Career
The reign of Bogislaw was influenced by the contemporary Polish-Teutonic Wars between his eastern neighbors, Poland and Teutonic Prussia. The Pomeranian dukes, whose territory was the only land route to Teutonic Prussia not controlled by Poland, exploited this conflict by frequently changing sides. Late in 1388, the dukes of Pomerania-Stolp left an alliance and sided with Poland, who had promised to partially respect their claims as Casimir III"s heirs.
Bogislaw VIII, Barnim V and Wartislaw VII reacted by siding with Polish king Jogaila and negotiating mutual trade alleviations.
Swantibor III and Bogislaw VII of Pomerania-Stettin changed sides in 1395 and allied with the knights in return for economic aid. However, in 1397 Barnim concluded an alliance with Poland, married Vytautas" niece Hedwig and entered into Jogaila"s service in 1401 until he died in 1402 or 1404.
When the knights lost the Battle of Tannenberg in 1410, Bogislaw changed sides again and allied with Poland in return for the Bütow, Schlochau, Preußisch-Friedland, Baldenburg, Hammerstein and Schivelbein areas, which Poland had gained from Teutonic Prussia before. This was cancelled by the First Peace of Thorn in 1411.
Bogislaw had two children, Bogislaw IX and Adelheid of Pomerania (1410–after 1444/45) who married Bernard II, Duke of Saxe-Lauenburg in 1429.
