The Second Peace of Thorn of 1466,…
October 1466 CE
The Second Peace of Thorn of 1466, a peace treaty signed in the Hanseatic city of Thorn (Toruń) on October 9, 1466 between the Polish king on one side, and the Teutonic Knights on the other, concludes the Thirteen Years' War that had begun in February 1454 with the revolt of the Prussian Confederation, led by the cities of Danzig (Gdańsk), Elbing (Elbląg), Kulm (Chełmno) and Thorn, and the Prussian gentry against the rule of the Teutonic Knights in the Monastic state.
Both sides agree to seek confirmation from Pope Paul II and Holy Roman Emperor Frederick III, but the Polish side stress (and the Teutonic side agrees) that this confirmation will not be needed for validation of the treaty.
In the treaty, the Teutonic Order cedes the territories of Pomerelia (Eastern Pomerania) with Danzig, Chełmno Land with Kulm and Thorn, the mouth of the Vistula with Elbing and Marienburg (Malbork), and the Bishopric of Warmia (Ermland) with Allenstein (Olsztyn).
The Order also acknowledges the rights of the Polish Crown for Prussia's western half, subsequently known as Polish or Royal Prussia.
Formerly limited to Germans, the order is forced to accept Polish members.
As a consequence of the treaty, Warmia becomes an autonomous region ruled by bishop of Warmia.
Eastern Prussia, later called the Duchy of Prussia, will remain with the Teutonic Order until 1525; the Grand Master is supposed to swear a personal oath (the Prussian homage) to the king of Poland and to furnish him with military.
In order to avoid giving the oath, the new Grand Masters will simply make it their practice not to visit Prussia.
