His conciliatory approach may simply have been a thin diplomatic veneer designed to mask his true intentions, because he was simultaneously probing the possibility of an anti-Greek alliance with other Latin princes. He tried to establish a line of communication with Godfrey of Bouillon, already camped outside Constantinople, proposing that they join forces and attack Alexius, but his envoys seem to have been intercepted. Intrigue was certainly in the air, because Godfrey was warned by his advisers to be wary of assassination attempts, even by such exotic methods as poisoned cloaks. With his schemes frustrated, Bohemond left the bulk of the army in the care of Tancred to pass Easter near Roussa and rode on to Constantinople to open negotiations with the emperor.40
The Graeco-Latin detente survived the piecemeal approach of the princes' armies towards the Byzantine capital, but an underlying current of mutual suspicion and ingrained antipathy was running dangerously close to the surface throughout the first half of 1097.
THE GREAT CITY OF CONSTANTINOPLE
The arduous journey from western Europe brought each contingent of the crusading host to the gates of Constantinople. There was no greater Christian city on earth. Its staggering size, exotic opulence and cosmopolitan populace astounded the Franks. One wrote:
Oh what a noble and beautiful city is Constantinople! How many monasteries and palaces it contains, constructed with wonderful skill! It would take too long to describe all the wealth that is there of every kind, of gold, of silver, all types of clothes, holy relics ... There are, I think, around twenty thousand eunuchs living there always.41
Poised as it was on an isthmus jutting out into the Bosphorus Strait - the thin body of water that connects the Mediterranean with the Black Sea and separates the European and Asian continents - the city was perfectly placed to exploit the pulsing trade route to the Orient. Known in antiquity as Byzantion (from which the word Byzantium is derived), it was renamed in honour of Constantine the Great when he chose it as the site of his new capital of the Roman Empire in 324 CE. The city was shaped into a rough triangle, two sides of which abutted the sea, and was enclosed within massive twin walls - to the landward side these presented an awesome, impenetrable barrier, seven kilometres long, up to five metres thick and twenty metres high. The huge size of this metropolis dwarfed the largest city in Latin Europe ten-fold; its teeming populace, perhaps 500,000 strong, could have inhabited an entire realm back in the West.
Alexius Comnenus was determined to protect this great city at all costs. So even though the crusaders had come to Byzantium as allies, the emperor forced them to camp outside Constantinople s walls. One Latin eyewitness recalled that we did not try to enter the city because it was not agreeable to [Alexius] for he feared that possibly we would plot some harm to him... [We could only] enter the city at the rate of five or six each hour. Thus while we were leaving, others were entering to pray in the churches.42 Those who were lucky enough to get in were greeted by sights of unparalleled grandeur. The colossal wealth of the Greeks was legendary, and the magnificence of their capital spoke of an empire possessed of immeasurable fortune and an ancient heritage.
The first stop of any crusader would have been the Basilica of St Sophia, the largest, most spectacular Christian church in the world. Built in the sixth century, its vast interior glistened, its walls, vaulted corridors and domes being covered with dramatic frescoes and mosaics whose craftsmanship far outstripped anything the Latins would have seen in western Europe. This giant structure was topped by an enormous dome more than fifty metres high and thirty metres wide. The basilica, like the city as a whole, was renowned for its collection of sacred relics. A visitor to Constantinople might see Christ's crown of thorns and pieces of the cross upon which he was crucified; the Virgin Mary's robe and locks of her hair; at least two heads of John the Baptist; and the bones of virtually all the apostles.
Elsewhere in the city, the Franks could marvel at countless wonders: the Forum of Constantine, dominated by a fifty-metre-high column, upon the summit of which stood a gigantic statue of the city's founder modelled as Apollo; the Hippodrome - an ancient stadium famed for its brutal chariot races, capable of seating a crowd of 100,000; and the Equestrian Statue of Justinian - a monumental marble column topped by a bronze of the emperor astride his horse, rendered three times life-size, holding his hand out to the east as a symbolic warning to the Persians.
