House of Pomerania
The Brandenburg-Pomeranian conflict about whether the House of Pomerania had to take the Duchy of Pomerania as a fief from the Electors of Brandenburg or as an immediate fief of the Holy Roman Emperors was temporarily settled in 1493, when John Cicero of the Brandenburgian Hohenzollern, and Bogislaw X of the House of Pomerania, had concluded the Treaty of Pyritz. This treaty discarded the obligation of the Pomeranian dukes to take their duchy as a fief from the Hohenzollern, as ruled in the prior Treaties of Prenzlau (1472/1479), but granted the Hohenzollern the right of succession in case the House of Pomerania became extinct.
