But meanwhile a still greater temptation presented itself to attract the crusaders out of their straight course. For a long time past the Empire of the East had been distracted by civil wars. At the time when the crusaders set sail from Venice the Emperor Isaac had been dethroned and blinded by his brother Alexis, who had seized the power. But Isaac’s son, the younger Alexis, had succeeded in eluding his uncle’s vigilance, and had escaped from Constantinople. He had visited Rome with the intention of obtaining assistance from Pope Innocent

III., but only to find that his purpose had been forestalled by his uncle, the reigning Emperor. The latter, fearing the Pope’s interference, had already sent an embassy to him with instructions to beguile him with promises of a reconciliation between the Greek and Latin Churches. As this reconciliation, or submission, was the principal inducement which the younger Alexis had to offer in return for help, the Pope considered that it would be wiser to treat with the uncle, who was in possession, rather than with the nephew who was a fugitive. Deceived in his hopes, the younger Alexis proceeded to Germany, to the court of King Philip of Swabia, who had set himself up as Emperor against Otho IV., and had married a sister of the young Prince. It is not clear whether it was Philip himself who suggested to Alexis the possibility of attracting the crusaders to Constantinople, but he appears to have recommended the plan and to have strongly urged the Venetians to agree to it. At all events Alexis

now proceeded to Zara and soon interested the aged Dandolo in his cause. He made great promises if the crusaders would help him to get back the throne; he would bear the whole expenses of the crusade for one year; he would divide amongst the crusaders a sum of two hundred thousand silver marks; he would guarantee for all future time that five hundred knights should be supported by the Greek Empire in the Holy Land to guard it from the attacks of unbelievers; and finally, he promised to bring the Eastern Church back to the spiritual dominion of the popes. These magnificent offers on the one hand, and the moving picture which, on the other, he drew of his father Isaac’s sufferings, produced a profound impression upon his hearers, and especially, perhaps, upon those who had already been in Constantinople and had formed an opinion as to the value of such a prize. In the eyes of the Venetians, too, there was even another object to be accomplished, namely, the destruction of the power of Pisa and of her commerce in the East.

Rom. ii. 162.

It was in vain that the Pope, who wished to manage matters himself, and who was more than half pledged to the usurper of the throne, raised his voice in threats and protestations; it was in vain that he insisted on the wretched condition of the Christians in Palestine and the extremities to which they were reduced, pointing out that their welfare was to be considered rather than a blind prisoner’s claims to the throne from which he had been ousted, no matter how unjustly. Nothing that the Pope could say had the slightest effect upon men whose conscience agreed to an act of justice in which their ruling passion for gain anticipated an opportunity for almost unbounded plunder. Those who feared to displease the Pope, or were terrified by the menace of excommunication, were told that they were free to leave the ranks if they chose. A few French knights took advantage of this alternative and left the army; amongst these was Simon de Montfort. But the principal French nobles espoused the cause of the younger Alexis, including Boniface of Montferrat, Baldwin of Flanders, Louis of Blois, and Hugh the Count of Saint Paul. These and the great majority, with their followers, threw in their lot with Enrico Dandolo, and looked on with indifference when the Pope’s cardinal legates left the crusade and proceeded to the East by themselves.

Sismondi considers that the subsequent attitude of Venice towards the Holy See throughout her history had its origin at this time; for when, before the expedition sailed, Cardinal San Marcello arrived in Venice, as the Pope’s legate, to take command of the crusading fleet, he was informed that if he shipped as a Christian preacher he should be treated with the highest honours, but that if he came with the slightest idea of giving orders he could not be allowed on board; whereupon, having thoroughly understood the situation, he returned to Rome.

As the fleet proceeded eastwards it was very naturally obliged to put in at a number of Greek harbours, not only to obtain provisions, but because it was absolutely necessary to land the crusaders’ horses from time to time for exercise; and when we consider the conditions of navigation and the dimensions of vessels in those days, we are surprised that such a body of cavalry could have been successfully transported at all from the Venetian islands to the very walls of Constantinople. It was generally considered at that period that Constantinople shared the dominion of the sea with Venice, but it appears that the Emperor’s brother-in-law, who was high admiral of the fleet, had deliberately sold for