The most esteemed visitors might gain access to the imperial residence itself, the Palace of the Blachernae, situated atop a hill in the north-west corner of Constantinople, overlooking the city and its surroundings. A crusader who saw it in the twelfth century wrote:
On its three sides the Palace offers to its inhabitants the triple pleasure of gazing alternately on the sea, the countryside, and the town. The exterior of the palace is of almost incomparable loveliness and its interior surpasses anything that I can say about it. It is decorated throughout with gold and various colours and the floor is paved with cleverly arranged marble.43
Confronted by this array of magnificence, most First Crusaders were utterly overawed. They had been born in the Latin West, where the distant echo of ancient Rome reverberated in the collective memory, the touchstone of a golden age in human history. Now, as they walked the streets of Constantinople, the glory and power of that empire seemed reborn, incarnate in living colour before their eyes. Few could have doubted that they had reached the mighty beating heart of western civilisation.
The oaths to Alexius
The Emperor Alexius looked to capitalise upon the splendour of his city. Having herded the crusade's second wave through the western reaches of the empire with some skill, he now had to deal with the Franks at the core of Byzantium. With the various contingents of the expedition projected to congregate at Constantinople, Alexius had an ideal opportunity to assert imperial authority over the venture, capitalising upon the imposing grandeur of the Byzantine court to dazzle the Latin princes into submissive accord. But the prospect of a potentially unruly Frankish horde gathering outside his walls filled the emperor with concern. He knew that, left to their own devices, the massed ranks of crusaders would become increasingly difficult to supply and their acquisitive eyes might even turn upon Constantinople itself. Indeed, soon after the first of the main armies under Godfrey of Bouillon had established camp on the outskirts of the city, tensions flared and there was open skirmishing between Baldwin of Boulogne and Byzantine troops.44
Alexius wisely chose to exploit the fragmented nature of the crusader host, dealing with each prince individually as he arrived at Constantinople and then avoiding a build-up of discontented Latins by shipping them across the Bosphorus as rapidly as possible. Once in Asia Minor they could be allowed to assemble without posing any direct threat to the Greeks. Anna Comnena recalled that the emperor 'used every means, physical and psychological, to hurry [the Franks] into crossing the straits', a clear instance of his prioritising Byzantine interests, because this policy exposed the second wave of crusaders to the same destructive fate suffered by the first.45
Before moving them on, however, Alexius was determined to establish a degree of control over the princes, harnessing the raw power of their armies to fulfil the needs of the empire and looking to capitalise upon any success they might enjoy.
Contrary perhaps to the crusaders' expectations, he had no plans personally to lead their expedition on to Jerusalem. The emperor's mind was instead focused upon two absolute and unwavering priorities: protecting the position of his fledgling Comneni dynasty and preserving the delicate balance of Byzantine security. Alexius was happy to assist the First Crusade, even keen for it to succeed, but he was never going to jeopardise Greek interests to further the Latin cause, and conducting a protracted campaign in the distant Holy Land would have exposed his rule to overthrow and the empire to invasion.
