Constantinople Agreement

Also Known As Straits Agreement
Diplomatic Correspondence and Secret Agreements

The Constantinople Agreement resulted from a secret exchange of diplomatic correspondence among members of the Triple Entente between 4 March and 10 April 1915, during the First World War. Under its terms, France and Great Britain agreed that, in the event of an Entente victory, Constantinople and the Dardanelles would be given to the Russian Empire, while Britain and France put forward their own claims, respectively to an increased sphere of influence in Persia and to the annexation of Syria and Cilicia. The three powers also agreed that the Holy Places and Arabia would come under independent Muslim rule. Greece, though technically neutral until June 1917, negotiated with the Allies in 1915 over a geographical launching point for attacks on the Turkish Straits, seeking control of Constantinople for itself, a proposal Russia vetoed to protect its own aim of controlling the Straits and the city.

Was Greece part of the Constantinople Agreement?

No. Russia vetoed the Greek bid for Constantinople in 1915.

No. The agreement came from a secret exchange of letters among members of the Triple Entente, and Greece was not one of those three powers. The Greek government remained technically neutral until June 1917, but in 1915 it negotiated with the Allies and wanted control of Constantinople for itself. Russia vetoed the Greek proposal, because its own main war aim was to control the Straits and the city.
