The leadership may also have possessed another trump card. The process of reaching decisions in the crusader army followed an almost constitutional pattern. Whatever the high command of perhaps a dozen or so magnates decided required the approval of the wider council of barons. Counsel and consent lay at the heart of all western European political structures of the period. The crusade army, a political society in microcosm, formed no exception. Some major decisions were put to an even wider body of all self-funding
The reasons why the leadership were so eager to endorse the diversions to Zara and then Constantinople were pragmatic, ambitious and opportunistic: to secure the expedition’s funding and material resources on the one hand and, on the other, to attempt to realign the politics of the eastern Mediterranean in favour of Rome, Outremer and the crusade. They were fully aware of the moral difficulties, even without the words of Simon of Montfort and the abbot of Vaux ringing in their ears. The apparent contradiction of crusaders fighting Christians – ‘detestable and unlawful’ according to Gunther of Pairis18 – was balanced by claims of justice, recorded by a number of witnesses: justice for past Venetian wrongs at the hands of Zarans; justice for the wronged Alexius Angelus. The Greek claimant provided what Dandolo was recorded as seeking for an attack on Byzantium, a ‘raisnable acoison’, a reasonable cause or good excuse.19 Writing to the crusader army in January or February 1203, Innocent III, while forbidding the crusaders from ‘invading [or] violating the lands of Christians in any manner’, entered a caveat: ‘unless, perchance they wickedly impede your journey or another just or necessary cause’, in which cause an exception could be made but only with papal guidance.20 At the time, Innocent may have had the Venetians rather than the Greeks in mind, especially as he had already rejected Alexius Angelus’s attempt to win papal approval for his restoration. The crusaders at Zara could not be so detached or theoretical. Legal and moral niceties could cost lives and decide the fate of the crusade, in the winter of 1202–3 far from simply academic considerations. However, moral posturing was not the preserve of only one side of the argument. Despite the outrage expressed against it, crusader attacks on Christians had not been seen as too shocking in the past – except by the victims. Towns on the Danube – Balkan road east had been attacked or threatened on each of the first three major expeditions. The cities of Thrace and Cyprus, and Messina in Sicily, had all fallen to the soldiers of the Third Crusade. As even the pope admitted, there were circumstances where such fratricidal violence by
In early December, Boniface of Montferrat finally reached Zara, followed, by the end of the month, by a delegation from Philip of Swabia and his brother-in-law Alexius Angelus. In return for placing Alexius on the Byzantine throne, they offered the crusaders union of the Greek Orthodox church with Rome; a gift of 200,000 silver marks; provisions for every man in the army; 10,000 Greeks to accompany the crusaders to Egypt; and the promise of a permanent Byzantine garrison of 500 knights in Outremer.21 The timing and content were well judged to appeal to their audience, suggesting at the least careful preparation if not active collusion with elements of the crusade leadership, especially Boniface of Montferrat. What was being offered amounted to the realization of western expectations regarding Byzantium and the crusade and a revolution in relations between the Greek church and Rome. The well-informed Venetians probably recognized the inflated implausibility of some of the details, while acknowledging the potential benefits of changing the Greek regime, not least to their commercial position. The convenience of the plan’s presentation just as the crusaders were contemplating the next season’s campaign was hardly fortuitous. But the prospect on offer was little short of momentous.
BYZANTIUM AND THE CRUSADE
No such thing as a ‘western attitude’ to Byzantium existed in the twelfth and early thirteenth century. It remains a myth of crusading historiography. Instead, a variety of responses was determined by region, status, the nature of the contact or its timing. On the levels of silks, saints, soldiers, trade and icons, exchange between western Europeans and the Greeks was habitual, customary and usually mutually beneficial. While differences in religious observance increasingly grated on a western ecclesiastical establishment eager to impose discipline and achieve uniformity, there were few awkward diplomatic or political absolutes, except, perhaps, for Byzantine foreign policy’s single-minded Palmerstonian pursuit of material interests rather than set alliances or ideological posturing, a stance that so irritated successive popes and crusade leaders. Over the politics of Italy, the Danube basin, the Balkans, the eastern Mediterranean, the Black Sea, Outremer and the Near East, western European powers and Byzantium competed, cooperated and coexisted. Whatever else, the scheme put to the crusader army at Zara spoke of contact, not alienation. It also recognized the implosion of Byzantine power since the death of Manuel I in 1180.22
Byzantium under Manuel I presented an image of universal power and a reality only little short of it. Although under Manuel’s predecessors Alexius I and John II the recovery from the defeats of the eleventh century – in Italy, Asia Minor, Syria and the Balkans – was territorially modest, by reasserting control over the ports of western Asia Minor and restoring the integrity of the Danube frontier, internal stability and the conditions for economic prosperity were secured. By 1180, the Byzantine empire included the Balkans south of the Danube, the islands of the Ionian and Aegean seas, Crete, Cyprus, western Asia Minor, Cilicia and the coastal ports of the southern Black Sea. A gold currency underpinned a comprehensive tax system and a centralized bureaucracy almost unknown further west. Diplomatically, the Greek emperor retained interests and correspondence from the Atlantic to the Persian Gulf, the Baltic to the Sahara Desert. Byzantine fleets operated from the Black Sea and the Adriatic to the Nile Delta. Satellite states sporadically festooned the frontiers, including Frankish Antioch and Seljuk Konya. Constantinople remained easily the grandest, largest and richest Christian city in the world, its population still about 375,000– 400,000, six or seven times the size of Paris, despite its slums, inequalities of income, public affluence and private squalor, a magnet for trading communities from all over the Mediterranean and beyond. The imperial guard recruited from as far as Scandinavia and the British Isles; visitors came from Nubia. The quarters occupied by the commerical representatives of Venice, Pisa and Genoa were matched by a large Jewish settlement and a Muslim presence recognized by a number of mosques in the city.
The serenity of Manuel’s empire masked certain underlying problems. The Comnenan rulers since 1081 relied more than previous emperors on their own family rather than on state officials, on the army rather than the civilians. Power became increasingly focused on the person and immediate entourage of the emperor rather than the civil servants and system of government over which he presided. Public centralization was eroded by a sort of privatized centralization, a deliberate policy of subcontracting military, commerical and fiscal functions of the state to foreign mercenaries – Turks, Franks, Armenians, Slavs – Italian traders, provincial landlords and defence contractors. The enormous consumption of Constantinople unbalanced the economy as well as politics. Academic uncertainty remains about the extent of economic growth in some provinces, but many parts of the empire clearly seemed highly attractive to acquisitive outsiders. The empire faced active or potential threats from the kings of Sicily; German emperors; Slavs beyond the Danube; Bulgarian and Serb freedom fighters in the Balkans; Armenians in Cilicia; and Turks in Asia Minor and Syria. As with many later cosmopolitan and imperial capitals, xenophobia stalked sections of the Greek population of Constantinople, inducing paranoia that spilled over into violent anti- western riots in 1171 and 1182. This undertow of Greek nationalism, evident in the strand of self-conscious Hellenism in the culture of twelfth-century Byzantium, counterbalanced Manuel’s eclectic pro-western policies, which included holding Frankish-style tournaments and taking a German and then an Antiochene Frankish wife.
Two central weaknesses persisted despite the political success of the Comnenans; the vulnerability of the
