Principality of Theodoro
In 1475 the Ottoman forces, under the command of Gedik Ahmet Pasha, conquered the Greek Principality of Theodoro and the Genoese colonies at Cembalo, Soldaia, and Caffa (modern Feodosiya). Thenceforth the khanate was a protectorate of the Ottoman Empire. The Ottoman sultan enjoyed veto power over the selection of new Crimean khans. The Empire annexed the Crimean coast but recognized the legitimacy of the khanate rule of the steppes, as the khans were descendants of Genghis Khan.
