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 (Duchy of Słupsk). 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.
