Battle of Ridaniyya and the fall of the Mamluk state

The battle of al-Ridaniyya, 923 AH (1517 CE), between the Ottoman sultan Selim I and the Mamluks under Tuman Bay, ended with the fall of the Mamluk state. ²

al-Sallabi relates that Selim sent to Tuman Bay asking him to obey the Ottoman state. The Mamluks mocked his messenger and then killed him, so Selim decided on war and marched toward Egypt. ²

The Ottomans won a crushing victory at the battle of Gaza and then at al-Ridaniyya, and Selim entered Egypt. al-Sallabi quotes Jarmard al-Nasiri as saying that it had not been heard that Egypt suffered such a calamity since it became a land of Islam. ²

al-Sallabi relates that Selim told Tuman Bay that he had come with the fatwa of the scholars of the lands, and that he had been heading to fight the Safavids and the Portuguese, but turned toward Egypt when al-Ghawri agreed with the Safavids and marched to Aleppo. This is Selim's own account, as attributed to him in the book. ²
