London, Treaty of 1915

a secret treaty between Great Britain, Russia, and France on one side and Italy on the other; signed in London on Apr. 26, 1915, it defined conditions for Italy’s entrance into World War I (1914-18) on the side of the Entente.

Italy obligated itself in no more than one month’s time to declare war on Austria-Hungary and to act (without specification of an exact time limit) against “all & enemies” of the Entente. Italy was promised as a “blood payment” a number of territories along the Adriatic (including Trentino in the southern Tirol) and Aegean seas and in Asia Minor, Africa, and elsewhere.
