List of Pomeranian duchies and dukes

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.

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.

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.

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.

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.

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).

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.

(Note: Here the numbering of the dukes is the same for all duchies, as all were titled Dukes of Pomerania, despite the different parts of land or particular numbering of the rulers. The dukes are numbered by the year of their succession.)

After the end of the regency of Agnes, the four rulers divided possessions: The sons of Barnim kept Wolgast; the sons of Warcislaus received Barth. However, as the sons of Warcislaus left no children, their possessions returned to the sons of Barnim VI.
Barnim VII the Older		1390	1425–1450	22 September 1450	Pomerania-Wolgast	Unmarried

Regency of Maria of Masovia (1446-1449)							Son of Warcislaus VII and original heir of Stolp in 1394, was under regency of his cousin's widow, Maria.

Sophie		1435	1459–1474	24 August 1497	Pomerania-Stolp	1451 twelve children	Daughter of Bogislaw IX and heir of Eric I. Despite her husband had inherited the duchy itself, the fact that she only renounced her rights to Pomerania in 1474 is possibly a sign of a co-rulership between the spouses.
Eric II		between 1418 and 1425	1457–1474	5 July 1474	Pomerania-Wolgast		Children of Warcislaus IX, divided the land. In 1464 Eric absorbed Stettin, but it was only with Warcislaus' death that Pomerania was reunited, already under Eric's son, Boguslaus.

Divided the land in 1569: Ernest Louis kept Wolgast, John Frederick received Stettin, Bogislaw received Barth and Neuenkamp (later Franzburg), and Barnim received Rügenwalde. In 1592 Bogislaw became tutor of his nephew Philip Julius. In 1600 after the death of John Frederick without children, the land was inherited by Barnim, who reunited it with Rügenwalde. At the latter's death in 1603 also with no descendants, Bogislaw received the land and united it with Barth, but he gave Rügenwalde to one of his sons, and gave Barth and Neuenkamp to Philip Julius.

George II		30 January 1582	1606–1617	27 March 1617	Pomerania-Rügenwalde	Unmarried	Children of Bogislaw XI, divided the land. As they had no descendants, they inherited each other's lands and, lastly, it entirety ended up inherited by their younger brother Bogislaw.

Bogislaw XIV [XII] the Sociable		31 March 1580	1617–1620	10 March 1637	Pomerania-Rügenwalde	Elisabeth of Schleswig-Holstein-Sonderburg 1615 no children	Younger son of Bogislaw XI, inherited the possessions of all his brothers and reunited Pomerania, but he also didn't have any children. At his death, Pomerania was annexed by the Kingdom of Sweden. But,the latest studies confirm the opinion that formally the titles of Bogislav XIV continued to be inherited by the descendants of Bogislav II through a younger hereditary line, which leads us to the count family of Hubytsky from Ukraine, which exists to this day.
