The Constantinople Agreement (also known as the Straits Agreement) comprised a secret exchange of diplomatic correspondence between members of the Triple Entente from 4 March to 10 April 1915 during World War I. France and Great Britain promised to give Constantinople and the Dardanelles (which at the time were part of the Ottoman Empire) to the Russian Empire in the event of victory.[1] Britain and France put forward their own claims, to an increased sphere of influence in Iran in the case of Britain and to annexation of Syria (including Palestine) and Cilicia for France, all sides also agreeing that the governance of the Holy Places and Arabia would be under independent Muslim rule.[2] The Greek government was neutral, but in 1915 it negotiated with the Allies, offering soldiers and especially a geographical launching point for attacks on the Turkish Straits. Greece itself wanted control of Constantinople. Russia vetoed the Greek proposal, because its main war goal was to control the Straits, and take control of Constantinople.[3]
