The Knights of Rhodes--as they were called at the time--were the only real survivors of the militant Order of Chivalry. Two centuries earlier their great rivals, the Templars, had been dissolved, and a large part of their endowments handed over to the Hospitallers. The great secret of the long and enduring success of the Order of St. John was their capacity for adapting themselves to the changing needs of the times. The final expulsion of the Christians from Syria had left the Templars idle and helpless, and the loss of the outlets for their energy soon brought corruption and decay with the swift consequence of dissolution. All through the history of the great Orders we find the Kings of Europe on the lookout for a chance to seize their possessions: any excuse or pretext is used, sometimes most shamelessly. An Order of Knighthood that failed to perform the duties for which it was founded was soon overtaken by disaster. The Hospitallers had realised, as early as 1300, that their former rôle of mounted Knights fighting on land was gone for ever. From their seizure of Rhodes, in 1310, they became predominantly seamen, whose flag, with its eight-pointed cross, struck terror into every infidel heart. Nothing but a combination of Christian monarchs could cope with the superiority of the Turk on land: by sea he was still vulnerable. The Knights took up their new part with all their old energy and determination: it is but typical that henceforward we never hear of the "Knights" of Malta fighting as cavalry. After various adventures the fleet found itself united at Messina, whence it proceeded to Baiae. The election to the papacy of the Cardinal de' Medici--one of their own Order--as Clement VII., gave the Knights a powerful protector. He assigned Viterbo as a residence for the Order till a permanent home had been discovered. Villiers de L'Isle Adam, Grand Master of the Order, was faced with many difficulties. Remembering the fate of the Templars, he was afraid that the Order would disperse, and its present helpless condition was surely tending to disintegration. At this time the war between Charles V. and Francis I. was at its height, and the quarrel between France and Spain was reflected within the ranks of the Hospitallers. As the French and Spanish Knights formed the greater part of the members, the unity of the Order was threatened by the quarrels between them that arose out of national sentiment. The Reformation was rapidly spreading, and was likely to prove dangerous to the lands of the Order in Northern Europe, and various monarchs were meditating the seizure of the Hospitallers' estates now that the Order was temporarily without a justification for its existence.
