Excerpts from Books and Wikipedia
"The Burji dynasty ruled Egypt from 1382 until 1517. It proved especially turbulent, with short-lived sultans. Political power-plays often became important in designating a new sultan. During this time Mamluks fought Timur Lenk and conquered Cyprus. . . . The relationship between the Ottomans and the Mamluks had been adversarial since the Fall of Constantinople to the Ottomans in 1453; both states vied for control of the spice trade, and the Ottomans aspired to eventually taking control of the Holy Cities of Islam. An earlier conflict, which lasted from 1485 to 1491, had led to a stalemate. . . . In 1517 the Ottoman Turks and their Sultan Selim I defeated the Mamluks with the capture of Cairo on January 20. The centre of power transferred from Cairo to Constantinople. However, the Ottoman Empire retained the Mamluks as an Egyptian ruling class and the Mamluks and the Burji family succeeded in regaining much of their influence, but remained technical vassals of the Ottomans."
