The thousands who, with uncomely names and barbarous titles, began to crowd the streets of Cairo, occupied a position to which we have no parallel elsewhere. Finding a weak and subservient population, they lorded it over them. Like the children of Israel, they ever kept themselves distinct from the people of the land--but the oppressors, not, like them, the oppressed. Brought up to arms, the best favored and most able of the mamelukes when freed became, at the instance of the Sultan, emirs of ten, of fifty, of a hundred, and often, by rapid leaps, of a thousand. They continued to multiply by the purchase of fresh slaves who, like their masters, could rise to liberty and fortunes. The sultans were naturally the largest purchasers, as they employed the revenues of the state in surrounding themselves with a host of slaves; we read, for example, of one who bought some six thousand. While the great mass pursued a low and servile life, the favorites of the emirs, and specially of the crown, were educated in the arts of peace and war, and, as pages and attendants, gradually rose to the position of their masters--the slave of to-day, the commander, and not infrequently the sultan of to-morrow. From the first, insolent and overbearing, the mamelukes began, as time passed on, to feel their power, and grew more and more riotous and turbulent, oppressing the land by oft-repeated pillage and outrage. Broken up into parties, each with the name of some sultan or leader, their normal state was one of internal combat and antagonism; while, pampered and indulged, they often turned upon their masters. Some of the more powerful sultans were able to hold them in order, and there were not wanting occasional intervals of quiet; but trouble and uproar were ever liable to recur. The Eyyubite princes settled their mamelukes, chiefly Turks and Mongols--so as to keep them out of the city--on an island in the Nile, whence they were called Baharites, and the first mameluke dynasty (1260-1382) was of this race, and called accordingly. The others, a later importation, were called Burjites, from living in the Citadel, or quarters in the town; they belonged more to the Circassian race. The second dynasty (1382-1517) was of these, and, like the Baharite dynasty, bore their name. The mamelukes were for the most part attached faithfully to their masters, and the emirs, with their support, enriched themselves by exactions from the people, with the unscrupulous gains of office, and with rich fiefs from the state. The mamelukes, as a body, thus occupied a prominent and powerful position, and often, especially in later times, forced the Sultan to bend to their will. Such is the people which for two centuries and a half ruled Egypt with a rod of iron, and whose history we shall now attempt to give.
