A great part of his army was now scattered, and the remnant was led by his son Frederick of Swabia against Ptolemais. At that point soon after landed =Philip Augustus= and =Richard Cœur de Lion= of England, who after his father’s death put himself at the head of an English crusading army and had conquered Cyprus on the way. Ptolemais (Acre) was taken in A.D. 1191. But the jealousies of the princes interfered with their success. Frederick had already fallen, and Philip Augustus under pretence of sickness returned to France; Richard gained a brilliant victory over Saladin, took Joppa and Ascalon, and was on the eve of marching against Jerusalem when news reached him that his brother John had assumed the throne of England, and that Philip Augustus also was entertaining schemes of conquest. Once again Richard won a great victory before Joppa, and Saladin, admiring his unexampled bravery, concluded with him now, in A.D. 1192, a three years’ truce, giving most favourable terms to the pilgrims. The strip along the coast from Joppa to Acre continued under the rule of Richard’s nephew, Henry of Champagne. But Richard was seized on his return journey and cast into prison by Leopold of Austria, whose standard he had grossly insulted before Ptolemais, and for two years he remained a prisoner. After his release he was prevented from thinking of a renewal of the crusade by a war with France, in which he met his death in A.D. 1199.[269] § 94.4. =The Fourth Crusade, A.D. 1217.=--Innocent III. summoned Christendom anew to a holy war. The kings, engaged in their own affairs, gave no heed to the call. But the violent penitential preacher, Fulco of Neuilly, prevailed upon the French nobles to collect a considerable crusading army, which, however, instead of proceeding against the Saracens, was used by the Venetian Doge, Dandolo, in payment of transport, for conquering Zaras in Dalmatia, and then by a Byzantine prince for a campaign against Constantinople, where Baldwin of Flanders founded a =Latin Empire=, A.D. 1204-1261. The pope put the doge and the crusaders under excommunication on account of the taking of Zaras, and the campaign against Constantinople was most decidedly disapproved. Their unexpected success, however, turned away his anger. He boasted that at last Israel, after destroying the golden calves at Dan and Bethel, was again united to Judah, and in Rome bestowed the pallium upon the first Latin patriarch of Constantinople.--The =Children’s Crusade=, which in A.D. 1212 snatched from their parents in France and Germany 30,000 boys and girls, had a most tragic end. Many died before passing from Europe of famine and fatigue; the rest fell into the hands of unprincipled men, who sold them as slaves in Egypt.--King =Andrew II. of Hungary=, urged by Honorius III., led a new crusading army to the Holy Land in A.D. 1217, and won some
