The flag of Egypt Eyalet.
Ottoman Egypt (Egypt Eyalet) was an administrative division of the Ottoman Empire after the conquest of Mamluk Egypt by the Ottomans in 1517. The Ottomans administered Egypt as a province (eyalet) of their empire (Ottoman Turkish: ایالت مصر, romanized: Eyālet-i Mıṣr).[better source needed] It remained formally an Ottoman province until 1914, though in practice it became increasingly autonomous during the 19th century and was under de facto British control from 1882.
