After the World War erupted, the pressure by both sides for Italy to enter the war increased. On April 26, 1915, the Triple Entente and Italy signed a secret agreement, called the Treaty of London, that stipulated the terms of Italy's participation in World War I against the Germany-Austrian Alliance. If Italy declared war on Germany and the Entente emerged victorious, Italy would be awarded territories of the House of Habsburg in the Southern Alps and in the Balkans, specifically the regions of Trentino and the South Tyrol (up to the northern limit of the Brenner Pass), the Friuli-Julian area, Trieste and the surrounding area, Istria, and the North of the Dalmatian Cost including the city of Šibenik. Other possible territories included in the treaty were the city of Vlorë in Albania, some part on the south Anatolian coast, as well as a share of the German colonial empire.
