War of the Priests
Olsztyn, PolandThe War of the Priests was a conflict in the Polish province of Warmia between the King of Poland Casimir IV and Nicolaus von Tüngen, the new bishop of Warmia chosen – without the king's approval – by the Warmian chapter. The latter was supported by the Teutonic Knights, by this point vassals of Poland, who were seeking a revision of the recently signed Second Peace of Toruń.