In lieu of direct participation, Alexius sought to bind the leading crusaders to him through bonds of service. Every Frankish prince or noble passing by Constantinople was called into the
magnificent city for an audience with the emperor and required to offer him an oath of allegiance. After prolonged and fractious negotiation, Godfrey of Bouillon led the cream of Lotharingian aristocracy into the imperial palace around 20 January 1097 to find Alexius 'seated, as was his custom, looking powerful on the throne of his sovereignty, not getting up to offer kisses [of greeting] to the duke nor to anyone'. Maintaining this air of regal majesty, the emperor received their submission, thus apparently creating 'an unbreakable chain of complete trust and friendship' between them.46
The Latins' pledges had two components. The first was a solemn promise that whatever cities, countries or forts he might in future subdue, which had in the first place belonged to the Roman Empire, he would hand over to the officer appointed by the emperor'. This meant that any territory captured in Asia Minor and even beyond would have to be handed over to the Byzantines. The second part of the accord is much more difficult to pin down. It seems to have involved an oath of vassalage to Alexius, partly modelled on western forms of lordship, the precise details of which are impossible to recover. A bond of peace and mutual friendship was certainly implied; Alexius, as the senior partner, could direct the princes to do his bidding; they agreed not to harm the empire, but in return might expect imperial aid and counsel. It is extremely unlikely that, in connection with this last clause, Alexius ever formally affirmed his intention to join the crusaders on their march to Jerusalem. He was too agile a diplomat to commit himself in advance to such a risky venture. But the reciprocal obligations inherent in vassalic relations left the Franks expecting that he would reinforce their expedition at some point.47
Once Godfrey established the precedent of making this submission, most crusader princes followed suit without protest. With his thoughts of challenging the Greeks sidelined, Bohemond, for example, now sought to ingratiate himself with his former enemy. Arriving at Constantinople around 10 April, he was summoned to an audience and readily acquiesced to the oath. In return, he tried to convince Alexius to make him the de facto military commander of the crusade, but the emperor tactfully prevaricated 48 Some, however, resisted Alexius' demands. As Raymond of Toulouse arrived in the city around 21 April, news reached him that the southern French forces trailing some days' journey behind had fallen prey to repeated attack. Suspecting foul play, he stoutly refused to proffer the same oath given by all the other princes, despite Alexius' best efforts to pressure him into submission. In the end, he agreed to a modified pact, vowing not to threaten the emperor's power or possessions. Modern historians' have persistently maintained that Raymond's proud stance earned him Alexius' respect and friendship, uniting the two in an alliance that would endure through the course of the crusade. This is primarily based on the testimony of Anna Comnena, who, with the benefit of hindsight, wrote of Raymond in glowing terms, revealing nothing of the wrangling at Constantinople. In reality, there is nothing in Raymond's conduct to suggest that he and the emperor enjoyed an especially cordial relationship in 1097. Indeed, according to a member of Raymond's own army, he was actually plotting to attack the Greeks at this point. A number of lesser princes, including Tancred of Hauteville and Baldwin of Boulogne, are known to have initially avoided taking any oath, evading the emperor's net by immediately crossing the Bosphorus.49
Alexius had, nonetheless, asserted his dominance over the crusading elite and looked set to manipulate and exploit the expedition. With typical Byzantine largesse, he sweetened the act of capitulation by showering the Latin princes with lavish gifts. Godfrey acquired a mound of gold and silver from the imperial treasury, along with precious purple silks and valuable horses. He also received a hefty weekly stipend with which to purchase supplies for his army at local markets, although all of this soon poured back into Greek coffers. Bohemond was reportedly amazed and overjoyed when, after making his pledge, he was shown a room so packed with diverse riches 'that it was impossible for anyone to walk in it' and was told that the entire contents were his. Raymond of Toulouse alone gained little in the way of treasure because of his intransigence.50
The emperor also offered the Franks priceless intelligence about the challenges that lay ahead in Asia Minor. Bohemond is known to have consulted him about how to supply the Latin host during the initial penetration of this territory, and Alexius provided the princes with a clear explanation and analysis of the Muslim foe now confronting the First Crusade. Anna Comnena noted that the emperor 'warned [them] about the things likely to happen on their journey [and] gave them profitable advice. They were instructed in the methods normally used by the Turks in battle; told how they should draw up a battle-line, how to lay ambushes; advised not to pursue far when the enemy ran away in flight. Later Alexius supplemented this tactical advice with an insight into his own pragmatic brand of politics, counselling the Franks to exploit the political and religious divisions that afflicted Islam.51
The world of Islam
The Muslim world with which Alexius sought to acquaint the crusaders had undergone a dramatic transformation in the four and a half centuries since Muhammad first proclaimed the faith in a distant corner of the Arabian peninsula. After the prophet's death in 632 CE, his successors prosecuted a series of wildly energetic military campaigns that saw the Islamic state sweep across the eastern Mediterranean, north Africa and Persia. The great cities of the East -Damascus, Baghdad and Cairo - all fell within a decade; Jerusalem, a city deeply revered as the site of Muhammad's ascent to heaven, was conquered in 638. By the start of the eighth century Islam had engulfed the Mediterranean world, to the east threatening Constantinople, in the west menacing southern France.
