The History of the Decline and Fall of the Roman Empire - Edward Gibbon [1808]
After the revolt of Spain from the temporal and spiritual supremacy of the Abbassides, the first symptoms of disobedience broke forth in the province of Africa. Ibrahim, the son of Aglab, the lieutenant of the vigilant and rigid Harun, bequeathed to the dynasty of the Aglabites the inheritance of his name and power. The indolence or policy of the caliphs dissembled the injury and loss, and pursued only with poison the founder of the Edrisites, ^104 who erected the kingdom and city of Fez on the shores of the Western ocean. ^105 In the East, the first dynasty was that of the Taherites; ^106 the posterity of the valiant Taher, who, in the civil wars of the sons of Harun, had served with too much zeal and success the cause of Almamon, the younger brother. He was sent into honorable exile, to command on the banks of the Oxus; and the independence of his successors, who reigned in Chorasan till the fourth generation, was palliated by their modest and respectful demeanor, the happiness of their subjects and the security of their frontier. They were supplanted by one of those adventures so frequent in the annals of the East, who left his trade of a brazier (from whence the name of Soffarides) for the profession of a robber. In a nocturnal visit to the treasure of the prince of Sistan, Jacob, the son of Leith, stumbled over a lump of salt, which he unwarily tasted with his tongue. Salt, among the Orientals, is the symbol of hospitality, and the pious robber immediately retired without spoil or damage. The discovery of this honorable behavior recommended Jacob to pardon and trust; he led an army at first for his benefactor, at last for himself, subdued Persia, and threatened the residence of the Abbassides. On his march towards Bagdad, the conqueror was arrested by a fever. He gave audience in bed to the ambassador of the caliph; and beside him on a table were exposed a naked cimeter, a crust of brown bread, and a bunch of onions. "If I die," said he, "your master is delivered from his fears. If I live, this must determine between us. If I am vanquished, I can return without reluctance to the homely fare of my youth." From the height where he stood, the descent would not have been so soft or harmless: a timely death secured his own repose and that of the caliph, who paid with the most lavish concessions the retreat of his brother Amrou to the palaces of Shiraz and Ispahan. The Abbassides were too feeble to contend, too proud to forgive: they invited the powerful dynasty of the Samanides, who passed the Oxus with ten thousand horse so poor, that their stirrups were of wood: so brave, that they vanquished the Soffarian army, eight times more numerous than their own. The captive Amrou was sent in chains, a grateful offering to the court of Bagdad; and as the victor was content with the inheritance of Transoxiana and Chorasan, the realms of Persia returned for a while to the allegiance of the caliphs. The provinces of Syria and Egypt were twice dismembered by their Turkish slaves of the race of Toulon and Ilkshid. ^107 These Barbarians, in religion and manners the countrymen of Mahomet, emerged from the bloody factions of the palace to a provincial command and an independent throne: their names became famous and formidable in their time; but the founders of these two potent dynasties confessed, either in words or actions, the vanity of ambition. The first on his death-bed implored the mercy of God to a sinner, ignorant of the limits of his own power: the second, in the midst of four hundred thousand soldiers and eight thousand slaves, concealed from every human eye the chamber where he attempted to sleep. Their sons were educated in the vices of kings; and both Egypt and Syria were recovered and possessed by the Abbassides during an interval of thirty years. In the decline of their empire, Mesopotamia, with the important cities of Mosul and Aleppo, was occupied by the Arabian princes of the tribe of Hamadan. The poets of their court could repeat
