Treaty of London

26 April 1915

The Treaty of London of 1915 was a secret agreement between the Triple Entente powers, Britain, France and Russia, and Italy. Under it Italy agreed to leave its alliance with Germany and Austria-Hungary and enter the First World War on the Entente side within a month. In return it was promised territory including Trentino, South Tyrol up to the Brenner Pass, Trieste, Istria, much of Dalmatia and other possessions, as well as colonial compensation. Italy declared war on Austria-Hungary in May 1915. After the war Italy received less than had been promised, because of the principles of President Wilson and the creation of Yugoslavia, and the resentment over a mutilated victory fed nationalism and the rise of Fascism. The Bolsheviks published the secret treaties in 1917.
