Urban told them that under their general Jesus Christ they, the Christian, the invincible army, would march to certain victory. In the eleventh century this language was no metaphor, for the Cluniac monk spoke as the mouthpiece of a god who was there actually among them, offering the cross he brought from the grave, and promising them triumphs: not the common triumphs which may be won by mans unaided strength, but the transcendent glory which belongs to beings of another world.
So the crusaders rode out to fight, the originals of the fairy knights, clad in impenetrable armour, mounted on miraculous horses, armed with resistless swords, and bearing charmed lives.
Whole villages, even whole districts, were left deserted; land lost its value; what could not be sold was abandoned; and the peasant, loaded with his poor possessions, started on foot with his wife and children in quest of the Sepulchre, so ignorant of the way that he mistook each town upon the road for Zion. Whether he would or no, the noble had to lead his vassals or be forsaken, and riding at their head with his hawks and hounds, he journeyed towards that marvellous land of wealth and splendour, where kingdoms waited the coming of the devoted knight of God. Thus men, women, and children, princes and serfs, priests and laymen, in a countless, motley throng, surged toward that mighty cross and tomb whose possessor was raised above the limitations of the flesh.
The crusaders had no commissariat and no supply train, no engines of attack, or other weapons than those in their hands, and the holy relics they bore with them. There was no general, no common language, no organization; and so over unknown roads, and through hostile peoples, they wandered from the Rhine to the Bosphorus, and from the Bosphorus to Syria.
These earlier crusades were armed migrations, not military invasions, and had they met with a determined enemy, they must have been annihilated; but it chanced that the Syrians and Egyptians were at war, and the quarrel was so bitter that the caliph actually sought the Christian alliance. Even under such circumstances the waste of life was fabulous, and, had not Antioch been betrayed, the starving rabble must have perished under its walls. At Jerusalem, also, the Franks were reduced to the last extremity before they carried the town; and had it not been for the arrival of a corps of Genoese engineers, who built movable towers, they would have died miserably of hunger and thirst. Nor was the coming of this reinforcement preconcerted. On the contrary, the Italians accidentally lost their ships at Joppa, and, being left without shelter, sought protection in the camp of the besiegers just in time.
So incapable were the crusaders of regular operations, that even when the towers were finished and armed, the leaders did not know how to fill the moat, and Raymond of Saint Gilles had nothing better to propose than to offer a penny for every three stones thrown into the ditch.
On July 15, 1099, Jerusalem was stormed; almost exactly three years after the march began. Eight days later Godfrey de Bouillon was elected king, and then the invaders spread out over the strip of mountainous country which borders the coast of Palestine and Syria, and the chiefs built castles in the defiles of the hills, and bound themselves together by a loose alliance against the common enemy.
The decentralization of the colony was almost incredible. The core of the kingdom was the barony of Jerusalem, which extended only from the Egyptian desert to a stream just north of Beyrout, and inland to the Jordan and the spurs of the hills beyond the Dead Sea, and yet it was divided into more than eighteen independent fiefs, whose lords had all the rights of sovereignty, made war, administered justice, and coined money.102
Beside these petty states, the ports were ceded to the Italian cities whose fleets helped in the conquest. Venice, Genoa, and Pisa held quarters in Ascalon, Joppa, Tyre, Acre, and Beyrout, which were governed by consuls or viscounts, who wrangled with each other and with the central government.
Such was the kingdom over which Godfrey reigned, but there were three others like it which together made up the Frankish monarchy. To the north of the barony of Jerusalem lay the county of Tripoli, and beyond Tripoli, extending to Armenia, the principality of Antioch. To the east of Antioch the county of Edessa stretched along the base of the Taurus Mountains and spread out somewhat indefinitely beyond the Euphrates.
Thus on the north Edessa was the outwork of Christendom, while to the south the castle of Karak, which commanded the caravan road between Suez and Damascus, held a corresponding position among the hills to the east of the Dead Sea.
Beyond the mountains the great plain sweeps away into Central Asia, and in this plain the Franks never could maintain their footing. Their failure to do so proved their ruin, for their position lay exposed to attack from Damascus; and it was by operating from Damascus as a base that Saladin succeeded in forcing the pass of Banias, and in cutting the Latin possessions in two at the battle of Tiberias.
A considerable body of Europeans were thus driven in like a wedge between Egypt and the Greek Empire, the two highest civilizations of the Middle Ages, while in front lay the Syrian cities of the plain, with whom the Christians were at permanent war. The contact was the closest, the struggle for existence the sharpest, and the barbaric mind received a stimulus not unlike the impulse Gaul received from Rome; for the interval which separated the East from the West, at the beginning of the twelfth century, was probably not less than that which divided Italy from Gaul at the time of Cæsar.
When Godfrey de Bouillon took the cross, the Byzantine Empire was already sinking. The Eastern trade which, for so many centuries, had nourished its population, was beginning to flow directly from Asia into Italy, and, as the economic aristocracy of the capital lost its nutriment, it lost its energy. Apparently it fell in 1081, in the revolution which raised Alexius Comuenus to the throne. Because Alexius sacked Constantinople with a following of mongrel Greeks, Slavs, and Bulgarians, he has been called the first Greek emperor, but in reality the pure Greek blood had long since perished. The Byzantine population at the end of the eleventh century was the lees of a multitude of races, a mixture of Slavs, Armenians, Jews, Thracians, and Greeks; a residuum of the most tenacious organisms, after all that was higher had disappeared. The army was a mixed horde of Huns, Arabs, Italians, Britons, Franks; of all in short who could fight and were for sale, while the Church was servile, the fancy dead, and art and literature were redolent of decaying wealth.
Nevertheless, ever since the fall of Rome, Constantinople had been the reservoir whence the West had drawn all its materialistic knowledge, and therefore, it was during the centuries when the valley of the Danube was closed, that the arts fell to their lowest ebb beyond the Alps and Rhine. After pilgrimages began again in the reign of Stephen, the Bosphorus lay once more in the path of travel, and as the returning palmers spread over the West, a revival followed in their track; a revival in which the spirit of Byzantium may yet be clearly read in the architecture of Italy and France. Saint Mark is a feeble imitation of Saint Sophia, while Viollet-le-Duc has described how long he hesitated before he could decide whether the carving of Vézelay, Autun, and Moissac was Greek or French; and has dwelt upon the laborious care with which he pored over all the material, before he became convinced that the stones were cut by artists trained at Cluny, who copied Byzantine models.103
