The Ottoman–Mamluk War of 1516–1517 was the second major conflict between the Egypt-based Mamluk Sultanate and the Ottoman Empire, which led to the fall of the Mamluk Sultanate and the incorporation of the Levant, Egypt, and the Hejaz as provinces of the Ottoman Empire. The war transformed the Ottoman Empire from a realm at the margins of the Islamic world, mainly located in Anatolia and the Balkans, to a huge empire encompassing much of the traditional lands of Islam, including the cities of Mecca, Cairo, Damascus, and Aleppo. Despite this expansion, the seat of the empire's political power remained in Constantinople.
