In less than a hundred years after the death of Mohammed the Moslem faith had spread from Arabia through Syria and Asia Minor to Persia and India, while Westward it had overrun Egypt and penetrated along the northern shore of Africa to the Pillars of Hercules. Hence in 711 A.D. it crossed into Spain. While the leaders, under the generalship of Musa, viceroy of the Omayyad Caliphate of Damascus, were all Arabs, they had enlisted in their army the warlike tribes of Mauritania, the ancient kingdom now represented by Morocco and Algeria. Hence the name of Moors (Mauri) which distinguishes the invaders of Spain. Twenty years sufficed to make them masters of the Peninsula, the little northwestern country of Asturias alone retaining its independence. Twenty years later disintegration crept also into the ranks of the conquerors. Abd-er-Rahman established an independent caliphate in Cordova. His ambition was to raise it to a position in the Western world such as was held by Bagdad, Damascus and Delhi in the East; furthermore to make Cordova the Mecca of the faithful in the West. Thus was begun by this Caliph the Mesquita or chief Mosque, which under succeeding Caliphs was enlarged and beautified until it became a fitting monument of the ideals of Islam in its period of most splendid pride and noblest enlightenment. For nearly three hundred years Cordova was the center of an ordered government, which not only fostered the refinement of the arts and crafts in the cities and spread its network of highly organised agricultural labor throughout the country districts, but also a University of philosophy and science that made it the resort of scholars, not only Moslem but Christian. Cordova, in fact, played a conspicuously brilliant part in that phase of the Moslem ascendency which is apt to be overlooked; its share in perpetuating and advancing the Hellenic culture, which otherwise might have been lost in the Dark Ages succeeding the fall of the Roman Empire.
