Book excerpt: The Hospitallers were a religious order, founded in Jerusalem by 1099, devoted to nursing and to fighting the infidel. With their fellow knights, the Templars, they played a heroic part in the defence of the Holy Land, defending great castles, such as Krak des Chevaliers, while at the same time providing exemplary nursing care for the poor. Hospitallers is an illustrated history, by a leading historian of the crusades, of this remarkable body, the heir of which is the Order of St. John.
