The Ottoman forces of Selim I defeated the Mamluk forces under Al-Ashraf Tuman bay II. The Turks marched into Cairo, and the severed head of Tuman bay II, Egypt’s last Mamluk Sultan, was hung over an entrance gate in the Al Ghourieh quarter of Cairo. The Ottoman grand vizier, Hadım Sinan Pasha, was killed in action. The Mamluk sultanate comes to an end and the center of power transfers to Constantinople, but the Ottoman Empire allow the Mamluks to remain as the ruling class in Egypt under their power.
