The Houses of Hohenzollern and Pomerania held conflicting claims over the Duchy of Pomerania. Brandenburg claimed feudal overlordship over the duchy, while Pomerania disputed this status. These unresolved tensions made a formal diplomatic settlement necessary to clarify the duchy's legal standing and future succession.
On 26 March 1493 in Pyritz, John Cicero of Brandenburg renounced his electorate's claim to hold Pomerania as a Brandenburg fief. Two days later in Königsberg, Bogislaw X reciprocated by acknowledging Brandenburg's right to succeed to Pomerania should his own dynasty become extinct, producing a bilateral accord.
The treaty resolved a long-standing dynastic dispute and was considered the defining achievement of Bogislaw X's foreign policy. It established a framework for future relations between the two houses, later confirmed and amended by the Treaty of Grimnitz in 1529, which provided a final settlement between Brandenburg and Pomerania.

Brandenburg renounced feudal claims over Pomerania; Pomerania acknowledged Hohenzollern succession rights if the Pomeranian dynasty became extinct.
Brandenburg claimed feudal overlordship of the Duchy of Pomerania, creating contested sovereignty.
