Like the Templars and Hospitallers, a religious order of knighthood which arose during the period of the Crusades, originally for the purpose of tending wounded crusaders; subsequently became military in character, and besides the care of the sick and wounded included among its objects aggressive warfare upon the heathen; was organised much in the same way as the Templars, and like them acquired extensive territorial possessions; during the 14th and 15th centuries were constantly at war with the heathen Wends and Lithuanians, but the conversion of these to Christianity and several defeats destroyed both the prestige and usefulness of the knights, and the order thenceforth began to decline. As a secularised, land-owning order the knighthood lasted till 1809, when it was entirely suppressed in Germany by Napoleon; but branches still exist in the Netherlands and in Austria, where care for the wounded in war has been resumed.
