Zara's value = The Venetians had lost the port in 1186, and it was a valuable stop-off point on the journey to Outremer; it also supplied the Venetians with Dalmation oak in which they built their ships
Risk of Violence = After the 51,000 marks were paid, they still owed money, so if the crusade was halted, the troops in Venice may have rebelled
Salvation = Dandolo was old but he had taken the crusader vow, so he needed to aid the crusade to have the plenaryindulgence granted
Division in the Crusading Force when attacking Zara
Prior to the depature, Boniface and Peter had visited Rome to inform the pope - Boniface did not return until Zara had fallen and Peter not until the capture of Constantinople - the forces had lost their commander in chief and papal authority
The papal letter that threatened the crusaders was used by Abbot Guy of Vaux-de-Cernay and Simon of Montfort to quell enthusiasm of the attack on Zara
How did the siege of Zara weaken the crusade
It delayed the journey to Alexandria as it was too late in the year to embark on a long voyage
It led to several nobles to abandon the crusade and question the actions taken against papal command
The French contingent was granted an oath which took them out of excommunication; however, the Venetians did not take this oath
There was now a gap between allies - The French and Crusaders wanted to reach Alexandria and Jerusalem, while the Venetians wanted to secure commercial power
