But this slave was his master: the viziers or sultans had usurped the supreme administration of Egypt; the claims of the rival candidates were decided by arms; and the name of the most worthy, of the strongest, was inserted in the royal patent of command.
The factions of Dargham and Shawer alternately expelled each other from the capital and country; and the weaker side implored the dangerous protection of the sultan of Damascus, or the king of Jerusalem, the perpetual enemies of the sect and monarchy of the Fatimites.

By his arms and religion the Turk was most formidable; but the Frank, in an easy, direct march, could advance from Gaza to the Nile; while the intermediate situation of his realm compelled the troops of Noureddin to wheel round the skirts of Arabia, a long and painful circuit, which exposed them to thirst, fatigue, and the burning winds of the desert.
The secret zeal and ambition of the Turkish prince aspired to reign in Egypt under the name of the Abbassides; but the restoration of the suppliant Shawer was the ostensible motive of the first expedition; and the success was intrusted to the emir Shiracouh, a valiant and veteran commander.

Dargham was oppressed and slain; but the ingratitude, the jealousy, the just apprehensions, of his more fortunate rival, soon provoked him to invite the king of Jerusalem to deliver Egypt from his insolent benefactors.

To this union the forces of Shiracouh were unequal: he relinquished the premature conquest; and the evacuation of Belbeis or Pelusium was the condition of his safe retreat.

As the Turks defiled before the enemy, and their general closed the rear, with a vigilant eye, and a battle axe in his hand, a Frank presumed to ask him if he were not afraid of an attack.
