[2] In turn, Bogislaw X, Duke of Pomerania acknowledged Brandenburgian succession in his duchy in case of the extinction of his dynasty on 28 March in Königsberg (now Kaliningrad).

[7] The war was temporarily ended with the Treaty of Prenzlau (1472), when the House of Pomerania had to accept Brandenburgian overlordship and succession as well as territorial losses, but flared up again in 1477.

[2] Margarethe, a daughter of Frederick II, Elector of Brandenburg and married to Bogislaw X since 1477, sided with her husband in the feud despite maintaining good relations to her cousin, John Cicero.

[11] Bogislaw X accused her that she had manipulated her body to prevent conception, so the Pomeranian duchy would fall to Brandenburg according to the treaties of Prenzlau.

[15] In the following, Bogislaw X frequently contacted Maximilian I, Holy Roman Emperor to personally receive the Duchy of Pomerania as a fief.

[16] However, Bogislaw X was then integrated in the Upper Saxon Circle and awarded a seat and a vote in the Imperial Diet, which he seized despite Brandenburgian protests in Nuremberg in 1522.

[17] In 1529, the Treaty of Grimnitz finally settled the conflict, confirming and amending the treaty of Pyritz:[3] In Grimnitz, Pomerania was confirmed as an immediate imperial fief, yet the Electors of Brandenburg had to be present at every formal investiture and were allowed to touch the Pomeranian flag during the process, furthermore they were allowed to entitle themselves as dukes of Pomerania with the exception of cases when both the Pomeranian dukes and the Brandenburgian electors were present.
