Sandjar, if not the most dangerous, was yet, at this period, the most powerful of the enemies of the Ismailites. With the exception of the phantom of spiritual power, which sat on the throne of the khalifat, and whose nominal superiority was acknowledged by the Asiatic princes in their Friday’s prayers, the most powerful sovereigns either held their states in fee, as the vassals of the Sultan Sandjar, or governed them as his lieutenants. As, in the ancient Persian empire, the seven satraps of the distant large provinces, surrounded the throne of the great king as viceroys (like the seven Amshaspande collected round the throne of Ormusd), so the rulers, of seven powerful dignities, acknowledged the Sultan Sandjar as the source of their power; which, indeed, enfeebled by distance, operated less powerfully on the extreme points of the circumference, than in the centre. The Indian provinces of Multan and Gur, immediately to the south of Khorassan, were governed by the Sultan of the Gasnewides, Behramshah, and him of the Gurides, Hossein Jehansus (world burning). Ahmed, the son of Soleiman, whose frequent rebellions had brought upon him as frequent punishments, ruled in northern Transoxana; and the adjacent province of Khowaresm was held in fief by, first, Kotbeddin, then his son, Itsis, two great court and hereditary dignities, who likewise held the office of chief cup-bearer. In middle Persia, reigned the Sultan Mahmud, the Seljukide, under the guidance of his uncle Sandjar; and in the northern and western provinces, Aserbijan and Irak, the two dynasties of the Atabegs, founded by Amadeddin Ben Senji and the Turcoman Ildigis, acknowledged him as paramount lord. As the two powerful families of the Gasnewides and Seljukides, after reigning more than a century, were nodding to their fall, and the dynasties of the Atabegs were shooting up into multifarious branches, we think a few words relative to the origin of the latter not unsuitable.
