Strategic Narrative Overview
Pope Innocent III sent explicit letters forbidding the attack on Zadar and threatening those who proceeded with excommunication. A portion of the crusading army refused to participate, but the majority, bound by their debt to Venice, joined the assault beginning 10 November 1202. The city's defenders held out for two weeks before Zadar fell on 24 November. Venetian and crusader forces then sacked the city together.
01 / The Origins
The Fourth Crusade's leaders contracted Venice to provide sea transport to the Holy Land, but the assembled crusading force was far smaller than expected and could not meet the agreed payment. Venice, long contesting control of Zadar with the Kingdom of Croatia and Dalmatia and Hungary, made its continued support conditional on the crusaders helping to retake the city. Despite the Hungarian king Emeric having taken the crusader's cross, the Venetians pressed their demand.
03 / The Outcome
After the fall of Zadar, the combined force wintered in the captured city. Pope Innocent III subsequently excommunicated the participants, though he later lifted the sentence from the crusaders while maintaining it against Venice. The stopover in Zadar set the stage for further diversion of the Fourth Crusade, which ultimately redirected toward Constantinople rather than the Holy Land.
