The Crusades, as they were historically developed, are mixed up with the religious ideas of the Middle Ages, with the domination of popes, with the feudal system, with chivalry, with monastic life, with the central power of kings, with the birth of mercantile States, with the fears and interests of England, France, Germany, and Italy, for two hundred years,—yea, with the architecture, commerce, geographical science, and all the arts then known. All these principalities and powers and institutions and enterprises were affected by them, so that at their termination a new era in civilization began. Grasp the Crusades, and you comprehend one of the forces which undermined the institutions of the Middle Ages.
It is not a little remarkable that the earliest cause of the Crusades, so far as I am able to trace, was the adoption by the European nations of some of the principles of Eastern theogonies which pertained to self-expiation. An Asiatic theological idea prepared the way for the war between Europe and Asia. The European pietist embraced the religious tenets of the Asiatic monk, which centred in the propitiation of the Deity by works of penance. One of the approved and popular forms of penance was a pilgrimage to sacred places,—seen equally among degenerate Christian sects in Asia Minor, and among the Mohammedans of Arabia. What place so sacred as Jerusalem, the scene of the passion and resurrection of our Lord? Ever since the Empress Helena had built a church at Jerusalem, it had been thronged with pious pilgrims. A pilgrimage to old Jerusalem would open the doors of the New Jerusalem, whose streets were of gold, and whose palaces were of pearls.
At the close of the tenth century there was great suffering in Europe, bordering on despair. The calamities of ordinary life were so great that the end of the world seemed to be at hand. Universal fear of impending divine wrath seized the minds of men. A great religious awakening took place, especially in England, France, and Germany. In accordance with the sentiments of the age, there was every form of penance to avert the anger of God and escape the flames of hell. The most popular form of penance was the pilgrimage to Jerusalem, long and painful as it was. Could the pilgrim but reach that consecrated spot, he was willing to die. The village pastor delivered the staff into his hands, girded him with a scarf, and attached to it a leathern scrip. Friends and neighbors accompanied him a little way on his toilsome journey, which lay across the Alps, through the plains of Lombardy, over Illyria and Pannonia, along the banks of the Danube, by Moesia and Dacia, to Belgrade and Constantinople, and then across the Bosphorus, through Bithynia, Cilicia, and Syria, until the towers and walls of Tyre, Ptolemais, and Caesarea proclaimed that he was at length in the Holy Land. Barons and common people swell the number of these pilgrims. The haughty knight, who has committed unpunished murders, and the pensive saint, wrapt in religious ecstasies, rival each other in humility and zeal. Those who have no money sell their lands. Those who have no lands to sell throw themselves on Providence, and beg their way for fifteen hundred miles among strangers. The roads are filled with these travellers,—on foot, in rags, fainting from hunger and fatigue. What sufferings, to purchase the favor of God, or to realize the attainment of pious curiosity! The heart almost bleeds to think that our ancestors could ever have been so visionary and misguided; that such a gloomy view of divine forgiveness should have permeated the Middle Ages.
But the sorrows of the pious pilgrims did not end when they reached the Holy Land. Jerusalem was then in the hands of the Turks and Saracens (or Orientals, a general name given to the Arabian Mohammedans), who exacted two pieces of gold from every pilgrim as the price of entering Jerusalem, and moreover reviled and maltreated him. The Holy Sepulchre could be approached only on the condition of defiling it.
The reports of these atrocities and cruelties at last reached the Europeans, filling them with sympathy for the sufferers and indignation for the persecutors. An intense hatred of Mohammedans was generated and became universal,—a desire for vengeance, unparalleled in history. Popes and bishops weep; barons and princes swear. Every convent and every castle in Europe is animated with deadly resentment. Rage, indignation, and vengeance are the passions of the hour,—all concentrated on "the infidels," which term was the bitterest reproach that each party could inflict on the other. An infidel was accursed of God, and was consigned to human wrath. And the Mohammedans had the same hatred of Christians that Christians had of Mohammedans. In the eyes of each their enemies were infidels; and they were enemies because they were regarded as infidels.
