THE CONQUEST OF NORTHERN AFRICA (643-689).—The lieutenants of the Caliphs were obliged to do much and fierce fighting before they obtained possession of the oft-disputed shores of North Africa. They had to contend not only with the Græco-Roman Christians of the coast, but to battle also with the idolatrous Moors of the interior. Furthermore, all Europe had begun to feel alarm at the threatening advance of the Saracens; so now Roman soldiers from Constantinople, and Gothic warriors from Italy and Spain hastened across the Mediterranean to aid in the protection of Carthage, and to help arrest the alarming progress of these wild fanatics of the desert.
But all was of no avail. Destiny had allotted to the followers of the Apostle the land of Hannibal and Augustine. Carthage was taken and razed to the ground, and the entire coast from the Nile to the Atlantic, was forced to acknowledge the authority of the Caliphs. By this conquest all the countries of Northern Africa, whose history for a thousand years had been intertwined with that of the opposite shores of Europe, and which at one time seemed destined to share in the career of freedom and progress opening to the peoples of that continent, were drawn back into the fatalism, the despotism, and the stagnation of the East. From being an extension of Europe, they became once more an extension of Asia.
ATTACKS UPON CONSTANTINOPLE.—Only fifty years had now passed since the death of Mohammed, but during this short time his standard had been carried by the lieutenants of his successors through Asia to the Hellespont on the one side, and across Africa to the Straits of Gibraltar on the other. From each of these two points, so remote from each other, the fanatic warriors of the desert were casting longing glances across those narrow passages of water which alone separated them from the single continent that their swift coursers had not yet traversed, or whence the spoil of the unbelievers had not yet been borne to the feet of the Vicar of the Prophet of God. We may expect to see the Saracens at one or both of these points attempt the invasion of Europe.
The first attempt was made in the East (in 668), where the Arabs endeavored to gain control of the Bosporus, by wresting Constantinople from the hands of the Eastern emperors. But the capital was saved through the use, by the besieged, of a certain bituminous compound, called Greek Fire. In 716, the city was again besieged by a powerful Moslem army; but its heroic defence by the Emperor Leo III. saved the capital for several centuries longer to the Christian world.
THE CONQUEST OF SPAIN (711).—While the Moslems were thus being repulsed from Europe at its eastern extremity, the gates of the continent were opened to them by treachery at the western, and they gained a foothold in Spain. At the great battle of Xeres (711), Roderic, the last of the Visigothic kings, was hopelessly defeated, and all the peninsula, save some mountainous regions in the northwest, quickly submitted to the invaders. Thus some of the fairest provinces of Europe were lost to Christendom for a period of nearly eight hundred years.
No sooner had the subjugation of the country been effected than multitudes of colonists from Arabia, Syria, and North Africa crowded into the peninsula, until in a short time the provinces of Seville, Cordova, Toledo, and Granada became Arabic in dress, manners, language, and religion.
INVASION OF FRANCE: BATTLE OF TOURS (732).—Four or five years after the conquest of Spain, the Saracens crossed the Pyrenees, and established themselves upon the plains of Gaul. This advance of the Moslem hosts beyond the northern wall of Spain was viewed with the greatest alarm by all Christendom. It looked as though the followers of Mohammed would soon possess all the continent. As Draper pictures it, the Crescent, lying in a vast semi-circle upon the northern shore of Africa and the curving coast of Asia, with one horn touching the Bosporus and the other the Straits of Gibraltar, seemed about to round to the full and overspread all Europe.
In the year 732, exactly one hundred years after the death of the great Prophet, the Franks, under their renowned chieftain, Charles, and their allies met the Moslems upon the plains of Tours in the centre of Gaul, and committed to the issue of a single battle the fate of Christendom and the future course of history. The desperate valor displayed by the warriors of both armies was worthy of the prize at stake. Abderrahman, the Mohammedan leader, fell in the thick of the fight, and night saw the complete discomfiture of the Moslem hordes. The loss that the sturdy blows of the Germans had inflicted upon them was enormous, the accounts of that age swelling the number killed to the impossible figures of 375,000. The disaster at all events was too overwhelming to permit the Saracens ever to recover from the blow, and they soon retreated behind the Pyrenees.
The young civilization of Europe was thus delivered from an appalling danger, such as had not threatened it since the fearful days of Attila and the Huns. The heroic Duke Charles who had led the warriors of Christendom to the glorious victory was given the surname Martel, the "Hammer," in commemoration of the mighty blows of his huge battle-axe.
CHANGES IN THE CALIPHATE.—During the century of conquests we have traced, there were many changes in the caliphate. Abubekr was followed by Omar (634-644), Othman (644-655), and Ali (655-661), all of whom fell by the hands of assassins, for from the very first dissensions were rife among the followers of the Prophet. Ali was the last of the four so-called "Orthodox Caliphs," all of whom were relatives or companions of the Prophet.
