Mamluk Sultanate (Cairo) The Mamluk Sultanate (Arabic: سلطنة المماليك‎ ‎ "Salṭanat al-Mamālīk") was a medieval realm spanning Egypt, the Levant, and Hejaz. It lasted from the overthrow of the Ayyubid dynasty until the Ottoman conquest of Egypt in 1517. Historians have traditionally broken the era of Mamlūk rule into two periods—one covering 1250–1382, the other, 1382–1517. Western historians call the former the "Baḥrī" period and the latter the "Burjī" due to the political dominance of the regimes known by these names during the respective eras. Contemporary Muslim historians refer to the same divisions as the "Turkish" and "Circassian" periods in order to stress the change in the ethnic origins of the majority of Mamlūks.
