The Order of Calatrava (, ) was one of the four Spanish military orders and the first military order founded in Castile, but the second to receive papal approval. The papal bull confirming the Order of Calatrava was given by Pope Alexander III on September 26, 1164. Most of the political and military power of the order had dissipated by the end of the 15th century, but the last dissolution of the order's property did not occur until 1838. Origins and foundation It was founded at Calatrava la Vieja in Castile, in the twelfth century by St. Raymond of Fitero, as a military branch of the Cistercian family. The etymology of the name of this military order, Calatrava, conveys the meaning: "fortress of Rabah". Rodrigo of Toledo describes the origins of the order: Calatrava is the Arabic name of a castle recovered from the Muslims, in 1147, by the King of Castile, Alfonso VII, called el Emperador. Located in what was then the southernmost border of Castile, this conquest was more difficult to keep than to make, especially at a time with neither standing armies nor garrisons were known. In part to correct this deficiency, the military orders such as Knights Templars were founded, where men could fulfill a vow of perpetual war against the Muslim. The Templars, however, were unable to hold Calatrava, and the king found further volunteer warriors when Raymond, Abbot of the Cistercian monastery of Fitero offered himself. This step is said to have been suggested to the abbot by Father Diego Velázquez, a simple monk, but one who had been a knight, and thus was well acquainted with military matters. Diego was inspired with the idea of employing the lay brothers of the abbey to defend Calatrava. These Cistercian lay brothers--at that time a recent innovation in monastic life--not being in Holy orders, were variously employed in manual trades such as those of tending herds, construction, farm labor, or husbandry. Diego recommended that they become soldiers of the Cross. Thus a new order was created in 1157. Motivated by the desire for religious and pecuniary rewards, these brethren were eager to take the offensive against the Moors. When the Abbot Raymond died (1163), a certain Don García started to lead them in battle as their first grand master. At the same time, the choir monks, not without protest, left Calatrava to live under an abbot