In spite of this extraordinary expansion, the Islamic state was, from early in its history, fundamentally and bitterly divided. Two sects claimed descent from Muhammad: to the north Sunni Islam was based at the Persian city of Baghdad, capital of what was known as the Abbasid caliphate; meanwhile, the southern Fatimid caliphate, centred on Cairo, adhered to the Shi'a form of Islam. By the start of the eleventh century, this grave breach had crippled the Muslim world, as the struggle between Sunnites and Shi'ites took precedence above all other affairs and the power of both Baghdad and Cairo stagnated.52 In ethnic terms, Middle Eastern Islam had, up to this point, been dominated by Arabs and Persians, but from 1055 onwards an injection of new blood reinvigorated the Abbasid caliphate. Wild nomadic Turcoman tribesmen from the steppe-lands of Russia converted to Sunni Islam and overran Mesopotamia. When these Turks conquered Baghdad, their leader, an ambitious warlord named
Tughrul Beg, was proclaimed sultan (literally power') and his family, the Seljuqs, became the ruling dynasty of the Sunni north.
By the end of the eleventh century these Seljuq Turks held sway over Iran, Iraq, Syria and Palestine. The Egyptian Fatimids of Cairo had, for some years, been retreating in the face of this Seljuq aggression, and Alexius actually advised the crusaders to negotiate an anti-Turkish pact with them. A branch of the Seljuq family also seized control of much of Asia Minor after the Byzantines were crushed at Manzikert in 1071, and began styling themselves as the sultans of Rum (the eastern Roman Empire).
It was these Seljuqs who would confront the First Crusade once it breached the frontier with Islam in 1097, and Alexius Comnenus did his best to prepare the Franks for their distinct brand of warfare. The traditional mainstay of their armies was the lightly armoured mounted warrior, astride a fleet-footed, agile pony, armed with a powerful composite bow that enabled him to loose streams of arrows from horseback. He might also be armed with a light lance, single-edged sword, axe or dagger. These troops relied upon speed of movement and rapid manoeuvrability to overcome their opponents. They classically employed two main tactics: encirclement, in which they would seek to surround an enemy on all sides in a fast-moving, swirling mass, while unleashing unending volleys of arrows; and feigned retreat, the technique of turning tail in battle in the hope of prompting your opponent to give chase, the indiscipline of which would break their formation and leave them vulnerable to sudden c
ounterattack. This style of combat was still favoured by the Seljuqs of Asia Minor, but the Turks of Syria and Palestine had begun to adopt a wider array of Persian and Arab military practices, adjusting to the use of larger infantry forces and to the needs of siege warfare.55
The Muslims who met the crusaders in battle were skilled and ferocious warriors. They did not, however, see themselves as being engaged in a grand religious struggle with Christianity. The Muslim religion had, from its earliest days, embraced warfare^ Muhammad himself prosecuted a series of brutal campaigns while subjugating
Mecca, and the exponential expansion of Islam was fuelled by raw Arab bellicosity and impassioned religious devotion. Islamic doctrine achieved a far more rapid and natural union of faith and violence than that concocted in the Latin West. By the late eighth century, Muslim jurists had enshrined these ideals in a formal theory of holy war. The obligation to prosecute jihad, the military struggle against the infidel, was incumbent upon all able-bodied Muslims, and would, it was believed, pave the way to paradise. But as decades and then centuries passsed, and the Islamic state began to focus upon peaceful settlement rather than conquest, the ideal of expansionist jihad gradually fell into abeyance.
