Editing Prussian Confederation (section)

==Thirteen Years' War==

In February 1454, the Prussian Confederation rose against the Teutonic Order's rule. [[Gabriel von Baysen]] and [[Johannes von Baysen]], now leading the confederation with the support of [[Jan de Jani]] and [[Mikołaj Szarlejski]], both of the [[Clan of Ostoja]], requested the protection of King [[Casimir IV Jagiellon]] of Poland, and the incorporation of the region to the Kingdom of Poland, to which the King agreed and signed an act of incorporation in [[Kraków]] in March 1454.{{sfn|Górski|1949|p=54}} They also asked for, and received, a guarantee of their continued city rights and privileges for the nobility. Delegates and officials of the Confederation pledged allegiance to the Polish King during the incorporation in Kraków,{{sfn|Górski|1949|pp=71–72}} and also in the following months.

The resulting [[Thirteen Years' War (1454–66)|Thirteen Years' War]] ended in the defeat of the Teutonic Order and the 1466 [[Second Peace of Thorn (1466)|Second Peace of Thorn]]. The Order renounced any claims to the territories of [[Gdańsk Pomerania|Gdańsk/Eastern Pomerania]] and [[Chełmno Land]], which were reintegrated with Poland,{{sfn|Górski|1949|pp=88–90, 206–207}} and the region of Elbląg and Malbork, and [[Warmia]], which were also recognized as part of Poland.{{sfn|Górski|1949|pp=91–92, 209–210}} These regions formed the new Polish province of [[Royal Prussia]], with some local rights of autonomy.
