House of Pomerania
In 1464, the dispute escalated due to the death of Otto III, Duke of Pomerania: Otto III had died without issue, and left his partition of Pomerania, the Duchy of Pomerania-Stettin vacated. Both his relatives from the House of Pomerania and the Hohenzollern claimed succession. In the Treaty of Soldin (1466), the Pomeranian dukes and Brandenburgian electors settled for a scenario where the House of Pomerania would rule Pomerania-Stettin as a Brandenburgian fief.
