This all seemed wonderfully efficient. Yet, despite the verve and assurance of Innocent’s vision, all his multifarious efforts elicited only a muted response: the anticipated hordes of enthusiastic warriors did not enlist (although many of the poor took the cross); the donation chests strewn across the West failed to fill. Innocent’s first crusade encyclical had called for an expedition to start in March 1199, but that date soon came and went without any sign of action, and eventually a second call was made in December 1199. By this time, control of what would become the Fourth Crusade was already slipping through his fingers.

In fact, Innocent’s conception of crusading was fundamentally flawed. Absolutist in tone, it made no provision for interactive collaboration between the Church and the secular leaders of lay society. The pope imagined that he would simply bend the kings and lords of Latin Christendom to his will, as mere tools of God’s purpose. But this proved to be entirely unrealistic. From the First Crusade onwards, Europe’s lay nobles had been utterly essential to the crusading movement. It was their febrile enthusiasm that could spark expanding waves of recruitment through the social networks of kinship and vassalage, and their military leadership that could direct the holy war. Innocent had certainly hoped to enrol knights, lords and even kings in his crusade, but only as obedient pawns, not equals or allies.

Historians used to suggest that Innocent deliberately limited the degree of royal involvement in the crusade, but this is not entirely true. To begin with, at least, he sought to broker a peace deal between Angevin England and Capetian France, and made some attempt at convincing King Richard I to take the cross. But when the Lionheart died in 1199, these nebulous plans somehow still to incorporate the Latin monarchy within the ‘papal crusade’ evaporated. After Richard’s demise, his brother John was too busy battling to assume control of England and the Angevin realm to consider crusading. King Philip II Augustus of France equally made it clear that, until the Angevin succession was resolved, he would not leave Europe. And the ongoing power struggle in Germany precluded any direct Hohenstaufen participation. But even when it became obvious that there would be no crown involvement from these three realms, Innocent did not attempt to consult or recruit secular leaders from the upper aristocracy. He probably believed that the members of this class would flock to his cause of their own natural volition, eager to serve at his beck and call–but he was wrong, and this lapse of judgement would have tragic consequences for Christendom.³

THE FOURTH CRUSADE

Contrary to Pope Innocent III’s hopes and expectations, the Fourth Crusade was shaped largely by the laity, being subject to secular leadership and the influence of worldly concerns. Real enthusiasm and widespread recruitment for the expedition among Europe’s elite warriors only took hold after two prominent northern French lords–Count Thibaut III of Champagne and his cousin Louis, count of Blois–took the cross at a knightly tournament at Écry (just north of Rheims) in late November 1199. In February 1200 Count Baldwin of Flanders followed suit. All three men were drawn from the highest echelon of the Latin nobility, with connections to the royal houses of England and France. Each possessed an inestimable ‘crusade pedigree’ as multiple generations of their respective families had fought in the war for the Holy Land. Yet, although they appear to have been aware of Fulk of Neuilly’s preaching of the crusade, there is no evidence to suggest that they were directly contacted or encouraged to enlist by any representative of the pope. Certainly, like most earlier crusaders, they regarded themselves as answering a call to arms issued and sanctioned by the papacy–but they do not seem to have perceived any special need to work alongside Rome in planning or executing their expedition. This resulted in a worrying disjuncture between their outlook and the idealised notions entertained by Innocent III.

Diversions to disaster

In April 1201, a group of crusader envoys–representing Thibaut, Louis and Baldwin–negotiated an ill-fated treaty with the Italian naval and commercial superpower of Venice. The agreement called for the construction of a vast fleet to transport 33,500 crusaders and 4,500 horses across the Mediterranean in return for the payment of 85,000 silver marks. This massive commission prompted the Venetians to call a temporary halt to their wider trading interests, putting all their energy into building the requisite number of ships in record time.

This scheme was unsound from its inception. The notion of using seaborne transport to reach the Holy Land had been popularised during the Third Crusade, with both the English and French contingents sailing to war. The problem was that sea travel was expensive and, in comparison to an overland march, required a massive initial outlay of hard cash. The fleets used by the Third Crusaders had to be underwritten by royal treasuries, and even then the requisite funds were not easily amassed. Lacking crown involvement or support, the Fourth Crusade inevitably struggled to foot the bill owed to Venice. The 1201 treaty was also predicated on the unrealistic assumption that every Latin who took the cross would agree to travel from the same port on a specified date, even though there was no precedent for this type of systematic departure and no commitment to embark from Venice was included in the crusading vow. The plan might just have worked had the secular leadership coordinated their efforts with the papacy to orchestrate a general muster–as it was, Innocent does not even seem to have been consulted about the deal with Venice. Realising that he was fast losing any semblance of control over the expedition, the pope grudgingly confirmed the treaty. From this point onwards, Innocent gradually found himself trapped between conflicting impulses: the desire to bring the crusade to heel by withdrawing his support; and the lingering hope that the campaign would still somehow find a way to enact God’s will.

The Fourth Crusade’s prospects were dealt a grievous blow in May 1201 when Thibaut of Champagne, though barely twenty years old, fell ill and died. Overall leadership passed to the north Italian nobleman Boniface of Montferrat–who, through his brothers William and Conrad, possessed his own notable ‘crusade pedigree’–but Thibaut’s demise nonetheless weakened recruitment in northern France. When the crusaders began to congregate at Venice from around June 1202 onwards, it quickly became obvious that there was a problem. By midsummer 1202, only around 13,000 troops had arrived. Far fewer Franks had taken the cross than predicted, and, of those who had enrolled, many chose to take ship to the East from other ports like Marseilles.

Even scraping together every available ounce of money, the crusade leaders were thus left with a massive financial shortfall. The Venetians had carried out their part of the bargain–the grand armada was ready–but they were still owed 34,000 marks. The expedition was saved from immediate collapse by the intervention of Venice’s venerable leader, or doge, Enrico Dandalo. A wizened, half-blind octogenarian whose spirited character and unbounded energy belied his age, Dandalo possessed a shrewd appreciation of warfare and politics, and was driven by an absolute determination to further Venetian interests. He now offered to commute the crusaders’ debt and to commit his own troops to join the Levantine war, so long as the crusade first helped Venice to defeat its enemies. In agreeing to this deal, the Fourth Crusade drifted from the path to the Holy Land.
