Tuman Bay II

Al-Ashraf Abu Al-Nasr Tuman Bay (Arabic: الأشرف أبو النصر طومان باي), better known as Tuman Bay II and Tumanbay II (طومان باي; c. 1476 – 15 April 1517) was the Mamluk Sultan of Egypt before the country's conquest by the Ottoman Empire in 1517. He ascended to the sultanic throne during the final period of Mamluk rule in Egypt, after the defeat of Sultan Al-Ashraf Qansuh al-Ghawri by Ottoman Sultan Selim I at the Battle of Marj Dabiq the year prior. He was the last person to hold the title of Sultan of Egypt until the re-establishment of the sultanate 397 years later under Hussein Kamel in 1914.

A Circassian who like his predecessors, had been a domestic slave of the palace, Tuman gradually rose to the position of prime minister, an office he held until the departure of Sultan Al-Ashraf Qansuh al-Ghawri, who left him in charge of Cairo. His rise to power was clouded by conflict in Syria, disordered troops, distracted emirs, and a mercenary horde of Mamluks.
