Partitions of the Duchy of Pomerania

None of the partitions had a hereditary character,[2][3] the members of the House of Pomerania inherited the duchy in common.

[2] The only exception was made 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, while Pomerania-Wolgast remained under formal Brandenburgian overlordship.

[4][5] However, already in 1348, German king and later emperor Charles IV again granted the Duchy of Pomerania as a whole and the Principality of Rügen as a fief to the dukes of both Pomerania-Stettin and Pomerania-Wolgast, nullifying Brandenburg's claims by granting Imperial immediacy.

[9][12] In 1478, Pomerania-Barth was merged back in, temporarily ending the internal division.

[9][12] In 1532, the duchy was partitioned in a Pomerania-Stettin and a Pomerania-Wolgast of significantly different shape as the earlier divisions of the same names.
