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.
