There were many other Orders of soldier-monks besides these two. The best known are the Teutonic Knights, who originated during the Third Crusade at the siege of Acre (1190) in an association of North German Crusaders for the care of the sick and wounded. The Knights of the German Hospital of St. Mary the Virgin at Jerusalem--for such was their full title--gained powerful influence in Palestine; their Order was confirmed by Pope Celestine III (1191-8), and in 1220 Honorius III gave them the same privileges as were enjoyed by the Hospitallers and Templars. Their organisation was similar to that of the older Orders. Their prosperity was chiefly due to the third Grand Master, Herman von Salza, the good genius of the Emperor Frederick II, and a great power in Europe. Under him the Order transferred itself to the shores of the Baltic, where it carried on a crusade against the heathen Prussians, and here it united in 1237 with another knightly Order, the Brethren of the Sword, which had been founded in 1202 by the Bishop of Livonia for similar work against the heathen inhabitants of that country. [Sidenote: Other military Orders.] The Knights of the Hospital of St. Thomas of Acre was a small English Order named after Thomas Becket and founded in the thirteenth century. They, together with those already mentioned as founded for work in Palestine, belonged to the Canons Regular. For convenience, however, mention should be made here of the great Spanish Orders which were affiliated to the Cistercian monks. These were founded in imitation of the Templars and Hospitallers for similar work against the Saracens of the Peninsula. The Order of Calatrava, founded by a Cistercian abbot when that city was threatened by the Saracens in 1158, and the Order of St. Julian, founded about the same time, which ultimately took its name from the captured fortress of Alcantara, were amenable to the complete monastic rule; while the Portuguese Order of Evora or Avisa, founded a few years later, was assimilated rather to the lay brethren of the Cistercians, and its members could marry and hold property. There was one of the Spanish Orders, however, which was not connected with the Cistercians. The Knights of St. James of Compostella originated in 1161 for the protection of pilgrims to the shrine of Compostella. Their rule was confirmed by Alexander III in 1175, and the Order of Santiago became the most famous of the military Orders in the Peninsula. [Sidenote: New Monastic Orders.]
