Battle of Pagastin was a medieval battle fought between the Teutonic Knights and Prussians in 1271 during the Great Prussian Uprising (1260–1274). Pagan Prussians rose against their conquerors, who tried to convert them to Christianity, after Lithuanians and Samogitians defeated the joint forces of the Teutonic Knights and the Livonian Order in the Battle of Durbe in 1260. The first years of the uprising were successful for the Prussians, but the Knights received reinforcements from Western Europe and were gaining the upper-hand in the conflict.
