»4 Egypt was at first a servile militia, then a military caste, and finally a ruling class, was introduced by the Saracens when at the height of their power under Saladin, and was afterwards imitated by the Turks in their Janissaries. Slavery had indeed been from the earliest days of Islam the short cut to power, and Saladin himself, like many of the early Sultans, began life as a slave. But in Egypt we find one of the most extraordinary examples of a body of alien slave-guards becoming a governing aristocracy simply through not assimilating or even associating with the native population. Already in 1250 the Mamelukes were strong enough to murder the Fatimite Sultan, and nominate future Sultans from among their own chiefs. That the Mamelukes were able to maintain their alien authority over Egypt for no less than five centuries was due to their regularly recruiting their ranks from the pick of emancipated slaves belonging to the white races of the Caucasus, than which there are no finer types in the world. The majority were Georgians, and f< Gorz," the Egyptian word for their regime, is clearly a corruption of "Grouz," their name in their own language. They married invariably women of their own race, but this would not alone have saved their type and tyranny with- out fresh blood. For their families, like those of all other Aryan races in Egypt, degenerated and died out in the second or third generation. Thus, though they acquired a semi-feudal, semi-fiscal hold on the land, they never became a hereditary class, while their alien authority and their association with the no less alien Turks fused in a common subjection the Egyptian Arabs, Nubians, and even Copts, in spite of differences of race and religion. Taxation of the fertile soil of Egypt and of the sub- missive fellaheen, supplemented by toll-takings from the transit trade between Europe and Asia, produce4 enough
