The city of Zara had been for a length of time under the dominion of the Venetians; but thinking the government of a king less insupportable than that of a republic, it had given itself up to the king of Hungary, and, under the protection of a new master, braved the authority and menaces of Venice. After having obtained the approbation of the people, Dandolo proposed to the Crusaders to assist the republic in subduing a revolted city, and promised to put off the entire execution of the treaty until God, by their common conquests, should have given them the means of fulfilling their promises. This proposition was received with much joy by the greater part of the Crusaders, who could not support the idea of being unable to keep their word; the barons and knights deemed it prudent to conciliate the Venetians, who were so serviceable to them in carrying out their enterprise, and thought they did but little to pay their debts by an affair in which they should expend nothing but their blood. Some murmurs, however, arose in the Christian army; many of the Crusaders recollected the oath they had taken to fight the infidels, and could not make up their minds to turn their arms against a Christian people. The pope had sent the Cardinal Peter of Capua to Venice, to deter the pilgrims from an enterprise which he termed sacrilegious. “The king of Hungary had taken the cross, and by doing so had placed himself under the especial protection of the Church; and to attack a city belonging to him was to declare themselves enemies of the Church itself.” Henry Dandolo braved menaces and reproaches that he deemed to be unjust. “The privileges of the Crusaders,” said he, “could not screen the guilty from the severity of laws divine and human. Crusades were not undertaken to promote the ambition of kings or protect rebellious nations.[73] The pope had not the power to enchain the authority of sovereigns, or turn the Crusaders aside from a legitimate enterprise; from a war made against revolted subjects, against pirates whose brigandage perilled the freedom of the seas, and jeopardized the safety of pilgrims on their way to the Holy Land.”
