The city of Caffa and its surroundings were first made an Ottoman dominion after the Turks overran the Genoese in 1475, after which a sanjak centred on Caffa was created.[3] The Eyalet of Kefe was formed in 1568 as a beylerbeylik.[4] By the 17th-century accounts of Evliya Çelebi, its sanjaks were "ruled by Voivodas immediately appointed by the Ottoman Sultan and not by the Khans".[5] The eyalet was annexed to a briefly independent Khanate of Crimea as a result of the Treaty of Küçük Kaynarca of 1774.[6] The Khanate itself would be annexed by Russia in 1783.[7]
