         In the early 12th century, the Knights Templars and Hospitallers monks who are ill to transmit leprosy to the hospital of Saint Lazarus. Since the return of their own ranks was not possible, there came to a Lazarus order. The need to protect the hospital from attacks by bandits and Sarazena a possibility that the Knights, who fell ill leprosy, were not long in order to fight with the sword, has changed since 1120 purely nursing I like the knight of the military tasks. Military Lazariánov section, also called the Lazaritov consisted of knights, who were filled with the desire to die in battle rather than rot alive.
        The relationship between hospital (Lazars) and hospital (the Hospitals) on the one hand and on the other hand, the hospital and temple (Templars) is documented by various sources.
