The Duchy of Pomerania was partitioned several times to satisfy the claims of the male members of the ruling House of Pomerania dynasty. The partitions were named after the ducal residences: Pomerania-Barth, -Demmin, -Rügenwalde, -Stettin, -Stolp, and -Wolgast. None of the partitions had a hereditary character, the members of the House of Pomerania inherited the duchy in common. The duchy thus continued to exist as a whole despite its division.
