government; an army of a hundred and twenty thousand soldiers, against a sixth part of that number; and the presence and merit of the caliph Mervan, the fourteenth and last of the house of Ommiyah. Before his accession to the throne, he had deserved, by his Georgian warfare, the honorable epithet of the ass of Mesopotamia; and he might have been ranked amongst the greatest princes, had not, says Abulfeda, the eternal order decreed that moment for the ruin of his family; a decree against which all human fortitude and prudence must struggle in vain. The orders of Mervan were mistaken, or disobeyed: the return of his horse, from which he had dismounted on a necessary occasion, impressed the belief of his death; and the enthusiasm of the black squadrons was ably conducted by Abdallah, the uncle of his competitor. After an irretrievable defeat, the caliph escaped to Mosul; but the colors of the Abbassides were displayed from the rampart; he suddenly repassed the Tigris, cast a melancholy look on his palace of Haran, crossed the Euphrates, abandoned the fortifications of Damascus, and, without halting in Palestine, pitched his last and fatal camp at Busir, on the banks of the Nile. His speed was urged by the incessant diligence of Abdallah, who in every step of the pursuit acquired strength and reputation: the remains of the white faction were finally vanquished in Egypt; and the lance, which terminated the life and anxiety of Mervan, was not less welcome perhaps to the unfortunate than to the victorious chief. The merciless inquisition of the conqueror eradicated the most distant branches of the hostile race: their bones were scattered, their memory was accursed, and the martyrdom of Hossein was abundantly revenged on the posterity of his tyrants. Fourscore of the Ommiades, who had yielded to the faith or clemency of their foes, were invited to a banquet at Damascus. The laws of hospitality were violated by a promiscuous massacre: the board was spread over their fallen bodies; and the festivity of the guests was enlivened by the music of their dying groans. By the event of the civil war, the dynasty of the Abbassides was firmly established; but the Christians only could triumph in the mutual hatred and common loss of the disciples of Mahomet.

Yet the thousands who were swept away by the sword of war might have been speedily retrieved in the succeeding generation, if the consequences of the revolution had not tended to dissolve the power and unity of the empire of the Saracens. In the proscription of the Ommiades, a royal youth of the name of Abdalrahman alone escaped the rage of his enemies, who hunted the wandering exile from the banks of the Euphrates to the valleys of Mount Atlas. His presence in the neighborhood of Spain revived the zeal of the white faction. The name and cause of the Abbassides had been first vindicated by the Persians: the West had been pure from civil arms; and the servants of the abdicated family still held, by a precarious tenure, the inheritance of their lands and the offices of government. Strongly prompted by gratitude, indignation, and fear, they invited the grandson of the caliph Hashem to ascend the throne of his ancestors; and, in his desperate condition, the extremes of rashness and prudence were almost the same. The acclamations of the people saluted his landing on the coast of Andalusia: and, after a successful struggle, Abdalrahman established the throne of Cordova, and was the father of the Ommiades of Spain, who reigned above two hundred and fifty years from the Atlantic to the Pyrenees. He slew in battle a lieutenant of the Abbassides, who had invaded his dominions with a fleet and army: the head of Ala, in salt and camphire, was suspended by a daring messenger before the palace of Mecca; and the caliph Almansor rejoiced in his safety, that he was removed by seas and lands from such a formidable adversary. Their mutual designs or declarations of offensive war evaporated without effect; but instead of opening a door to the conquest of Europe, Spain was dissevered from the trunk of the monarchy, engaged in perpetual hostility with the East, and inclined to peace and friendship with the Christian sovereigns of Constantinople and France. The example of the Ommiades was imitated by the real or fictitious progeny of Ali, the Edrissites of Mauritania, and the more powerful Fatimites of Africa and Egypt. In the tenth century, the chair of Mahomet was disputed by three caliphs or commanders of the faithful, who reigned at Bagdad, Cairoan, and Cordova, excommunicating each other, and agreed only in a principle of discord, that a sectary is more odious and criminal than an unbeliever.

Mecca was the patrimony of the line of Hashem, yet the Abbassides were never tempted to reside either in the birthplace or the city of the prophet. Damascus was disgraced by the choice, and polluted with the blood, of the Ommiades; and, after some hesitation, Almansor, the brother and successor of Saffah, laid the foundations of Bagdad, the Imperial seat of his posterity during a reign of five hundred years. The chosen spot is on the eastern bank of the Tigris, about fifteen miles above the ruins of Modain: the double wall was of a circular form; and such was the rapid increase of a capital, now dwindled to a provincial
