=== Thirteen Years' War ===
After the [[Prussian Confederation]] pledged allegiance to Casimir on 6 March 1454, the [[Thirteen Years' War (1454–66)|Thirteen Years' War]] ("War of the Cities") began. King [[Casimir IV Jagiellon]] appointed Bażyński as the first war-time governor of Royal Prussia. On 28 May 1454, the king took an oath of allegiance from the citizens of Chełmno Land, including Toruń (Thorn) in Toruń,{{sfn|Górski|1949|pp=76–77}} and in June a similar oath from the citizens of Elbląg (Elbing) and Królewiec (Königsberg) was taken.<ref name="KirykRys">F.

The war also included major cities from the eastern part of the Order's lands, such as [[Kneiphof]], later a part of Königsberg. Though the Knights were victorious at the [[Battle of Chojnice (1454)|Battle of Chojnice]] in 1454, they were not able to finance more knights in order to reconquer the castles occupied by the insurgents. Thirteen years of attrition warfare ended in October 1466 with the Second Peace of Thorn (1466), which provided for the Order's cession to the Polish Crown of its rights over Pomerelia, and the western half of [[Prussia (region)|Prussia]], including the districts of Elbląg and Malbork (Marienburg).
