On May 25, 1368, a compromise was negotiated in Anklam,[5] which was made a formal treaty on June 8, 1372 in Stargard,[6] and resulted in a partition of Pomerania-Wolgast.

Excepted was the land of Neustettin (Szczecinek), which was to be ruled by his brother Wartislaw V, and was integrated into Bogislaw's part-duchy only after his death in 1390.

Elisabeth would become Holy Roman Empress after her marriage with Charles IV, and Casimir was adopted by and designated heir of his grandfather.

[9] In 1390 however, after Polish King Władysław II Jagiełło had promised to hand part of the heritage of Casimir IV, Wartislaw VII's stepbrother, over to Wartislaw, the latter concluded an alliance with Poland and received the Polish castellany of Nakło and probably some adjacent areas as a fief in return, declaring himself a vassal of Jagiełło III in Pyzdry.

According to scholars such as Juliusz Bardach, Władysław Czapliński, Fenrych (1961),[15] Marceli Kosman, Tadeusz Ładogórski, Andrzej Nowakowski, Michał Sczaniecki and Kazimierz Ślaski, Wartislaw's oath was for all territory held by him and meant that Pomerania-Stolp itself become a Polish fief.

[18] With respect to the discourse in Polish historiography, Branig and Buchholz (1997) say that however the treaty is interpreted, it did not have any significance for the future.

[20] Eric however failed in his most ambitious plan, to make Bogislaw IX king of both the Kalmar Union and the Polish–Lithuanian Commonwealth.

Eric had to leave Denmark in 1449 and ruled Pomerania-Rügenwalde (Darłowo), a small partition of Pomerania-Stolp, until his death in 1459.

[22] Eric II of Pomerania-(Wolgast)-Stolp allied with the Polish king Casimir IV in his Thirteen Years' War against the Teutonic Knights.

[26] In the Treaty of Soldin of 1466, a compromise was negotiated: Wartislaw X and Eric II, the dukes of Pomerania, took over Pomerania-Stettin as a Brandenburgian fief.

During the confirmation of the Peace of Prenzlau in 1479, the border was finally settled north of Strasburg and Bogislaw had to take his possessions as a fief from Brandenburg.
