The turn of the XVII-XVIII centuries was one of the turning points in the history of the Crimean Khanate. The port increasingly pacified the" warlike impulses", i.e. raids, of the Tatars. After the Treaty of Bakhchisarai (1681), the Ottoman Turks pushed Crimea away from the khanate's solution of "their" problems in relations with Moscow. The actions of the Sultan's court to implement the Treaty of Constantinople of 1700 (which, among other things, limited Tatar invasions of Russia and eliminated the "wake") caused serious objections in the Crimea, which were expressed in the rebellion of Devlet Giray II [Sanin, 1993, pp. 275-279], who was exiled to fr.

At the turn of the XVII-XVIII centuries, the Kuban Cossacks became a powerful force, whose military traditions, having passed the formation on the Don, were developed in the North Caucasus. There is a well-known case when the Crimean Khan resorted ... Read more
