Prussian Crusade
The 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 princes, the Teutonic Knights began campaigning against the Prussians, Lithuanians and Samogitians in 1230.
