Was a duchy in Pomerania on the southern coast of the Baltic Sea, ruled by dukes of the House of Pomerania (Griffins). It was partitioned and reunited several times. We only take in account the partition into the Stettin and Wolgast Lines based on G. Droysen's “Historischer Handatlas” (1886). In fact, none of the partitions had a hereditary character. The only exception was during a war with the Margraviate of Brandenburg, when in 1338 Barnim III of Pomerania-Stettin was granted his partition as a fief directly from the Holy Roman Emperor. Pomerania became a vassal of Brandenburg after the War of the Succession of Stettin.
