The chief direct result in the life of the Egyptian people was the virtual destruction of the governing caste of the Mamelukes, the Turks finding it easy to rid themselves of their surviving chiefs and to re-establish the authority of the Sultan.
These dynasties were founded by emancipated mamelukes, who had held high office at court and in camp under powerful amirs, and who, on their death, first became stadtholders for their descendants, and then usurped the throne of their masters.
Later, it allied itself with the Mongols and fought against the Mamelukes, to whom, however, it finally succumbed in 1375.
The objective was unexpected: it may have been chosen by St Louis, because he knew how seriously the power of the sultan was undermined by the Mamelukes, who were in the very next year to depose the Ayyubite dynasty, which had reigned since 1171, and to substitute one of their number as sultan.
The Mamelukes, who are analogous to the janissaries of the Ottoman Turks, were made of sterner and more fanatical stuff; and Bibars, the greatest of these Mamelukes, who had commanded at Gaza in 1244, had been one of the leaders in 1250, and was destined to become sultan in 1260, was the sternest and most fanatical of them all.
