List of Pomeranian duchies and dukes
This is a list of the duchies and dukes of Pomerania.
The lands of Pomerania were firstly ruled by local tribes, who settled in Pomerania around the 10th and 11th centuries.
In 1106, Pomerania is divided by his two older sons: Wartislaw, who founded the House of Pomerania and the Duchy of Pomerania, and Świętopełk I. After Swietopelk's death, his lands were occupied by the Saxon prince Lothar of Supplinburg. In 1155, the lands regained independence under Sobieslaw I, who founded the dynasty of the Samborides, and the Duchy of Pomerelia.
The Duchy resulted from the partition of Świętobor, Duke of Pomerania, in which his son Wartislaw inherited the lands that would become in fact known as Pomerania.
In 1155, Pomerania was divided in Pomerania-Stettin and Pomerania-Demmin. In 1190 the Land of Słupsk-Sławno separated itself from -Stettin.
In 1231 Emperor Frederick II granted the immediate liege lordship over Pomerania to the Margrave of Brandenburg, who enforced this claim by the Treaties of Kremmen (1236) and of Landin (1250). Thus Pomerania had become a fief of Brandenburg, thus an only mediate (indirect) subfief of the Empire, with Brandenburg itself being an immediate imperial fief.
