But despite the severity of Oriental rule, Spain continued a tributary to the Eastern califs until about the middle of the century in which it was conquered, when (as we shall see in due course) an independent califate was established in Cordova. Musa had left as emir in his absence his favourite son Abdalasis, who governed the conquered territory wisely, but had the misfortune, during his father’s absence, to see and fall in love with beautiful Exilona, the unhappy widow of the departed King Roderick. They were married; but as he was a Moslem and she a Christian, soon there began murmurs among their subjects, notwithstanding the generous nature of Abdalasis, who had ever in mind their well–being. These rumours reached the ears of the Calif, cruel and bloodthirsty Suleiman, and he sent orders that the devoted pair should be murdered. His commands were obeyed: both were basely killed while at morning prayers, and the head of Abdalasis was embalmed and sent in a casket to Syria, to the court of the Calif. The unfortunate Musa was in attendance at the court, and when the casket arrived the Calif took out the head of Abdalasis and held it up before his victim: “Dost thou know this head?” he demanded. Musa gazed in anguish. “Yes,” he murmured, “well do I know it; and may the curse of God light upon him who has destroyed a better man than himself!” The stricken father did not long survive this terrible stroke; but the wrath of Suleiman was not appeased until the other sons of Musa, whom he had left at important posts in Africa, were also numbered with the dead. Still, despite the ingratitude and cruelty of the Califas, able generals were found to carry on the war for Islam, until even the Pyrenees were leaped and the Moslem hosts invaded France. It seemed as though all Europe would become subject to the bonds of the Arabs, and soon be brought to acknowledge the “one God and Mohammed his prophet.” But in the year 732, twenty–one years after the invasion of Spain, the tide was turned at Tours, when Charles Martel slew thirty thousand Moslems and turned back the remainder, eventually to retreat to the land whence they had come. No other country suited them so well, and here they lived, they and their descendants, from first to last, more than eight hundred years. [Illustration] CHAPTER VI. THE WESTERN CALIFATE. Within three years after their first appearance in Spain the Moors had subjected nearly the entire territory, save only a restricted region in the north and west. For about fifty years thereafter they were governed by emirs sent from the califate of Damascus, and the last of some twenty emirs was one Yusef, an Abbasside. To understand the Arab terms which we are now compelled to use in relating this portion of Spain’s history, we must transport ourselves once again to the Orient, and glance at the line of califs, or caliphs, successors to Mahomet, or Mohammed, which had carried on his conquests for many years.
