At the onset of the crusade, the intended destination was Egypt, as the Christians and Muslims were under a truce at the time. An agreement was made between the French Crusaders and the Venetians. The Venetians would supply vessels and supplies for the crusaders and in return the crusaders would pay 85,000 marks (£200,000). Innocent gave his approval of this agreement under two conditions: a representative of the pope must accompany the crusade, and the attack on any other Christians was strictly forbidden. The French failed to raise sufficient funds for payment of the Venetians. As a result, the Crusaders diverted the crusade to the Christian city of Zara at the will of the Venetians, to subsidize the debt. This diversion was adopted without the consent of Innocent III, who threatened excommunication to any who took part in the attack. A majority of the French ignored the threat and attacked Zara, and were excommunicated by Innocent III, but soon were forgiven so as to continue the crusade. A second diversion then occurred when the crusaders decided to conquer Constantinople, the capital of the Byzantine Empire, at the behest of the exiled Byzantine prince Alexios IV. This diversion was taken without any knowledge by Innocent III, and he did not learn of it until after the city had been captured.
