Treaty of Pyzdry
The Treaty of Pyzdry was signed on 2 November 1390 between Władysław II Jagiełło, king of Poland and Wartislaw VII of Pomerania-Stolp. The treaty, signed in Pyzdry, contained an oath of vassalage of Wartislaw to Jagiełło, the obligation to support the latter in the Polish-Teutonic War, and mutual trade alleviations for Pomeranian and Polish merchants. Wartislaw VII, who with his brothers was allied with the Teutonic Order before, received the Polish castellany of Nakło and probably some adjacent areas as a fief.
Interpretation of the treaty
Since the treaty does not specify the oath of vassalage of Wartislaw VII to Jagiello, different interpretations of the treaty are offered by historians:- Gòrski, Labuda, Bardach, Fenrych and Czaplinski said the oath was for all territory held by Wartislaw VII, including Pomerania-Stolp;
- Mitkowski, Zientara and Jasienica said the oath was for the territory Waritislaw received as fiefs from Jagiełło ;
- Mielcarz said the oath was binding only Wartislaw himself, as a person, to Jagiełło;
- Gumowski said the document shows Wartislaw giving a general solemn promise of service.
