Prussian uprisingsThe Prussian uprisings were two major and three smaller uprisings by the Old Prussians, one of the Baltic tribes, against the Teutonic Knights that took place in the 13th century during the Prussian Crusade. The crusading military order, supported by the Popes and Christian Europe, sought to conquer and convert the pagan Prussians. In the first ten years of the crusade, five of the seven major Prussian clans fell under the control of the less numerous Teutonic Knights. However, the Prussians rose against their conquerors on five occasions.
Prussian CrusadeThe Prussian Crusade was a series of 13th-century campaigns of Roman Catholic crusaders, primarily led by the Teutonic Knights, to Christianize under duress the pagan Old Prussians. Invited after earlier unsuccessful expeditions against the Prussians by Christian Polish kings, the Teutonic Knights began campaigning against the Prussians, Lithuanians and Samogitians in 1230.
