The Thirteen Years’ War also called the War of the Cities, was a conflict fought in 1454–66 between the Prussian Confederation, allied with the Crown of the Kingdom of Poland, and the State of the Teutonic Order.

The war began as an uprising by Prussian cities and local nobility to win independence from the Teutonic Knights. The Prussian Confederation asked Poland’s King Casimir IV Jagiellon for help and offered to incorporate Prussia into the Kingdom of Poland. The Thirteen Years’ War ended in the victory of the Prussian Confederation and Poland and in the Second Peace of Thorn (1466).
