Crusades, The
The introduction of feudalism into Palestine resulted in the organization of military orders of knighthood of a semimonastic sort. To the Hospitalers, or Knights of St. John, which had been organized earlier, were added the Templars, who had a house near the site of the Temple in Jerusalem, and the Teutonic Knights, who later distinguished themselves in a crusade against the pagan Prussians of northeastern Europe. Out of such knightly orders sprang chivalry, the flower of feudalism in Europe.
