معركة مرج دابق
Al-Ashraf Abu Al-Nasr Tuman bay (), better known as Tuman bay II (), was the last Sultan of Egypt before the country's conquest by the Ottoman Empire in 1517. He acceded to the sultanic throne during the final period of Mamluk rule in Egypt, after the defeat of his predecessor, Sultan Al-Ashraf Qansuh al-Ghawri by Ottoman Sultan Selim I at the Battle of Marj Dabiq in 1516. He was the last person to hold the title of Sultan of Egypt prior to the re-establishment of the sultanate 397 years later under Hussein Kamel in 1914.