Such a state of feeling in both Europe and Asia could not but produce an outbreak,—a spark only was needed to kindle a conflagration. That spark was kindled when Peter of Amiens, a returned hermit, aroused the martial nations to a bloody war on these enemies of God and man. He was a mean-looking man, with neglected beard and disordered dress. He had no genius, nor learning, nor political position. He was a mere fanatic, fierce, furious with ungovernable rage. But he impersonated the leading idea of the age,—hatred of "the infidels," as the Mohammedans were called. And therefore his voice was heard. The Pope used his influence. Two centuries later he could not have made himself a passing wonder. But he is the means of stirring up the indignation of Europe into a blazing flame. He itinerates France and Italy, exposing the wrongs of the Christians and the cruelties of the Saracens,—the obstruction placed in the way of salvation. At length a council is assembled at Clermont, and the Pope—Urban II.— presides, and urges on the sacred war. In the year 1095 the Pope, in his sacred robes, and in the presence of four hundred bishops and abbots, ascends the pulpit erected in the market-place, and tells the immense multitude how their faith is trodden in the dust; how the sacred relics are desecrated; and appeals alike to chivalry and religion. More than this, he does just what Mohammed did when he urged his followers to take the sword: he announces, in fiery language, the fullest indulgence to all who take part in the expedition,—that all their sins shall be forgiven, and that heaven shall be opened to them. "It is the voice of God," they cry; "we will hasten to the deliverance of the sacred city!" Every man stimulates the passions of his neighbor. All vie in their contributions. The knights especially are enthusiastic, for they can continue their accustomed life without penance, and yet obtain the forgiveness of their sins. Religious fears are turned at first into the channel of penance; and penance is made easy by the indulgence of the martial passions. Every recruit wore a red cross, and was called croise—cross-bearer; whence the name of the holy war.
Thus the Crusades began, at the close of the eleventh century, when William Rufus was King of England, when Henry IV. was still Emperor of Germany, when Anselm was reigning at Canterbury as spiritual head of the English Church, ten years after the great Hildebrand had closed his turbulent pontificate.
I need not detail the history of this first Crusade. Of the two hundred thousand who set out with Peter the Hermit,—this fiery fanatic, with no practical abilities,—only twenty thousand succeeded in reaching even Constantinople. The rest miserably perished by the way,—a most disorderly rabble. And nothing illustrates the darkness of the age more impressively than that a mere monk should have been allowed to lead two hundred thousand armed men on an enterprise of such difficulty. How little the science of war was comprehended! And even of the five hundred thousand men under Godfrey, Tancred, Bohemond, and other great feudal princes,—men of rare personal valor and courage; men who led the flower of the European chivalry,—only twenty-five thousand remained after the conquest of Jerusalem. The glorious array of a hundred and fifty thousand horsemen, in full armor, was a miserable failure. The lauded warriors of feudal Europe effected almost nothing. Tasso attempted to immortalize their deeds; but how insignificant they were, compared with even Homer's heroes! A modern army of twenty-five thousand men could not only have put the whole five hundred thousand to rout in an hour, but could have delivered Palestine in a few mouths. Even one of the standing armies of the sixteenth century, under such a general as Henry IV. or the Duke of Guise, could have effected more than all the crusaders of two hundred years. The crusaders numbered many heroes, but scarcely a single general. There was no military discipline among them: they knew nothing of tactics or strategy; they fought pell-mell in groups, as in the contests of barons among themselves. Individually they were gallant and brave, and performed prodigies of valor with their swords and battle-axes; but there was no direction given to their strength by leaders.
The Second Crusade, preached half a century afterwards by Saint Bernard, and commanded by an Emperor of Germany and a King of France, proved equally unfortunate. Not a single trophy consoled Europe for the additional loss of two hundred thousand men. The army melted away in foolish sieges, for which the crusaders had no genius or proper means.
The Third Crusade, and the most famous, which began in the year 1189, of which Philip Augustus of France, Richard Coeur de Lion of England, and Frederic Barbarossa of Germany were the leaders,—the three greatest monarchs of their age,—was also signally unsuccessful. Feudal armies seem to have learned nothing in one hundred years of foreign warfare; or else they had greater difficulties to contend with, abler generals to meet, than they dreamed of, who reaped the real advantages,—like Saladin. Sir Walter Scott, in his "Ivanhoe," has not probably exaggerated the military prowess of the heroes of this war, or the valor of Templars and Hospitallers; yet the finest array of feudal forces in the Middle Ages, from which so much was expected, wasted its strength and committed innumerable mistakes. It proved how useless was a feudal army for a distant and foreign war. Philip may have been wily, and Richard lion-hearted, but neither had the generalship of Saladin. Though they triumphed at Tiberias, at Jaffa, at Caesarea; though prodigies of valor were performed; though Ptolemais (or Acre), the strongest city of the East, was taken,—yet no great military results followed. More blood was shed at this famous siege, which lasted three years, than ought to have sufficed for the subjugation of Asia. There were no decisive battles, and yet one hundred battles took place under its walls. Slaughter effected nothing. Jerusalem, which had been retaken by the Saracens, still remained in their hands, and never afterwards was conquered by the Europeans. The leaders returned dejected to their kingdoms, and the bones of their followers whitened the soil of Palestine.
