Unlike their sometime rivals the Templars, the Order of St John of the Hospital of Jerusalem (or the Hospitallers as they are better known) was not created as a result of the First Crusade in 1099: rather, it was probably established by a group of Italian merchants from Amalfi in the mid-11th century. However, as a consequence of the crusading movement, the Hospitallers became recognised experts in the military capabilities of opposing Islamic armies. This book, the first of two to examine the lifestyle, experiences and military role of the Hospitaller knight, covers the period from the foundation of the order to the invasion of Rhodes in 1306.

Having campaigned on land during their early existence, the Hospitallers fought mainly at sea from the turn of the 14th century. The emphasis was now on small-scale operations, rather than the crusading invasion that had so often come to grief. Having conquered Rhodes, the Order fortified it and transferred there in 1309. A period of on-off warfare with the Mamluks became full-blown conflict with the Ottomans, who captured Rhodes in 1522, forcing the Hospitallers to transfer to Malta. This book, the second of two, takes a close look at the men who lived and died for the Hospitaller cause in this key period, and the political and economic role that the Order played within the Christian empire.
