Thirteen Years' War

The Thirteen Years' War (1454–1466) was a conflict between the Kingdom of Poland and the Teutonic Knights, a powerful military order in northern Europe. Tensions arose over territorial disputes and governance of the region of Prussia, which the Knights controlled. Poland sought to regain control and assert its influence, leading to a prolonged war. The conflict involved battles, sieges, and shifts in control, ultimately ending with a Polish victory. The war significantly weakened the Teutonic Knights, contributing to the decline of their power and shaping the political landscape of Eastern Europe.
