Mohammed's successor assumed the title of caliph. Under him the Arabs went forth to conquer the great territories to the north of them, belonging to the Persians and the Roman emperor at Constantinople. They met with marvelous success. Within ten years after Mohammed's death the Arabs had established a great empire with its capital at Damascus, from whence the caliph ruled over Arabia, Persia, Syria, and Egypt. In the following decades new conquests were made all along the coast of Africa, and in 708 Tangier was taken and the Arabs could look across the Straits of Gibraltar to Spain.[37]

The Arabs in Spain.
The kingdom of the West Goths was in no condition to defend itself when a few Arabs and a much larger number of Berbers, inhabitants of northern Africa, ventured to cross over. Some of the Spanish towns held out for a time, but the invaders found allies in the numerous Jews who had been shamefully treated by their Christian countrymen. As for the innumerable serfs who worked on the great estates of the aristocracy, a change of landlords made very little difference to them. In 711 the Arabs and Berbers gained a great battle, and the peninsula was gradually overrun by new immigrants from Africa. In seven years the Mohammedans were masters of almost the whole region south of the Pyrenees. They then began to cross into Gaul and took possession of the district about Narbonne. For some years the duke of Aquitaine kept them in check, but in 732 they collected a large army, defeated the duke near Bordeaux, advanced to Poitiers, where they burned the church, and then set out for Tours.
Battle of Tours, 732.
Charles Martel at once sent out a summons to all who could bear arms and, in the same year, met and repulsed the Mohammedans near Tours. We know very little indeed of the details of the conflict, but it is certain that the followers of Mohammed retreated and that they never made another attempt to conquer western Europe.
