Bab Zuweila
Continuing the westward expansion of the Mongol Empire, the armies of Hulagu Khan captured and sacked Baghdad in 1258, along with the Ayyubid capital of Damascus sometime later. Hulagu sent envoys to Cairo demanding Qutuz surrender Egypt, to which Qutuz responded by killing the envoys and displaying their heads on the Bab Zuweila gate of Cairo. Shortly after this, Hulagu returned to Mongolia with the bulk of his army in accordance with Mongol customs, leaving approximately 10,000 troops west of the Euphrates under the command of general Kitbuqa.
