Russia and the Turkish Straits: A Revaluation of the Origins of the Problem

The USSR placed on the agenda of the Big Three wartime conference at Yalta in February 1945 the question of the Turkish Straits. Of this 200-mile natural channel, less than 60 miles—the Bosphorus coming from the Black Sea and the Dardanelles going to the Aegean—are true straits, joined by the inland sea of Marmara. Ever since 1841 the transit of naval vessels through the Straits has been regulated by international agreement. The latest regime was established by a convention signed at Montreux in July 1936, authorizing Turkey to remilitarize the strategic waterway and, if it were “threatened with imminent danger of war” or actually engaged in war (Articles 20 and 21), to permit or disallow at its discretion the passage of warships through the narrows.
