End of Italian domination on the Great Sea laid capture the Turkish Sultan Mehmet II of Constantinople 29 May 1453 The Turks did not want to endure the Italian colonies on the shores of the Great Sea, and all of them were destroyed in the 1475-1480 biennium. Most of the Italians had been killed or sold into slavery. Only a few hundred managed to escape through the Grand Duchy of Lithuania and to return home. Thousands of Italians were in the Crimea under the rule of the Turks and Tatars. Gradually, their language clogged Turkism, many married Tatarka and converted to Islam. By the middle of the XVIII century in the Crimea were only a few hundred descendants of the colonists, who spoke in a mixture of Italian and Tatar languages, and still professing Christianity. By the end of the XVIII century all traces of them were lost.
