While the Eastern Empire of Islam was passing into the hands of Persians and Turks, we find the Arabs still holding their own in Syria and Mesopotamia down to the end of the tenth century. These Arab and generally nomadic dynasties were seldom of much account. The Ḥamdánids of Aleppo alone deserve to be noticed here, and that chiefly for the sake of the peerless Sayfu ’l-Dawla, a worthy descendant of the tribe of Taghlib, which in the days of heathendom produced the poet-warrior, ‘Amr b. Kulthúm. ‘Abdulláh b. Ḥamdán was appointed governor of Mosul and its dependencies by the Caliph Muktafí in 905 A.D., and in 942 his sons Ḥasan and ‘Alí received the complimentary titles of Náṣiru ’l-Dawla (Defender of the State) and Sayfu ’l-Dawla (Sword of the State). Two years later Sayfu ’l-Dawla captured Aleppo and brought the whole of Northern Syria under his dominion. During a reign of twenty-three years he was continuously engaged in harrying the Byzantines on the frontiers of Asia Minor, but although he gained some glorious victories, which his laureate Mutanabbí has immortalised, the fortune of war went in the long run steadily against him, and his successors were unable to preserve their little kingdom from being crushed between the Byzantines in the north and the Fáṭtimids in the south. The Ḥamdánids have an especial claim on our sympathy, because they revived for a time the fast-decaying and already almost broken spirit of Arabian nationalism. It is this spirit that speaks with a powerful voice in Mutanabbí and declares itself, for example, in such verses as these:--[503] "Men from their kings alone their worth derive, But Arabs ruled by aliens cannot thrive: Boors without culture, without noble fame, Who know not loyalty and honour's name. Go where thou wilt, thou seest in every land Folk driven like cattle by a servile band." [Sidenote: The circle of Sayfu ’l-Dawla.]
