The Russo-Turkish War of 1676–1681, a war between the Tsardom of Russia and Ottoman Empire, caused by Turkish expansionism in the second half of the 17th century. After having captured and devastated the region of Podolia in the course of the Polish–Turkish War of 1672–1676, the Ottoman government strove to spread its rule over all of the Right-bank Ukraine with the support of its vassal (since 1669), Hetman Petro Doroshenko. The latter’s pro-Turkish policy caused discontent among many Ukrainian Cossacks, which would elect Ivan Samoilovich (Hetman of the Left-bank Ukraine) as a sole Hetman of all Ukraine in 1674.
