This is a list of the duchies and dukes of Pomerania.

Dukes of the Slavic Pomeranian tribes (All Pomerania)

The lands of Pomerania were firstly ruled by local tribes, who settled in Pomerania around the 10th and 11th centuries.

Non-dynastic

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.

Duchy of Pomerania

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.

Partitions of Pomerania

First partition 1155–1264

In 1155, Pomerania was divided in Pomerania-Szczecin and Pomerania-Demmin. In the struggle to shake off Polish and Danish claims to feudal overlordship, Pomerania approached the Holy Roman Empire. In 1181, while staying in the camp outside the walls of Lübeck, Emperor Frederick I Barbarossa recognised Bogislaw I as duke of S(c)lavia, as it was called in the document.^[1] However, three years later in the Battle in the Bay of Greifswald (1184) the Danish Canute VI forced Pomerania to accept him as liege lord.^[2] In 1190 the Land of Słupsk-Sławno separated itself from Szczecin. With the defeat of Denmark in the Battle of Bornhöved (1227) Pomerania shook off the Danish liege-lordship,^[3] except for the city of Szczecin which remained under Danish suzerainty until 1235.

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.

In 1227, Słupsk came to Eastern Pomerania (Pomerelia) within fragmented Poland, Sławno to Western Pomerania. In 1238 both became part of Pomerelia, ruled by the House of Sobiesław, and following the extinction of the line in 1294, both were directly reintegrated with Poland in accordance with the Treaty of Kępno. In 1317, the area became part of the Pomerania-Wolgast (Wołogoszcz), first as a pawn from Brandenburg, and definitively in 1347.

After Wartislaw III died heirless in 1264, Barnim I became sole duke of the whole duchy. After Barnim's death, the duchy was to be ruled by his sons Barnim II, Otto I and Bogislaw IV. The first years, Bogislaw, being the eldest, ruled in place of his too young brothers.

Second partition 1295–1368

In 1295, the Duchy of Pomerania was divided roughly by the Peene and Ina rivers, with the areas north of these rivers ruled by Bogislaw IV became Pomerania-Wolgast, whereas Otto I received Pomerania-Szczecin south of these rivers.

Third partition 1368–1376

In 1368, Pomerania-Wolgast was divided into a western part (German: Wolgast diesseits der Swine, including the name-giving residence in Wolgast) and an eastern part (German: Wolgast jenseits der Swine, in literature also called Pomerania-Stolp or Duchy of Słupsk after the residence in Słupsk (Stolp)), which came back under Polish suzerainty as a fief.

Fourth partition 1376/1377–1478 and Pomeranian immediacy

In 1376, the western part of Pomerania-Wolgast (German: Wolgast diesseits der Swine) was subdivided in a smaller western part sometimes named Pomerania-Barth (Bardo) after the residence in Barth, and an eastern part which included the residence in Wolgast. In the following year, the Duchy of Słupsk was divided into a western part which included Stargard and an eastern part which included the residence in Słupsk (Stolp).

In 1459, the eastern partitions of Pomerania-Wolgast around Stargard and Stolp ceased to exist. In 1478, after 200 years of partition, the duchy was reunited for a short period when all her parts were inherited by Bogislaw X. By the Treaty of Pyritz in 1493 Pomerania shook off the Marcher liege lordship and became again an immediate imperial estate, after new disputes finally confirmed by the Treaty of Grimnitz in 1529, both treaties provided Brandenburg succession in case the Pomeranian dukes would become extinct in the male line.

Fifth and sixth partitions 1531–1625

In 1531, Pomerania was partitioned into Pomerania-Stettin (Szczecin) and Pomerania-Wolgast. This time however, in contrast to the earlier partitions with the same names, Pomerania-Wolgast included the western, and Pomerania-Stettin the eastern parts of the duchy. In 1569, were created the duchies of -Barth (split off from -Wolgast) and -Rügenwalde (Darłowo) (split off from -Stettin).

Definitive reunification and annexation to Sweden

In 1625, Bogislaw XIV reunited all Pomerania under his rule. However, in 1637, Sweden hold western parts of Pomerania (Hither Pomerania), originally including Stettin, legalised by the Peace of Westphalia in 1648 (Swedish Pomerania, several times reduced in favour of Brandenburgian Pomerania). Between 1637 and 1657 Lauenburg-Bütow Land (Lębork and Bytów) were reintegrated directly to Poland as a reverted fief, thereafter passed to Brandenburg under Polish overlordship until the Partitions of Poland. In 1648, Brandenburg prevailed in the Peace of Westphalia with its claim only for eastern parts of Pomerania (Farther Pomerania), with the Brandenburg electors officially holding simultaneously the title of dukes of Pomerania until 1806 (end of the Empire and its enfeoffments), but de facto integrating their Pomerania into Brandenburg-Prussia, making it one of the provinces of Prussia in 1815, then including former Swedish Pomerania.

In 1215, the duchy was divided in other smaller duchies: Gdańsk, Białogarda, Lubiszewo and Świecie.
