renamed as Słupsk) as of 1945) with subsidiary competence for the eastern part of Pomerania-Stettin. In 1544 the Cammin diocesan cathedral chapter elected as successor of Manteuffel, becoming the first Lutheran on the Cammin see, however, not confirmed by the Holy See. Suawe then introduced Lutheranism in the prince-episcopal state. His competence as spiritual Lutheran leader, however, was restricted to the prince-episcopal state (Hochstift), everywhere else in the former Cammin diocesan ambit superintendents, appointed by the respective ducal rulers, had taken Lutheran leadership. Protestantism had since been the prevailing Christian denomination in all of ducal and episcopal Pomerania. The Lutheran churches in the three states of ducal and prince-episcopal Pomerania ranked as state churches. Temporary partitions without share in the Pomeranian governments, such as Pomerania-Barth (1569–1605; ecclesiastically under the general superintendent in Greifswald) and Pomerania-Rügenwalde (1569–1620; ecclesiastically under the superintendent in Stolp till 1604, then Stettin), had no effect on the structure of the two ducal state churches. The Administrators of Cammin prince-bishopric, elected in 1557 and later, lacked theological skills and did not serve as spiritual leaders of the prince-episcopal Lutheran state church any more, but superintendents (Stiftssuperintendenten; i.e. superintendent of the Hochstift) were appointed since 1558. In the same year the Cammin prince-bishopric also established a Lutheran consistory of its own. In 1556 Pomerania-Wolgast had established its own consistory (). Its ambit comprised Pomerania north of the river Randow and west of the rivers Swine and Oder. Between 1575 and 1815 Stralsund, a city in Pomerania-Wolgast, maintained an own consistory for the Lutheran congregations within the city boundary. During the Thirty Years' War (1618–1648) Pomerania fell under Swedish occupation. In 1625 the Wolgast ducal branch was extinct in the male line and bequeathed to Stettin. With the extinction of the Stettin line too in 1637 the electors of Brandenburg inherited Pomerania, however, inhibited by the Swedish occupants. In 1653, after quarrels and negotiations Sweden and Brandenburg partitioned ducal Pomerania into Swedish Pomerania (comprising former Pomerania-Wolgast and the west of former Pomerania-Stettin), and Brandenburgian Pomerania (comprising the former Cammin prince-bishopric and central and eastern parts of former Pomerania-Stettin). As to the Lutheran state church of Swedish (Hither) Pomerania it took over the Wolgast-Pomeranian ecclesiastical
