ABSTRACT
In 1454, the vast majority of Prussian burghers and knights rebelled against their sovereign, Grand Master Ludwig von Erlichshausen and the whole Teutonic Order. The Prussian estates submitted to the Polish crown under King Casimir the Jagiellonian. The conditions of the Second Thorn Peace Treaty were to be validated by the pope. This never happened, since the Roman curia treated this issue as a tool for exerting pressure on the Polish king in the struggle for the Bohemian throne. In 1474, Tüngen placed himself in the care of the king of the composite monarchy of Hungary and Croatia-Dalmatia, Matthias I Corvinus, who was engaged in a struggle with the sovereign of Poland over the Bohemian crown and Silesia. As early as the next year, 1496, further royal emissaries demanded the order's military assistance in a planned expedition against the Ottoman Turks. In his response, Johann von Tiefen did not evade the obligation of fighting the “unfaithful”.
