The Italian front (Italian: Fronte italiano; German: Südwestfront) was one of the main theatres of war of World War I. It involved a series of military engagements along the border between the Kingdom of Italy and Austria-Hungary from 1915 to 1918. Following secret promises made by the Entente in the 1915 Treaty of London, the Kingdom of Italy entered the war on the Entente side, aiming to annex the Austrian Littoral, northern Dalmatia and the territories of present-day Trentino and South Tyrol. The front soon bogged down into trench warfare, similar to that on the Western Front, but at high altitudes and with extremely cold winters. Fighting along the front displaced much of the local population, and several thousand civilians died from malnutrition and illness in Kingdom of Italy and Austro-Hungarian refugee camps.[7]
