Since the dissolution of the Soviet Union in 1991, relations between Turkey and Russia have improved, largely on account of trade. The two nations consider each other as a major trading partner. Russia is Turkey’s largest provider of energy, while Turkish companies operate in Russia. Significantly, Turkey’s dictator, Recep Tayyip Erdogan has defied the North Atlantic Treaty Organization (NATO), in which Turkey has been an important member. It announced in September, 2017 its plan to purchase from Russia’s strongman, Vladimir Putin, the S-400 surface-to-air missile system, despite strong objections from the U.S. and all other members of NATO.
During the Cold-War, Muslim but secular Turkey was the southern anchor of the West, and of the U.S. in particular, against the Soviet Union. U.S. President John F. Kennedy had nuclear missiles placed in Turkey aimed at Moscow. When, however, the Cuban missile crisis occurred in 1962, as a price for the Soviets removing their nuclear missiles from Cuba, which intended to threaten the U.S., the U.S. was secretly compelled to remove its missiles from Turkey as part of the deal. Turkey was allied with the West, and had sent troops to fight alongside the U.S. during the Korean War.
The story of Russo-Turkish relations is one of imperial wars between the Russian Romanov Tsars and the Ottoman Turkish Sultans, both with imperial ambitions to expand their respective territories. Hostilities between these two empires began in the last quarter of the seventeenth century. The first clashes occurred in the Ukraine, where the Turks held large portions of the land, and enslaved Slavic boys and girls, as well as women to serve as concubines in harems of the Ottoman Sultan/Caliphs. The Crimea was another stage in the 1687-1689 war between the two empires.
